PurposeResearch
ObjectivesFRidge – GA13 GEOTRACES Section.
Mobilisation for JC156 (GEOTRACES section GA13) commenced on the 15th of December 2017 and was completed in time for an on time departure on the morning of the 20th of December 2017. Our cruise track took us out into the English Channel and west towards the continental shelf break and the Bay of Biscay. We first conducted some test stations off Biscay and then sailed south towards the Iberian Peninsula for a cross over station with the French GEOTRACES GA01 cruise off Portugal. Following this we celebrated Christmas as we sailed west towards the Azores plateau. After sailing north of the Azores islands we turned southward and began tracking along the mid Atlantic ridge. On the 3rd of January we came alongside at Ponte Delgado in the Azores to collect an additional technician. Following science stations along the mid Atlantic ridge we sailed for port at Guadeloupe and arrived on the morning of the 1st of February 2018. Demobilisation was rapid as we had packed and cleaned during the steam to port.
