5/19/14 – 5/23/14

Students, with help from parents, teachers and SERC staff, recorded the following data. We used a combination of means, medians, and ranges to best represent this comprehensive data for all Estuary Chesapeake programs. The water quality data is a combination of means and medians of observed conditions. For the oyster community and seining stations, observed organisms are noted either by a “✓” check mark, or by the total number of organisms found, depending on what was recorded on the data sheet. If no individuals were identified for a species, it is noted by a 0. “X” indicates instances of insufficient or incomplete data.
