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 Thera cluster is named for the volcanic island Thera (also known as Santorini), the southernmost member of the Cyclades island group in the Aegean Sea. The cluster is dominated by an earthquake sequence that began in early February, 2025, 20-40 km northeast of Thera. The sequence has swarmlike characteristics but it is, as yet, unclear if the activity is volcanic or tectonic in nature. The cluster includes the 7.7 Mw tsunamigenic earthquake of July 9, 1956 and 3 of its aftershocks. The mainshock is located ~10 km southeast of the southern end of the ongoing 2025 swarm, midway between the southern end of the Santorini-Amorgos Fault and the Anafi-Astypalaea Fault (Leclerc, F., Palagonia, S., Feuillet, N. et al....

On September 20, 2017, Hurricane Maria hit the U.S. territory of Puerto Rico as a category 4 storm. Heavy rainfall caused landslides in mountainous regions throughout the territory. This data release presents geospatial data describing the concentration of landslides generated by Hurricane Maria in Puerto Rico. We used post-hurricane satellite and aerial imagery collected between September 26, 2017 and October 8, 2017 to visually estimate the concentration of landslides over nearly the whole territory. This was done by dividing the territory into a grid with 4 square km cells (2 km x 2 km). Each 4 square km grid cell was classified as either containing no landslides, fewer than 25 landslides/ square km or more than...

This data release contains tracer data and estimated age distributions of groundwater samples collected as part of a water availability study for the Mississippi alluvial plain (MAP). The MAP is the floodplain of the lower Mississippi River and its main tributaries and distributaries. The soils, climate, and irrigation water resources of the MAP have made it a highly productive agricultural region for the nation. The surficial aquifer of the MAP, the Mississippi River Valley alluvial aquifer (MRVA) supplies most of the irrigation water for the region. Parts of the MRVA overlie and may exchange water with the Mississippi embayment aquifer system (MEAS) (Kresse and others, 2014). The MRVA has shown signs of severe...
