Operational support for HabcamV4 on scallop surveys and post-cruise data processing

Abstract

The use of underwater stereo imagery in stock assessment and ecosystem analysis is becoming wide spread as an alternative to pelagic and benthic trawling. We have been collaborating with NOAA for the past six years in developing new, non-invasive technologies for cost effectively surveying sea scallops and ground fish. As such we have developed a stereo optical and acoustic imaging system that is currently being used by NOAA to survey scallops along the entire northeast continental shelf. This proposal is in support of four WHOI/NOAA initiatives that directly relate to either further development of this technology or to its application in enhancing stock assessment of sea scallops and ground fish. Project Tasks: 1) WHOI’s participation in the annual 2015 and 2016 scallop surveys and post cruise data processing, 2) WHOI’s participation in the development of habitat characterization methods and data products using data from HabCamV4, 3) Support for development and testing of image processing and machine vision tools for segmentation and classification of yellowtail flounder and other difficult targets (in collaboration with Lakshman Prasad, Los Alamos National Laboratory), 4) Support for Peter Honig for developing machine vision tools for classifying substrate, scallops, and other targets.
