Fleet Ops hard at work repairing airfield, pier at McMurdo
June 23, 2014
As midwinter approaches, May stretched out in a seemingly endless string of days here at McMurdo Station . Peppered with only a few mild storms, not even the weather could do much to alleviate the tedium of the now fully dark days of winter. Within the repetitiveness of those dark days, however, there was still a lot being accomplished on station.
Fleet Operations completed repairs of the Pegasus Airfield ice runway. The runway had been severely damaged by elevated summer temperatures and extreme thawing, leaving cavernous melt pools and uneven landing surfaces. [See previous article — No fly zone: Melt issues at airfield delay wheeled aircraft, shift airlift burden to LC-130s.]
Work has been ongoing throughout the winter to return it to mission-ready status. As of the middle of the month, all 10,000 feet of runway, along with the east ramp, had been smoothed, compacted and certified.It is now ready to receive flights at Winfly, the short interim season that brings in more staff to prepare for the influx of the summer science season. Winfly, short for “winter fly-in,” begins in mid-August this year.
The runway complete, the Fleet Ops department immediately moved on to its next critical mission of the winter: building a new ice pier for summer maritime operations. The pier, which is constructed of floating layers of ice strengthened with cables, is used as the transitional platform to move people and cargo from the resupply vessels to land.
It normally sits nestled in the calmer waters of Winter Quarters Bay, attached to land by a metal bridge large enough for cargo trucks to pass over. A combination of warm temperatures and southerly winds caused large portions of the sea ice to break out of McMurdo Sound during the 2013-2014 summer season, leaving vast amounts of open water. Late season storms pushed the pier toward land and caused it to erode and break apart. [See previous article — Harsh continent: Storms and waves batter McMurdo Station due to absence of sea ice.]

The ice pier deteriorates during a storm at McMurdo Station while the cargo vessel was docked earlier this year.
Construction of the pier takes place midwinter when the temperatures are coldest. Seawater is pumped to the surface and frozen in layers until the pier reaches a thickness of approximately 10 feet. This will keep it solidly in place as the ice around it melts next summer.
All work and no play makes for a dull winterover. So, to break up the monotony of the long month, residents organized an evening of wine tasting. Unearthing new wines from McMurdo’s beverage stockroom and the storehouse at Scott Base , the New Zealand base located approximately three miles away, revelers were treated to tasting samples as some of McMurdo’s talented musicians played live music in the background.
McMurdo residents ushered out the month of May paying tribute to our nation’s fallen soldiers with a Memorial Day celebration. The station’s main hallway became the center for Memorial Day facts and history, along with photos recognizing the service of residents and their families, both past and present.
At 10 a.m. on Memorial Day, a working holiday here on station, people gathered to lower the U.S. flag that flies year-round over the station as Taps was played. After a few words from station management, the ceremony moved indoors for cake and coffee. While light in the pomp and circumstance, Memorial Day is still a sacred day in a place that was built on the hard work and dedication of our military men and women.
Winter crew addresses Pegasus Airfield damage from summer

