| Gravity corer is being recovered using special support frame |  |
| Gravity corer in support frame on deck RV Meteor |  |
| sediment samples for methane analysis are taken from the core catcher directly after recovery |  |
| 3 ml of sample are filled into prepared 50 ml glass vial containing 20 ml of 1.2M NaCl / 0.3M HgCl2 solution. Vials are sealed immediately and methane analysis is performed on board using headspace GC |  |
| core liner is pulled out of gravity core steel housing tube and cut into 1m segments on deck. After the liner is cut the sediment is cut using a string. |  |
| Segments are sealed with yellow lids and labeled immediately after separation |  |
|
core segments are brought into geolab and labeled (work and archive halves, core number, core depth upper and lower end of segment) |
 |
| the empty part of the uppermost core segment is cut |  |
| Core segments are transferred into cool lab for sampling |
