Deployment of the CTD for nutrient samples and Be-7 work, getting the sampling sled ready for redeployment and deploying the sled., Retrieval of an Em-Apex float to reposition

The sampling sled was taken out of the water at 08:00 hours and the sea water samples were removed and tested using the G.C. SF6 tracer was discovered in measurable quantities ten meters above and below the 26 density level.

During the day CTD casts were made again for nutrient samples and for the Be-7 experiments.

At 18:00 we retrieved one of the EM-Apex floats to reprogram it and to adjust its position.

The sled was readied and redeployed at 21:00.
