Salinity & Temperature

Forecasts for the Chesapeake Bay

Summary
Quick Summary

The Chesapeake Bay Environmental Forecast System used to evaluate hypoxia also forecasts salinity and temperature throughout the Chesapeake Bay. Salinity and temperature are predicted for the same dates as the dissolved oxygen:

  1. Nowcast: present-day conditions in the Chesapeake Bay
  2. 2-Day Forecast: conditions in the Bay 2 days from now, and
  3. Forecast Trend: difference between nowcast and forecast
Zoomable maps of salinity and temperature are available through the MARACOOS OceansMap Chesapeake Bay webpage. Choose "ChesROMS Salinity Forecast" or "ChesROMS Temperature Forecast". We have had the best experience using the Google Chrome web browser on a personal computer.

Salinity can be viewed through time at select locations to understand the seasonal and weekly changes in  salinity in the Chesapeake Bay. Overlaying the modeled salinity on top of long-term averages from observed data shows how the forecasted salinity compares to the historical average. Grey lines show one standard deviation above and below the average.

Water temperature can be viewed through time at select locations to understand the seasonal and short-term changes in temperature in the Chesapeake Bay. Overlaying the modeled temperature on top of long-term averages from observed data shows how the forecasted temperature compares to the historical average. Grey lines show one standard deviation above and below the average.
