Ocean Carbon & Biogeochemistry

How will increasing meltwater from Greenland affect the biogeochemistry of the ocean? Release of meltwater into the ocean has physical and biogeochemical effects on the local water column. With respect to nutrient availability, meltwater supplies the bioessential nutrients iron and silicic acid but is deficient in nitrate and phosphate. However, despite very low meltwater nitrate […]

The presence of large-scale Ekman downwelling is the textbook explanation for low nutrient concentrations, and hence low productivity, in subtropical gyres. However, recent research has suggested that mesoscale eddies oppose and substantially reduce this downwelling, a process known as eddy cancellation (Doddridge et al, 2016). Eddy cancellation represents a substantial alteration to the widely accepted […]

Beatriz Dias is a Ph.D. candidate at the University of Massachusetts Amherst, Department of Environmental Conservation. Her work includes developing models to aid management decision making in Northeast US large marine ecosystem and Northern Brazil. Her work includes exploring different fisheries management scenarios effects on marine food webs and identifying monitoring priority areas for species of […]

The following SSC members are scheduled to rotate off at the end of 2018: Dennis McGillicuddy (WHOI) – physical-biological interactions in the open ocean and coastal margins, mesoscale dynamics, biogeochemical cycling, zooplankton population dynamics Anton Post (FAU) – biology of algae and its ecology, evolution and genomics Andrew Barton (SIO) – marine ecosystem tipping points, […]

Western boundary current (WBC) regions display the largest magnitude air-to-sea carbon dioxide (CO2) fluxes of anywhere in the global ocean, exhibit large spring blooms and high eddy activity, and are hubs for the subduction of anthropogenic carbon-laden waters into the ocean interior during mode water formation. Yet the influence of biophysical interactions on air-sea CO2 […]
