Carbon sequestration by multiple biological pump pathways in a coastal upwelling biome [PDF]
Nature Communications, 2023 Multiple processes transport carbon into the deep ocean as part of the biological carbon pump, leading to long-term carbon sequestration. However, our ability to predict future changes in these processes is hampered by the absence of studies that have ...

Sea Ice Loss leads to regime shifts in the arctic biological pump [PDF]
Nature CommunicationsThe Arctic Ocean has undergone accelerated warming and a marked decline in sea ice over recent decades. Yet, the response of the biological pump—a critical mechanism for atmospheric carbon sequestration—remains poorly understood.

Ecotoxicology and Environmental Safety, 2021 The distribution of hydrophobic organic contaminants (HOCs) in eutrophic ecosystems has been widely studied, but how phytoplankton blooms affect their occurrence and benthic bioaccumulation is poorly understood. To fill this knowledge gap, the biological

Exploring the ecology of the mesopelagic biological pump
Progress in Oceanography, 2019 The oceans’ biological pump (BP) exports large amounts of particulate organic carbon (POC) to the mesopelagic zone (base of the euphotic zone – 1000 m depth). The efficiency at which POC is transferred through the mesopelagic zone determines the size of the deep ocean carbon store. Few observational BP studies focus on the mesopelagic, often leading to

Vertically migrating Isoxys and the early Cambrian biological pump. [PDF]
Proc Biol Sci, 2021 The biological pump is crucial for transporting nutrients fixed by surface-dwelling primary producers to demersal animal communities. Indeed, the establishment of an efficient biological pump was likely a key factor enabling the diversification of ...

Evolution of the ocean's "biological pump". [PDF]
Proc Natl Acad Sci U S A, 2011 Earth history is punctuated by a huge variety of transitions and perturbations in climate and global biogeochemical cycles. These may be linked to major extinctions or evolutionary innovations, and may exhibit evidence for greenhouse warming and CO2 release and hence potentially hold direct future-relevant information (1) or may be associated with ice ...

Enhanced marine biological pump as a trigger for the onset of the late Paleozoic ice age. [PDF]
Sci AdvThe mid-Tournaisian carbon isotope excursion (TICE) represents the largest positive carbon isotope excursion in the late Paleozoic, coinciding with the onset of the late Paleozoic ice age (LPIA). Here, to investigate changes in the marine biological pump

Decoding drivers of carbon flux attenuation in the oceanic biological pump. [PDF]
NatureThe biological pump supplies carbon to the oceans’ interior, driving long-term carbon sequestration and providing energy for deep-sea ecosystems1,2. Its efficiency is set by transformations of newly formed particles in the euphotic zone, followed by ...

The Oceanic Biological Pump: Rapid carbon transfer to depth at Continental Margins during Winter. [PDF]
Sci Rep, 2017 The oceanic biological pump is responsible for the important transfer of CO2-C as POC “Particulate Organic Carbon” to the deep sea. It plays a decisive role in the Earth’s carbon cycle and significant effort is spent to quantify its strength.

The reduction in the biomass of cyanobacterial N2 fixer and the biological pump in the Northwestern Pacific Ocean. [PDF]
Sci Rep, 2017 The comparison of sediment trap data with physical and biogeochemical variables in the surface water column of the Tropical Northwestern Pacific Ocean (TNWPO) indicated that the magnitude of the springtime biological pump has reduced with time due to a ...
