Ocean animals at the top of the food chain recovered first after a cataclysm at the end of the Permian period. The extinction was triggered by events resembling the changes brewing in today’s oceans.

Observing Winter Mixing and Spring Bloom in the Mediterranean
A new special issue of JGR: Oceans and JGR: Atmospheres presents new insights into the dynamics of dense water formation in the western Mediterranean Sea and its biogeochemical consequences.
Christopher N. K. Mooers (1935–2018)
This passionate physical oceanographer, a leader and catalyst in coastal studies, explored many facets of nearshore circulation and advanced the modeling and forecasting of coastal dynamics.
A Cross-Sectoral Approach to Tackle Ocean Plastic Pollution
Plastic in the Oceans: Challenges and Solutions; Cambridge, United Kingdom, 7 March 2018
Dispersal of River Water by Ocean Eddies and Shallow Ekman Flow
Low-salinity water from the Ganga-Brahmaputra river is transported by mesoscale eddies in the Bay of Bengal, but when the monsoon winds strengthen, a shallow “Ekman” flow dominates dispersal of water.
Ocean Research and Education Are Foundations for Economic Growth
AGU releases revised position statement that was first adopted in 2005.
Successful Testing of Technique to Measure Seafloor Strain
A new optical fiber interferometry strain sensor tested off the Oregon coast holds promising prospects for seafloor geodesy.
Massive Ocean Waves May Play a Role in Nuisance Flooding
When huge planetary waves that spawn in the open ocean reach land, they can raise local sea levels along the coast. Could tracking these waves help scientists predict flooding months in advance?
Illegal Seafood Supply Chains Can Now Be Tracked by Satellite
Researchers pinpoint more than 10,000 likely transfers of catches between fishing vessels and cargo ships at sea. Knowing where these transfers occur can help officials crack down on illegal activity.
Carbonate Melting Enhances Mantle CO2 Fluxes in Old Ocean Basins
The amount of CO2 segregated from the mantle by carbonate melting beneath old oceanic crust may equal that emitted along the mid-ocean ridge system, thereby contributing to the global carbon cycle.
