ABSTRACT:
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 estimates.
