Palmer Station enjoys brief lull during Midwinter before science returns
July 18, 2014
Palmer Station caught its collective breath in June. A sense of calmness settled over the station, as the winterovers settled into their winter routines, having the station to themselves, with no port calls for the month.
Air and sea temperatures cooled, and a low-pressure system hung around the area for 10 days. The sea began to freeze, first taking hold in smaller areas like Hero Inlet, and eventually extending throughout Arthur Harbor and beyond. The increasingly solid sea ice tamped down the energy of the sea.
The fur and elephant seals that remained in the area kept pace with the solidifying ice, moving from their favorite haunts on Bonaparte Point to areas closer to the ice edge. Due to both sea ice conditions and increasingly short daylight hours, boating activities ceased and outdoor recreational activities were limited to the lunch hour, or were performed sporting headlamps.
In the six weeks between research cruises, Palmer residents had a chance to get to know each other even better in this small community. Monthly training sessions for the Search and Rescue and Fire teams lent opportunities to solidify teamwork skills.
The Palmer Iron Chef competition showcased the culinary talents of four chefs who labored for one rushed hour to produce at least two dishes that incorporated a secret ingredient (in this case, chilies). The rest of the community eagerly participated as enthusiastic judges.
On one calm winter Sunday, some top ropes were placed on the receding glacier face behind the station, allowing us to test our ice-climbing skills. And these were just a taste of some of the interesting and fun times we had together.
Midwinter Day, the traditional Antarctic holiday that blends the milestones of mid-season and Winter Solstice, was celebrated June 20. The dining room was transformed with one long banquet table. Decorating the walls were the flags of the 12 original Antarctic Treaty nations, as well as those flags that uniquely identified members of the community.
With the elegant tones of classical violin, the evening commenced with a cocktail hour. Guests wandered into a surprising assortment of appetizers that even included some fresh apple and carrot, some 11 weeks after the last arrival of freshies.
The chef created an elaborate multiple-course meal, served family-style. Several types of sushi were artistically presented to the table, with a palate cleanser of wasabi ice cream. Main course items of salmon, asparagus, and potatoes were delivered to the table, and as the pièce de résistance, the leg of guanaco was carved table-side by chef Mike.
Dinner was completed by an amazing assortment of elaborately crafted dessert offerings that pleased every palate. Several toasts were raised, to the continuation of a successful winter season together, to the various sacrifices made to take part in this Palmer winter season, and to the fantastic efforts of the chef.
Just as we waited for the turning of the sun and the return of longer days, we started to expect the return of the research vessel Laurence M. Gould at the end of the month. Its arrival on June 29 doubled the number of personnel on station, bringing in two late-winter science groups who will remain until the middle of August.
Palmer Station population drops to 19 for remainder of winter
June 23, 2014
Weather is the master over most human activity in Antarctica. In May, Palmer Station was given a reprieve from typical May conditions.
Mild temperatures were experienced throughout the month, averaging 0.9 degrees Celsius. There was little snowfall, and no sea ice formed during May. With the warmth came gusty winds of the type that can throw you off your feet, whip open doors, or send untethered objects into the air.
For 10 days the winds gusted above 40 knots, reaching a maximum of 60 knots. The boom of the calving glacier was a consistent background sound, as the glacier donated pieces of brash ice to Arthur Harbor. Such was May along the Antarctic Peninsula, the “banana belt” of the continent.
The mild, though windy, conditions allowed the special projects teams to progress toward the completion of their respective tasks: upgraded pier facilities, a wide boat ramp, parking decks for the Zodiacs, and a new antenna tower in the “backyard.”
During the first half of the month, the research vessel Laurence M. Gould departed Palmer Station on two fishing cruises, arriving back with multiple species of Antarctic icefish that were delivered into the aquarium tanks. These are the subjects of further study by two scientists who will reside on station for the remainder of the winter.
