Like with aerial LiDAR, the many benefits of ground ground-based LiDAR are continuing to be discovered. Ground Ground-based LiDAR offers high high-resolution surveys of vertical features like bluffs and stream banks. When the surveys are repeated...

The Great Salt Lake (Utah) is divided by a railroad causeway that causes the lake's south arm to be chemically stratified, when saltier, denser water from the north underflows into the south, creating an anoxic, sulfide-rich deep brine layer that...

Salinity is a driving force for change in hypersaline community structure. The Great Salt Lake is populated at high salinities by the salt-tolerant brine shrimp (Artemia Franciscana) and brine fly (Ephydra gracilis), and lake management decisions...

The Great Salt Lake is bordered by an extensive metropolitan area that discharges its secondary-treated wastewaters to the ecosystem. To compare how three bays of the lake respond to different levels of nutrient loading we measured eutrophication...
