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.

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.
