Objectives | The main objective of this very short cruise was to refurbish the PAP observatory (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.
In addition to this a small number of other observations were made and samples collected. In order to increase public awareness of observational oceanography film interviews were carried out and a daily web diary maintained. Celtic Explorer slipped her moorings exactly on schedule and proceeded to the PAP site at about 10knots in moderate seas. During the entire occupation of the site the weather remained good and no time was lost to this. During the 2 .5 days at the site, almost all of the objectives were met with considerable success and we left the site with a major new mooring deployed and sending some of the data back in real time to NOC. This will be recovered in September 2008. In addition, a sediment trap was successfully recovered, all traps having worked perfectly since July 2006 and a replacement mooring was deployed. A Bathysnap time lapse benthic camera system was successfully deployed but the only major failure was to recover the Bathysnap deployed at the site in July 2006. | ||||||||||||||||||||||||||||||||||||||||||||||||||||
