Capacity Building in Physical Chemistry for Oceanography

Earlier this year, we conducted an online survey and consultation with the broader ocean science community to assess what we perceive as emerging skills gaps in basic physical chemistry training and expertise in several areas of chemical oceanography, especially (but not exclusively) including the ocean carbonate system. In the survey, we asked just for this […]

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

Swirling Currents: How Ocean Mesoscale Affects Air-Sea CO2 Exchange

Due to a sparsity of in‐situ observations and the computational burden of eddy‐resolving global simulations, there has been little analysis on how mesoscale processes (e.g., eddies, meanders—lateral scales of 10s to 100s km) influence air‐sea CO2 fluxes from a global perspective. Recently, it became computationally feasible to implement global eddy‐resolving [O (10) km] ocean biogeochemical […]

How tiny teeth and their prey shape ocean ecosystems

It has long been suggested that diatoms, microscopic algae enclosed in silica-shells, developed these structures to defend against predators like copepods, small crustaceans that graze diatoms. Copepods evolved silica-lined teeth presumably to counteract this. But actual evidence for how this predator-prey relationship may drive natural selection and evolutionary change has been lacking. A recent publication […]

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), […]
