The CCAMLR krill synoptic survey

Station positions for 4 ships

The station positions for 4 ships have been calculated in a QuattroPro spreadsheets to allow the calculation of distance and steaming times for different plans. The actual provisional positions are now available. In addition the Waypoints for Ship 1, Waypoints for Ship 2 ,  Waypoints for Ship 3 and Waypoints for Ship 4 are finally available

At present there is an overall cruise track plot which shows how the interleaving transects will be arranged. The station plot below is calculated on the assumption that each ship stops at midnight and midday to undertake an RMT and a CTD. Two hours have been allowed for each daytime station. The time allocated to the nighttime stations vary according to the length of darkness; this depends on the position and date. Daylight times are provided here. The speed between stations on the north/south transects is 10.5 knots. On the transect heads the ships do not stop to sample and the speed has been increased to 12 knots. On the present plan the green ship (UK) carries out 34 stations, the red ship (USA) carries out 36 stations  in the survey, the black ship (Japan) carries out 35.

During the meso-scale surveys (USA and Japan) acoustic transects will be steamed using the same protocol as the large scale sampling ie the ship will not survey during the night but will stop during the day for a 2 hour net sampling period around local midnight. NB this is a significant change to the previous version of the website. The Waypoints and Station Positions are being recalculated at present and can be recognized by bearing an October date at the foot of the relevant pages.
