This Coastal Change Storm Hazard Team forecast was made at 4 AM CDT August 26, 2020 and shows forecast beach erosion at the base of the dunes (the strip of colored bars closest to the coast), overwash (middle strip) and inundation (outer strip) from Hurricane Laura.  The model accounts for sandy beaches and barrier islands and does not include marshes,

This USGS streamgage on Schantz Spring near Wescosville, Pennsylvania was partially submerged after floodwaters from Tropical Storm Isaias quickly rose and flooded the area.

Fisseha Mengistu, USGS hydrologic technician, uses a device that lowers a water sampler into the creek below to collect samples used for water quality testing. Experts will be able to use this data to track how Tropical Storm Isaias impacted water quality in the area. This work was done on Rock Creek in Washington, D.C.

USGS coastal change experts predict that storm waves kicked up by the Category 1 hurricane are likely to cause some erosion at the base of the dunes along about 11 percent of coastal beaches between Florida and Virginia.

This rapid deployment gauge was installed August 1 in Swansboro, North Carolina on the White Oak River to monitor water levels in order track potential flooding caused by Tropical Storm Isaias. Photo by Bryce McClenney, USGS. 

This oblique view looking toward the northwest shows the location where a river valley cuts through the rim of Jezero crater and ends in a fan-shaped delta deposit. The Perseverance Mars rover will land near this delta to search for evidence of past life and collect samples that could be returned to Earth by a later mission.

Description: This is a high-resolution oblique view of the southern edge of the delta deposit in Jezero crater, the landing site for the Perseverance Mars rover. In the foreground, a butte of delta material stands above the crater floor.

Description: This is a high-resolution oblique view of the northeastern edge of the delta deposit in Jezero crater, the landing site for the Perseverance Mars rover. In the foreground, buttes of delta material stand above the crater floor. On the left and in the middle of this image, the layered rocks of the delta deposit are visible.

When you’re planning to explore someplace new, it’s always a good idea to bring a map so you can avoid dangerous terrain. This is true whether you’re heading out for a hike on Earth or you’re landing a rover on Mars!

Description: This oblique view looks to the west from above the Jezero crater floor, over the fan-shaped delta deposit, and into the valley that cuts through the crater rim. The Perseverance Mars rover will land near this delta to search for evidence of past life and collect samples that could be returned to Earth by a later mission.

Description: This oblique view looking toward the northwest shows the western rim and floor of Jezero crater, Mars. A river valley cuts through the rim and ends in a fan-shaped delta deposit. The Perseverance Mars rover will land near this delta to search for evidence of past life and collect samples that could be returned to Earth by a later mission.

Mineral elements provide the color in fireworks. Barium produces bright greens; strontium yields deep reds; copper produces blues; and sodium yields yellow. Other colors can be made by mixing elements: strontium and sodium produce brilliant orange; titanium, zirconium, and magnesium alloys make silvery white; copper and strontium make lavender.
