Drought and wildfire pose enormous threats to the integrity of natural resources that land managers are charged with protecting. Recent observations and modeling forecasts indicate that these stressors will likely produce catastrophic ecosystem transformations, or abrupt changes in the condition of plants, wildlife, and their habitats, in regions across the country in coming decades. In this project, researchers will bring together land managers who have experienced various degrees of ecosystem transformation (from not yet experiencing any changes to seeing large changes across the lands they manage) to share their perspectives on how to mitigate large-scale changes in land condition. The team will conduct surveys...

Album caption and index card: Two ledges of basalt spectacularly exposed in the east wall of the Grand Canyon of the Yellowstone at The Narrows near Tower Falls. The light-colored rocks between the basalt flows are ancient stream gravels deposited about 1.5 million years ago, when the channel of the Yellowstone River was farther east and not as deep as it is today. The hill is capped by lake sediments, sand, and gravel deposited when the Yellowstone River was blocked by a glacial dam farther downstream (to the left). The brown rocks at the base of the cliff are Absaroka andesite breccias. Yellowstone National Park, Wyoming. 1970. Published as a portion of Figure 33 (upper photo) in U.S. Geological Survey Bulletin...

PI-CASC regularly interacts with a diverse and extensive network of stakeholder organizations at federal, territory, state, county, and local levels across the Pacific Region, supporting communication and iterative problem solving between researchers, managers, and decision makers. In addition to these partnerships, PI-CASC has two important ongoing collaborative initiatives. Pacific Islands-Alaska CASC collaboration The PI-AK CASC collaboration is aimed at bringing together scientist and resource managers from the Pacific and Alaska regions to share insights on related climate adaptation challenges in Ridge-to-Reef (R2R) and Icefield-to-Ocean (I2O) ecosystems. Similarities in landscapes and communities in these...

Note the man standing at the base of the deposited debris and a second man standing on the lower edge of the cavity at the top of the slide. Additional incipient flow failures with much smaller movements also occurred on the convex hill to the left of the principal landslide.

This dynamic data release presents an aquatic reflectance product with 20-meter spatial resolution derived from Sentinel-2 satellite imagery for the conterminous United States using the Atmospheric Correction for OLI “lite” (ACOLITE). Aquatic reflectance, noted Rhow in ACOLITE documentation, is defined here as unitless water-leaving radiance reflectance and represents the ratio of water-leaving radiance (units of watts per square meter per steradian per nanometer) to downwelling irradiance (units of watts per square meter per nanometer) multiplied by π. This is also known as remote sensing reflectance (units of per steradian) multiplied by π. These data are intended for use in remote sensing of water color and differ...

The Coupled Ocean-Atmosphere-Wave-Sediment Transport (COAWST v3.8; Warner and others, 2019; Warner and others, 2010) modeling system was used to simulate ocean circulation, water levels, and waves that occurred during Hurricane Dorian (2019) along the US East coast. Simulations were then further downscaled to focus on the resulting inundation, dune overtopping, and barrier island breaching during the storm along North Core Banks, NC. Simulations were performed with coupled and concurrent ocean and wave models simulated on a series of refined, cascading grids. The largest scale grids covered the entire US east coast (5km resolution), and subsequent grids downscaled to the Carolinas region (700m resolution), then...
