Apply to Attend Leaky Deltas Workshop in March 2025

OCB Scoping Workshop Leaky Deltas: Sources or sinks in the global carbon cycle? March 17-20, 2025 at Louisiana State Univ. (Baton Rouge, LA) River deltas and the adjacent coastal ocean are critical interfaces between terrestrial and oceanic environments. Deltas are the entry point of ~50% of the fresh water and 40% of all global particulate […]

Seeking community feedback on applications of GLIMR

The Geostationary Littoral Imaging and Monitoring Radiometer (GLIMR) mission will be NASA’s first geostationary, hyperspectral ocean color sensor to study ocean processes at the spatial and temporal scales required to observe the dynamic ecological, biogeochemical and physical processes typical of coastal and ocean waters. We would like to invite you to fill out a short survey (https://www.surveymonkey.com/r/GLIMR), to provide […]

Recent Science Highlights

Fast-sinking salp and fish detritus impacts OMZ size and ocean biogeochemical cycles

Marine fishes and filter-feeding gelatinous zooplankton such as salps and pyrosomes generate detritus in the form of poop and dead carcasses, which sink ~10 times faster than other oceanic detritus. This detritus is hypothesized to have a disproportionally large impact on the marine biological pump as it sequesters carbon and nutrients deeper in the water […]

The fate of the 21st century marine carbon cycle could hinge on zooplankton’s appetite

Both climate change and the efforts to abate have the potential to reshape phytoplankton community composition, globally. Shallower mixed layers in a warming ocean and many marine CO2 removal (CDR) technologies will shift the balance of light, nutrients, and carbonate chemistry, benefiting certain species over others. We must understand how such shifts could ripple through […]

Plankton plummet in one of the world’s longest time series

Phytoplankton are the main primary producers in the ocean and fuel marine food webs. Long-term shifts in phytoplankton biomass are useful for understanding the context of short-term changes and for examining the relationships between climate indices and phytoplankton dynamics. However, current monitoring programs often offer too short a time frame to disentangle these relationships. In […]

A New Insight into Ocean Carbon Sequestration

How does the microbial carbon pump (MCP) redefine our understanding of oceanic carbon sequestration and climate change mitigation? A recent study published in Nature Reviews Microbiology reviews the pivotal role of the microbial carbon pump (MCP) a novel concept differing from the known mechanisms for carbon sequestration in the ocean, the Biological Carbon Pump (BCP), […]

Out of sight, out of mind: extreme signals of ocean acidification hidden in the mesopelagic

Ocean Acidification (OA), caused by the air-to-sea transfer of anthropogenic carbon (Cant), is intuitively thought to be a surface-intensified process, which makes sense because the concentration of Cant is greatest near the ocean surface and decreases with depth. But this intuition is not correct for multiple metrics of OA that are less commonly studied below […]

An unexpected shift to a later phytoplankton bloom in the West Antarctic Peninsula

Polar regions are changing: warming, losing sea ice, and experiencing shifts in the phenology of seasonal events. Global models predict that phytoplankton blooms will start earlier in these warming polar environments. What we don’t know is will this be true for all high-latitude regions? Is the timing of phytoplankton growing season moving earlier in the […]
