"Physical and chemical data were collected in Saginaw Bay, Lake Huron over the period 1991-1996 as part of a monitoring program to assess the ecological impact of the zebra mussel, Dreissena polymorpha. This report presents monitoring results for the years 1994-1996 and builds upon the previous technical memorandum GLERL-91 (ftp://ftp.glerl.noaa.gov/publications/tech_reports/glerl-091/) that described results for the years 1991-1993. Detailed accounts of sampling times, locations, and methods, and analytical procedures are included in each of the reports."--Page 5.
