Vetlesen Prize Ceremony Honors Two Distinguished Researchers in Earth Sciences
A celebration held at Columbia University recognized scientists Anny Cazenave and David Kohlstedt as the 2020 and 2023 Vetlesen Prize recipients.
A celebration held at Columbia University recognized scientists Anny Cazenave and David Kohlstedt as the 2020 and 2023 Vetlesen Prize recipients.
For the International Day of Women and Girls in Science, world-renowned geophysicist Anny Cazenave discusses her research journey, the Vetlesen Prize, and her hopes for younger women scientists entering the field.
A grad student and his colleagues search for innovative new ways to detect and disarm millions of hidden hazards.
Christine McCarthy, a geophysicist at the Lamont-Doherty Earth Observatory, scrunches blocks of ice between hunks of rock to study how ice behaves under pressure. Her work provides an important piece of the puzzle of how glaciers move, what makes them speed up, and how they are contributing to sea level rise as the climate warms.
In the islands off Papua New Guinea, the rocks are giving rise to new ideas about the ways mountain chains form. A new scientific model shows how two seemingly opposite processes can take place in the same region.
After a surprisingly smooth crossing of the Southern Ocean, with favorable winds we arrived back in Hobart, Tasmania. The weather maps show that we just got ahead of another big storm system.
In addition to understanding potential pathways for “warmer” circumpolar deep water to reach the ice shelf, we are also measuring what the structure and properties of the water column are and determining if there is already warmer water on or near the continental shelf that could already interact with the glaciers of East Antarctica today.
One of the goals of this expedition is to investigate if water from the Southern Ocean with temperatures above the melting point of glaciers could reach the glaciers in East Antarctica, and if there are any obstacles on the seafloor of the shelf that impact the ability of such water to reach the glaciers and ice streams.
Several days ago we reached our main work areas along the margin of East Antarctica. Our expedition is relatively late in the season and the seas around Antarctica are starting to freeze.
We are less than a day away from our first study area on the continental shelf in front of the Dibble Glacier. As we approach Antarctica we are starting our science program with a 4500 meter deep CTD and multibeam acquisition.
