Compilation of downward flux observations from sediment trap deployments in the Atlantic Ocean - Contribution to EURO-BASIN's Data integration, supplement to: Torres-Valdés, Sinhue; Painter, Stuart; Martin, Adrian Peter; Sanders, Richard J; Felden, Janine (2014): Data compilation of fluxes of sedimenting material from sediment traps in the Atlantic Ocean. Earth System Science Data, 6, 123-145

Sinhue Torres-Valdés, Adrian Peter Martin, Stuart Painter & Richard J Sanders
We provide a compilation of downward fluxes (total mass, POC, PON, BSiO2, CaCO3, PIC and lithogenic/terrigenous fluxes) from over 6000 sediment trap measurements distributed in the Atlantic Ocean, from 30 degree North to 49 degree South, and covering the period 1982-2011. Data from the Mediterranean Sea are also included. Data were compiled from different sources: data repositories (BCO-DMO, PANGAEA), time series sites (BATS, CARIACO), published scientific papers and/or personal communications from PI's. All sources are...

The synergistic effects of increasing temperature and CO2 levels on activity capacity and acid-base balance in the spider crab, Hyas araneus

Zora M C Zittier, Timo Hirse & Hans-Otto Pörtner
In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Lavigne and Gattuso, 2011) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI). The date of carbonate chemistry calculation by seacarb is 2013-10-26.

Seawater carbonate chemistry and physiological response of the Mediterranean crustose coralline alga Lithophyllum cabiochae to elevated pCO2 and temperature, supplement to: Martin, Sophie; Cohu, Stéphanie; Vignot, Céline; Zimmerman, Guillaume; Gattuso, Jean-Pierre (2013): One-year experiment on the physiological response of the Mediterranean crustose coralline alga, Lithophyllum cabiochae, to elevated pCO2 and temperature. Ecology and Evolution, 3(3), 676-693

Sophie Martin, Stéphanie Cohu, Céline Vignot, Guillaume Zimmerman & Jean-Pierre Gattuso
The response of respiration, photosynthesis, and calcification to elevated pCO2 and temperature was investigated in isolation and in combination in the Mediterranean crustose coralline alga Lithophyllum cabiochae. Algae were maintained in aquaria during 1 year at near-ambient conditions of irradiance, at ambient or elevated temperature (+3 °C), and at ambient (ca. 400 µatm) or elevated pCO2 (ca. 700 µatm). Respiration, photosynthesis, and net calcification showed a strong seasonal pattern following the seasonal variations of temperature...

Physiological and ecological variables measured at the high and low pCO2 reef sections, supplement to: Fabricius, Katharina Elisabeth; Langdon, Chris; Uthicke, Sven; Humphrey, Craig; Noonan, Sam; De'ath, Glenn; Okazaki, Remy; Muehllehner, Nancy; Glas, Martin S; Lough, Janice M (2011): Losers and winners in coral reefs acclimatized to elevated carbon dioxide concentrations. Nature Climate Change, 1(3), 165-169

Experiments have shown that ocean acidification due to rising atmospheric carbon dioxide concentrations has deleterious effects on the performance of many marine organisms. However, few empirical or modelling studies have addressed the long-term consequences of ocean acidification for marine ecosystems. Here we show that as pH declines from 8.1 to 7.8 (the change expected if atmospheric carbon dioxide concentrations increase from 390 to 750 ppm, consistent with some scenarios for the end of this century)...

Profile of sediment echo sounding during POLARSTERN cruise ARK-VIII/3 with links to ParaSound graphic files

Dieter K Fütterer
The Parasound profile of cruise ARK-VIII/3 were originally recorded on 7 paper rolls. Each roll was digitized using a scanner "Océ CS 4044 Colour System" by SAGA GmbH (http://www.digitalarchivieren.de). Resulting 7 files are stored in tif-format with a resolution of 200 dpi and were zipped to reduce its size by about 30%.
