Eastern Lake Superior Chemical and Physical Characteristics Data for 1968

摘要

Water samples at standard depths, bottom sediment and meteorological data were collected in Eastern Lake Superior at established stations in the course of seven lake cruises and four St. Marys River cruises during the 1968 open-water season. The sampling program and analytical methods are described. Chemical characteristics of the water and bottom sediment are listed by cruise for each station and sampling depth. Wind, wave, and sediment data are listed by cruise for each station. The statistical summaries showing lake-wide means, standard deviations and sample sizes of selected variables are presented by depth for each cruise period.
