The Chesapeake Bay has been a repository for nitrogen, phosphorous and sediment loads to the point that its water quality is endangered. The Bay Barometer: Health and Restoration in the Chesapeake Bay Watershed is a report from the Chesapeake Bay Program that looks at ecological markers, like underwater grasses and fish, to measure progress in restoration goals.
It is most common at this time of year for scientific weather instruments to be found in the woods and forests.
Phil Hysell of the National Weather Service says what goes up-in this case miniature weather stations known as radiosondes-does come down.
Radiosondes are launched into the atmosphere twice a day across the country and can reach heights of over 100,000 feet. During their ascent, these devices send back valuable measurements of temperature, humidity, pressure and wind direction and speed that go into weather forecast models.
