Limnological Conditions in Southern Lake Huron, 1974 and 1975

摘要

In 1974 and 1975, several studies were conducted on southern Lake Huron and outer Saginaw Bay to obtain seasonal data on limnological conditions. In 1974, 44 stations were sampled on each of eight cruises conducted from April to November. Each station was sampled at multiple depths so that more than 200 samples were taken on each cruise. Data obtained for each sample included water temperature, pH, specific conductance, chloride, total phosphorus, soluble reactive silica, nitrate plus nitrite nitrogen, ammonia nitrogen, chlorophyll a, and phaeopigments. In 1975, five special cruises were conducted. Four of these were used to compare phytoplankton productivity and nutrient dynamics in the frontal zone between highly enriched Saginaw Bay and the relatively low productivity waters of southern Lake Huron.
