LARISSA - LARsen Ice Shelf System, Antarctica, a NSF-funded project.
We are conducting an integrated, multi-disciplinary field program to address the rapid and fundamental changes occurring in the Antarctic Peninsula region as a consequence of the abrupt collapse of the Larsen B Ice Shelf in the fall of 2002. A profound transformation in ecosystem structure and function is occurring in coastal waters of the western Weddell Sea. This transformation appears to be yielding a redistribution of energy flow between chemoautotrophic and photosynthetic production, and to be causing the rapid demise of the extraordinary seep ecosystem discovered beneath the ice shelf, providing an ideal opportunity to test fundamental paradigms in ecosystem evolution.

Rothera British station

We were first treated to a tour of the base and a walk around Rothera
 Point. The base itself consists of a large science laboratory called the 
Bonner Lab which also houses the dive locker, Admiralty House which is used
 for accommodation, the new and old Bransfield buildings and Fuchs House,
 where all field equipment and recreational skiing/snowboarding gear is kept
. The new Bransfield building was opened in 2007 and houses all 
the communal space at Rothera, including the mess (or dining room),
 library, bar and the base shop, which sells clothing, postcards and other
 souvenirs. The view from the mess has got to be one of the best dining hall 
views in the Southern Ocean! Rothera also has its own 1-km
runway, which is utilized by two types of BAS aircraft, the DASH-7 and the
 Twin Otter. These aircraft fly people in and out of Rothera from the
 Falklands (DASH-7), and are also used to deploy field parties onto the
 ice-sheet and to remote field stations further south (Twin Otters). An
 American Twin Otter is being used by our glaciologists to access their 
remote field sites from Rothera’s airstrip.

The new Bransfield building opened in 2007 looking out over
 South Cove. 

Walking around the point gave everyone a great opportunity to stretch their 
legs, relax and appreciate the scenery and wildlife local to Rothera. This 
included Weddell seals and Adelie penguins. We also paid a
 visit to the base shop to buy our own little memento of the trip and
 postcards to send to family and friends.

My evening was spent reminiscing with old Rothera friends and socializing
 with the new ones I have made onboard the NB Palmer. After several games of 
pool, darts and a eight-a-side football (soccer) game by the soccer buffs,
 it was time to return to the ship and for me to say goodbye to Rothera for
 a second time. A great time was had by everyone and all onboard were 
grateful to the Rotherians for their warm welcome and their hospitality. 

Visiting Rothera, for me at least, was almost like coming home. Every thing
 and everyone felt very familiar, and apart from the new Bransfield
 building, the base itself had not changed. It almost felt like I had never

Sailing back to the Weddell Sea

21-29 January. After nearly one month at sea, we are finally heading for our
primary study sites on the east side of the Antarctic Peninsula in the 
Weddell Sea (near Cape Disappointment; see the map a few posts ago). Until now we have been
 locked out of the Weddell Sea by an unseasonably high concentration of sea
 ice, forced to conduct helicopter operations from the west side, trying to
 fly over the mountainous peninsula. On all but three days,
the clouds have been so low that helo operations were cancelled leaving us 
to study fjords on the west side of the Peninsula. While fascinating,
 these fjords are not the focus of our LARISSA Project, designed to assess 
the ecosystem impacts of the climate-change induced melting of the Larsen B
Ice Shelf. Thus, while we have been surrounded by beautiful scenery, 
enhanced by the passage of a 65-foot French yacht (picture below), our spirits 
have been low: we have been planning for years to conduct this exciting 
climate-change research in the Weddell Sea and we are unlikely to get a 
second chance!

One of our helicopters flying from the ship over the mountains 
of the Antarctic Peninsula at Barilari Bay. These rides can be a thrill a
 minute in the downdrafts of the catabatic winds coming down off the 

65-foot French yacht we met cruising in Antartica. She is 
dwarfed by the icebergs. On a day like this, the Antarctica Peninsula
scenery is otherworldly. However, when the winds pick up, every bergie bit 
(small chunks of glacial ice) is a potential reef!

