In search of lost materiel!

Stéphanie Pavoine. Based in Dumont D’Urville station

Morning on the Lion with Thomas, near the ICOTA containers. We are waiting for Anne and Pierre who still have not shown up. Thomas goes for news while I finish arranging two or three things.

How beautiful it is "down under"!

Sophie Mouge. Correspondent aboard the Aurora Australis

The last trawls of the first part of the CEAMARC program were put in the water last weekend.The trawl that was towed at 800 meters came back up so full that the net tore just as it was about to be hauled up on the trawl deck.

Position of Aurora Australis

Sophie Mouge. Correspondent aboard the Aurora Australis

FROM: Martin Riddle
DATE: 07/01/08
REPORT (SITREP) NO.: 322
UNIVERSAL TIME: 0100
LOCAL (SHIP) TIME: 1200
AUSTRALIAN EASTERN STANDARD TIME: 1200
POSITION: -65 56S, 143 21E
HEADING: 001T
CURRENT SPEED (KNOTS): 13 Kts
DISTANCE TO NEXT WAYPOINT (NAUTICAL MILES): n/a
DISTANCE COVERED LAST 24 HOURS (NAUTICAL MILES): 127.6 Nm
WEATHER CONDITIONS: Mostly cloudy, good visibility, wind 12 kts from 180T
AIR TEMPERATURE: -0.3
SEA TEMPERATURE: 0.8
SEA CONDITIONS: Slight seas, low NE'ly swell 1m
ICE CONDITIONS: Open water.
REMARKS: We are now well into the main CASO (Climate of the Antarctic and Southern Ocean) leg of the voyage. We will spend 6.3 days (oceanographers can be very precise) using the CTD to sample the water column from 31 sites in a large loop that will take us about 150 Nm northwards from the shelf break and then east for a similar distance before heading south again to return to the shelf break. At our current location the water is about 3600 m deep and each CTD cast is taking about two and half hours. During this circuit we will sample three canyon systems discovered using multi-beam sea-bed imagery obtained by US and Italian survey vessels. These canyons are thought to drain the cold dense Antarctic bottom water formed in the Mertz Polynya.
Regards, Martin and Sarah.
