We added the capability to directly observe zooplankton distributions to an autonomous profiling mooring by installing a camera system, essentially an underwater microscope with a lower size limit of 100 microns, images approximately 1 liter of water 5 times per second. The image is scanned for plankton and other particulates by automated software, and assigned to different taxonomic and functional categories. By profiling the camera every day, we will be able to observe the cycle of secondary production in central PWS at much finer scales than have ever been done before, and produce an operational measurement of zooplankton abundance that may be used by fishery managers for planning and decision making. This dataset is composed of 16 bit TIFF files captured by the camera system. Please see the included README file (1502_images_readme.txt) for details on image capture, directory structure, and file-naming conventions.
