The ocean's biological carbon pump transfers carbon from the surface ocean to the deep
ocean by several distinct pathways, including gravitational settling of organic particles …

Western Atlantic bluefin tuna (ABT) undertake long-distance migrations from rich feeding
grounds in the North Atlantic to spawn in oligotrophic waters of the Gulf of Mexico (GoM) …

Enhanced vertical carbon transport (gravitational sinking and subduction) at mesoscale
ocean fronts may explain the demonstrated imbalance of new production and sinking …

The highly stratified, oligotrophic regions of the oceans are predominantly nitrogen limited in
the surface ocean and light limited at the deep chlorophyll maximum (DCM). Hence …

We performed nitrogen (N) budgets in the photic layer of three contrasting stations
representing different trophic conditions in the western tropical South Pacific (WTSP) Ocean …

In this study, we describe the dynamics of the sound scattering layers (SSLs), particularly
those of fish and macroplankton communities in the epipelagic layer, in the Seychelles …

The biological carbon pump (BCP) transports organic carbon from the surface to the ocean's
interior via sinking particles, vertically migrating organisms, and passive transport of organic …

Nitrification, the oxidation of ammonium to nitrite and then nitrate, is often discounted as a
source of nitrate in euphotic zone waters due to photoinhibition of nitrifying microorganisms …

During two cruises in the oligotrophic oceanic Gulf of Mexico, we deployed sediment traps at
three depths: center of the euphotic zone (EZ)(60 m), base of the EZ (117–151 m), and in the …

Abstract Eastern Boundary Current Upwelling Systems are regions of elevated primary
production and carbon export and thus play a central role in the global carbon cycle. In …
