Marine microalgae sequester as much CO2 into carbohydrates as terrestrial plants.
Polymeric carbohydrates (ie, glycans) provide carbon for heterotrophic organisms and …

Global estimates indicate the oceans are responsible for approximately half of the carbon
dioxide fixed on Earth. Organisms⩽ 5 μm in size dominate open ocean phytoplankton …

Extensive studies in the 1980s–1990s led to the characterization of latitudinal variations in
sea surface δ13C values of particulate organic carbon (δ13CPOC), and relationships were …

Members of the prokaryotic picoplankton are the main drivers of the biogeochemical cycles
over large areas of the world's oceans. In order to ascertain changes in picoplankton …

Despite similar physical properties, the Northern and Southern Atlantic subtropical gyres
have different biogeochemical regimes. The Northern subtropical gyre, which is subject to …

We have developed a model linking phytoplankton absorption to phytoplankton size classes
(PSCs) that uses a single variable, the optical absorption by phytoplankton at 443 nm, aph …

The phytoplankton pigment composition (chlorophylls and carotenoids) from 17 Atlantic
Meridional Transect (AMT) cruises over the period 1995–2005 was analysed to determine …

Recent measurements of surface coccolithophore calcification from the Atlantic Ocean (50°
N–50° S) are compared to similar measurements from other oceanic settings. By combining …

Coccolithophore species composition was determined in 199 samples collected from the
upper 300 m of the Atlantic Ocean, spanning temperate, tropical and subtropical waters in …

The detrainment of organic matter from the mixed layer, a process known as the mixed layer
pump (ML pump), has long been overlooked in carbon export budgets. Recently, the ML …