April was a fairly quiet month at McMurdo Station , as the sun slowly settled below the horizon, and residents slipped fully into the winter tasks that will keep us busy until next summer.
The last sunset of the season took place on April 24 .The sun rose at 12:06 pm and then set for the final time at 1:35 pm. This was the last time we’ll see the sun until it rises again on Aug. 19.
While the weather on the 24th was cloudy and windy, a group of about 70 winter-overs was able to make a trip out to the McMurdo Ice Shelf the day before to say a final farewell to summer light. Piled into Ivan the Terrabus, a large people-transporter with gigantic tires for travelling over ice and snow, residents were bussed out to the Pegasus Airfield for a lunchtime getaway.
Due to McMurdo’s location, set at sea level surrounded by hills, the ice shelf was the only vantage point for seeing the sun during its last month in the sky. Before returning to station, these sun worshipers also made a stop to visit the remains of the C-121 “Pegasus” aircraft, which crashed there in 1970. While there were no injuries, the plane was lost; its remains are now partially entombed in snow and ice. It serves as the namesake for the current airfield used each summer.
To make up for the loss of a daily dose of vitamin D, the McMurdo light room was opened to the public this month as well. Set up in an unused dorm room in Building 155, which also houses the cafeteria and the store, the light room is a peaceful setting of couches and chairs that is equipped with light fixtures with full spectrum bulbs. This serves as an alternative for the natural sunlight that will be missing from our lives over the next four months.
A volunteer delegation of Americans also made the trip over the hill to the New Zealand base on April 25 to participate in their ANZAC day celebration. The New Zealand Memorial Day honors Kiwi and Australian soldiers lost in battle. Faced with biting wind chills, the ceremony, which included bugling and bagpipes, took place indoors, with a few Scott Base residents having to venture outside to lower the flag. Working closely year-round with our counterparts at Scott Base, we were honored to offer our respects on this occasion.
The biggest hustle and bustle of April took place far from station back at Pegasus Airfield, which was severely damaged during the austral summer from a mix of warm temperatures, intense solar radiation and dirt blown over from Black Island.
Since then, the Fleet Operations department has been working tirelessly, as long as weather conditions allow, to bring the air strip, as well as the area surrounding the support buildings, back up to operational specifications. Working against the setting sun and the loss of good working light, the small fleet of heavy equipment operators has made daily trips along the 13-mile snow road to fill in deep sink holes caused by melt pools and to smooth and compact the surface of the ice so it is ready to receive the next flights, scheduled for mid-August.
By the end of the April the finish line was in sight, and they hope to complete this arduous project by the end of May.
Winter begins with a flurry of safety preparations
April 24, 2014
In terms of daily station operations, the month of March at McMurdo Station lived up to the old adage “in like a lion, out like a lamb.” It began with a flurry of activity but ended at a markedly slower pace, as personnel settled into winter routines.
With the station almost to its winter population size at the start of the month, departments had to work double duty to cover final flight operations. With shifting weather and flight crew availability, U.S. Antarctic Program support personnel on multiple continents scrambled to schedule and carry out the last few flights to shuttle the remaining summer staff off station.
Thanks to the flexibility and hard work from many different work centers, the final flight of the summer season took off on March 9, leaving behind a winter population of 142 people to carry on station operations until the next scheduled flight, likely in late August.

There was still plenty to keep people busy, as the winter staff prepared and organized for the onset of the winter season. On March 15, everyone on station turned out for what is affectionately referred to as “daisy picking,” an all-station outdoor clean-up that gathers up loose items around town, as well as secures and organizes outside storage areas in preparation for winter storms. The effort also ensures that all travel paths are clear and defined, and secures items that could blow away and cause damage to people or property during the dark days of winter.
Further safety measures were put in place as everyone completed the mandatory Winter Survival Training and Outdoor Safety Lecture courses. These programs are designed to define and highlight the hazards of working and playing outside in Antarctica.
The courses teach skills such as recognizing signs of hypothermia; using radio communications for keeping in touch with the firehouse during work or recreational travel; setting up tents and building wind berms out of snow; and using the contents of survival bags that accompany anyone travelling away from station for work purposes.
With safety always on the forefront of all station activity, dorm evacuations and fire drills were held to familiarize all residents with muster points and accountability plans in case of a fire emergency.
The medical team also issued a skills assessment survey to gauge various skill sets in case of a mass casualty incident (MCI). With a skeleton crew on station over the winter, any medical emergency with multiple injuries could overwhelm the medical and firehouse staff, requiring the aid of trained volunteers to complete a range of tasks, from transportation and stretcher bearers to assisting with patient first aid and care.

An auxiliary medical team, complete with recorders to track patient symptoms and treatment, was selected based on people’s prior education and skills. Group training sessions began to familiarize team members with the medical facility, the MCI plan and each person’s particular role in the event of an emergency.
Even with all the training and preparation, life has begun to slow down into a steady winter rhythm. Buildings that have been vacated by summer staff have gone cold and been winterized; unused equipment has been shut down and gone silent; and the once bustling roads on station now harbor only the occasional piece of large equipment.
With days getting steadily shorter and the darkness creeping in, the winter staff can now get down to the business of maintaining the station through the long winter months, as we prepare for another busy summer science season that will be here before we know it.
February storm causes operational scramble at McMurdo Station
March 21, 2014
February was a hectic month at McMurdo Station , as personnel made the final push to complete preparations for winter.
Following the arrival of the U.S. Coast Guard cutter Polar Star and the refueling vessel, Maersk Peary, the cargo vessel Maersk Illinois pulled into Winter Quarters Bay during the first week of February to deliver a year’s worth of supplies.
Battling poor weather conditions and a deteriorating ice pier that had already been weakened by erosion caused by extreme wave action, personnel scrambled to unload the ship during 24-hour offload operations.

