How Did We Get Here?
With a discovery made from fossils in the seabed, paleoceanographers and paleoclimatologists began tracing the delicate path between ancient eras and our future.
NOAA Budget Proposal Hits Rough Waters in Congress
The budget proposed by the Trump administration would cut NOAA’s budget by 18%. It would target climate and ocean research programs and also slash education initiatives, grants, and other agency programs.
Ancient River Discovery Confirms Mediterranean Nearly Dried Up in the Miocene
Sedimentary deposits reveal a Nile-sized river system flowing from what are today Turkey and Syria.
Wrinkles and Bumps in the Gulf Stream
Observations of tiny vortices in the ocean interior provide hints of a dynamic richness of the deep ocean that we are yet to fully appreciate.
Pumping Offshore Groundwater Resources Has Consequences on Land
While vast volumes of fresh groundwater are located offshore, pumping these reserves can also deplete on-shore aquifers and cause land subsidence.
When the River Meets the Sea: Estuary Sediments and Hypoxia
Scientists know that low-oxygen dead zones are growing worldwide. New research sheds light on what that will mean for estuary systems if trends continue.
A 192,000-Year Record of Northwest African Fire History
Biomarker analyses from an offshore sediment core suggest that increased fire occurrence around 55,000 years ago coincided with increased fuel loads and human settlement in this region.
