What is the salinity of the Chesapeake Bay?
25 to 30 ppt
Chesapeake Bay salinity Salinity is highest at the mouth of the Bay—averaging 25 to 30 ppt—where water from the Atlantic Ocean enters. The head of the Bay and its tidal rivers are fresh, with a salinity of less than 0.5 ppt.
Is the Chesapeake Bay saltwater or brackish water?
The Chesapeake Bay is an estuary, it has fresh water, salt water and brackish water. Brackish water has three salinity zones: The Susquehanna River to north Baltimore is freshwater. From north Baltimore to the Chesapeake Bay Bridge is known as the oligohaline zone and has very little salt.
Why does the salinity of the Chesapeake Bay change from north to south?
The Chesapeake Bay’s salinity is highest at its mouth, where sea water from the Atlantic Ocean enters. The Coriolis Force, a phenomenon caused by the earth’s rotation, pushes flowing water in the Northern Hemisphere to the right, so saltier water moving up the Bay veers toward the Eastern Shore.

Why is the Chesapeake Bay so dirty?
The Chesapeake Bay has been on EPA’s “dirty waters” list for decades. This excess nitrogen and phosphorus feeds algal blooms that block sunlight to underwater grasses and contribute to the formation of dead zones, areas in the Bay and its tidal waters without sufficient levels of oxygen.
Is 75 degree water too cold for swimming?

Unfortunately, the Chesapeake Bay faces serious problems due to human activities, including polluted stormwater runoff, over-fertilization and pollution from animal wastes, deforestation, wetland destruction from agricultural, urban, and suburban development, and sea level rise caused by global climate change.
Where can I see salinity levels in the Chesapeake Bay?
To see salinity levels throughout the Chesapeake Bay, visit Eyes on the Bay (for Maryland waters) or Virginia Estuarine and Coastal Observing System (for Virginia waters). Salinity varies widely from season to season and from year to year, depending on the amount of fresh water flowing from the Bay’ rivers.
What are the water temp in the Chesapeake Bay?
Because the Chesapeake Bay is so shallow, it cannot store heat over time. Water temperatures in the Bay fluctuate widely throughout the year, ranging from 34 degrees in winter to 84 degrees in summer.
Why is the water in the Chesapeake Bay saltier?
The water on the Bay’s eastern shore tends to be saltier than water on the western side, due to two factors: Most fresh water enters the Bay from its northern and western tributaries, including the Susquehanna and Potomac rivers.
How often does cbofs do the Chesapeake Bay forecast?
CBOFS generates water level, current, temperature and salinity nowcast and forecast guidance four times per day. Aerial animations of the whole Chesapeake Bay as well as time series at particular stations or points of interest are available for over 58 locations for the five parameters (water level, currents, temperature, and/or salinity).
