Abstract The Southern Ocean serves as the primary gateway through which the
intermediate, deep, and bottom waters of the ocean interact with the surface ocean (and thus …

Quantifying the strength and efficiency of the Southern Ocean biological carbon pump (BCP)
and its response to predicted changes in the Earth's climate is fundamental to our ability to …

Marine heatwaves (MHWs) represent anomalously warm temperature conditions of
seawater that may affect marine life and ocean biogeochemistry. Under such conditions …

Abstract The Antarctic Marginal Ice Zone (MIZ) accounts for 15% of the Southern Ocean's
primary production (PP), but limited data has hindered understanding of its variability and …

Marine phytoplankton are essential to ocean biogeochemical cycles. However, our
understanding of changes in phytoplankton rely largely on satellite data, which can only …

We use observations from the Southern Ocean (SO) biogeochemical profiling float array to
quantify the meridional pattern of particle export efficiency (PEeff) during the austral …

This paper provides an overview and demonstration of emerging float-based methods for
quantifying gross primary production (GPP) and net community production (NCP) using …

Marine phytoplankton biomass and chlorophyll-a concentration are often estimated from
pigment fluorescence measurements, which have become routine despite known variability …

Phytoplankton contribute approximately half of the Earth's primary production, playing a
crucial role in marine ecosystem functioning and global carbon cycling. However, our …

Spaceborne observations of primary production (PP) are essential for understanding the
role of phytoplankton in the biogeochemical cycles on a global or regional scale. In this …
