The ICE-CTD research cruise investigated cold water coral reefs and seawater properties around coral and non-coral areas. The objective was to characterise the present and past coral environmental conditions. Coral were sampled for dating, geochemical and genetic studies. The GIS Technician’s job mainly involved using ArcGIS to prepare the ROV dive routes and produce maps. They were also in charge of transferring the real-time data and comparing the real-time routes with the planned dive.
The ship left Brest on the 11th of June and headed straight to the Icelandic waters. It was initially planned to investigate the Logachev mound province but this was cancelled due to bad weather conditions. The ROV was deployed in three locations off southern Iceland and coral reefs were found in each area. Included are pictures from some of the spectacular locations discovered. The ship docked in Reykjavík for one night, allowing everyone to scramble off and explore Iceland’s beautiful scenery (geysers, icesheets, the mid-atlantic ridge, waterfalls!). The ROV team left the ship at Iceland and the rest of the team continued down the middle of the Atlantic to the Azores. CTD measurements were taken along the way and ARGOS floats were deployed, but it was a much quieter cruise on the way back.
