OAIC – give us input for NASA decadal survey

Do you do science related to the air-sea interactions? If so, we’d love to hear from you! Funding agencies often rely on the science community to identify and prioritize leading-edge scientific questions and required observations. NASA and its partners ask the National Research Council (NRC) once every decade to look out 10 years into the […]

Recent Science Highlights

OA could boost carbon export by appendicularia

Gelatinous zooplankton comprise a widespread group of animals that are increasingly recognized as important components of pelagic ecosystems. Historically understudied, we have little knowledge of how much key taxa contribute to carbon fluxes. Likewise, there’s a critical knowledge gap of the impact of ocean change on these taxa. Appendicularia are the most abundant gelatinous zooplankton […]

Quantifying uncertainties in future projections of Chesapeake Bay Hypoxia

Climate change is expected to especially impact coastal zones, worsening deoxygenation in the Chesapeake Bay by reducing oxygen solubility and increasing remineralization rates of organic matter. However, simulated responses of this often fail to account for uncertainties embedded within the application of future climate scenarios. Recent research published in Biogeosciences and in Scientific Reports sought […]

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 […]
