The Workshop on Great Lakes
acoustic standard operating procedures (SOP) was held 8-11 September at the
Michigan Department of Natural Resources (MI DNR), Charlevoix Fishery Research Station.
The workshop was paid for by a $10,500 grant received from the Great Lakes
Fishery Commission (GLFC) science transfer fund, with participants charged a small
fee of $50 each to offset costs of provided meals. The workshop included 1) introductory
lectures on fishery acoustics, 2) description of the new Great Lakes acoustic SOP,
3) instruction on the use of two acoustic post processing software packages (Echoview 4.5 and Sonar 5), 4) demonstration of methods for
conducting field calibration tests aboard the MI DNR research vessel Steelhead,
5) an example application of the SOP to a Lake Champlain data set, and 6) instruction
on cluster analysis, geostatistics and uncertainty
analysis. A total of 69 people were invited to participate, but the actual
number of participants was 26 led by 5 instructors. Scientists from 3
Universities, 2 private-sector businesses, 10 state, federal and provincial
agencies and 1 private environmental consultant attended. The workshop provided
an opportunity for new acoustic users to network with more experienced users
within the framework of describing how to apply the SOP. A workshop exit survey showed attendees were generally
pleased with the workshop. Future acoustic workshops should be directed towards
case studies using the new SOP, invertebrate sampling and bottom typing
applications, and methods of incorporating all uncertainty in confidence bound
