For the period from January to September 1991 we describe spatial and temporal variations of sea surface carbon dioxide fugacity (fCO 2 ) in Antarctic, Subantarctic, subtropical, tropical regions Indian Ocean (including Red Sea). The measurements were made continuously with an infrared technique during seven cruises. We study fCO at daily, monthly seasonal scales selected areas. High‐frequency variabilities 20 μatm/d have been observed near polar frontal zone. Both are large subtropical...
Abstract. A large part of the Pacific Arctic basin experiences ice-free conditions in summer as a result sea ice cover steadily decreasing over last decades. To evaluate impact retreat on ecosystem, we investigated phytoplankton communities from coastal sites (Chukchi shelf) to northern deep basins (up 86° N), during year 2008 high melting. Pigment and taxonomy situ data were acquired under different regime: -free (IFB, 74°–77° marginal zone (MIZ, 77°–80° N) heavy covered (HIB, >80° N)....
Seamounts are ecological oases nurturing abundant fisheries resources and epibenthic megafauna in the vast oligotrophic ocean. Despite their significance, formation mechanisms underlying these seamount remain uncertain. To shed light on this phenomenon, study conducted interdisciplinary situ observations focusing a shallow The findings show that seamount's topography interferes with oceanic current to generate lee waves, effectively enhancing nutrient supply euphotic layer downstream of...
A new method to transform satellite ocean color data into estimates of primary production and carbon fluxes is presented. one‐dimensional coupled physical‐bio‐geochemical model the surface constrained reproduce seasonal evolution chlorophyll concentration by adjusting parameters 10‐compartment trophic system using a variational technique. The applied in situ from station Papa, but averaged over characteristic depth measurements, affected errors compatible with those values. Using 35...

Abstract. A drastic ice decline in the Arctic Ocean, triggered by global warming, could generate rapid changes upper ocean layers. The retreat is particularly intense over Canadian Basin where large free areas were observed since 2007. CHINARE 2008 expedition was conducted Western (WA) during a year of exceptional (August–September 2008). This study investigates whether significant reorganization primary producers terms species, biomass and productivity has to be WA as result melting. Both...
