HLY-04-04 Video Plankton Recorder (VPR) Data [Ashjian, C.]



Data were collected on cruise HLY0404 to the Chukchi and Beaufort Seas on the U.S. Coast Guard Cutter (USCGC) Healy from 2 September 2004 to 1 October 2004 as part of the Shelf Basin Interactions program. The primary sampling instrument was a self-contained, battery powered, single camera Auto Video Plankton Recorder (AutoVPR; SeaScan, Inc.) that was deployed from the stern of the ship in a stainless-steel cage. The AutoVPR records video image frames from a Pulnix TM7 CCD camera at 720 x 640 pixels at 30 Hz as a wavelet compressed data stream together with coincident data from a SeaBird SBE49 Conductivity Temperature Depth (CTD) operating at 10Hz.
