Narrative

The Endeavour sailed Thursday 00:00 and headed for the West Gabbard where the SmartBuoy was deployed, a CTD cast for water and ring nets (200um x 2) were collected We then steamed to the Warp collecting surface water en-route. The SmartBuoy was serviced and water samples collected before and after for calibration.

Leaving the Thames via the Princes Channel we went round into the Channel to service Waveriders but the wind and sea picked up. It became obvious we would not be able to complete any work at Dungeness or Hastings, so we turned around at 19:30 and steamed back north towards the Sean Gas Field. We stopped at the "Mid Site" and Southern Bight for CTDs and were still collecting hourly surface stations for nutrients and salinity.

We arrived at the Sean Gas Field site and collected a full set of CTD water samples and ring nets. The guard buoy was recovered easily but the lander, although responding as released, did not pop up the recovery floats. We spent 3 hours towing a grapple to hook it manually but without success. It is possible that the wire was snagged once but subsequently parted. The guard buoy was re-laid but not a new lander. It was too rough to attempt using the bent
