PurposeResearch
ObjectivesThe main objective of this very short cruise was to deploy a novel moored observatory at PAP (NE Atlantic), a long term study site at which a variety of observations have been made over the past 20 years with increasing levels of intensity and sophistication. This new design was in collaboration with the UK Met Office.

In addition to this, a benthic lander was to be deployed which would transmit data by an acoustic link to the surface buoy and hence to land by satellite link.

A number of equipment trials were also carried out to good effect. In addition studies were made on the effects of high CO2 of calcifying phytoplankton. A team of photographers were present to in order to increase public awareness of observational oceanography and numerous interviews were completed. In addition a daily web diary was maintained by the EuroSITES outreach team.
