As waters in the northern part of the Chesapeake Bay drop to near freezing temperatures, the CBIBS field team--working with their partners at the U.S. Coast Guard and University of Maryland Center for Environmental Science--makes sure buoys stay save over the winter. For the four northernost buoys, this means they are pulled from the water to protect their sensors and hulls.
The CBIBS field and technical team, in collaboration with partners from NOAA Sanctuaries and the Virginia Institute of Marine Science, has deployed a CBIBS buoy at York Spit, at the mouth of the York River.
Many Chesapeake-area residents have noticed very clear water in the Bay in recent weeks, and scientists are working together to further explore this topic. While images from some Bay tributaries show terrific visibility in the water—being able to see the bottom in 10 feet of water, for example—scientists want to validate the phenomenon using data from a variety of sources.
There’s a chill in the air, and with an eye toward keeping CBIBS buoys safe from ice damage, several of the northernmost CBIBS buoys will be pulled for the 2015-16 winter and redeployed in early spring.
The frozen waters the Chesapeake Bay saw in early 2015 have long since melted, but CBIBS buoy technicians continue their work to minimize problems CBIBS buoys may encounter due to icing in future winters.
