26,322 Ft.: OSIL Giant Piston Corer Breaks Deep-Ocean Sampling Record Ocean Scientific International report that one of its Giant Piston Corer systems has broken two records in scientific ocean drilling and coring on the International Ocean Discovery Program (IODP) Expedition 386. The expedition has been staged by the European Consortium for Ocean Research Drilling (ECORD) to gain an insight into the seismic history of the study region off the Japanese coast, and is supported by the Japan Agency for Marine-Earth Science and Technology (Jamstec). On Friday May 14, 2021, the team on board the RV Kaimei recorded an historic sampling water depth of 8,023m (26,322 ft.), and recovered a 37.74m core in a 40m barrel string, a 94.3% recovery rate and record deepest sub-sea level sample (from 8060.74 metres below sea level) from the Giant Piston Corer that was produced, installed and supported by OSIL.
