ECOgaps Cruise

The aim of the ECOgaps cruise was to improve our knowledgebase of the region's biological, chemical, and physical properties for the management of the King Haakon VII Sea from the coast of the Dronning Maud Land as part of CCAMLR's WSMPA Domain 4 planning. The focus of this cruise was on Astrid Ridge and Maud Rise. Work was divided into 7 packages:


1) Bird and marine mammal observations

2) Fish community

3) Benthic mapping

4) Zooplankton

5) Primary Production

6) Oceanography

7) Ocean Carbon chemistry.

This is merely the preliminary cruise report with general impressions and initial observations and results.

Statement

Data for all 7 packages were collected over the course of the cruise:


1) Manned lookout while ship was moving and recorded all bird and marine mammals observations


2) Continuously ran multibeam echo sounder for bottom profiles for krill and the mesopelagic layer when the ship was moving; Trawled and sampled for species and size distribution when echo sounder indicated swarm of krill; Fish trawls; Bottom sampling gear (RP sled, beam trawl, bottom trawl); Longline


3) Deployed 12 hour ROV transect with grab samples and continuous video recording; Bottom sampling gear (RP sled, beam trawl, bottom trawl)


4) Continuously ran multibeam echo sounder for bottom profiles for krill and the mesopelagic layer when the ship was moving; Trawled and sampled for species and size distribution when echo sounder indicated swarm of krill: Sampled from 3 CTD stations; Krill trawls; Multinet tows; Bottom sampling gear (RP sled, beam trawl, bottom trawl)


5) Sampled 3 CTD stations


6) Continuously ran ADCP for currents throughout the water column when the ship was moving; Sampled 3 CTD stations


7) Continuously ran multibeam echo sounder for pCO2 when the ship was moving; Sampled 3 CTD stations
