Role of zooplankton dynamics for Southern Ocean phytoplankton biomass and global biogeochemical cycles

Publikováno v: Biogeosciences, Vol 13, Iss 14, Pp 4111-4133 (2016)

Global ocean biogeochemistry models currently employed in climate change projections use highly simplified representations of pelagic food webs. These food webs do not necessarily include critical pathways by which ecosystems interact with ocean biog

High-resolution analysis of a North Sea phytoplankton community structure based on in situ flow cytometry observations and potential implication for remote sensing

Autor: M. Thyssen, S. Alvain, A. Lefèbvre, D. Dessailly, M. Rijkeboer, N. Guiselin, V. Creach, L.-F. Artigas

Publikováno v: Biogeosciences, Vol 12, Iss 13, Pp 4051-4066 (2015)

Phytoplankton observation in the ocean can be a challenge in oceanography. Accurate estimations of its biomass and dynamics will help to understand ocean ecosystems and refine global climate models. Relevant data sets of phytoplankton defined at a fu

Phytoplankton competition during the spring bloom in four plankton functional type models

Autor: T. Hashioka, M. Vogt, Y. Yamanaka, C. Le Quéré, E. T. Buitenhuis, M. N. Aita, S. Alvain, L. Bopp, T. Hirata, I. Lima, S. Sailley, S. C. Doney

Publikováno v: Biogeosciences, Vol 10, Iss 11, Pp 6833-6850 (2013)

We investigated the mechanisms of phytoplankton competition during the spring bloom, one of the most dramatic seasonal events in lower-trophic-level ecosystems, in four state-of-the-art plankton functional type (PFT) models: PISCES, NEMURO, PlankTOM5

Large-scale shifts in phytoplankton groups in the Equatorial Pacific during ENSO cycles

Autor: I. Masotti, C. Moulin, S. Alvain, L. Bopp, A. Tagliabue, D. Antoine

Publikováno v: Biogeosciences, Vol 8, Iss 3, Pp 539-550 (2011)

The El Niño Southern Oscillation (ENSO) drives important changes in the marine productivity of the Equatorial Pacific, in particular during major El Niño/La Niña transitions. Changes in environmental conditions associated with these climatic event

Spatial and temporal variability of the dimethylsulfide to chlorophyll ratio in the surface ocean: an assessment based on phytoplankton group dominance determined from space

Autor: I. Masotti, S. Belviso, S. Alvain, J. E. Johnson, T. S. Bates, P. D. Tortell, N. Kasamatsu, M. Mongin, C. A. Marandino, E. S. Saltzman, C. Moulin

Publikováno v: Biogeosciences, Vol 7, Iss 10, Pp 3215-3237 (2010)

Dimethylsulfoniopropionate (DMSP) is produced in surface seawater by phytoplankton. Phytoplankton culture experiments have shown that nanoeucaryotes (NANO) display much higher mean DMSP-to-Carbon or DMSP-to-Chlorophyll (Chl) ratios than Prochlorococc

Evaluation of the global oceanic isoprene source and its impacts on marine organic carbon aerosol

Autor: S. R. Arnold, D. V. Spracklen, J. Williams, N. Yassaa, J. Sciare, B. Bonsang, V. Gros, I. Peeken, A. C. Lewis, S. Alvain, C. Moulin

Publikováno v: Atmospheric Chemistry and Physics, Vol 9, Iss 4, Pp 1253-1262 (2009)

We have combined the first satellite maps of the global distribution of phytoplankton functional type and new measurements of phytoplankton-specific isoprene productivities, with available remote marine isoprene observations and a global model, to ev
