Abstract The winter of 2012 experienced peculiar atmospheric conditions that triggered a massive formation dense water on the continental shelf and in deep basin Gulf Lions. Multiplatforms observations enabled synoptic view spreading at scale. Five months after its formation, coastal origin created distinct bottom layer up to few hundreds meters thick over central part NW Mediterranean basin, which was overlaid by newly formed produced open‐sea convection. These new highlight role intense...

Abstract. The roles of iron and light in controlling biomass primary productivity are clearly established the Southern Ocean. However, their influence on net community production (NCP) carbon export remains to be quantified. To improve our understanding NCP Subantarctic Zone (SAZ) northern reaches Polar Frontal (PFZ), we conducted continuous onboard determinations as part Sub-Antarctic Sensitivity Environmental Change (SAZ-Sense) study, which occurred January–February 2007.

Abstract. The abundance and activity of the major members heterotrophic microbial community – from viruses to ciliates were studied along a longitudinal transect across Mediterranean Sea in summer 2008. is characterized by west to-east gradient deepening DCM (deep chlorophyll maximum) increasing oligotrophy reflected gradients biomass production. However, within this well documented trend, hydrological mesoscale features exist likely influence dynamics. Here we present data W-E 17 stations...

Abstract. The long-term monitoring of basic hydrological parameters (temperature and salinity), collected as time series with adequate temporal resolution (i.e. a sampling interval allowing the all important timescales) in key places Mediterranean Sea (straits channels, zones dense water formation, deep parts basins), constitute priority context global changes. This led CIESM (The Science Commission) to support, since 2002, HYDROCHANGES programme...

Abstract One pathway by which the oceans influence climate is via emission of sea spray that may subsequently cloud properties. Sea emissions are known to be dependent on atmospheric and oceanic physicochemical parameters, but potential role ocean biology fluxes remains poorly characterized. Here we show a consistent significant relationship between seawater nanophytoplankton cell abundances sea-spray derived Cloud Condensation Nuclei (CCN) number fluxes, generated using water from three...

Abstract In the eastern Mediterranean Sea, satellites have observed events of spring surface‐chlorophyll increase in Rhodes Gyre region recurring intermittently. Few situ biogeochemical data, however, exist to confirm their consistency, elucidate seasonal characteristics, or discriminate among possible drivers. During year 2018, an array BGC‐Argo floats was deployed region, collecting first‐ever annual time series profiles parameters this area. Their observations demonstrated that nitrates,...

Abstract. Total alkalinity (AT) and dissolved inorganic carbon (CT) in the oceans are important properties with respect to understanding ocean cycle its link global change (ocean sinks sources, acidification) ultimately finding carbon-based solutions or mitigation procedures (marine removal). We present a database of more than 44 400 AT CT observations along basic ancillary data (spatiotemporal location, depth, temperature salinity) from various regions obtained, mainly framework French...

Abstract. Although the Southern Ocean is considered a high-nutrient, low-chlorophyll (HNLC) area, massive and recurrent blooms are observed over downstream of Kerguelen Plateau. This mosaic triggered by higher iron supply resulting from interaction between Antarctic Circumpolar Current local bathymetry. Net primary production, N uptake (NO3− NH4+), nitrification rates were measured at eight stations in austral spring 2011 (October–November) during KEOPS 2 cruise Plateau area. Natural...

Iron (Fe) is an essential micronutrient for phytoplankton growth, but its scarcity in seawater limits primary productivity across much of the ocean. Most dissolved Fe (DFe) complexed with Fe-binding organic ligands, a poorly constrained fraction matter (DOM), which increase residence time and impact bioavailability. Here, we present conditional concentration (L ) binding-strength (log <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"...
