Ocean Carbon & Biogeochemistry

OCB at OSM24

OCB will have a booth at the OSM24 exhibitor hall – come see us there during open hours. SSC members and Project Office staff will be at the booth to talk all things OCB and answer your questions about getting more involved. Stay tuned for OCB-hosted sessions and town halls during OSM.

International FAIR Data Workshop POSTPONED

International Workshop: FAIR Data Practices for Ship-based Ocean Time Series DATES POSTPONED OVERVIEW: Sustained ocean time series measurements are fundamental to distinguish between natural and human-induced variability in ecosystems and processes required to advance ecological forecasting. The last international ship-based ocean time series workshop, held in November 2012 (Bermuda), focused on recommendations to improve data […]

Recent Science Highlights

Fishing Vessel Ocean Observing Network (FVON) reimagines the global data collection paradigm

With an increasingly wide variety of technology and innovations, from buoys to satellites, we now understand the open ocea n better than ever. Yet, existing technologies cannot cost-effectively provide accurate, up-to-date data on coastal and shelf ocean environments, especially beneath the surface. These dynamic regions impact billions of people in profound and varied ways. As described […]

Want to improve the spatiotemporal coverage of coastal water clarity? This approach combines high-resolution satellite data with low-cost in situ methods

To maintain marine ecosystem health and human well-being, it is important to understand coastal water quality changes. Water clarity is a key component of water quality, which can be measured in situ by tools such as Secchi disks or by satellites with high spatial and temporal coverage. Coastal environments pose unique challenges to remote sensing, […]

New evidence suggests that tiny zooplankton might be the biggest problem with carbon cycling in IPCC climate models

The ocean is the most important sink of anthropogenic emissions and is being considered as a medium to manipulate to draw down even more. Essential in the ocean’s role as a natural carbon-sponge is the net production of organic matter by phytoplankton, some of which sinks and is stored for 100s-1000s of years. Successfully simulating […]

Size does matter: larger krill leads to more POC export in the West Antarctic Peninsula

Despite the importance of particulate organic carbon (POC) export on carbon sequestration and marine ecology, there have been few multi-decade studies in the world’s oceans. A new analysis published in Nature analyzed two decades of POC export data in the West Antarctic Peninsula and found that export oscillates on a 5-year cycle. Using a unique […]

A suite of CO2 removal approaches modeled for the 1.5 ˚C future

Carbon dioxide removal (CDR) is “unavoidable” in efforts to limit end-of-century warming to below 1.5 °C. This is because some greenhouse gas emissions sources—non-CO2 from agriculture, and CO2 from shipping, aviation, and industrial processes—will be difficult to avoid, requiring CDR to offset their climate impacts. Policymakers are interested in a wide variety of ways to draw […]

Insights into Lagrangian phytoplankton variability from profiling floats

Phytoplankton are small, drifting photosynthetic organisms that form the base of marine food webs and play an important role in carbon and nutrient cycling. Analyses of how they vary in space and time (through variables like the concentration of pigment chlorophyll-a, a proxy for their biomass) are therefore important. Because phytoplankton drift with ocean currents, […]
