Port of departureGlasgow, United Kingdom
Port of returnGlasgow, United Kingdom
PurposeResearch
ObjectivesThis cruise involves 19 research scientists from 7 European nations bringing together a very wide range of expertise including chemists, biologists, physicists and biogeochemical modellers. Many of these individuals are involved with the EU programme EuroBASIN. EuroBASIN is part of the trans-Atlantic BASIN initiative. This involves scientists from US, Canada and EU who are investigating how climatic and human activity affects the North Atlantic ecosystem.

The objective of the cruise is to use a wide variety of approaches to characterise the biological communities in the Euphotic and Twilight zones using water bottles, nets and video systems. We then characterise the chemical and physical environment and examine the sinking particles and the rate of downward flux of material using water samples, photographic approaches and the free drifting sediment trap PELAGRA.