A storm in February lashes the cargo ship MAERSK ILLINOIS while it is tied up at the McMurdo Station ice pier, which eventually broke into a half-dozen pieces due to the increased wave action.
While all the cargo was successfully removed from the ship, personnel were unable to load more than 100 shipping containers that had been slated to leave with the ship, as a strong wind storm moved in and halted all operations, eventually causing the ice pier to break apart. [See related article — Harsh continent: Storms and waves batter McMurdo Station due to absence of sea ice.]
The shipping containers held everything from station waste to scientific samples and had to be dealt with accordingly after the Illinois managed to depart station on Feb. 9. That left station leadership scrambling to find room in the dwindling flight schedule to deliver important scientific samples to their destination by air, while the rest of the containers were stored to wait until next year’s vessel operations.
The same storm wreaking havoc on vessel offload also caused a brief moment of uneasiness when it was discovered that the high wave action was causing the ground beneath the seawater intake pumps at the water intake jetty to deteriorate.

These pumps provide all the seawater that is used to make the station’s water supply by filtering it using reverse osmosis. Station personnel leapt into action to set up a temporary intake line so that heavy equipment could be brought in to bolster the jetty. Quick thinking and hard work paid off, and the permanent pumps were back in operation within a week.
While folks dealt with these issues on the water, others were fighting a never-ending battle with conditions at the Pegasus Airfield ice runway. Personnel worked 24-hour shifts to try to maintain the ice runway, shuttle summer personnel off the ice and complete South Pole Station fueling operations before Feb. 14 when the Pole winter isolation began.
Though weather conditions made it difficult, the long hours paid off, with the successful end to the season. South Pole Station was fully fueled for the winter, and flight operations managed to continue through the end of the month.
Those final flights of February carried in most of the remaining winter-overs, even as the station population shrank dramatically with each departing flight. Starting the month with almost 1,000 people, there were a scant 200 as February came to a close.
The last flight of the 2013-14 season at McMurdo was on March 9, leaving a population of 142 people for the coming winter. Hopefully, Mother Nature is a little kinder than she was over the summer.
Visitors aplenty in January, from tourists to journalists to wildlife
February 28, 2014
January was a busy month at McMurdo Station , as everyone worked full steam to complete projects, wrap up science and begin preparations for the winter season.
Tim Bisbee, the new winter site manager for McMurdo Station, arrived in January. As a new addition to the McMurdo team, he will spend the month or so leading up to the winter familiarizing himself with the station and turning over operations from the current summer management.

Science field camp activity reached a peak early in the month with 126 people working at 21 camps across the continent. The science traverse across the Ross Ice Shelf to deliver a drill for the Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) project reached camp on Jan. 9. The team successfully drilled four holes into the ice to place a geophysical instrument near subglacial Lake Whillans to learn more about its morphology.
The McMurdo Dry Valleys were also abuzz with activity, with camp staff supporting multiple science groups, and many others working at self-supported camps. Some McMurdo residents experienced the Dry Valleys on working trips to provide extra hands for digging out a fuel cache that had drifted in at Lake Bonney.
LC-130 flights increased in January as well, as the New York Air National Guard made a push to complete all scheduled flights. The LC-130s are used to move fuel and cargo to the South Pole Station and to some of the larger field camps.
Earlier delays due to weather and mechanical issues meant flight operations were increased to a frenzied 24-hour pace to make sure that all operations, particularly refueling South Pole Station, were complete before the Air Guard crews returned home. The flight crews also continued to provide airlift between McMurdo and Christchurch, New Zealand.
The skies weren’t the only busy thoroughfare in January.
The U.S. Coast Guard cutter Polar Star arrived at the ice pier on Jan 16 to begin the parade of ships into McMurdo Sound and Winter Quarters Bay. The Polar Star’s primary mission is to break the ice channel from the ice edge, approximately nine miles or so from station when the cutter arrived, to the harbor where the refueling vessel and the resupply vessel dock to unload their cargo.

Favorable, strong winds assisted in the ice movement, and McMurdo Sound quickly cleared of all ice, leaving in its wake lapping waves and increased wildlife activity. Minke and killer whale sightings became a frequent event from nearly every work center window.
The open water also cleared the way for a brief window of opportunity for cruise ships to visit station, and volunteer tour guides hosted approximately 360 visitors from the five Antarctic pleasure ships that visited the harbor.
Finally, McMurdo also played host to a visiting reporter, as David Bjerklie, a science journalist for Time Magazine’s Time for Kids publication, spent 10 days visiting. Time for Kids is a weekly classroom news magazine, and this month it featured National Science Foundation -supported science projects happening in and around McMurdo.