Station schedules revolve around the coming and going of the Gould, requiring many hands for line handling during the docking and undocking of the ship, for fish offload after a fishing cruise, and for cargo operations.
As the scientists diligently finished their projects, station personnel prepared for the departure of the Gould on May 15. Leading up to that departure, Palmer Station had several events bringing the entire community together. In addition to the regularly scheduled science lectures, the science community hosted several “show and tell” events to share details of their work.
Many informal gatherings of jamming musicians, contented movie watchers, spirited dancers, competitive Ping-Pong players, and energetic outdoor enthusiasts spontaneously arose to enjoy free time at Palmer Station. To cap off our time together, an all-station talent show was held, highlighting in one evening a surprisingly diverse array of abilities.
With more than half the Palmer population headed back to South America with the Gould, the station diminished from maximum capacity with overflowing numbers berthing on the Gould to 19 winter-overs who will remain for the duration of the winter season.
A mellower winter pace settled onto the station. Everyone had a little more elbow room, spreading out into single rooms. The galley was reconfigured with fewer seats into a homey family room setting. The laboratories were eerily quiet. Activities focused on keeping the station running, as always, and in getting ready for the next southbound cruise at the end of June.
By the end of May, the air and sea temperatures reluctantly began to drop into a more wintery regime.
Palmer Station makes the transition to winter as new personnel arrive
May 23, 2014
April is the beginning of the winter season at Palmer Station . Winter would seem to be the season to rest, to reflect, to slow down and to rejuvenate. Not so this month at Palmer Station.
With the departure of the summer staff in late March, the winter-over crew quickly took over the reins, falling into their professional roles, as well as various community responsibilities. In this small community, each person wears many hats.
Upon arrival to the station, assignments are made for the various teams that keep the station safe and functioning: Ocean Search and Rescue (OSAR), Glacier Search and Rescue (GSAR), line handling for the ships, fire team, and trauma team.
A dozen extra personnel were on station all month working on special projects to maintain and upgrade Palmer facilities. Throughout the month, notable visual progress was made around station on the pier facility, the expansion the boat ramp, erection of antennae, and interior painting.
Mid-month welcomed the return of the research vessel Laurence M. Gould , delivering five winter science groups to Palmer. Schedules revolved around the coming and going of the ship, with four cruises to local fishing grounds in two weeks. Three groups were involved in these cruises, with the objectives of trawling for Antarctic fish and plankton, and grabbing sediment samples.
Meanwhile, the scientists on station raised an antenna that detects waves from lightning worldwide, and worked on equipment that monitors radionuclides from the atmosphere.
Weather-wise Palmer was treated to the entire gamut of conditions. Temperatures fluctuated all month above and below the freezing point, bringing alternating periods of driving rain and accumulating snow, mixed in with beautiful, clear, calm, sunny patches.
Several periods of high winds helped move ice around the area, driving a rather large iceberg into very close vicinity of the pier and the Gould. At one point, all eyes were on the berg as it nudged closer and closer to the Gould on the incoming tide. This, and other, iceberg visitors moved in and out of the area all month.
Nature is telling us that we are in the winter season. Daylight diminishes by about five minutes with each passing day. The local animals are becoming fewer and fewer, abandoning the local area for the winter months. But we humans are slow to get the message, as we toil away, full of energy and activity at the beginning of the winter season at Palmer.
Summer field season at Palmer wraps up – but more science to come in winter
April 24, 2014
It’s a wrap.
Among the groups that departed was the birders, a team that is part of the Palmer Long Term Ecological Research (LTER) program . The group monitors seabirds in the region, including penguins, skuas and petrels. The group reported that for the third year in a row, south polar skuas failed to fledge any chicks within the team’s Shortcut Island study area.

Other scientists who headed north in March included researchers with other components of the Palmer LTER, as well as researchers studying phytoplankton, krill, carbon accumulation in moss, and ground water inputs into the ocean.
It was a busy season, by the numbers, at Palmer Station, with a total of 11 research teams working at Palmer Station at some point during the austral summer months. The station also supported two artists through the National Science Foundation’s Artists and Writers Program .