At long last, two developments have brightened our prospects. The first
 was the recognition that much of the glaciology work atop the Peninsula 
could be conducted by Twin Otter (or ski plane) flights from the British
 Base at Rothera, on west side of the Peninsula. This allowed us to drop 
our 5 glaciology colleagues off at Rothera, freeing the ship to head back
 for the Weddell without compromising the terrestrial components of LARISSA
 (even if the ship gets stuck in the ice!). Our trip south to Rothera
 passed by whimsically named islets (including Beer Island and Hennessey 
Island, to torment our teetotalling ship!) and through narrow passages, 
included the Tickle Channel (picture below), which fortunately failed to 
tickle our ship’s bottom. At Rothera Base we received a warm welcome 
from our British colleagues as well as the wildlife. At the
 end of our 12-hour visit, we had an international soccer match (in which
 the Brits exhibited their World-Cup prowess) followed by a party in 
Rothera’s lounge which ended as midnight tolled and our ship departed
 Rothera Harbor (with moons up)!

south to Rothera Base. Seals and penguins dot the bergie bits in the
channel. The icebergs tickle the sides of the ship.

The residents of Rothera Base are so friendly that even the
crabeater seals will offer a kiss! "Don't show my wife!!"

The second positive development for LARISSA came from satellite images of
 the Weddell Sea -- the ice is starting to break out! This has been
 precipitated by long-awaited southwesterly winds combined with warming
 summer temperatures in the Weddell Sea. We are now racing around the tip 
of the Antarctic Peninsula once again, hoping to find, at most, broken ice
flows and leads (i.e., channels) through which the ship can maneuver. If 
all goes well, we still may have time to complete our oceanographic 
program, exploring animal colonization and cold-seep biotas at the seafloor 
under the recently broken out Larsen B Ice Shelf.

Because of our scientific difficulties, the cruise thus far has been
 bittersweet. Normally, after a month at sea, one falls into a rhythm
 characteristic of the ship’s routine, the scientific sampling program,
 and the unique suite of shipboard companions. This cruise has remained
 rythmless through forced changes in plans and shipboard companions on
 nearly a daily basis. One clear message is that research expeditions to
 Antarctica must be, if anything, flexible and opportunistic. Modern
oceanographic technology is still no match for a frozen Southern Ocean. 
However, as the sea ice wanes we now all hope to address our core
 oceanography program, and to begin sampling intensively around the clock. 
Despite the ice delays, the sea ice will become our friend once on we reach
 our oceanographic stations because it calms the seas, allowing our sampling
devices (such as box cores, megacores and yoyo cameras (picture below) to
 work at high efficiency.

We have just entered the fast ice – a featureless plain stretching white
 to the horizon. The scraping and growling begins anew! We hope Poseidon
 allows us to pass through the sea ice to our stations!!

The intrepid Yoyo Camera being lowered into the ocean in
Barilari Bay. This camera is raised and lowered (or "yoyo-ed") near the
seafloor, allowing the lead weight on the end of the line to trip the
camera. In this way, we get about 100 high quality pictures of the 
seafloor and its denizens over a distance of about 1 km (see picture a few posts earlier).

Danco Coast Fjords

14-21 January We have spent the past week along the Danco Coast on the west Antarctic Peninsula (64 to 66 degrees south latitude), working in fjords carved by massive glaciers. Our primary LARISSA Project goal here is to hug the coast across the peninsula from our geological and glacial studies sites, hoping to send teams of geologists by helicopter over the mountains to their work areas. This requires clear flying weather simultaneously on both sides of the Peninsula (a 6000 ft mountain range), which occurs infrequently. The weather has been cloudy for the last week, precluding helicopter operations, but allowing us to study the oceanography of the Danco Coast fjords.

The Fjords of the west Antarctica Peninsula are oceanographically extremely interesting because they contain “tidewater glaciers”, i.e., glaciers calving icebergs directly into the ocean. In addition, the Antarctic Peninsula fjords have only opened relatively recently (in the last few thousand years), i.e., they represent early stages in the transition of fjords from ice-choked polar to ice-free temperate ecosystems. The oceanography and seafloor ecology of of fjords have been intensively studied in Norway, Canada and Alaska, but these are warm fjords compared to the Antarctic Peninsula and contain rapidly melting glaciers or no glaciers at all. The marine ecosystems of the Antarctic Peninsula fjords are likely to be fundamentally different (e.g., they have relatively little input of glacial meltwater and rock flour) and yet they have been little studied. Thus, while waiting to complete our helicopter operations, the oceanographers on board the NB Palmer are conducted studies of the ecology of the Peninsula Fjords.

