Ocean-Based Actions Provide Big Opportunities to Curb Emissions
A new report outlines key areas to help mitigate emissions, including increased renewable energy, more efficient ocean-based transport, and advances in managing fisheries and aquaculture.
Seafood Farming: A Key to Future Global Food Security
Integration of sustainable marine and freshwater aquaculture with terrestrial agriculture will be necessary for meeting Earth’s future food requirements.
Gas Bubble Forensics Team Surveils the New Zealand Ocean
An international research group recorded the acoustic signatures of gas bubbles rising from a hydrothermal vent field to gather clues about greenhouse gases escaping into the atmosphere.
How Are Microplastics Transported to Polar Regions?
New modeling indicates that global subsurface ocean currents distribute submerged microplastics along very different routes than those traveled by floating plastic debris.
Grim Report on Climate Change Impacts on Oceans and Cryosphere
A new report by the Intergovernmental Panel on Climate Change states that bold actions can prevent significantly worse impacts.
A New Proxy for Past Precipitation
Researchers used luminescence signals from marine sediment cores to bolster estimates of precipitation levels on land over the past 30,000 years.
Ocean Observations for Everyone
As the ocean observation community expands its research enterprise, it needs to better engage the end users of its data.
Volcanic Eruption Creates Temporary Islands of Pumice
Rafts of pumice, spewed from an undersea volcano, recently appeared in the South Pacific. These transient, movable islands are important toeholds for marine life like barnacles, coral, and macroalgae.
