Porosity in sediment cores from the central Arctic Ocean during POLARSTERN cruise ARK-XXVII/3 from August-September 2012

During the RV Polarstern cruise ARK-XXVII/3 to the Arctic Ocean in summer 2012, when sea ice declined to a record minimum bottom, sediment cores were collected with a TV-guided multicorer at stations in the Nansen and Amundsen basin. For porosity measurements cores were subsampled and samples were stored at 4°C until analyzes in the home laboratory.

Chlorophyll pigments of the central Arctic Ocean during POLARSTERN cruise ARK-XXVII/3 from August-September 2012

During the RV Polarstern cruise ARK-XXVII/3 to the Arctic Ocean in summer 2012, when sea ice declined to a record minimum bottom, sediments were collected with a TV-guided multicorer at stations in the Nansen and Amundsen basin. Chlorophyll a and phaeopigments were extracted from sediments with acetone using three replicates per station. The concentrations in the acidified supernatants were measured with a Turner Trilogy fluorometer (Boetius and Damm, 1998). The sum of chlorophyll a and phaeopigments is expressed as chloroplast pigment equivalents (CPE) (Thiel, 1982).

Total dissolved organic carbon and total dissolved nitrogen in sediment pore water of the central Arctic Ocean collected during POLARSTERN cruise ARK-XXVII/3 from August-September 2012

During the RV Polarstern cruise ARK-XXVII/3 to the Arctic Ocean in summer 2012, when sea ice declined to a record minimum bottom, water and sediment pore water samples were collected with a TV-guided multicorer at stations in the Nansen and Amundsen basin. 50 ml sediment pore water samples were collected from 0-1, 1-5 and 5-10 cm sediment depths from up to 4 parallel sediment cores at each station. Additionally, overlying bottom waters were carefully collected from undisturbed sediment cores. Acidified pore water samples (pH2) were used for analysis of DOC and TDN concentrations. The measurements were performed by hand injection via catalytic oxidation at high temperature on a TOC-V Shimadzu instrument.

All Roads Lead to Rome: Background, Context and Legacy of the Treaty on the European Community. Jean Monnet/Robert Schuman Paper Series Special Issue 3, August 2012

From the Introduction. The rejection by the French National Assembly of the ill-fated European Defense Community (EDC) Treaty in August 30, 1954, together with the automatic shelving of the equally faulty European Political Community (EPC) proposal, put an end, at least for the time being, to any form of political and military union of the existing Western Europe on a supranational level. The times were difficult in Europe and the international atmosphere was cloudy. The end of the Korean War coincided with the insistence of the Soviets to stick to a policy of détente, leading to the suppression of the Hungarian rebellion. France was facing opposition to her colonial presence in Indochina, as well as in North Africa. But the crisis of Suez prompted the French government to distance itself from the British and the United States. The defeat of the EDC and EPC was not going to be the end of the story and the dream inaugurated by Monnet and Schuman in 1950. It was not long before plans in favor of a European re-launch were taking shape. 1