Abundant brittle stars, sea spiders, spoon worms, and starfish on 2 square meters of seafloor at a depth of 600 m in Flandres Bay fjord.

After studying two fjords near Anvers Island, we are now heading south to Barilari Bay, a fjord south of Cape Garcia on the Graham Coast. If the weather clears, we hope to send glaciologists on to the top of the Peninsula to emplace GPS units to measure glacial movement. However, since the weather has remained cloudy, preventing helo operations since we arrive on the west side of the Peninsula more than one week ago, we are quite worried that we can complete the helicopter transfers. At least we can explore the ecosystem of another fjord, working with truly breathtaking backdrops.

Thursday, January 21, 2010

13 January - This morning saw us progress further through the Gerlache Strait and into a glacial fjord named Flandres Bay. Efforts were made by all involved to ready the helicopters for flight and prepare equipment and supplies for the glaciology field teams. However unfortunately, the weather closed in before flying could start and consequently, both aircraft had to be grounded until the forecast improved. All onboard the ship had their fingers crossed for better weather soon.

Members of the biology team and oceanographic scientists instead busied themselves with the deployment and sampling of the CTD (a device which profiles the conductivity, temperature and depth at several intervals throughout the water column and which collects water samples that will be filtered and analyzed for phytoplankton, productivity and nutrients) at the head of Flandres Bay. We hope to deploy this device multiple times whilst in the bay, and will use data collected from each cast to build a comprehensive picture of what the water column looks like oceanographically and biologically.

Work on and the processing of the whale bone lander, recovered on 8th January off Vega Island was also concluded today. This was a relief for us and for the majority of the people onboard as whale bones are notoriously foul smelling (they produce a rotten egg smell common in anoxic marine environments and processes of decay), and this meant the bones could be packaged up and stored frozen before being deployed again later in our cruise schedule. Several species of worm, including the bone eating worm Osedax sp, were identified on several of the whale vertebrae. Further work will be undertaken on these specimens once we return to the lab in Hawaii, including morphological and molecular taxonomy to evaluate the evolutionary relationships of these worms.

12 January - As the sun rose on the morning of the 12th we continued our journey into open ocean, out of and away from the fast ice that had hampered our progress on the east side of the Peninsula, and bound for the west. From here, the two helicopters we have onboard will transport teams of glaciologists to sites on the Peninsula, where rock geology will be described, ice characteristics measured and the installation of field stations will occur, allowing for long term monitoring of glacial features.

As one of few people who have been lucky enough to visit Antarctica and spend time here working, I (Laura) can honestly say you never tire of the sights and sounds this incredible landscape has to offer. Our journey to the west side of the Peninsula was no exception. I am glad to say our passage was both smooth (for those prone to seasickness amongst us) and idyllic, and provided yet another backdrop of beautiful scenery, during which we were treated to sights of snow-capped mountains, blue open-ocean and floating masses of ice. We made steady progress over the morning passing through the Antarctic Sound, along the coast, and down through the Bransfield Strait into the Gerlache Strait. This area is also renowned for whale-spotting and sure enough several sightings of both Minke whale and Humpback whale were made today close to the ship. These majestic animals are common in these waters, transiting, feeding and using the area as a mating ground. All aboard the ship were happy and excited to welcome our new visitors and were equally anxious for them to stay around long enough to make the most of an amazing photo opportunity.

This side of the Peninsula is characterized by an array of glacial fjord systems and it is from these sheltered inlets that we intend to monitor the weather and co-ordinate helicopter missions when conditions are suitable for flying. Glacial fjords are unique environments influenced greatly by processes of sedimentation, water circulation and glacier retreat which
vary along the length of the fjord system. Consequently, the marine animals living on the sea floor of these areas are of biological interest to scientists. Therefore, in an effort to make the most of our new location and take advantage of a unique opportunity to sample the animals in these fjordic systems the biology team intend to photograph, survey and document
the animals living on the seabed. This will be done using an underwater ‘yoyo’ camera system- a camera which is lowered to the seafloor, and allowed to contact the seabed at which point a contact switch is triggered and a picture is taken. The camera is then brought off the sea bed a couple of meters, whilst the ship moves slowly a long a transect, and lowered again in a ‘yoyo’ like motion until a series of pictures are taken. We will also use a remote operated vehicle (ROV)- a robot on a cable which is piloted by an operator onboard the ship and can be flown over large areas of the seabed, photographing and collecting samples. Fellow collaborators from Ghent University, Belgium are the contingent aboard the ship responsible for the maintenance and operation of the ROV- otherwise affectionately known as ‘Suzee’. Everyone is excited to see Suzee do her first dive into the ocean. Many weird and wonderful creatures can be caught on camera by these devices and certainly on first time viewing you could be forgiven for believing they were pictures from the moon!

