First night on board!

Sophie Mouge. Correspondent aboard the Aurora Australis

Weird deep noises sometimes invade our surroundings on board: we look at each other questioningly, asking ourselves what could be happening. But we quickly figure out that we can’t tell because of our unfamiliarity with the ship! Only the crew can know.

Position of Aurora Australis

Sophie Mouge. Correspondent aboard the Aurora Australis

FROM: Martin Riddle
DATE: 17/12/08
REPORT (SITREP) NO.: 301
UNIVERSAL TIME: 0100
LOCAL (SHIP) TIME: 1200
AUSTRALIAN EASTERN STANDARD TIME: 1200
POSITION: -44 40, 145 35
HEADING: 187
CURRENT SPEED (KNOTS): 1.5
DISTANCE TO NEXT WAYPOINT (NAUTICAL MILES): 1.5
DISTANCE COVERED LAST 24 HOURS (NAUTICAL MILES): 189
WEATHER CONDITIONS: sunny breaks, wind 10 kts from 200T
AIR TEMPERATURE: 11.4
SEA TEMPERATURE: 13.4
SEA CONDITIONS: 3 m SW swell with 1 m SW sea
ICE CONDITIONS: nil
REMARKS: Everyone is settling in well with most appearing for breakfast or at least lunch. The swell last night was enough to remind everyone to stow things securely. We are currently laying out the PULSE mooring - a trial surface mooring, which if successful will become the design model for future moorings fitted with sediment traps to collect sinking particulate matter. The mooring is now streaming for about 2 kilometres behind the ship ready to be deployed in the next hour. The three hour delay in departure yesterday to continue working on the Acoustic Doppler Current Profiler (ADCP) was well worthwhile, the ADCP is running well and giving good data to depths of up to 500-700m. Our thanks to everyone at the AAD, particularly SAO and Macquarie Wharf, for helping us get away well prepared for the scientific work ahead and to the P&O crew involved in the dry-docking and fast turnaround.
Regards, Martin and Sarah.
