Flying into Marble Point there’s not much to see from the air. It’s about five buildings, dwarfed by fuel tanks. It’s all tucked away into the loose gravel of a spit of land between the glacier and the sea.
But upon exiting the helicopter, you discover another world. A man waves and shouts hello from across the landing area. Even the fuelie smiles as she drags a hose toward the thirsty vehicle. A woman waits in the warm house, ready with hot chocolate, tea, and coffee.
They are James Raml, Meg Flanagan and Diane Bedell. They are the real Marble Point. McMurdo’s still the big town, but this is civilization, Antarctic style.
Helicopter pilots know Marble Point well. They fly into and out of the Dry Valleys through the area.
The Cape Roberts pilots also stay here, on the west side of McMurdo Sound, to be able to fly the morning shift change even if there’s weather in McMurdo.
Raml describes the place simply. “It’s gas, food, lodging and cargo.”
For four seasons, he’s been the site manager, the telecommunications technician and general handyman. If it’s been built or repaired around Marble Point, he’s worked on it. There’s almost nobody else, and not much in the way of materials.
He took a Wannigan structure when Williams Field got rid of it. It was leaning over and pretty well beaten up.
That was a couple of years ago. Now it’s upright, with a new floor and a new coat of paint on the inside. It sleeps eight and includes a furnace that’s as clean as a new one.
All of that was done with materials left over from other projects, including work done at McMurdo or the South Pole.
There’s always more to do. Among the tasks: Cleaning up the site from decades of messy Antarctic operations, getting cargo ready for transport to the Dry Valleys, getting waste and cargo ready to return to McMurdo, and then–oh yes–the normal stuff to support life.
Even in just a short 10-minute tour of the place, Raml comes up with a list of about a dozen things he intends to work on now or in the future.
“Every year I try to get a few things done,” he said of his “spare-time” projects.
In addition to helping Raml with the cargo and life-supportjobs, Bedell makes sure the guests are at home in their well-maintained surroundings.
“We try to run it basically as a bed and breakfast,” she said.
She makes an excellent quiche, ensures that everyone has more hot drinks than they can
hold, and is the weather observer, medic, and doer of anything Raml doesn’t do–except fuels.
She is very relaxed, though, even with all that on her plate. She’ll sit with you and talk if you’re in the mood, or let you be.
Raml and Bedell make an excellent team. They have anywhere from one to 12 guests on any given night. The camp can sleep 17, and while the table is not quite big enough for everyone all at once, there’s plenty of room for eating in shifts.
The other member of the team is the refueling technician. Fuelies rotate every three weeks, which is a nice break from town, but is no picnic. Helicopters fly 24 hours a day for large portions of the season, and there’s always another one coming in.
It means all three are going all day long, stealing time “off” whenever there’s nobody visiting and no helicopter on the way.
The beautiful setting is just part of the payoff for being the first field camp put in each season, and the last to be pulled out. For all of them, it’s the appreciation on visitors’ faces when they realize this is a special place and that they’re as welcome as can be.

Ambling through Ice Town
Published in the Antarctic Sun
Three miles out onto the sea ice from McMurdo Station, a few small buildings are clustered together in two rows. Radio antennas are perched atop rooftops; vehicles come and go constantly. Bulldozers and graders clear runways, roads, and loading and fueling areas.
It’s sometimes called “Ross Island International Airport,” but more often it’s “the ice runway.”
As the staging area for cargo and passengers coming to and from Antarctica and moving around the continent, the ice runway (and later in the season, Williams Field) is a vital area for successful seasons at McMurdo, South Pole and the field camps.
It’s easy to think an airport is just about pilots and air crews, but there is much more behind the scenes. People who don’t fly at all have key roles to play in the process.

Cold Hard Queries
Published in the Antarctic Sun
In recent days, several people have stopped by the Sun’s office and posed intriguing Antarctic trivia questions. Here are the answers we’ve found:
Is there lightning in Antarctica?
Jeff Prucinsky of Mac Weather reports, “I do not believe that there has ever been a recorded case of lightning in the Antarctic.” The reason is that lightning requires clouds that are tall enough to have large areas of positive and negative charge. Because Antarctica is so flat and white, there is little convective activity, and no chance for clouds to form high enough, Prucinsky said. With no tall clouds, there is no lightning.
How did Amundsen and Scott know when they had reached the South Pole?
Both expeditions used a navigational instrument called a theodolite (the-AHD-oh-lite), which measures the elevation of the sun above the horizon, to map the track of its orbit. From the
path of the sun across the sky, Amundsen’s and Scott’s parties were able to determine their latitude. Longitude was of no concern, since longitude is meaningless at the poles. As well, Scott knew he was at the Pole because he found a Norwegian flag planted there.
