The contribution of deep chlorophyll maxima to net primary production in the Southern Ocean Global Biogeochemical Cycles, 2025 (Ref: 17431)
Category 1: Peer-reviewed literature

Deep chlorophyll maxima (DCMs) have long been studied in the northern hemisphere but have received less attention in the Southern Ocean. Their contribution to phytoplankton biomass and net primary productivity (NPP) is poorly resolved. Recently…

Southern Ocean carbon export revealed by backscatter and oxygen measurements from BGC-Argo floats Global Biogeochemical Cycles, 2025 (Ref: 17334)
Category 1: Peer-reviewed literature

The Southern Ocean (south of 30°S) contributes significantly to global ocean carbon uptake through the solubility, physical and biological pumps. Many studies have estimated carbon export to the deep ocean, but very few have attempted a basin-scale perspective, or accounted for the sea-ice zone…

Iron and light limitation of phytoplankton growth off East Antarctica Journal of Marine Systems, 2022 (Ref: 16547)
Category 1: Peer-reviewed literature

Phytoplankton production controls the transfer of carbon dioxide from the atmosphere into the ocean through the biological carbon pump, facilitating the sequestration of carbon dioxide and thus, contributing to the regulation of global climate. In the Southern Ocean…

Drivers of Air-Sea CO2 Flux in the Subantarctic Zone Revealed by Time Series Observations. Global Biogeochemical Cycles, 2024 (Ref: 17100)
Category 1: Peer-reviewed literature

The subantarctic zone is an important region in the Southern Ocean with respect to its influence on air-sea CO2 exchange and the global ocean carbon cycle. However, understanding of the magnitude and drivers of the flux are still being refined.

Subsurface chlorophyll maxima reduce the performance of non-photochemical quenching corrections in the Southern Ocean. Frontiers in marine Science, 2024 (Ref: 17096)
Category 1: Peer-reviewed literature

Non-photochemical quenching (NPQ) within phytoplankton cells often causes the daytime suppression of chlorophyll fluorescence in the Southern Ocean.
