4/4/11 – 4/22/11

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 “−”. “X” indicates instances of insufficient or incomplete data.

If you are curious about more types of water quality tests, would like to see how your data compares to scientists’ data, or would like to see more complete data about the Rhode River, you can check out this link to a site called Eyes on the Bay. This link will take you right to the Rhode River data provided by the Smithsonian Marine Science Network that Eyes on the Bay connects with.
