As the weather heats up, many Bay residents and visitors consider taking a swim in the Chesapeake. Knowing where they might see the sea nettle Chrysaora quinquecirrha—commonly referred to as “jellyfish”—can help swimmers avoid a stinging encounter.

Now available at the Susquehanna CBIBS buoy: nitrate levels. The first nitrate sensor in the CBIBS system was deployed on the Susquehanna buoy because the Susquehanna River provides roughly 40% of the freshwater flow into the Chesapeake Bay. Nitrates, a form of nitrogen, exist naturally and are an important nutrient used by plants to fuel their growth.

Many people who enjoy spending time on and in the Bay are planning summer getaways and adventures. And it’s getting hot!

This year the nation commemorates the bicentennial of the start of the War of 1812, which saw conflict between the young United States and Great Britain that lasted through 1815. The Chesapeake Bay was a significant theater during the war, featuring efforts including Joshua Barney's Chesapeake Bay Flotilla and significant events like the Burning of Washington.

The Susquehanna CBIBS buoy, located at the mouth of the Susquehanna River near Havre de Grace, Maryland, was redeployed today, thanks to NOAA's partners at the U.S.

On February 28, the NOAA Chesapeake Bay Office, which manages the Chesapeake Bay Interpretive Buoy System (CBIBS), welcomed regional scientists and observation network experts to talk about how they currently use data from CBIBS—and how they might in the future.

Early last year (January 2011), roughly 2 million dead fish—primarily young spot—washed ashore in the mid Chesapeake Bay.

Soon after the CBIBS field team got the First Landing buoy back up and running from repairs to damage from Hurricane Irene, the buoy sustained additional damage to its top structure, including the anemometer and temperature/humidity sensor. This means that the following parameters are not currently available:

Thanks to U.S. Coast Guard Baltimore, the Susquehanna CBIBS buoy was pulled from the water today for over the winter. The buoy's location as the northernmost CBIBS buoy and at the mouth of the Susquehanna River means it is in relatively fresh water that is quite susceptible to freezing.

The First Landing buoy can experience strong currentsThe First Landing buoy—the tenth buoy in the Chesapeake Bay Interpretive Buoy System—was deployed in mid-August, but it was soon damaged in the high wind and seas of Hurrica
