    "title": "Physical, chemical, and biological water quality data and CTD casts collected from NOAA R\/V Shenehon in Saginaw Bay, Lake Huron in the Great Lakes region from 1991-04-12 to 1996-09-20 (NCEI Accession 0218895)",
    "description": "This dataset includes physical and chemical data collected in Saginaw Bay, Lake Huron from 1991 to 1996. All of these data were collected as part of a larger effort to monitor and assess the impacts of the zebra mussel (Dreissena polymorpha) on the Saginaw Bay ecosystem. Although mussels were found in the bay in 1990, the first large recruitment did not occur until the summer of 1991. Thus, the data presented herein reflect physical and chemical conditions, and subsequent changes, during the initial years of the mussel\u2019s invasion into the bay.",
