Comments

We are now sampling the second of the transects into deep water over the edge of the continental shelf. This one is down the path of what appears to be a drainage canyon based on detailed multi-beam imagery. The sea-bed here is very rugged and the sampling is particularly difficult - which is the reason why it was left to the end of the CEAMARC phase of the voyage. There is too much risk of damaging the gear for us to have attempted it earlier. However, the deck crew have done an excellent job of deploying the equipment over very difficult terrain and we have been rewarded with superb imagery and samples. We are again seeing many of the species that previously were only found in the 'coral garden' reported down a similar slope in the western sector. Here the diversity appears to be somewhat greater as it is not so completely dominated by a few very abundant species. We had contact with a second fishing vessel yesterday afternoon, owned by the same company as the one seen a day ago. Regards, Martin and Sarah.