Ice Bound and Solid Phase Oceanography

11 January – After the excitement of recovering the whale-bone lander, we headed south around the east side of James Clark Ross Island, aiming for the Larsen B area. As we processed our bone samples, we entered the pack ice, pushing aside larger flows and crushing smaller ones. “Pack ice” is sea ice that has broken into floes of various sizes ranging from pool tables to football fields. Interspersed within the pack ice are tabular bergs that have broken off an ice shelf formed by massive glaciers entering the ocean. An icebreaker does not simply slice or slip it way through the ice; it plows and cracks its way forward, in the process shaking listing, rumbling, and growling. The cacophony and vibrations affect every space on our 307 foot ship (bunks included); the sound is load enough to prevent all conversation on the main deck forward of amidships. This includes the mess, where communication during meals is restricted to yelling.

After eight hours of breaking through pack ice, we had made only 20 miles and it became clear that 4-5 days would be required to reach our first destination, Robertson Island, on the edge of Larsen B. We thus decided to head back north around Ross Island and try the western passage, where fast ice (unbroken ice frozen this last winter) was still
in place. We hoped that this would be thinner (less than 2 m thick) and more brittle, allowing the N.B. Palmer to crack through. By the next morning (10 Jan), we plowed into fast ice stretching to the horizon, at first making five knots through a frozen meter white. Then our ship abruptly listed to starboard and ground to a halt; we were stopped by the ice! Our intrepid vessel backed up and then rammed the ice at 7 knots, allowing us to progress for a few more miles before tilting to a halt. The sensation was very much like a sleigh ride over icy snow into a deep snow drift. The ship backed up and tried another route through the fast ice but we still ground to a halt after a couple of miles. Even thought the ice appeared to be only 1 m thick and our vessel Palmer is rated to break 2-m of ice, we were stuck – no more forward progress was possible. Visions of Shackelton on the Endurance danced in our heads. By this time, it was 8 pm on 10 Jan, so we decided to take a rest for the night, and deploy the helicopters for ice reconnoiter and our first rock sampling on the morrow.

The helmsman's view from the ship's bridge as the N.B. Palmer pushes into the fast ice west of Ross Island. It is almost like moving through an Iowa cornfield in cold, snowy winter!

The morning of 11 Jan revealed a glistening white seascape, 2 successful helicopter operations and our fist oceanographic sampling. While the helos flew south and west, the oceanographers“walked on water,” conducting solid-phase oceanography. The ship lowered its gangplank onto the ice, allowing a party of eight to stroll several hundred meters from the ship to collect ice cores and associated ice algae. Ice coring uses tools developed in the 1800’s powered by elbow grease. We collected three cores of10–cm in diameter to measure ice thickness, temperature, and to recover ice algae (diatoms that thrive in the sea ice matrix) for a variety of analyses. The ice crumbled as it fell out of the core tubes; it was “rotten,” i.e., riddled with melt pockets, through most of its 100 cm thickness. this explained why the N.B. Palmer could not break through; the ice crumbled and piled up in front of the vessel, rather than cracking and letting the ship pass through. Bad news for our “icebreaker” because it is not designed to be an “ice dozer”.

One of our two helicopters lands on the N.B. Palmer after the first successful helo operation from the ship during our cruise.

Craig uses state-of-the-art technology (a Kovacs Ice Corer) to take an ocean water sample (we call this "solid-phase oceanography"). The party in the background is collecting additional ice cores, measuring the sea-ice temperature, and planning a snowball fight.

