Conference: ICES Deep-sea Symposium

May 21st, 2009  |  Published in Conferences

800px-azoren_141I recently participated in the ICES Deep-sea Symposium on the island of Faial in the Azores. This 4 day meeting ran from 27-30 April and included delegates from all over the world, presenting on subjects from mining to ecology of many deep-sea habitats.

The conference was headed: “Issues confronting the deep oceans: the economic, scientific and governance challenges and oppotuinites of working in the deep sea”. I was invited to present in a special session chaired by Jeff Ardron and Liz McLanahan entitled “Linking deep sea science to international decisions: Vulnerable and ecologically significant areas”.

My presentation was “Predicting the distribution of framework forming corals” and included updates on my new modelling processes and more importantly a new suite of environmental variables at a 30 arc second resolution (1 km). The presentation is available for viewing by clicking below. If you have any questions, or are interested in collaborating don’t hesitate to contact me.

Preserving deep-sea natural heritage: Emerging issues in offshore conservation and management

Dome-shaped colonies of Lophelia pertusaHuman activity in the deep sea is extending ever deeper, with recent research showing that this environment is more sensitive to human and natural impacts than previously thought. Some deep-water fish stocks have collapsed and fishing methods such as bottom trawling have raised international concern over the habitat damage they cause. It is likely that in its current form, deep-sea fishing is unsustainable. Diminishing reserves of hydrocarbons in shallow water are pushing exploration and production into deeper waters, which may cause damage to little known deep-sea habitats. The deep sea is also proposed as an environment where anthropogenic carbon dioxide could be stored to minimise the effect of its release into the atmosphere. At the same time, rising atmospheric carbon dioxide levels may be altering the chemical equilibrium of the global ocean by lowering pH. Many countries are now beginning to designate some deep-sea habitats as marine protected areas in measures to reduce the damage caused by fishing and other anthropogenic activities. This review examines these current and emerging issues in deep-sea conservation and discusses conservation status and the designation of protected areas. The enforcement of protected areas using satellite tracking of vessels is discussed and applied to an internationally agreed deep-water conservation area, which aims to protect cold-water coral habitats on the Darwin Mounds in the north east Atlantic Ocean.
