PurposeResearch
Objectives1. To provide a qualitative and quantitative description of the midwater and benthic ecosystems at a site on the Madeira Abyssal Plain (Great Meteor East).
2. To study the relationships between the midwater and benthic communities at GME.
3. To study the physical characteristics of the water column at GME.
4. To study the primary production of phytoplankton and its associated physico-chemical parameters both at GME and en-route to the site.
5. To make experimental observations on a range of oceanic animals both at GME and in transit.
