Cefas Endeavour - 24/7 survey work.

The "snow" is sediment in the water column that reflects the light from the lights on the camera frame as it flies past the camera

Looks like snow but is in fact sediment at 100m below the surface of the sea at the North of Celtic Deep in St George's Channel where the Cefas Endeavour is currently on station undergoing her MCZ Characterisation Survey 2012. 


The blog makes interesting reading this trip as there are two teams aboard the boat, the second being the JNCC Offshore survey team with their own blog to follow - the seagoing research blog wars are hotting up!