After a few hours the helicopters returned with further bad news; rotten fast ice and pack ice continued for the 80 miles into our study area with no open water channels (or “leads”) for the ship to pass through. After much deliberation, the scientific party and ship’s captain decided to abandon the icebreaking for now, and head around to the west side of the Antarctic Peninsula to conduct our helicopter installations of ice and geological stations on glaciers and land. The Antarctic Peninsula is so narrow that our helicopters can fly the 20-40 miles from the west side over the top of the Bruce Plateau to Larsen B, given clear flying conditions to 6000 feet. The evening of 11 Jan found us retracing our course through the fast ice, pushing through our day-old “wake” at 7 knots. All aboard the ship were disappointed by this set back, but hope that we will be able to return soon, once the ice has melted or blown out along the east side of the Antarctic peninsula. It is a bit ironic that our project to study climate warming in the Larsen B area is being held back by an unusually later summer breakout of sea ice!

Retracing our "steps" out of the fast ice in the Gustav Channel. Our course is not difficult to follow!

Arriving in Antarctica

10 January – *Antarctic Sound and Whale Bone Lander Recovery.* We awoke on the morning of 9 Jan to sunlight glinting off nearby icebergs and distant glaciers as we passed through the Antarctic Sound. In these protected waters, the ocean was smooth and we made excellent time through the extraordinary scenery of the Antarctic Peninsula. By 6 in the evening (1800 hrs) we were off Vega Island in the Weddell Sea, in position to recover a free-vehicle whale-bone experiment placed on the seafloor 10 months earlier. The “bone lander” consists of specialized animals that colonize whale bones. The lander is dropped to the seafloor with flotation, a lead ballast weight, and an acoustic release holding the weight; at the end of an experiment, the acoustic release drops the weight following an acoustic signal from the research vessel, rising to the ocean’s surface with whale bones for recovery. Such landers are generally reliable but certainly not failsafe – they fail to surface about 5-10% of the time, often for no obvious reason. Thus, recalling a lander always is filled with suspense, especially if your scientific research (i.e., job) depends on it. This bone lander gave us plenty of suspense, remaining on the seafloor for an hour after it was recalled. Finally it surfaced, apparently having been fouled on a glacial boulder until the bottom current shifted directions. To our delight, the recovered whale bones were covered with a special fauna --- hundreds of bone eating worms called Osedax (picture 10) that especially like whale bones, mats of sulfur bacteria, and thousands of segmented (poychaete) worms in the family Dorvilleidae, which contains a remarkable diversity species living on whale bones throughout the oceans. Our small seafloor ecology group (Laura Grange, David Honig and Craig Smith) spent 2.5 days (broken by 6 hours sleep) painstakingly picking the animals off the whale bones, preserving some for DNA analyses, some for food web studies using stable isotopes, and some for biodiversity studies using classical taxonomy (i.e., based or animal “shape” or morphology). Although exhausted by the end of our bone-processing ordeal, we were in excellent spirits. It is clear that we have new species of whale-bone animals, and that we will fill in an important gap in the biogeography and feeding ecology the global “whale-fall fauna,” helping the elucidate the effects of whales, and the impacts of whaling, on marine biodiversity around Antarctica. By the time we had finished our whale-bone tasks, we were stuck in the sea ice, but that is a story yet to come.

Rough Seas!

8 Jan 2010 – *“We’re crossing the Drake!”* This phrase has filled sailors and Antarctic explorers with trepidation for centuries. Why? Because the Drake Passage is considered the roughest water body in the world. It lies between Cape Horn and the tip of the Antarctic Peninsula -- a 480 mile channel concentrating the storms and currents circling the globe in the Southern Ocean. Like any body of water, it is not stormy all the time; storm systems pass through at 5 to 10 day intervals. My 9 previous crossings of the Drake have been mostly pleasant with the ship surfing large swells amid black browed albatross who skim the waves for without flapping a wing. This crossing also began smoothly with a
pleasant sunset and modest seas in the evening of 5 Jan; however, things changed quickly. By the wee hours of 6 Jan the wind howled from the northwest even though no storm had been forecasted. For twelve hours we had sustained winds of 55 knots, with gusts of 96+ (well above hurricane force). The seas reached forty feet, washing over the back deck and making our heavily loaded ship roll like a carnival ride. Most of the glaciologists and land geologists suffered from “mal mar” and spent the day in horizontal in their bunks or watching movies in the lounge. A few hardy oceanographers and the ship’s crew populated the labs and mess deck, but the weather was so rough that even the galley (the ship’s kitchen) curtailed operations, serving cold cuts for dinner. Captain Joe Borowski altered course and held a weather pattern for 18 hours, heading theshp diagonally into the seas to ease the motion, but taking us off course. Fortunately, by the late evening of 6 Jan, the wind and seas had abated and we resumed our heading (albeit a bit bumpily) for the tip of the Antarctic Peninsula. Our horizontal shipmates reappeared the next morning, looking very releaved that the final three days of the crossing were relatively smooth, allowing us to rounding the tip of King George Island in good time. The lesson of this crossing was clear: never take the Drake lightly -- howling gales and mountainous seas can come seemingly from nowhere, making life miserable for seafaring souls!

