Quality assurance and auditing manual data

Quality Assurance and Auditing manual data

  • Concerns addressed:

    • outliers

    • misidentifications

    • inaccurate measures

    • scallop false positives, negatives

    • differences between annotators

    • detection of unforeseen issues


Rsa 2011 qaqc tasks

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


Qaqc example

Habitat mapping camera system

HabCam (towed underwater camera system):

Enhances our knowledge about the scallop resource and helps us contribute to management decisions


Habitat mapping camera system

  • 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

  • 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.
