Glass half full

During the night the Hamcam (the camera attached to the Hamon grab) unfortunately failed so no images could be recorded as the grab hits the seabed and takes a sample. However, by changing the block used to winch the hamon grab we were still able to tell when we hit the bottom and so grabbing continued, as did the camera tows  on the sledge.

In a sandy sediment grab sample we found this biroworm (Hyalinoecia tubicola), which builds a glass-like tube for protection and to live in.

Glass more than half full - biroworm Hyalinoecia tubicola
