Processes and patterns of oceanic nutrient limitation
Microbial activity is a fundamental component of oceanic nutrient cycles. Photosynthetic microbes, collectively termed phytoplankton, are responsible for the vast majority of primary production inExpand
Enhanced biological carbon consumption in a high CO2 ocean
The oceans have absorbed nearly half of the fossil-fuel carbon dioxide (CO2) emitted into the atmosphere since pre-industrial times, causing a measurable reduction in seawater pH and carbonateExpand
Declining oxygen in the global ocean and coastal waters
Beneath the waves, oxygen disappears As plastic waste pollutes the oceans and fish stocks decline, unseen below the surface another problem grows: deoxygenation. Breitburg et al. review the evidenceExpand
Future ocean acidification will be amplified by hypoxia in coastal habitats
Ocean acidification is elicited by anthropogenic carbon dioxide emissions and resulting oceanic uptake of excess CO2 and might constitute an abiotic stressor powerful enough to alter marine ecosystemExpand
Impacts of Atmospheric Anthropogenic Nitrogen on the Open Ocean
Increasing quantities of atmospheric anthropogenic fixed nitrogen entering the open ocean could account for up to about a third of the ocean's external (nonrecycled) nitrogen supply and up to ∼3% ofExpand
Eddy-induced enhancement of primary production in a model of the North Atlantic Ocean
In steady state, the export of photosynthetically fixed organic matter to the deep ocean has to be balanced by an upward flux of nutrients into the euphotic zone. Indirect geochemical estimates ofExpand
Future changes in climate, ocean circulation, ecosystems, and biogeochemical cycling simulated for a business-as-usual CO2 emission scenario until year 4000 AD
A new model of global climate, ocean circulation, ecosystems, and biogeochemical cycling, including a fully coupled carbon cycle, is presented and evaluated. The model is consistent with multipleExpand
Simultaneous data-based optimization of a 1D-ecosystem model at three locations in the North Atlantic: Part I— Method and parameter estimates
An optimization experiment is performed with a vertically resolved, nitrogen-based ecosystem model, composed of four state variables (NPZD-model): dissolved inorganic nitrogen (N), phytoplankton (P),Expand
Sensitivities of marine carbon fluxes to ocean change
Throughout Earth's history, the oceans have played a dominant role in the climate system through the storage and transport of heat and the exchange of water and climate-relevant gases with theExpand
Nitrogen cycling driven by organic matter export in the South Pacific oxygen minimum zone
Oxygen minimum zones are expanding globally, and at present account for around 20–40% of oceanic nitrogen loss. Heterotrophic denitrification and anammox—anaerobic ammonium oxidation with nitrite—areExpand
