The ECORD Science Operator (ESO) is a consortium of European scientific institutions formed to undertake mission-specific platform (MSP) expeditions for ECORD on behalf of the Integrated Ocean Drilling Program (2003-2013) and the International Ocean Discovery Program launched in October 2013. ESO comprises the British Geological Survey (BGS), the MARUM, University of Bremen and the European Petrophysics Consortium (EPC). BGS acts as consortium coordinator responsible for overall ESO management under a contract from EMA as designated by the ECORD Council. The EPC is contracted to carry out logging and petrophysical activities. The University of Bremen is contracted to carry out curation and data management tasks.

To date, ESO has completed seven MSP operations, 4 expeditions from 2003-2013 and 3 expeditions since 2013. ESO is completing Expedition 381 to the Gulf of Corinth, Greece, (end of March 2018). Two MSP expeditions to the polar regions are planned to be operated beyond 2018 (see below MSP schedule).

ESO Tasks

  • As an Implementing Organization for MSPs, ESO has the task of operational and scientific planning; engineering development, platform and equipment procurement; contracting; essential training of personnel; safety surveys; data management; core curation; onshore science parties (OSP); publications; outreach and other related pre-, intra- and post-operational activities.
  • ESO also undertakes the staffing of MSP science parties in consultation with USSSP, J-DESC and ESSAC.
  • It is ESO’s responsibility to ensure that MSPs comply with international and national regulations and obligations.
  • ESO provides facilities and staff to ensure the maintenance of capability in science operations for ECORD on a year-by-year basis.

To date, ESO has completed seven scientific expeditions of mission-specific platforms (MSPs). Four expeditions in the first phase of IODP (2003 to 2012), which are Exp 302 Arctic Coring (ACEX), Exp 310 Tahiti Sea-Level, Exp 313 New Jersey Shallow Shelf and Exp 325 Great Barrier Reef Environmental Changes. Three expeditions in the second phase of IODP (2013-2023), which are Exp 347 Baltic Sea Paleoenvironment, Exp 357 Atlantis Massif Serpentinization and Life Expedition, Exp 364 Chicxulub K-Pg Impact Crater Expedition and the offshore phase of the Exp 381 Corinth Active Rift Development Expedition.

ESO is preparing the Onshore Science Party of Expedition 381 to start on 4 February 2018, and scoping of MSP expeditions to the polar regions, in the Arctic (Exp 377) and in the Antarctic (Exp 373).
