In 1987, this view provided the basis for the hypothesis of a feedback between oceanic phytoplankton and … This "Cited by" count includes citations to the following articles in Scholar.

    He has also studied the biophysical controls on ocean productivity and export production, and the importance of the nitrogen and iron cycles in ocean biogeochemistry. His research has also drawn in geoengineering, astrobiology, and the evolution of groups including phytoplankton and … We interpret the environmental controls on the global ocean diazotroph biogeography in the context of a three global model of MFD which combines a three‐dimensional ocean circulation model (MITgcm; Marshall et al.) with biogeochemical and ecological we find here that nutrient resource availability is the primary control.

Biogeochemical reactions can ultimately development of sharp gradients at the water-sediment control phosphate availability to primary producers, with a interface, where in a very narrow sediment horizon, oxic to negative feedback loop between sediment and macroalgae, yet anoxic gradients can establish, which promote coupled potentially regulating growth rates and shifts within the bacterial

    CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): 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 1-1-2011 · What ocean biogeochemical models can tell us about bottom-up control of ecosystem variability. – ICES Journal of Marine Science, 68: 1030–1044. Processes included in earth system models amplify the impact of climate variability on phytoplankton biomass and, therefore, on upper trophic levels.

Fronts act to increase production by channeling nutrients through multiple trophic levels, including commercially important fishes and marine mammals, and enhance carbon export to the deep ocean. Fronts

    ability in Arctic primary production can be explained by two key physical factors: (i) the maximum penetration of winter mixing, which determines the amount of nutrients available for summer primary production, and (ii) short-wave radia-tion at the ocean surface, which controls the magnitude of phytoplankton blooms.

This study examines the role of iron as a buffer of pore water sulfide and its implications for marine organic

    1-2-2011 · During eutrophication, biogeochemical feedbacks further increase the supply of N and P, but decrease availability of silica – conditions that can favor the formation and persistence of harmful algal blooms. Given sufficient N inputs, estuaries and coastal marine ecosystems can be driven to P limitation. Microbial processes are responsible for most reactions involved in the nitrogen cycle in the oceans, which determine the fluxes of this crucial nutrient in these environments. The present review provides an overview of the contribution of anaerobic ammonium oxidation (Anammox) to marine biogeochemical …
