Nostalgia!

Stéphanie Pavoine. Based in Dumont D’Urville station

Hello. I am Stéphanie Pavoine. I am a fisheries engineer by training and I have just spent a year over-wintering at the Dumont D’Urville station.

Position of Aurora Australis

Sophie Mouge. Correspondent aboard the Aurora Australis

FROM: Martin Riddle
DATE: 05/01/08
REPORT (SITREP) NO.: 320
UNIVERSAL TIME: 0100
LOCAL (SHIP) TIME: 1200
AUSTRALIAN EASTERN STANDARD TIME: 1200
POSITION: -66 50S, 142 28E
HEADING: 340T
CURRENT SPEED (KNOTS): 2.5
DISTANCE TO NEXT WAYPOINT (NAUTICAL MILES): N/A
DISTANCE COVERED LAST 24 HOURS (NAUTICAL MILES): 105.9
WEATHER CONDITIONS: Clouds, moderate visibility, wind decreasing 14 kts from 125T with gusts to 16 kts
AIR TEMPERATURE: -1
SEA TEMPERATURE: -0.5
SEA CONDITIONS: Moderate seas from SE, moderate WNW swell 2-3 m
ICE CONDITIONS: Isolated bergs, occasional growlers and bergy bits, otherwise open water.
REMARKS: We completed sampling the main circuit of eastern CEAMARC benthic sites yesterday at about 2100 hrs last night and then returned to the Polynya moorings to move the Pole Compass. The Polyna moorings are measuring the speed and direction of water currents through the water column using Acoustic Doppler Current Profilers (ADCP), but at this distance from the South Magnetic Pole (only about 135 miles WNW of the moorings) normal compasses are not accurate. The Pole Compass is designed to give accurate readings even when very close to the magnetic pole and will be positioned alongside each of the ADCP Polynya moorings for a few days in order to allow correction of the data from their simpler onboard compasses. The Pole Compass was redeployed by about 0500 this morning and then CEAMARC sampling resumed with the first of four sites (400m, 800m, 1600m and 2400m) in a transect over the edge of the shelf break.
Regards, Martin and Sarah.
