Impact of hydrothermalism on the ocean iron cycle [PDF]
, 2016 As the iron supplied from hydrothermalism is ultimately ventilated in the iron-limited Southern Ocean, it plays an important role in the ocean biological carbon pump. We deploy a set of focused sensitivity experiments with a state of the art global model

Seasonal copepod lipid pump promotes carbon sequestration in the deep North Atlantic [PDF]
, 2015 Physical, chemical and biological processes can mediate carbon transfer from surface ocean waters to below the permanent pycnocline and so promote ocean carbon sequestration.

Impact of atmospheric and terrestrial CO2 feedbacks on fertilization-induced marine carbon uptake [PDF]
, 2009 The sensitivity of oceanic CO2 uptake to alterations in the marine biological carbon pump, such as brought about by natural or purposeful ocean fertilization, has repeatedly been investigated by studies employing numerical biogeochemical ocean models. It

Variations in the biological pump throughout the Miocene: evidence from organic carbon burial in Pacific Ocean sediments [PDF]
Climate of the PastThe biological pump, defined as the marine biological production and sedimentation of particulate organic carbon (POC), is a fundamental process for fixing atmospheric carbon dioxide in the oceans, transferring carbon away from the atmosphere to the deep

Evolving paradigms in biological carbon cycling in the ocean [PDF]
, 2018 Carbon is a keystone element in global biogeochemical cycles. It plays a fundamental role in biotic and abiotic processes in the ocean, which intertwine to mediate the chemistry and redox status of carbon in the ocean and the atmosphere. The interactions

Mechanisms of microbial carbon sequestration in the ocean – future research directions [PDF]
, 2014 This paper reviews progress on understanding biological carbon sequestration in the ocean with special reference to the microbial formation and transformation of recalcitrant dissolved organic carbon (RDOC), the microbial carbon pump (MCP).

The Ocean's Biological Carbon pump as part of the global Carbon Cycle [PDF]
Limnology and Oceanography e-Lectures, 2014 SummaryThe Biological Carbon Pump includes all those processes in the ocean that cause organic carbon formed photosynthetically by phytoplankton (primary production) in the sunlit surface layer (the euphotic zone) to be removed from contact with the atmosphere.

Radiocarbon constraints on the glacial ocean circulation and its impact on atmospheric CO2
Nature Communications, 2017 Establishing the efficiency of the biological carbon pump is needed to constrain the impact of ocean circulation on the carbon cycle. Here, the authors compile a global array of ocean–atmosphere radiocarbon disequilibrium estimates and evaluate the ...
