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 billion years. In the contemporary ocean, photosynthetic carbon fixation by marine phytoplankton leads to formation of approximately 45 gigatons of organic carbon per annum, of which 16 gigatons are exported to the ocean interior. Changes in the magnitude of total and export production can strongly influence atmospheric CO2… 
Biogeochemical Cycling of Carbon in Oceans and Climate Change
  • Environmental Science
C overing more than 70% of Earth, the world's oceans cycle carbon rapidly and exert strong, complex feedbacks on both contemporary geochemis-try and ongoing climate change. Understanding the global
Sensitivity of phytoplankton to future changes in ocean carbonate chemistry: current knowledge, contradictions and research directions
Despite their microscopic size, marine phytoplankton are responsible for about half of the global primary production and represent the basis of the marine food web. This diverse group of organisms
Oceanic sinks for atmospheric CO2
There is approximately 50 times more inorganic carbon in the global ocean than in the atmosphere. On time scales of decades to millions of years, the interaction between these two geophysical fluids

Changes in marine primary production over geological time have influenced a network of global biogeochemical cycles with corresponding feedbacks on climate. However, these changes continue to remain
Sinking Diatom Assemblages as a Key Driver for Deep Carbon and Silicon Export in the Scotia Sea (Southern Ocean)
Physical and biogeochemical processes in the Southern Ocean are fundamental for modulating global climate. In this context, a process-based understanding of how Antarctic diatoms control primary
Photosynthetic performance and productivity of phytoplankton in the Southern Ocean
Strong negative relationships between iron, temperature, and photoprotective pigments demonstrate that cells were producing more photoproctive pigments under low temperature and iron conditions, and are responsible for the low biomass and low productivity measured in the PFZ.
Climate-mediated changes to mixed-layer properties in the Southern Ocean : assessing the phytoplankton response
Abstract. Concurrent changes in ocean chemical and physical properties influence phytoplankton dynamics via alterations in carbonate chemistry, nutrient and trace metal inventories and upper ocean
Climate, carbon cycling, and deep-ocean ecosystems
Data from these two widely separated areas of the deep ocean provide compelling evidence that changes in climate can readily influence deep-sea processes, but the limited geographic coverage of these existing time-series studies stresses the importance of developing a more global effort to monitor deep-ocean ecosystems under modern conditions of rapidly changing climate.
Millennial-scale plankton regime shifts in the subtropical North Pacific Ocean
High-resolution records of changing plankton community composition in the North Pacific Ocean over the past millennium revealed three major plankton regimes corresponding to Northern Hemisphere climate periods, which are characterized by increasing production by dinitrogen-fixing cyanobacteria.
Compensation of ocean acidification effects in Arctic phytoplankton assemblages
The Arctic and subarctic shelf seas, which sustain large fisheries and contribute to global biogeochemical cycling, are particularly sensitive to ongoing ocean acidification (that is, decreasing


Evolution of the nitrogen cycle and its influence on the biological sequestration of CO2 in the ocean
Over geological time, photosynthetic carbon fixation in the oceans has exceeded respiratory oxidation of organic carbon. The imbalance between the two processes has resulted in the simultaneous
Large changes in oceanic nutrient inventories from glacial to interglacial periods
CHANGES in ocean chemistry and circulation have been invoked to explain the lower atmospheric CO2 concentrations of glacial periods observed in ice-core records1. The processes that modulate these
Effect of deep-sea sedimentary calcite preservation on atmospheric CO2 concentration
DURING the last glaciation, the atmospheric carbon dioxide concentration was about 30% less than the Holocene pre-industrial value1. Although this change is thought to originate in oceanic
Future ocean uptake of CO2: interaction between ocean circulation and biology
Abstract. We discuss the potential variations of the biological pump that can be expected from a change in the oceanic circulation in the ongoing global warming. The biogeochemical model is based on
Primary production of the biosphere: integrating terrestrial and oceanic components
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 carbon per year, with
Silicate regulation of new production in the equatorial Pacific upwelling
Surface waters of the eastern equatorial Pacific Ocean present the enigma of apparently high plant-nutrient concentrations but low phytoplankton biomass and productivity. One explanation for this
Simulated response of the ocean carbon cycle to anthropogenic climate warming
A 1995 report of the Intergovernmental Panel on Climate Change provides a set of illustrative anthropogenic CO2 emission models leading to stabilization of atmospheric CO2 concentrations ranging from

Three‐dimensional simulations of the impact of Southern Ocean nutrient depletion on atmospheric CO2 and ocean chemistry
Surface nutrient concentrations in the Southern Ocean are an important indicator of the atmosphere-ocean chemical balance that played a key role in ice-age reduction of atmospheric pC0, and would

Seven years of time-series observations of biogeochemical processes in the subtropical North Pacific Ocean gyre have revealed dramatic changes in the microbial community structure and in the
