Pumping Offshore Groundwater Resources Has Consequences on Land

by M. Bayani Cardenas 22 March 201917 June 2025

While vast volumes of fresh groundwater are located offshore, pumping these reserves can also deplete on-shore aquifers and cause land subsidence.

An Inherently Noisy Ocean Can Disguise Regional Sea Level Trends

by J. Sprintall 11 February 201921 February 2023

Sea level trends in different regions of the ocean caused by both natural and man-made changes in the atmosphere can be partially hidden by internal random processes intrinsic to the ocean.
