Simulations of tropical ocean convection help distinguish climate effects resulting from large-scale changes in atmospheric circulation from those resulting from higher temperatures.
Oceans
Jellies Transfer a Significant Amount of Carbon to the Deep Ocean
Jellyfish and sea salps aren’t getting the credit they deserve for their role in ocean carbon cycling, according to a new study.
The Ocean-Land Connection of Droughts
Around 16 percent of large-scale droughts over land originate above the ocean and these types of droughts are more extensive and severe than droughts that originate over land.
Experimenting with Underwater Sediment Slides
Sediment-laden currents caused by breaching flow slides are hazardous to flood defenses and seabed infrastructure. New research shows that these phenomena must be accounted for in erosion simulations.
Earthquakes Reveal How Quickly the Ocean Is Warming
By timing sound waves set in motion by earthquakes, scientists have estimated that the Indian Ocean is warming by roughly 0.044 K per decade.
Lovenduski Receives 2019 Ocean Sciences Early Career Award
Nicole S. Lovenduski received the 2019 Ocean Sciences Early Career Award at AGU’s Fall Meeting 2019, held 9–13 December in San Francisco, Calif. The award recognizes “significant contributions to” and “future promise within the ocean sciences.”
Improving Proxy Representations of Ocean Properties
Many oceanic properties are not directly observed but are instead estimated using proxy measurements. A new method uses physics-based correlations to reduce uncertainty in this relationship.
What the Upper Ocean Looks Like During a Hurricane and Why It Matters
High-resolution measurements reveal the structure of the upper ocean under a hurricane and its feedback on storm intensity.
Deep-Ocean Oxygen May Increase with Climate Change
A millennial-scale ocean simulation indicates that oxygen gains in the deep ocean may offset oxygen losses in the upper water layer under a protracted climate change scenario.
Dams Alter Nutrient Flows to Coasts
New models indicate how dams worldwide influence the mix of nutrients in river water reaching the ocean. As more dams are built, changing nutrient loads may adversely affect coastal ecosystems.
