Position of Aurora Australis

Sophie Mouge. Correspondent aboard the Aurora Australis

FROM: Martin Riddle
DATE: 21/01/08
REPORT (SITREP) NO.: 336
UNIVERSAL TIME: 0100
LOCAL (SHIP) TIME: 1200
AUSTRALIAN EASTERN STANDARD TIME: 1200
POSITION: -63 52, 139 52.6
HEADING: 080T
CURRENT SPEED (KNOTS): 0 kts
DISTANCE TO NEXT WAYPOINT (NAUTICAL MILES): n/a
DISTANCE COVERED LAST 24 HOURS (NAUTICAL MILES): 96.1 Nm
WEATHER CONDITIONS: In fog, poor visibility to less than 0.5 nm, light winds 8 kts from 295T
AIR TEMPERATURE: 1.6
SEA TEMPERATURE: 1.3
SEA CONDITIONS: Slight seas and moderate W'ly swell to 2-3m
ICE CONDITIONS: Nil, Open water.
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).
Regards, Martin and Sarah.
