Automated lagrangian water-quality assessment system (ALWAS) measurements of North Slope lakes and the Bering Glacier, Alaska
ALWAS is a relatively inexpensive, free-floating, sail-powered or jet-driven water quality measuring and watershed evaluation buoy. It is capable of measuring a data point with multiple parameters as rapidly as every 40 seconds. Data is transmitted for real-time viewing and is stored for future retr...
