HLY-04-02 Video Plankton Recorder (VPR) Data [Ashjian, C.]


Data were collected on cruise HLY0402 to the Chukchi and Beaufort Seas on the U.S. Coast Guard Cutter (USCGC) Healy from May 16, 2004 to June 23, 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.
