Cruise description

This cruise went really well. We completed all the stations along Line P even though we had to modify the order towards the end of the Line to avoid some bad weather. We looked for an eddy on the return leg using the Moving Vessel Profiler (MVP) without success. We also surveyed the west coast of Vancouver Island over La Perouse Bank for a short time with the MVP. Unfortunately the instrument was lost at the end of the cruise while sailing in Juan de Fuca Strait.
We did not sample any of the Line R stations but accomplished all our planned work in Queen Charlotte Sound (SS Line), Rivers Inlet and Fitz Hugh Sound/Hakai Passage.
Vicki Fabry collected some pteropods that we delivered in Bamfield for a TV series led by the BBC (South Pacific in the UK, Wild Pacific in the US).
The sampling done during this cruise was performed using a CTD, a Rosette, a Bongo and a Live Reeve net..
