The biological pump transports organic matter, created by phytoplankton productivity in the
well-lit surface ocean, to the ocean's dark interior, where it is consumed by animals and …

The Argo Program has been implemented and sustained for almost two decades, as a
global array of about 4000 profiling floats. Argo provides continuous observations of ocean …

Consistent, cross-mission retrievals of near-surface concentration of chlorophyll-a (Chla) in
various aquatic ecosystems with broad ranges of trophic levels have long been a complex …

Human activities have altered the state of the ocean, leading to warming, acidification and
deoxygenation. These changes impact ocean biogeochemistry and influence ecosystem …

Biogeochemical-Argo (BGC-Argo) is a network of profiling floats carrying sensors that
enable observation of as many as six essential biogeochemical and bio-optical variables …

Rivers and other freshwater systems play a crucial role in ecosystems, industry,
transportation and agriculture. Despite the> 40 years of inland water observations made …

A critical driver of the ocean carbon cycle is the downward flux of sinking organic particles,
which acts to lower the atmospheric carbon dioxide concentration. This downward flux is …

Stratified oceanic systems are characterized by the presence of a so‐called Deep
Chlorophyll a Maximum (DCM) not detectable by ocean color satellites. A DCM can either …

Phytoplankton blooms are an important, widespread phenomenon in open oceans, coastal
waters and freshwaters, supporting food webs and essential ecosystem services. Blooms …

Abstract The Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM)
program has begun deploying a large array of biogeochemical sensors on profiling floats in …
