StatusCompleted
Port of departureMombasa, Kenya
Port of returnDjibouti, Djibouti
PurposeResearch
ObjectivesThe objectives of this two-leg cruise were:
(a) To contribute to mapping the Somali Current and offshore eddies at its time of maximum development.
(b) To examine the vertical structure of the Somali Current and its relationship to sub-surface equatorial jets.
This leg of the cruise worked further XBT, CTD with rosette and profiling current meter sections off the Somalian coast. Further neutrally buoyant floats were deployed and tracked. Current meter moorings laid on the first leg were recovered and a further deployed FGGE telemetering buoy was deployed.
