Changes in oceanic primary production, linked to changes in the network of global
biogeochemical cycles, have profoundly influenced the geochemistry of Earth for over 3 …

Integrating conceptually similar models of the growth of marine and terrestrial primary
producers yielded an estimated global net primary production (NPP) of 104.9 petagrams of …

The temperature of seawater can affect marine plankton in various ways, including by
affecting rates of metabolic processes. This can change the way carbon and nutrients are …

Biological processes in the oceans play a crucial role in regulating the fluxes of many
important elements such as carbon, nitrogen, sulfur, oxygen, phosphorus, and silicon. As we …

Photosynthesis fixes carbon into organic matter in the ocean. Biological forces then paint
intricate flux patterns for carbon in ocean space and in time, as it flows through the food web …

Ocean biogeochemical and ecosystem processes are linked by net primary production
(NPP) in the ocean's surface layer, where inorganic carbon is fixed by photosynthetic …

The future impacts of anthropogenic global change on marine ecosystems are highly
uncertain, but insights can be gained from past intervals of high atmospheric carbon dioxide …

Food-web processes are important controls of oceanic biogenic carbon flux and ocean-
atmosphere carbon dioxide exchange. Two key controlling parameters are the growth …

Climate change, rising atmospheric carbon dioxide, excess nutrient inputs, and pollution in
its many forms are fundamentally altering the chemistry of the ocean, often on a global scale …

Iron is an essential nutrient that regulates productivity in~ 30% of the ocean. Compared with
deep (> 2000 meter) hydrothermal activity at mid-ocean ridges that provide iron to the …
