The system was tested using the ADF&G research vessel Pandalus in June 2006 and again in June 2007 using a new and improved sled. During these cruises, 1.1 million images were captured over a track 550 km long at depths of 40-140 meters. Performance of the GE1380C was excellent; the 1360x1024 pixel sensor provided resolution greater than 1 pixel/mm on the bottom, which enabled identification of objects smaller than 50mm in most water conditions. ADF&G researchers are excited by prospects for cutting-edge science using this new tool. Although the sled system was developed for scallop stock assessment surveys, it appears to be useful for other fishery research applications such as fine-scale habitat mapping, ground-truthing of acoustic data, benthic ecology research, and fishing gear effects studies.