Why is a Jamesway called a Jamesway?
This is a tough one. Though we’ve been unable to pin down an answer, we’ve heard several theories, including that the building is named after a person named James Butler Way, or
after a person or corporation called Jamesway. If you can shed additional light on
these ideas, or know of other theories, please contact us at the Sun.

Esprit de ‘core’: Teamwork takes Cape Roberts Project to new depths
Published in the Antarctic Sun
It’s the deepest bedrock hole in Antarctica. When the drilling at Cape Roberts stopped for the season on Thursday the hole was 3,084 feet deep—more than 650 feet farther than the previous record.
The two drillers, Malcolm MacDonald and Frank Tansey, took turns being the most important men in the Cape Roberts Project: the men who made sure the core kept coming up out of the hole and into the hands of climate researchers.
The drillers, though, couldn’t do anything without a lot of help of all kinds. The 40-person support and science team at Cape Roberts works around the clock, which makes for some odd situations.
“It seems a bit strange to see people in here having a beer at 8:30 in the morning, but it’s their night time,” said Colleen Clarke, who runs the camp during the day. Pat Cooper, the drill site manager, has been working in Antarctica since the early 1980s.
“The ‘Antarctic factor’ down here has a lot of influence on our drilling,” Cooper said.
Among the challenges this year was an April storm, which broke out some of the sea ice near where the drill site was planned to go. In August, a team flew down to check out the area and set up the camp.
“We didn’t really know for sure what was happening until we got down here at Winfly,” Cooper said.
But things looked good, and they decided to drill this year.
Now the project involves over 60 researchers and support staff. “It’s a mix of technology and science objectives,” said Peter Barrett, a member of the project’s management team.
A 60-ton drill rig sits on the sea ice, supported by the strength of the 8-foot-thick ice and under-ice balloons, which give an additional 11 tons of lift.
A 5-inch pipe, called the sea riser, provides the conduit in which the drill passes through the 980-foot-deep sea water. It must be freestanding and self-supporting to work properly. Suspending it from the sea ice only forces the ice to support more weight.
“It has to be totally independent of the systems up here,” Cooper said.
But it is impossible to stand a 980-foot-long 5-inch pipe on its end without help from above. The pipe is sunk 30 feet into the sea floor and is supported at the middle and the top by air bladders which pull up on the pipe to maintain the pipe’s rigidity and prevent it from bending or buckling too much.
They also have to deal with the movement of the sea ice itself. Under current conditions, the ice can move nearly 60 feet in any one direction before the angle of the drilling equipment will prevent it from working properly.
“To date we have moved off 6 meters (20 feet) from where we spotted in,” Cooper said.
The project has had the same drill crew for three years, which has made things easier every year, according to science coordinator Peter Webb.
“We’ve had amazing continuity,” Cooper said. “We’re a bit of a family, really, the old Cape Roberts team.”
When the core comes out of the hole, it begins a journey which will move it faster and further than ever before in its 40-million-year history.
It is removed from the core pipe and goes to the lab at the drill site for preliminary examination.
The core is examined, scanned, tested for physical properties, and split into an archive half, stored safely for the future, and a working half, from which samples will be taken at Crary Lab.
The working half is scanned again before the core goes on the helicopter to the camp and Crary. At $10,000 per yard of core, it’s worth a little extra time to photograph and scan everything in case of a helicopter accident or other disaster.
Some samples of the core are extracted at the drill site lab, to be used to determine more about the characteristics of the rocks being drilled, as well as to attempt to approximate an age for the rock layer.
The research is not just on the core itself, though. Some researchers are using the availability of a deep hole through many layers of rock to study the rock in situ.
Christian Buecker is one of these scientists. He does what is called “down-hole logging,” sending instruments down the hole to collect data about the rock around the hole, at intervals of a tenth of an inch.
The logging process takes a long time; 12 instruments run one at a time, at a speed of between three and 33 feet per minute, through about 1,150 feet of hole at a stretch. At the end of the last
logging run, Buecker had been awake for 44 of the previous 50 hours.
“We are looking for the physical and chemical properties,” Buecker said.
The data gathered helps them understand the core better, as well as the surrounding rock.
“It partly confirms our information and gives us new information about the structure,” Buecker said.
Among other things, Buecker has learned that the temperature at 2,500 feet down the hole (below the sea floor) is 68 F. It increases as they get closer to the center of the Earth.
