Influence of the phytoplankton community structure on the spring and annual primary production in the northwestern Mediterranean Sea

N Mayot, F d'Ortenzio, J Uitz, B Gentili… - Journal of …, 2017 - Wiley Online Library
Satellite ocean color observations revealed that unusually deep convection events in 2005,
2006, 2010, and 2013 led to an increased phytoplankton biomass during the spring bloom …

Temperature‐regulated turnover of chromophoric dissolved organic matter in global dark marginal basins

C Wang, W Guo, Y Li, RA Dahlgren… - Geophysical …, 2021 - Wiley Online Library
Oceanic absorption of heat generated by greenhouse gas emissions has resulted in
warming of the dark ocean (> 200 m) that contains a large refractory DOM (RDOM) pool …

Resupply of mesopelagic dissolved iron controlled by particulate iron composition

M Bressac, C Guieu, MJ Ellwood, A Tagliabue… - Nature …, 2019 - nature.com
The dissolved iron supply controls half of the oceans' primary productivity. Resupply by the
remineralization of sinking particles, and subsequent vertical mixing, largely sustains this …

In situ particle measurements deemphasize the role of size in governing the sinking velocity of marine particles

JR Williams, SLC Giering - Geophysical Research Letters, 2022 - Wiley Online Library
Sinking particles are important in delivering carbon to the deep ocean where it may be
stored out of contact with the atmosphere. Whilst particle sinking velocities are known to be …

Investigating particle size-flux relationships and the biological pump across a range of plankton ecosystem states from coastal to oligotrophic

CK Fender, TB Kelly, L Guidi, MD Ohman… - Frontiers in Marine …, 2019 - frontiersin.org
Sinking particles transport organic carbon produced in the surface ocean to the ocean
interior, leading to net storage of atmospheric CO2 in the deep ocean. The rapid growth of in …
