Dial-a-Buoy877-BUOY BAY

Ten years have passed since Hurricane Isabel tracked through the Chesapeake region with high winds and high water levels. Isabel made landfall near Drum Inlet, North Carolina, around 1 p.m. Thursday, September 18, as a category 2 hurricane with 100 mph winds.

CBIBS buoys track dissolved oxygen—“DO”—levels. Having adequate DO is essential for all species that live in the Bay; like humans, the Bay’s living resources—like fish and crabs—need oxygen. Different species can tolerate different levels of oxygen, but scientists generally agree that the Bay’s aquatic species can survive with at least 5 milligrams of oxygen per liter. 

Additional data from the Gooses Reef CBIBS buoy location is once again available, thanks to deployment of a new acoustic modem that relays water-quality information from the bottom of the Bay to the main buoy.

Parameters tracked there—roughly 37.5 feet below the surface—are:

In addition to providing real-time data on current conditions out on the Chesapeake, through this website, you can also make graphs to help you track trends in any of the parameters observed by CBIBS buoys. This can be done using the quick graph feature on any of the individual buoys' pages or the Data Snapshot page, or by creating a custom graph using the Data Graphing Tool.

Saturday, April 20, 5:01 a.m.: It’s a date and time many Chesapeake-area anglers have had written in pen on their calendars for a long time.

Early spring is a time of big changes on the Chesapeake Bay. One of the key indicators of the transition from winter to spring is water temperatures, which can warm rapidly, thanks in part to the sun’s higher angle.

In recent weeks, the Annapolis CBIBS buoy has occasionally reported wind readings that do not appear to be reliable. For the most part, data from the buoy on wind speed and wind gusts are on target, but in high-wind scenarios, errant “spikes” have been observed. For example, a few readings from the winter storm that moved through the Chesapeake area on March 6 do not appear to be accurate.

Charter boat captains and meteorologists are highlighted as CBIBS users in a new video released by CTIA, The Wireless Association.

Congratulations to Doug Wilson, who was recently presented the American Meteorological Society’s 2013 Francis W. Reichelderfer Award for his work from 2006 to 2012 that led to development and growth of the NOAA Chesapeake Bay Interpretive Buoy System.

Temperatures around the Bay are dropping—but that doesn’t mean the CBIBS field team is hibernating. This week, the CBIBS team partnered with the U.S. Coast Guard to pull two buoys for the 2012-13 winter. The Susquehanna and Upper Potomac buoys are located in the northern reaches of the Bay and are in low-salinity waters, making them vulnerable to potential damage from ice.
