Appendix A — Station Classifications

This information was compiled as part of a larger system-wide effort to combine the many factors that influence coastal water quality using the Coastal and Marine Ecological Standard (CMECS) Classifications. For more information on the NERRS Characteristics of Land Use and Ecosystems (CLUE) project, visit https://www.nerra.org/swmp-clue/.

Table A.1: Coastal and Marine Ecological Standard CMECS Classifications for the four GTM Research Reserve long-term water quality monitoring stations, Pine Island gtmpiwq, San Sebastian gtmsswq, Fort Matanzas gtmfmwq, and Pellicer Creek gtmpcwq.

Station Description NO land cover The Guana Tolomato Matanzas Fort Matanzas station is a fixed near-bottom water quality station (GTMFMWQ) in a Channel surrounded by Non-Tidal Scrub-Shrub. The station is located within a Moderately Tidal, high salinity Lagoonal Estuary. The Guana Tolomato Matanzas Pellicer Creek station is a fixed near-bottom water quality station (GTMPCWQ) in a Channel surrounded by Emergent Wetland. The station is located within a Moderately Tidal, brackish Riverine Estuary. The Guana Tolomato Matanzas Pine Island station is a fixed near-bottom water quality station (GTMPIWQ) in a Channel surrounded by Emergent Wetland. The station is located within a Moderately Tidal, high salinity Lagoonal Estuary. The Guana Tolomato Matanzas San Sebastian station is a fixed near-bottom water quality station (GTMSSWQ) in a Channel surrounded by Emergent Wetland. The station is located within a Moderately Tidal, high salinity Lagoonal Estuary.
