BisonCore’s Collision Detection Avoidance Algorithms safely keep the vehicle from running into obstacles
linkUAS Research Center's BisonCore Project, augments an autonomous rover to avoid running into obstacles. Shown in picture; user set waypoint (2) that runs over a curb/barrier. CDA engaged and navigated south avoiding, and seeking a path around, the curb.

Winter temperature extremes control the distributions of subtropical fishes. Common snook (Centropomus undecimalis), aggregate at a spring in northern Florida during winter. Snook are warm saltwater game fish, common in Florida, that have been moving further northward as extreme cold spells become less frequent and less intense.

The USGS landslide team monitors and continues to update the hazard map models based on data collected in burn areas. This information improves future models and provides better hazard assessments used by officials for emergency response and decision making. Many of the steep hillsides burned and denuded in California fires repel water rather than soak it in.

This is a view of a USGS surface water stream gage that contains equipment to monitor discharge at the Williamson River below the Sprague Ruver in Chiloquin, Oregon. The gage house contains a historic stilling well and a device that records the level of water. It also has a water temerature sensor and a turbidimeter.
