We have been working on an eco-friendly drogued drifter.  It is a star-shaped drogue (made like some of the commercial surface drifters sold on the west c […]

Now that  dozens of the new aluminum-framed “Irina” drifters have been deployed, we can assess their performance. The one problem seems to be that, while the  ⅜”  spars do not break, […]

As reported last year, our latest surface drifter has an aluminum frame. Dozens of these “Irinas” have now been deployed with varying success but, in […]

True to its name, Project CONVERGE brought together people from all over the world to study the food web at Palmer Station. But now our month on the ice is over, and it’s time for us to go back home; in other w […]

The Antarctic Peninsula is one of the fastest warming places on Earth. Around Palmer Station, the average winter temperature has risen by more than 10 degrees Fahrenheit in the last 50 years. That might sound slow […]

Many years ago, when your trusty blog writer and photographer were little, we used to open up each new issue of National Geographic’s kids magazine and look for a feature called “What in the World?” It was a quiz […]

Much is made of Antarctica’s incredible wildlife: throngs of krill; seals piled together like rolls of carpet; regiments of penguins; whales puffing clouds into the sky. But there’s a creature arguably more […]

We spend a lot of time looking at penguins down here, but they’re not the only birds around. An almost constant presence overhead is the aptly named southern giant-petrel—the biggest flying bird in Antarctica. […]

Sunday morning dawned clear and calm—only the second truly sunny day since we arrived at Palmer Station. It was a perfect opportunity for Dr. Josh Kohut to tick the second big item off his to-do list: a trip […]

Earlier this week the glider team pulled in the University of Delaware’s glider, nicknamed the “Blue Hen,” from the ocean. They needed to change its batteries and download one of the instrument’s data. But they […]

Ever since January 15, Dr. Josh Kohut has spent each evening looking hopefully at the weather forecast. He needs one day of calm winds to do some radar maintenance at the Wauwerman Islands. Though they’re only 10 […]

We’re still trying to get to the Wauwerman Islands to do some work on the radar station there, but once again today the weather did not quite cooperate. In the meantime, life goes on at the station. Boats go in […]

This morning we woke up to find an Antarctic fur seal napping on the rocks about a hundred yards from our front door. It was a welcome surprise—we had seen fur seals on our visit to Livingston Island on January 1, […]

Donna Fraser remembers the day in 1993 when her team found the first gentoo penguin nests ever recorded at Biscoe Point. Fourteen pairs had set up a tiny colony on the rocky headland, which lies just 8 miles from […]

The scientists spent Sunday doing maintenance on a glider, checking giant-petrel and skua nests, looking for whales, and counting krill for as long as the choppy water and the sharp south winds allowed. Dr. Josh […]

In calm winds this morning we loaded the zodiacs with the safety gear we had assembled yesterday. But even as we put on our flotation suits and boarded the boats, the sky was graying and a strengthening breeze was […]

Antarctica is a lot less dangerous than it used to be, when people like Ernest Shackleton explored it in the early twentieth century. But it’s still cold, windy, powerful, and very far from help. The U.S. […]

In yesterday’s post, the glider team took a calculated risk and brought glider RU05 into the shallow waters near shore. We made a big deal about how dangerous this was—how the waters near shore are full of […]

The gliders have been out on their own for more than a week. In that time they’ve traveled far out to sea, but today the team decided to turn one of them around and bring it almost all the way back home. Being […]
