Description:
Water quality in Saginaw Bay, Michigan (western Lake Huron) was surveyed during 32 cruises in 1974 and 1975, as part of the International Joint Commission's Upper Lakes Reference Study co-sponsored by the United States and Canada. Goals of the study were to establish a base of water quality information and to provide data required to model biological and hydrological processes in the bay. Sampling and in situ monitoring were conducted at 18-day intervals during April - October (coinciding with Landsat satellite passes) and approximately at monthly intervals during November - March. Samples were collected from several depth levels at 59 stations in 1974 and at 37-station subset of these 59 stations in 1975. Measurements included: temperature, dissolved oxygen, conductivity, chloride, pH alkalinity, Secchi depth, chlorophylls, nitrate and phosphate, organic nitrogen, total phosphorus, organic carbon, total solids and major metals. Additional diurnal or daily sampling was conducted at selected stations.
