Multistate Aquatic Resources Information System (MARIS)

MARIS is an internet-based information sharing network that allows multiple states to provide a common set of variables via a single web interface. MARIS is not a ?dataset? but rather links specific content of multiple states? datasets. MARIS does not capture all of the information from a state?s aquatic dataset ? only a subset of data collected as part of aquatic species sampling surveys. The MARIS structure was developed by a consortium of state fish and wildlife agencies and implemented through contracts with various universities. Federal agency partners have provided the core funding for developing and implementing MARIS as well as broad guidance on the content of the system.