McMurdo Station stays on the move in December
January 17, 2014
As the last of the summer stragglers trickled in to fill spots left open after October’s partial government shutdown, operations in McMurdo Station ramped up in December, with the population peaking at 765 people.
December was a busy month for cross-continent travel, with multiple traverse teams crossing the ice. The South Pole Traverse (SPoT), a train of tractors that pull sleds carrying fuel bladders, had two caravans in operation across a thousand miles of Antarctica.
SPoT1 returned to station on Dec. 29, after delivering about 96,000 gallons of fuel to South Pole Station earlier in the month. Not far behind, SPoT2 began its return trip to McMurdo after Christmas, having arrived at the Pole on Dec. 16. Spot2 delivered nearly 124,000 gallons of fuel in bladders, which was then transferred into the long-term storage tanks at the South Pole.

The first South Pole Traverse makes its way down the Leverett Glacier in December.
The 220,000 gallons of fuel delivered by these two traverses was the equivalent of about 60 LC-130 fuel flights, which until the last few years was the only way to deliver fuel to the station.
A different sort of tractor train left McMurdo Station on New Year’s Eve. The “light” traverse team left station en route to a field camp at the edge of the Transantarctic Mountains, approximately 650 miles south of McMurdo Station, in support of the Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) project.
Last year, researchers with WISSARD drilled into a subglacial lake through about a half-mile of ice where they collected water and other samples, discovering life in that extreme environment. This year’s study will focus on geophysics experiments that will image the lake, including drilling holes in the ice sheet and deploying instruments inside. The traverse carries all the drilling supplies that will be needed to complete this year’s activities.
Folks work six days a week, and with a round-the-clock operation, everyone takes advantage of recreation when possible. There are daily and weekly options for activities – from yoga to basketball – but some of the most notable were those focused on outdoor adventures.
Taking advantage of the good weather, volunteer tour guides offered almost daily trips to traverse the pressure ridges along the ice shelf-sea ice transition. These pressure ridges, located near New Zealand’s Scott Base just a couple miles from McMurdo, are formed as tidal movement in the water below the ice causes cracks, which are then pushed against one another and forced upwards along the fault lines.

The holiday season was a festive time on station, with many people contributing to a feeling of holiday cheer despite being separated from family and friends. Kitchen staff and volunteers worked hard to decorate the dining area with garland, snowflakes and other handmade crafts to bring a touch of home to this faraway place.
For the more musically inclined, a Christmas choir was convened, with rehearsals over the weeks leading up to Christmas Eve, when a recital of classic tunes was held to kick off the annual Christmas party held at the Vehicle Maintenance Facility. Santa Claus even made a special appearance for photos and holiday greetings.
On Christmas morning, there was a race up Observation Hill, the highest local peak, looming 750 feet over station, for those inclined to make the grueling trek. Male winner Trevor Layman reached the peak in 7:01 with female winner Sarah Kernasovskiy not far behind at 9:25.
One of the highlights each Christmas is the lavish holiday dinner, and this year was no different. Beginning preparations two weeks prior to the big day, the kitchen staff, with the help of many eager volunteers, prepared five full Christmas dinners. This encompassed multiple seatings throughout the day and night to cover all shift workers.
According to kitchen steward Shannon Keller, McMurdo residents ate 600 pounds of prime rib and 400 pounds of lobster tail, 75 pounds of broccoli and 440 pounds of potatoes – and that doesn’t take into account the 160 pounds of potatoes used to make gnocchi. For those with a sweet tooth, 135 assorted cakes, tarts, torts and Bundt cakes were consumed, along with 800 cookies and more than 1,000 hand-dipped truffles. Topping off this massive feast was 140 pounds of fudge and 20 gallons of egg nog.

The 25th anniversary of the music concert known as Icestock took place on Dec. 31.
That’s enough to kick-start anyone’s New Year’s resolutions!
Speaking of New Year’s: Holiday festivities wrapped up with the 25th annual Icestock performance on Dec. 31. This outdoor music festival featured 12 bands playing more than seven hours of music. As the musicians rocked in the New Year, others battled it out to reign champion in a chili cook-off competition. Beautiful sunny skies and calm weather made this year’s event all the merrier as McMurdo residents rung in 2014.
Although summer activities are still ongoing, we are already looking ahead to the hand off of the station between the summer and winter crews.
In December, the winter-over Search and Rescue Team (SAR) was selected from a pool of applicants, and the new team began training.
The SAR team is responsible for rescue activities in the case of missing or injured personnel, both on the job and during recreational travel. They also work as escorts for personnel movement during severe storms. They train weekly throughout the year and work jointly with the New Zealand SAR team to provide a safety net for all Ross Island personnel over the winter.
Training began with sea ice profiling, which taught team members how to safely and accurately profile ice depth and crack safety when travelling over the sea ice. This will be useful in rescue operations, and will also be utilized at the end of the winter when setting travel routes to scientific sites such as Cape Royds and Cape Evans.
