New research suggests that combining ship- and float-based observations provides a more accurate measure of how much carbon the Southern Ocean absorbs.
Biogeochemical cycles, processes, and modeling
Addressing Arctic Challenges Requires a Synoptic Ocean Survey
A coordinated effort involving trailblazing science—and icebreaking ships—from many nations is needed to fill gaps in our understanding of the Arctic Ocean and how it’s changing.
Revealing the Ocean’s Rare but Prolific Carbon Export Events
New findings suggest that rare events underlie a global inverse relationship between primary production of organic carbon in the upper ocean and the fraction that is exported to the deep sea.
Progress and Planning in Understanding Ocean Acidification
The 4th Global Ocean Acidification Observing Network (GOA-ON) International Workshop; Hangzhou, China, 14–17 April 2019
Tracking Dissolved Organic Matter in Coastal Ecosystems
Dissolved organic matter supports aquatic food webs and holds as much carbon as the atmosphere. A new study tracks which sources and processes play the biggest role in coastal systems.
Pacific Carbon Ages During Long Journey Along Ocean Floor
The radiocarbon signal of DOC with depth across the Pacific Ocean basin effectively supports a number of important theories that have been suggested over the years.
Pacific Carbon Uptake Accelerating Faster Than Expected
A new study suggests that shifting ocean currents drive faster carbon dioxide uptake.
Sea-Surface Carbon Patterns Linked to Large-scale Climate Modes
A new 34-year global time series of observed sea surface partial pressure of CO2 links regional variation to major climate modes.
Radionuclide Data from GEOTRACES Improve Particle Flux Estimates
New measurements of multiple radionuclides in the Atlantic Ocean offer a robust constraint on the sinking flux of particles and associated vertical fluxes of biogeochemically important elements.
Tool to Capture Marine Biological Activity Gets Coastal Upgrade
Upwelling hinders an efficient method to estimate a key measure of biological productivity in coastal waters, but accounting for surface temperatures could boost accuracy.
