First night at sea!

Patrice Pruvost. Correspondent aboard the Umitaka Maru

Our first night at sea went well. We rounded the cape at the far southwest end of Australia. During the night, the wind was against us.

Consolidating the data from the campaign

Sophie Mouge. Correspondent aboard the Aurora Australis

Our last night was a very short one. The party was a real success. We went to bed late (or early, depending on the person!). The ocean swells invited themselves and were particularly strong, which kept us from sleeping soundly.

Position of Aurora Australis

Sophie Mouge. Correspondent aboard the Aurora Australis

FROM: Martin Riddle
DATE: 24/01/08
REPORT (SITREP) NO.: 339
UNIVERSAL TIME: 0100
LOCAL (SHIP) TIME: 1200
AUSTRALIAN EASTERN STANDARD TIME: 1200
POSITION: -52 25.3, 143 26.4
HEADING: 044T
CURRENT SPEED (KNOTS): 13.0 kts
DISTANCE TO NEXT WAYPOINT (NAUTICAL MILES): 466
DISTANCE COVERED LAST 24 HOURS (NAUTICAL MILES): 247.3
WEATHER CONDITIONS: Mostly cloudy, with sunny intervals, fine, good visibility, winds 25 kts from 270T gusting to 30 kts
AIR TEMPERATURE: 7.5
SEA TEMPERATURE: 7.6
SEA CONDITIONS: Rough seas and heavy W'ly swell 4m
ICE CONDITIONS: Nil
REMARKS: The heavy swell caused a bit of motion in the ship last night and the vessel course is being adjusted slightly to minimise discomfort while still making good speed. Although most of the scientific sampling is now complete, some will continue until we steam up the Derwent. The CO2 group are still measuring pCO2 in surface waters and the atmosphere, are taking 6 hourly underway samples for 02, CO2, salinity, nutrients and oxygen isotopes and are continuing to analyse CTD samples previously collected. The phytoplankton group are continuing with underway sampling of surface water from the seawater line 2 to 4 times per day to assess phytoplankton productivity. Most on board are continuing to process samples, collate data or prepare preliminary reports. Last night the ship's company was treated to a soiree-style entertainment featuring many of the very talented musicians and performers on board. Our thanks go to all involved for making it a very special occasion.
Regards, Martin and Sarah.