The last tourist cruise ships also visited in March, along with British ships RRS James Clark Ross and the HMS Protector. Altogether, the station hosted 15 cruise ships, yachts or military vessels over the summer, with personnel making four off-shore visits to larger cruise ships for outreach presentations.
The Gould, of course, was the most frequent visitor, making 11 port calls over the course of the summer. The winter season promises to be no less busy, with five new science groups expected at Palmer Station in April.
A stormy, wet February gave way to a drier but colder March, with the temperature dropping almost a degree lower than last month. The high temperature for March was 42 degrees Fahrenheit, with a low of 25F.
The glacier near Palmer Station continued calving at a steady pace, dumping large amounts of ice into the waters of Arthur Harbor. Ice of land origin, plus swaths of brash ice and occasional bergy bits, were seen on most days. Additionally, a moderate-sized ice berg appeared off the station around mid- month. By the end of March it had broken into three pieces and grounded itself, just south of the station.
Signs of winter appearing at Palmer Station
March 7, 2014
The Palmer Long Term Ecological Research (LTER) cruise came to an end in early February, and the population at Palmer Station started to shrink. February marks the start of a transition from summer science to the winter research season. Shortly, most of the active science groups will make their way north.
For now, though, science is still going strong. Sea ice is no longer an issue as it was earlier this summer for the teams that use Zodiac inflatable boats to access islands or sample the ocean water. The biggest factor hindering off-station research is the wind, as the weather slowly changed over the past month. Days filled with high winds, rain, and even snow are becoming more common each week.
The newborn wildlife has quickly grown before our eyes, and many animals have started to leave the area. The Adélie chicks have lost their downy feathers and now more closely resemble their parents in both size and coloring. Their voices have yet to change, and if not for the white on the underside of their necks, one would be hard-pressed to differentiate them from the adults.
The sheathbills that have nested on station have successfully bred. Chicks now can be seen with the adults walking about station exploring the world outside of the nesting areas. Soon, they too will be soaring in the skies – or at least giving it their best try.
Early in the month, large amounts of krill in the waters around station attracted large numbers of crabeater seals. One small iceberg in the area had 50 different seals sleeping on it. There was so much food that leopard seals were seen napping just feet from the crabeater seals.
The research vessel Laurence M. Gould returned to the Palmer area with a group studying the mosses in the western Antarctic Peninsula. They hope to learn more about the current and historical warming trends in the area. From their research, they’ve found samples of mosses that have started to grow again after being uncovered by the retreating glacier near station.
Also on the Gould were the rest of the team members of a group sampling the ocean and ground, investigating the pathways through which fresh water enters the ocean. They hope their data will provide some clues as to the origin of the fresh water, such as underground streams, surface streams or even as glacial meltwater.
Several ships visited Palmer during February, including a visit from the Aquillies, a ship in the Chilean Navy. Several crewmembers from the Aquilles came ashore for a tour of Palmer. In turn, several Palmer Station residents got a chance to visit the Aquillies.
As February comes to an end, the summer science season gets just a little bit closer to its end. Soon the winter crew will be here on station for turnover, and summer will officially be over.
Palmer LTER project takes center stage in January
February 14, 2014
January marks the start of the New Year, but at Palmer Station , the first month of the year carries additional significance. It is during January that the Palmer Long Term Ecological Research (LTER) cruise takes place.
The LTER cruise is the biggest annual research project that happens at Palmer. Each year the research vessel Laurence M. Gould follows the same route, established during the 1991 inaugural year, for a month. (The grid was expanded farther south several years ago.)

The long-term observations help create a historical picture of part of the Antarctic Peninsula region, which is undergoing rapid environmental changes. Not all samples for LTER are taken from the Gould; some are taken from near Palmer Station by Zodiac. LTER projects range from taking water column samples, launching gliders, dragging nets for krill, to counting seabirds (including penguins), whales and seals.
