Thanks to field volunteers Simon Beirne [also our intern for some of the time], David W. Chipman, Andy Ellis, Ed Friedman, Jim & Susan Gillies, Barry Goodman, Kathleen McGee, Dick Nickerson, Owen & Brandon Pierce, Leonard Skelton, Kermit Smyth, Bob Weggel, David Whittlesey, Elisa Vandervort, Tom Walling, Mary Earle Rogers, Odin Anderson, Peter & Noreen Ryan, Norman Anderson and Steve Dexter and for animation to Carey Phillips of Bowdoin College and Geno Carpentier of Woodlot Alternatives, later Stantec.

For acoustic doppler current profiling, thanks to the folks at the US Geologic Survey in Augusta: Bob Lent, Greg Stewart and especially field crew Laura Flight and Charlie Culbertson. Thanks also to Point of View Helicopter Services, Ben Magro of Coastal Helicopters for helping us out of a jam, Mike Chelminski of Stantec, Marinna Martini of USGS-Woods Hole, Peter Milholland & Friends of Casco Bay, and especially to Scott Allen of DeLorme for his troubleshooting and technical expertise.

Thanks also to our major funder: The Merrymeeting Bay Trust, to our sometime host; Chop Pt. School, to Hancock Lumber for donation of buoy materials and to Downeast Building Supply, DeLorme Mapping, and Tracker Radio Systems for discounts on various materials. Special thanks are due to David W. Chipman who performed extensive R&D on possible GPS units and means of extending their battery life in the field. David also researched battery types, designed the battery packs and machined the fixtures holding GPS and transmitter units. In addition, David has processed all of the data from 2005 and 2006 loggers prior to creation of final animations, which we contracted out to Woodlot Alternatives/Stantec.
