Dale Andersen's Antarctic Field Season
16 March 2026

The team has returned from Antarctica and is transitioning from fieldwork to analysis, focusing on incoming samples, collected data, and upcoming lab work. Planning is already underway for the next field season, just seven months away, as research continues as an ongoing cycle rather than a single expedition.

#PPOD: When they form, impact craters dig up material from below the surface and throw it outwards into what geologists call an ejecta blanket. The fastest ejected material travels the furthest, so material from different depths can end up at different distances from the crater.

This HiRISE image shows a pedestal crater in Arcadia Planitia, Mars, with material of varying brightness and color at different distances from the crater.

The 118-km-long Øresund Strait (also known as the Sound) separates Denmark to the west from Sweden to the east and links the Baltic Sea to the North Sea, which makes it one of the busiest waterways in the world.

In this image, ships appear as bright, sparkly dots in the dark waters of the strait.

In the latest episode of The Climate Chronicles, The Hottest Holocene, Professor Degroot asks a simple question: when was the last time that the Earth was as hot as it is today? It may be a simple question, but it has a complicated answer – one that touches on everything from schemes for nuclear missile silos in the Greenland Ice Sheet at the height of the Cold War, to ancient computers in long-forgotten shipwrecks.

According to Irish mythology, hunter and warrior Finn McCool bathed in the lake on Slieve Gullion and emerged decades older. However, we don’t need a dip in the lake to move through time. A glance at the landscape reveals millions of years of history.
