The Baltimore Harbor and Annapolis buoys were pulled in mid-January to keep them safe from ice damage. They will be redeployed when temperatures warm to an appropriate level. Gooses Reef and Potomac buoys are not communicating, perhaps due to icing on the solar panels or antenna or other weather-related issues. When the weather allows, we hope to get out to diagnose any other issues if they persist.

The NOAA Chesapeake Bay Office’s Fall 2025 Seasonal Summary describes how Bay conditions in September–November differed from average—and how those differences may have affected important species in the Chesapeake. Here are some of the elements discussed in the Fall 2025 Seasonal Summary.
At the end of each meteorological season, scientists analyze data from the previous three months. They define whether conditions were average—or whether they differed from average.
The NOAA CBIBS Patapsco buoy has been redeployed and renamed the NOAA CBIBS Baltimore Harbor buoy to better reflect its location. It had been pulled to keep it, and its sensors, safe from potential damage due to icing over the winter.
Data from CBIBS buoys, satellites, and other sources can highlight where water conditions differ from average.
The NOAA Chesapeake Bay Office’s (NCBO) seasonal summaries use data collected from CBIBS buoys, satellites, and other data sources to assess water conditions.
After every season, NOAA Chesapeake Bay Office scientists examine observations from CBIBS buoys, satellites, and other data sources to determine how Bay conditions compared with the average over the past 20
