Position of Aurora Australis

Sophie Mouge. Correspondent aboard the Aurora Australis

FROM: Martin Riddle
DATE: 18/01/08
REPORT (SITREP) NO.: 333
UNIVERSAL TIME: 0100
LOCAL (SHIP) TIME: 1200
AUSTRALIAN EASTERN STANDARD TIME: 1200
POSITION: -65 39.7, 140 32.8
HEADING: Various
CURRENT SPEED (KNOTS): 2 kts
DISTANCE TO NEXT WAYPOINT (NAUTICAL MILES): n/a
DISTANCE COVERED LAST 24 HOURS (NAUTICAL MILES): 102.3 Nm
WEATHER CONDITIONS: Partly cloudy, otherwise fine and sunny, good visibility, wind 7 kts from 60T
AIR TEMPERATURE: 1.0
SEA TEMPERATURE: 1.0
SEA CONDITIONS: Slight seas and moderate WNW swell 3-4 m
ICE CONDITIONS: Scattered grounded bergs including one very large berg (~35km long) to the NNE, otherwise open water.
REMARKS: We are now sampling the second of the transects into deep water over the edge of the continental shelf. This one is down the path of what appears to be a drainage canyon based on detailed multi-beam imagery. The sea-bed here is very rugged and the sampling is particularly difficult - which is the reason why it was left to the end of the CEAMARC phase of the voyage. There is too much risk of damaging the gear for us to have attempted it earlier. However, the deck crew have done an excellent job of deploying the equipment over very difficult terrain and we have been rewarded with superb imagery and samples. We are again seeing many of the species that previously were only found in the 'coral garden' reported down a similar slope in the western sector. Here the diversity appears to be somewhat greater as it is not so completely dominated by a few very abundant species. We had contact with a second fishing vessel yesterday afternoon, owned by the same company as the one seen a day ago.
Regards, Martin and Sarah.

Parade of stars on the Aurora Australis

Sophie Mouge. Correspondent aboard the Aurora Australis

The popping flashes echo from a distance. Passing before the door to the wet lab, we are blinded by the dazzling and constant bolts of light that filter through the little window. The rumor that has been flying for a bit is finally confirmed: the stars are among us!

Final operations!

Stéphanie Pavoine. Based in Dumont D’Urville station

Thomas wakes me at 8h to do another filtration shift. The ship is moving slowly because of the Tubai. It pitches a lot. I finish my shift for better or worse, my stomach lurching.
