How many jellyfish are in the Chesapeake Bay this year?

One of the two JellyCams, located on the Horn Point Laboratory pier on the Choptank River in Cambridge, Maryland, provides a view of the water surface in order to show local jellyfish conditions. The other JellyCam is at the Chesapeake Biological Lab in Solomons, MD.  Researchers are currently assessing the usefulness of cameras like this one for monitoring sea nettle populations in Chesapeake Bay.  Visual counting has been used to monitor the sea nettle population in Chesapeake Bay for decades, but automating the process by using cameras like this one may allow for more frequent, simultaneous sampling of multiple locations in order to understand new aspects of the sea nettle population. Water quality information for this location can be found here.