But 3,084 feet is as close as the project will get to the Earth’s center. But in terms of both science and technology, this is not the end.
Camp manager Jim Cowrie has put in a proposal to the member countries of the Cape Roberts Project to set up a consortium of Antarctic drillers and researchers who use drilling as a method of gathering data.
Barrett is also making an effort to expand beyond just this three-year project. He hopes eventually to be able to drill through the center of the ice sheet, perhaps at Vostok, and into the
sediment below, to see what was happening in the center of Antarctica.
But even this work, in which the margins of the ice sheet are being studied, has been fruitful.
“It’s advanced the technology and advanced the science,” Barrett said. “We actually think this is fun.”

Present at the creation: Geologist Peter Webb got in on the ground floor of Antarctic research
Published in the Antarctic Sun
When Peter Webb left Antarctica in 1959, he thought he’d never be back. Not only was he wrong, but he’s now in the middle of his 20th season on the Ice.
A geology student at Victoria University in Wellington, New Zealand, Webb cajoled his way down
to the Ice in 1957 on a U.S. ship as a cargo handler.
With a friend, Barrie McKelvey, accompanying him, Webb was quickly snapped up by New Zealand and U.S. field parties for the International Geophysical Year (IGY). Both countries’ expeditions were long on geophysicists but short on geologists.
Webb spent the rest of that summer season in the field.
The following summer he returned to continue research associated with the IGY, and became one of the first people ever to explore the Dry Valleys.
Webb himself corresponded with and ended up meeting some of the geologists from Scott’s and Shackleton’s expeditions, who were still alive in the late 1950s.
“We headed inland to all the places they could never go,” he remembered.
Webb said he feels like he falls between eras. His first year in Antarctica was only 40 years after the age of the early explorers. His four decades since have centered on the scientific exploration of the continent.
“I often feel caught between those early expeditions and the present day,” he said.
The first part of that gap he bridged in U.S. helicopters over the Dry Valleys. The best maps they had were from early expeditions, which were closely tied to the coast and their supply ships.
“It was a very strange sensation to be holding a 1910-11 map on your knees in a helicopter in 1957,” Webb said. The maps weren’t all that complete. To find their way back to McMurdo, the pilots climbed in circles until they saw Erebus and headed that way. They had no other way of knowing where they were.
The Dry Valleys were so remote then that the only time Webb saw a helicopter was when it dropped him off and when it picked him up.
Between those times, Webb and three others spent their time walking. They set up two base camps, at Lake Vida and Lake Vanda, and “radiated out from there,” Webb said. They would carry supplies to outlying camps and then take day trips from those sites. They would climb high points and take photographic panoramas, which could later be patched together into maps.
“We were doing reconnaissance, mapping, and geology,” Webb said.
Once a week they would make radio contact via Morse code, relaying only the most basic information.
“We could have been dead six days and no one would have known,” Webb said.
They ate surplus Korean War military rations and pemmican, and had a hard time heating water. “It was all very primitive,” Webb said.
They collected rock samples, too, and all of those had to be carried by hand. The researchers would spend time collecting rocks from various places and then take a few days to hike them all
back to the nearest base camp—making several trips per day if necessary.
“One season we calculated we walked 1500 miles,” Webb remembered.
His feet aren’t worn out yet, and over 40 years later, he’s still coming to Antarctica. Now he’s the science leader for the Cape Roberts Project.
He comes for the learning, he said. “This is very good training for students.”
One of Webb’s former students now has a graduate student of his own; all three are members of the Cape Roberts team.
With such diverse minds focused on specific questions, Webb said, “it’s been a great problem-solving environment.”
The exposure to new possibilities has just appeared again, with the discovery of fossilized wood in the Cape Roberts core.
“This is a serendipitous environment,” Webb said. When planning research here, he allots 20 percent of the time for things he doesn’t yet know about.
He’s also impressed by the people who are here now.
“Back in 1957 the people who were here didn’t have a lot of interest in the place,” he said.
There was a time when Antarctica was something most people didn’t know anything about. Disinterest in the early days was such that students in his classes who had spent time in the Navy would see his slide shows, recognize places they’d been, but not even known they’d seen Antarctica.
“People would come up after class and say, ‘I think I’ve been to Antarctica,’” Webb said.
Now, though, the people here know a lot about Antarctica. “The level of education amongst the total current population is pretty good,” he said.
He is interested in seeing what happens to McMurdo as a community over the long term. “It’s unusual to take a group of people who don’t know each other and put them in this remote environment,” he said.
As for his own future, he’s not sure of specifics, but he’s confident. “Something always shows up.”
