EXBODI / The engines of marine biodiversity
30 September 2011
End of the Exbodi cruise, 26 days at sea, New Caledonian EEZ, the Loyauté Ridge, and the southern slope of the South Province, number of stations = 172; explored depths: between 250 and 1150 m. One lost dredge! Collections: about 500 specimens of fish, about 2700 cnidarians; about 78 lots of ...
EXBODI / Many thanks to the ship's crew
29 September 2011
Without the seamen of the Alis, our research cruises would simply not be possible! We are a small scientific team, and we depend on their know-how to successfully sample benthic fauna in the South Pacific. On the bridge, Raymond, Jean-François, and Julien keep us on the right track, help the ...
EXBODI / Cruise material and collection
28 September 2011
The samples collected during oceanographic cruises are tomorrow's collections. This tomorrow can be very close as molecular studies, for example, require an immediate and long-lasting traceability of the study material. The point is not to preserve the original sample associated to a sequence ...
EXBODI / A «sea» of Brachiopods
27 September 2011
Among the strange creatures encountered during this oceanographic cruise, we need to talk about the great abundance of Brachiopods in some banks of the New Caledonian EEZ. Brachiopods nowadays are a very discreet group. Most of the species live attached to hard substrates by one of their two ...
The past of oceans told by sponges and corals
25 September 2011
Although our main objectives are to explore the New Caledonia deep-sea biodiversity and to better understand the biogeography of the fauna, our trawls bring back a large variety of samples that can be of interest to our chemist, geologist, and paleoceanographer colleagues like Kate Hendry (Woods ...
The archaic fauna from New Caledonia
21 September 2011
Our trawls sometimes contain strange organisms, with an ‘out of this world’ morphology. These unusual shapes can be considered as relicts of a long-gone time. Indeed, some very similar creatures were only known in fossil fauna from the Secondary Era (-150 to -65 million years) and were therefore ...
EXBODI / The brittlestar and the gorgonian
18 September 2011
We very often collect organisms that live in association in our trawls. Gorgonians, in particular are often associated with numerous benthic animals. In the Southeastern part of the New Caledonian EEZ, we very often find brittlestars (echinoderms related to starfish) that cling to gorgonian ...
EXBODI / an underwater Jurassic Park
14 September 2011
After a day of work on the Durand Bank, we are heading south towards an unnamed bank that we will later christen Jurassic Park as it brought us some good surprises. We conducted a series of collections between 200 and 800 m depth on the Eastern flank of this bank. After a promising start, ...
Exbodi continues... leg 2
13 September 2011
After 48 hours a the dock in Noumea (11-12 September), during which the scientific team changed, the Exbodi cruise continues in the waters of New Caledonia. The second leg will take place from September 13th through October 1st 2011, and will mainly explore the seamounts of the Loyautés Ridge ...
EXBODI / Last day of work before the switch of scientific teams
10 September 2011
For this last day, our work takes place off the Sarcelle waterway where we spotted a seamount with a flat top as shallow as 400 m. Around this structure, le bottom is relatively flat and the depth is about 800 m. We bring back a large quantity of relatively large sponges, as well as a nice ...
