Diatoms sustain the marine food web and contribute to the export of carbon from the surface
ocean to depth. They account for about 40% of marine primary productivity and particulate …

Twenty years ago, measurements on ice cores showed that the concentration of carbon
dioxide in the atmosphere was lower during ice ages than it is today. As yet, there is no …

The Southern Ocean plays a critical role in regulating global climate as a major sink for
atmospheric carbon dioxide (CO2), and in global ocean biogeochemistry by supplying …

PISCES-v2 is a biogeochemical model which simulates the lower trophic levels of marine
ecosystem (phytoplankton, microzooplankton and mesozooplankton) and the …

Diatoms account for up to 40% of marine primary production, and require silicic acid to grow
and build their opal shell. On the physiological and ecological level, diatoms are thought to …

Residual macronutrients in the surface Southern Ocean result from restricted biological
utilization, caused by low wintertime irradiance, cold temperatures, and insufficient …

Diatoms are the world's largest contributors to biosilicification and are one of the
predominant contributors to global carbon fixation. Silicon is a major limiting nutrient for …

The ocean's biological carbon pump is a key component of the global carbon cycle. Only a
small fraction of the carbon fixed by primary production is exported to the deep ocean, yet …

Diatoms are a major component of phytoplankton community. They tend to dominate under
natural high-nutrient concentrations, as well as during artificial Fe fertilisation experiments …

A global three‐dimensional marine ecosystem model with several key phytoplankton
functional groups, multiple limiting nutrients, explicit iron cycling, and a mineral …
