23h30: The alarm clock rings. I jump out of bed, boot up the computer and rush to the shower: a great way to wake up!

REMARKS: We are currently sampling one of two planned transects from shallow
(400m) to deep water (1200m) over the edge of the continental shelf. Last
night we ran the trawl-mounted still camera down the slope for two hours and
got some excellent images of the gradually changing sea-bed. We have also
trawled across the slope, at 400m, 800m and 1200m, to collect the animals
seen on the photographs, sampled the watercolumn with the CTD and, where the
sediment was suitable, collected sea-bed sediments. Yesterday we had two
failed trawls at 400m, one because the cod-end blew out, the other collected
a single very large rock which damaged the net. We are now returning to the
400m site for one last attempt before moving on to the next transect about
20 miles to the east. At about mid-day yesterday we met a fishing vessel
very close to our planned sampling sites. While manoeuvring to identify it
we acquired densely spaced depth data using the underway data logging
system. This was quickly manipulated by our Data Manager to produce a very
accurate bathymetric chart that proved to be very useful in deciding the
best line for running the transects.
Regards, Martin and Sarah.
