Bottom Photographs:

In April of 2003, scientists from the U.S. Geological Survey used the Florida Institute of Oceanography's research vessel Suncoaster to collect bottom photographs, video images, and bottom samples from Pulley Ridge (location map). The instrument used to collect these data was the SeaBOSS (Seabed Observation and Sampling System) developed at the USGS Woods Hole Science Center (Blackwood and Parolski, 2001). This instrument incorporates two video cameras, a still camera, pressure-depth sensor, modified Van Veen grab sampler, several types of lights, and lasers used for scale measurements and ranging.

More information about the SeaBOSS acquisition system can be obtained from the technology page of the USGS Woods Hole Science Center (http://woodshole.er.usgs.gov/).

The still images were initially recorded by the SeaBOSS system onto a large roll of film that can contain approximately 250 images. These rolls of film were subsequently sent to the Two Cat Digital company (http://www.twocatdigital.com/index.html) in California to be converted to digital images. This company digitized the images to a PCD multi-resolution format and wrote the images to CD-ROM. A maximum of 100 images were written to each CD. The CDs were each given a unique number, and the images written to the CDs were given a standard name format starting with IMG0001 and continuing until the last image on the CD (IMG0100). This report archives one resolution of each image (1536 x 1024) in JPEG image format.

This report is intended to archive these digital JPEG images. These still-photo images can be perused starting from the Image Catalogs page. The photos are organized based on the SeaBOSS dive (deployment) number. Alternatively, the images can be downloaded directly from disc based on CD number/image number.
