The last work is going on in the wet lab. The scientists have spent a total of three weeks sampling specimens brought up from the Southern Ocean.

REMARKS: After finishing the CEAMARC survey at midnight a day and a half ago
we steamed to the start of a series of 12 CASO CTD water sampling sites in a
transect from the edge of the continental shelf northwards into the Southern
Ocean. At the time of writing we are sampling the last but one of these,
with the final samples to be collected at latitude 63 21S this evening from
just below the sea surface to just above the seabed at a depth of 3812m. If
the Aurora Australis were a large orange hot-air balloon flying over Hobart
at this height above sea-level and attempting to sample the air down to the
surface of Constitution Dock it would be floating at three times the height
of Mt Wellington (1270m).
