Unveiling pelagic-benthic coupling associated with the biological carbon pump in the Fram Strait (Arctic Ocean) by Simon Ramondenc, Damien Eveillard, Katja Metfies, Morten H. Iversen, Eva-Maria Nöthig, Dieter Piepenburg, Christiane Hasemann, Thomas Soltwedel

“…Spatiotemporal changes in community composition show decreasing diatom abundance during warm anomalies, which would reduce the efficiency of a diatom-driven biological carbon pump. Interestingly, several parasites are also tightly associated with carbon flux and show a strong vertical connectivity, suggesting a potential role in sedimentation processes involving their hosts, especially through interactions with resting spores, which could have implications for pelagic-benthic coupling and overall ecosystem functioning.…”

Carbon injection potential of the mesopelagic-migrant pump in the Southern Ocean during summer by Katherine Baker, Katherine Baker, Svenja Halfter, Svenja Halfter, Ben Scoulding, Kerrie M. Swadling, Kerrie M. Swadling, Shane A. Richards, Matthieu Bressac, Matthieu Bressac, Caroline A. Sutton, Philip W. Boyd, Philip W. Boyd

“…The passive sinking flux of particles, termed the biological gravitational pump (BGP), is an important component of the ocean’s biological carbon pump. In addition, carbon-rich particles are actively injected to depth through the diel vertical migration (DVM) of micronekton and mesozooplankton from the surface to the oceans’ twilight zone (200 m – 1000 m depth). …”

Particle fluxes by subtropical pelagic communities under ocean alkalinity enhancement by P. Suessle, J. Taucher, S. U. Goldenberg, M. Baumann, K. Spilling, K. Spilling, A. Noche-Ferreira, A. Noche-Ferreira, M. Vanharanta, M. Vanharanta, U. Riebesell

“…By changing the carbonate speciation in seawater, OAE may potentially alter marine ecosystems with implications for the biological carbon pump. Using mesocosms in the subtropical North Atlantic, we provide first empirical insights into impacts of carbonate-based OAE on the vertical flux and attenuation of sinking particles in an oligotrophic plankton community. …”
