Information    
Welcome to the beta version of the MEMO website. MEMO is the result of a collaboration fostered by the Aquatic Sensor Workgroup of the National Water Quality Monitoring Council's Methods and Data Comparability Board.

With funding from EPA's Advanced Monitoring Initiative and NOAA's IOOS Program, MEMO is designed to bring together information from NOAA's Alliance for Coastal Technology (ACT) and the National Environmental Methods Index (NEMI).

The ACT Technology Database is a continuously updated catalogue of instrumentation used for coastal and ocean science and observations, designed to help you identify technologies available to meet your specific needs. Search by environmental parameters, sensor types or manufacturers.

NEMI is an online clearinghouse of environmental monitoring methods. The NEMI database contains chemical, micro-biological and radiochemical method summaries of lab and field protocols for regulatory and non-regulatory water quality analyses.
