Typhoons Mix Up Bacteria and Biochemistry

by Rebecca Dzombak 10 July 20269 July 2026

After a typhoon surprised a research cruise, scientists took advantage of the unique sampling opportunity to reveal rapid changes in bacterioplankton communities and biogeochemical cycling.

A satellite image shows a river flowing into the ocean. The river is brown compared to the blue of the ocean, and it is distributing a plume of silt into the ocean. The landscape around the water is green.

A Long-Term Look Beneath an Antarctic Ice Shelf

by Nathaniel Scharping 6 March 20269 March 2026

More than 4 years of data from a borehole in the Ross Ice Shelf reveal supercooled water and more.

Two circular images show views from a kayak, one looking ahead and one looking behind. The image at left shows a glacier straight ahead, as well as the front of the kayak lined with orange flotation devices. The image at right shows the back of the boat and a clear trail of water through an area mostly covered with ice chunks.

A First Look at How Sand Behaves Inside a Rippled Bed

by Ryan P. Mulligan 11 September 202511 September 2025

A detailed numerical model shows how sediment particles experience wave-driven shear stress inside and above a sea bed with sand ripples.

Four warmly dressed scientists stand around a large metal rig taller than them that is drilling a hole into the ice they are standing on. More scientists stand in the background, and a crane is stretched over the metal rig, lowering a cable into the hole.