Beginning to cross the Drake passage

5 Jan 2010 – Our passage past Tierra del Fuego was smooth with following
seas, and we just now have entered the Drake Passage. Of course, the wind immediately switched to our beam (coming from the side of the ship) so we are rocking much more. Because working on the deck of a ship can be dangerous, especially in Antarctica, we have spent the day in numerous safety briefings. These included instruction in rapid donning of a survival suit to keep us alive in frigid Antarctic waters for 12 hours if the ship sinks. These look and feel like Gumbie suits and make you break into a heavy sweat within 30 seconds (unless of course you are immersed in icy water). We also learned how to work on deck, roping ourselves to the ship when it gets rough, and warning our companions if we see a big wave coming. This expedition will also include helicopter operations to fly glaciologists ashore to sample ice and measure to flow of glaciers into the ocean; this too required a long safety briefing (in addition to the 2-day safety course we had in June!). Now it is 10 pm (but still light because we are so far south) -- time to relax a bit, reading a book, watching a movie video, or maybe even writing a blog!

Getting ready

4 Jan 2010 – We have spent the last 6 days at the dockside in Punta
Arenas, living aboard our home for the next 60 days, the Research Vessel
Ice Breaker Nathanial B. Palmer. We were scheduled to head
south from Punta Arenas on 2 Jan, but have been frustratingly delayed by the late arrival of equipment and supplies from the USA (held up in
customs in Santiago), and high winds (hurricane force gusts up to 70
knots!) which prevented us from using the ship’s crane to load our gear
onto the vessel. This did allow us to see a bit more of Punta Arenas,
which still has the feel of a frontier town near the end of the world. This
is the port from which Shackleton sailed on a tug boat to rescue his men
from Elephant Island nearly 100 years ago; some of the windy streets,
Victorian buildings, and bars of Punta Arenas have changed little since
the “heroic era” of Antarctica work. You can almost hear Shackleton
challenging the local sea captains to sail him back to Antarctica to rescue
his men.

According to seafaring tradition, sailors heading south from Punta Arenas
to Antarctica must rub the toe of the bronze Tierra del Fuegan in the
central square of Punta Arenas to assure safe transit across
the Drake Passage. Because the Drake is known as the roughest body or
water in the world, we made sure to rub the toe on the day of our departure. So far it is has worked because we are sailing through the
Strait Magellan under a clear sky with a scenic sunset. We
will entire the Atlantic Ocean in about 12 hours, then turn south along the
coast of Tierra del Fuego for another 12 hours before actually entering the

Arriving in Chile

30 Dec 2009 - After two years of preparation for our expedition to the
Weddell Sea, we finally arrived in Punta Arenas, Chile, the jump-off point
for most research cruises to west Antarctica. “We” are Laura Grange
and Craig Smith, the University of Hawaii contingent for the LARISSA
project, which includes 27 other scientists . The trip from Hawaii was
arduous: we departed Honolulu at 8 am on Dec 27 and arrived in Punta
Arenas at 10 pm on Dec 29 after 25 hours in the airline seats – yikes! 
The people of Punta Arenas are extremely friendly and all our baggage and
gear arrived with us, so we are in good spirits. Today we were issued the
clothing we will wear in Antarctica. Is called “Extreme Cold Weather”
gear to keep us warm while “on the ice” (i.e., working in Antarctica). 
Because temperatures plus wind chill may drop to -40 F, our Antarctic
attire is a bit different from our Hawaiian wardrobe: it includes a giant
red down parka, multiple sets of thermal underwear and insulated socks,
waterproof pants, windproof parka, balaklava (the head cover bank robbers
 wear, but in thick wool), a neck gator, 8 set so thermal gloves, 2 pairs of
mittens, wind goggles, three sets of insulated boots, etc. Each person’s
bag of ECW clothing weighs about 40 pounds and is a pain to lug onto the
 ship. Nonetheless, and we are VERY glad to have it.
