  4. HabCam History: Development (2002-2005) • 2002-2003: • Idea from industry and R&D work with WHOI. • Award from Northeast Consortium of Sea Grant Institutions. • 2004: • HabCam I tested on R/V Oceanus. • 2005: • HabCam II becomes operational.

  5. HabCam History: Research (2006-2008) • HabCam versionII (currently funded by Scallop RSA): • 2006 - Five trips June-October. Two parts of NLSCA, SE Part CLAII, GB HAPC, CLAI. • 2007 - Four trips July-August. 100 joint tows with R/V Albatross IV during dredge survey in ET, GB HAPC, CLAI, and WGSC. • Started joint dredge tow program with NOAA. • 2008 - Joint tows in ET, DMV with the F/V Kathy Marie and the R/V Albatross IV. AST vehicle used for simultaneous optical and acoustic data in SBNMS, Jeffreys Ledge, CLAI, CLAII HAPC, WGSC HAPC.

  6. HabCam History: Research (2009-current) • 2009: 3 RSA trips Jun.-Jul. 56 comparative tows with the R/V Hugh R. Sharp in MAB and GB scallop resource areas comparing dredge catch rates. Optical surveys conducted in NLSCLA, CLAI, WGSC HAPC. • 2010 - 2 RSA trips Jul.-Aug. CLAII, western side of the WGSC; Start of NOAA Project Phase I • 2011 – 1 RSA trip CLAI and NOAA Survey Leg 3 • 2012 – 1 RSA trip CLAII and all of NOAA Survey

  7. 2008 Joint Tows: Relative dredge efficiency and variability in multiple scallop resource areas.

  8. 2008 Joint Tows: Relative dredge efficiency and variability in multiple scallop resource areas Elephant Trunk 44 joint tows 3 -7 passes DelMarVa 7 joint tows 3 passes

  9. 2009 Joint Tows: NMFS Scallop Survey Leg II - NLSCA

  10. 2009 Joint ship Tows on NMFS Scallop Survey Leg II - NLSCA R/V Hugh Sharp WGSC, CLAI, CLAII, Canadian Side Nantucket Lightship Scallop Access Area Area: 334 nm2 Trackline length: 348 nm Images Collected: 1,235,251 Images Processed: 123,000 Area Covered: 0.187 nm2 % Area Covered: 0.54 % Time to collect data: 70h, 2.9 days Time to process data: 7 days x 2 = 14 days Survey Efficiency: 334/20 = 17 nm2/day

  11. Nantucket Lightship Scallop Access Area

  12. 2010: RSA Grid Survey SE Part GB

  13. RSA Grid Survey - August 2010 * 880 km (475 nm) total * 4.5 days to complete @ 5 kts * 1,760,000 usable images * Manual analysis every 10th image ~170,000 images processed 112 person hours * Automated analysis every image 6 images/sec 8 hours

  14. 2010 RSA Survey: Scallop Density 18 / m2 Closed Area II Scallop Access Area

  15. 2010 RSA Survey: Scallops and Yellowtail Flounder Yellowtail Closed Area II Scallop Access Area

  16. 2011: RSA Grid Survey CLAI

  17. 2011 NMFS Scallop Survey (Leg III)

  18. 2012: RSA Grid Survey • CLAII Scallop Access Area • HAPC • 2012 Scallop Survey (all Legs)

  19. Manual annotation tool for measuring and classifying scallops and other targets

  20. Side scan sonar data provides a unique view of what the Seafloor looks like in relation to the images from HabCam 50 m

  21. Quality Assurance and Auditing manual data • Concerns addressed: • outliers • misidentifications • inaccurate measures • scallop false positives, negatives • differences between annotators • detection of unforeseen issues

  22. RSA 2011 QAQC tasks • Review any notes or flags annotators had placed on images. • Review images from the tails of the scallop histogram • Select images at random from the entire dataset • Review of all fish identifications Fish category counts

  23. QAQC EXAMPLE

  24. HabCam (towed underwater camera system): Enhances our knowledge about the scallop resource and helps us contribute to management decisions

  25. For use in sea scallop stock and habitat assessment, the HabCam System collects simultaneous: • high resolution imagery • latitude, longitude • temperature, salinity, chlorophyll • acoustic side scan backscatter • other environmental and sensor data • The HabCam Group: • Arnies Fisheries Inc. • Captain and Crew of the F/V Kathy Marie • Woods Hole Oceanographic Institution • Engineers and Scientists • Independent Researchers

  27. The Northeast Consortium (since 1999) • An organization of New England Sea Grant cooperative programs: • University of Maine • University of New Hampshire • Massachusetts Institute of Technology • Woods Hole Oceanographic Institution • Four objectives: • 1. Develop partnerships between commercial fishermen and scientists, educators, and coastal managers; • Enable participation in collaborative research by commercial fishermen and commercial fishing vessels; • 3. Help bring fishermen's information into the scientific framework needed for fisheries management; • 4. Utilize commercial vessels as research/monitoring platforms. • * Since its nearly 200 projects have been funded by the Consortium.

  28. HabCam: Origin: A cooperative program through the Northeast Consortium Now funded through the Scallop Research Set-Aside Program by participating commercial scallop fishing vessels • The HabCam Group: • Arnies Fisheries Inc. • Captain and Crew of the F/V Kathy Marie • Woods Hole Oceanographic Institution • Engineers and Scientists • Independent Researchers More information: http://habcam.whoi.edu/
