The Lost Topography Around Continental Rifts

by Fabio A. Capitanio 28 April 202225 April 2022

Numerical models provide quantitative constraints on topography lost to erosion, showing how the sediment influx in a sedimentary basin reflects its tectonic and topographic evolution.

Why is Permafrost Groundwater Surfacing?

by Victor Bense 21 April 202214 April 2022

Hydrogeological properties of degrading permafrost come to fruition with a new 3-D modeling study that highlights the increasing role of groundwater in the water cycle of high-latitude areas.

How Are Microplastics Transported to Polar Regions?

by Terri Cook 26 September 2019

New modeling indicates that global subsurface ocean currents distribute submerged microplastics along very different routes than those traveled by floating plastic debris.

Can the North Brazil Current Help Us Understand Atlantic Water Flow?

by David Shultz 24 December 201524 December 2015

Currents off the coast of northern Brazil can be used to study changes in the larger oceanic circulation pattern in the Atlantic, when variable winds in the regions are properly accounted for.
