Severn Riverkeeper Water Quality Monitoring Projects, 2006-2008
Function largely in the summer when student labor is available and recreational activities on the Severn focus citizen concern.
Limited to the tidal Severn, a major recreational resource
Emphasize dissolved oxygen (DO) monitoring because: Low dissolved oxygen often limits available habitat for Chesapeake organisms Dissolved oxygen levels are minimal in the summer DO can be readily measured using portable oxygen electrodes Media have played up the Chesapeake’s “dead zone”
Water clarity measurements used to assess submerged aquatic vegetation habitat
Salinity measurements used to assess water movement in the tidal Severn
Collaborated with DNR Fisheries and Arlington Echo to monitor larval yellow perch in March-April in the upper Severn
Multicellular organisms require oxygen
0.2 mg/l Anoxia--death of benthic organisms
5 mg/l Minimun DO for “open water” (most of Chesapeake and all of the Severn)
