  4. Tuesday 17 June • Soccer: • 1) France-Italy • 2) The Netherlands – Romania • Action points: • Frans Jorissen and Yves-Marie to provide samples to the partner in Münster for analysis. • Cleaning issues should be clarified. • Shauna to provide “organic lining” of Amphistegina (composed of Bayerite: Al(OH)3) to the partner in Münster both isolated as well as normal (fossil) shells • Inorganic pttn samples of Gernot (different states of transformation of vaterite to calcite) should be analysed by Frédéric for Mg isotopes • Next annual meeting to be held in Angers, June 16/17 2008 • Culture working group meeting Juli 6, 2007

  5. Paleosalt; where are we and what’s new? • Who does what in „PaleoSalt“? • Status WP 1 Jelle Bijma (AWI, Bremerhaven) PaleoSalt annual meeting, Angers June 16-17 2007

  6. 1) Develop a mechanistic understanding for the d18O-Mg/Ca based salinity proxy 2) Develop an independent salinity proxy based on the dD of organic compounds (and combine 1) and 2) into an additional, d18Ow and dDw independent salinity estimate) 3) Develop an independent salinity proxy based on variations of the elemental and isotopic ratios, incorporated into biogenic calcite PaleoSalt

  7. WP1: Salinity effects on proxy incorporation in foraminifera • Inorganic precipitation experiments (baseline) • Task 1.1: The impact of the carbonate chemistry on salinity proxies in benthic foraminifera. • Task 1.2: Experimental studies on the impact of the carbonate chemistry on salinity proxies in planktonic foraminifera. • Task 1.3: Experimental studies on the impact of salinity on the dD of specific compounds. • Task 1.4: Numerical small scale process modelling

  8. WP1: Salinity effects on proxy incorporation in foraminifera • Inorganic precipitation experiments: Gernot Nehrke (EuroMinScI: „BioCalc“) • Culture experiments: • benthonic foraminifera: Delphine Dissard (DFG/NWO Paleoprox) • planktic foraminifera: Régine da Rocha (EuroCLIMATE: PaleoSalt) • coccolithophorids: Albert Benthien, Karolin Schreiber, Ingrid Zondervan • Calcification mechanisms at cellular level: Ingrid Zondervan (NEBROC) • Small scale process modelling: Christof Meile (HWK fellowship) Mg incorpo-ration into porcelaneous foraminifera (e.g. Pyrgo) Mg incorpo-ration intoradial forami-nifera (e.g. all planktics and most benthonics)
