The Surface Ocean CO2 Atlas (SOCAT) is an effort by the international marine carbon research community. It aims to improve access to surface water fugacity of carbon dioxide (fCO2, similar to partial pressure) by regular releases of quality controlled and fully documented synthesis and gridded fCO2 products. SOCAT version 2 presented here extends the data set for the global oceans and coastal seas by 4 years and has 10.1 million surface water fCO2 data from 2660 cruises between 1968 and 2011. The procedures for creating version 2 have been similar to those for version 1. The SOCAT website (http://www.socat.info) provides...
Radionuclides measured on water bottle samples during SONNE cruise SO202 (INOPEX) - Hayes, Christoper T; Anderson, Robert F; Jaccard, Samuel L; Francois, Roger; Fleisher, Martin Q; Soon, Maureen; Gersonde, Rainer
Boundary scavenging, or the enhanced removal of adsorption-prone elements from the ocean in areas of high particle flux, is an often cited, though not well-quantified, concept used to understand the oceanic distribution of many trace metals. Because 230Th and 231Pa are produced uniformly from uranium decay and removed differentially by scavenging, the process of boundary scavenging can be elucidated by a more detailed knowledge of their water column distributions. To this end, filtered seawater was collected across the gradients in particle flux which span the subarctic Pacific: in the west during the Innovative North Pacific Experiment (INOPEX) and in the...
Chlorophyll a concentration and zooplankton abundance and biomass below melting sea ice in the Amundsen Gulf - Hop, Haakon; Mundy, Christopher J; Gosselin, Michel; Rossnagel, Andrea L; Barber, David G
Early summer in the Arctic with extensive ice melt and break-up represents a dramatic change for sympagic-pelagic fauna below seasonal sea ice. As part of the International Polar Year-Circumpolar Flaw Lead system study (IPY-CFL), this investigation quantified zooplankton in the meltwater layer below landfast ice and remaining ice fauna below melting ice during June (2008) in Franklin Bay and Darnley Bay, Amundsen Gulf, Canada. The ice was in a state of advanced melt, with fully developed melt ponds. Intense melting resulted in a 0.3- to 0.5-m-thick meltwater layer below the ice, with a strong halocline to the Arctic water below....
Stareso MedSeA mesocosm experiment: field and perturbation studies 2012 - Gazeau, Frédéric; Taillandier, Vincent; Alliouane, Samir
A joint mesocosm experiment took place in June/July 2012 in Corsica (bay of Calvi, Stareso station;http://www.stareso.com/) as part of the european MedSeA project. Nine mesocosms (52 m**3) were deployed over a 20 days period and 6 different levels of pCO2 and 3 control mesocosms (about 450 µatm), were used, in order to cover the range of pCO2 anticipated for the end of the present century. During this experiment, the potential effects of these perturbations on chemistry, planktonic community composition and dynamics including: eucaryotic and prokaryotic species composition, primary production, nutrient and carbon utilization, calcification, diazotrophic nitrogen fixation, organic matter exudation...