In addition to the LTER, a number of other science projects are very much active on station this summer. There are a few new groups at Palmer.
One team has set up coastal radar installations to chart ocean currents. This information can be used to learn more about the currents and flow of the ocean around Palmer, but also can be used to see what boating conditions are like far from the station, predict what the sea ice coverage is like, or even predict areas where krill – and their predators – might be located. Test sites have been set up at the station and at two clusters of islands away from Palmer.
The other new research team here this season spends much of its time sampling water, from both the ground and the ocean. The group is hoping to learn more about the path fresh water takes into the sea to determine if it is mainly from glacier melt or from unknown underground rivers and streams. Scientists collect hundreds to thousands of gallons of water, which is run through filters to concentrate the indicators that they are looking to analyze.
With the sea ice now gone, the ocean surrounding Palmer has gone from clear to murky with the phytoplankton bloom. This brings the krill out to feast, and also the top predators that depend on the krill. Sightings of whales, seals and penguins in the area have been increasing. In addition to the common humpback and minke whales, orcas or killer whales have been seen near station.
The number of crabeater seals has also exploded. It has become hard to find any flat ice floes in the area without at least one or two sleeping on it. There have even been reports of leopard seals sharing the same ice floes.
Torgersen Island opened back up in January, enabling visits to the Adélie penguin colonies. The chicks that hatched in December are quickly approaching the same size as their parents.
Sea ice clears out for research to get under way at Palmer Station
January 17, 2014
December was a turning point for many here at Palmer Station . The sea ice that had prevented station science from doing offshore sampling has finally receded, and the end of the month marks the halfway point of the summer field season.
Last month, the ice was thick enough that five people scheduled to head north were left stranded at Palmer after the research vessel Laurence M. Gould failed to reach station after a science cruise.
They didn’t remain stuck for long. On Dec. 5, they were able to board a cruise ship for the ride north. The sea ice prevented the ship’s passengers from visiting the station, but it opened up just enough for those stuck at Palmer to get into a Zodiac and travel through a channel of water opened up by the ship’s bow thrusters.
Researchers could finally work away from station as the ice broke away. In the Palmer boating area, there are a bunch of GPS points where science groups will return to lower instruments into the sea to take samples from the water column.
One team that focuses on seabirds as part of the larger Palmer Long Term Ecological Research (LTER) program was able to get out and count the nesting birds in the area. They’ve found that just about all the penguin chicks on Torgersen Island have hatched and are quickly increasing in size. Many of these penguin chicks are viewable on the Palmer Station penguin webcam that was recently set up and activated.
The Palmer Station footprint changed drastically in December. Gone from the pier area are the numerous shipping containers used for storage. As part of a project to install a boat ramp at Palmer, the containers needed to be relocated to make room for future boat storage. Some of the containers have been moved behind the GWR building, while the containers related to the processing of the hazardous waste on station have been moved up the hill closer to the storage locations of the processed waste.
As part of the boat ramp project, work has also continued to break up many of the large rocks in and around the landing area to facilitate the completion of the ramp at the end of the summer and into the winter. In order to remove the rocks, various methods are being used – expanding grout, rock splitters, and drills. The granite proved too tough to be removed by jackhammer over the winter, but seems to be giving way to the new methods.
Thanks to the many holidays that take place in December, there was quite a bit to celebrate besides the sea ice going away.
Rather than celebrate each holiday individually, special meals where held on the appropriate nights, with a gift swap near the end of the month. The gift swap at Palmer follows the form of a White Elephant or Yankee swap. Each person submits a “present,” and people take turns picking and stealing gifts from one another.
Many of the gifts are handcrafted, and the creativity is often overwhelming. The gifts this year ranged from a guitar built from junk, recycled glass turned into a glass set, cutting boards, a handcrafted knife, and handmade sweets. While it doesn’t replace spending the holidays with friends and family, a Palmer holiday celebration places a close second.
