Short caption: A geochemist degasses a pressure core in a temperature-controlled van during IODP Expedition 311. Long caption: Verena Heuer (Pressure Core Specialist/Organic Geochemist, University of Bremen) degasses a pressure core in a temperature-controlled (5°C) van during IODP Expedition 311. Degassing experiments on pressure cores provide estimates of in situ gas volumes. Gas samples (foreground) are also taken for shipboard chemical analyses and shore-based research. |
