The active lava lake within Halema‘uma‘u crater about 3 weeks before magma began to withdraw from beneath the crater. Visible in the middle left of the photo behind the plume, is the old Overlook parking area, closed since 2008. The parking area slumped into the crater by June 21. View is toward the southwest.

Chain of Command
USGS personnel control chain as it went through a block on recovery of a seafloor platform. The platform had been deployed off Matanzas Inlet, FL in winter 2018 to assess storm effects on coastal inlet dynamics.

Quadpod Recovery
USGS team and R/V Savannah crew prepare to lower the quadpod deployed at the nearshore site onto the deck during recovery operations. Note all the hairy encrusting organisms that grew in 3 months and how close to the shoreline the ship is.

USGS Scientists at Capitol Hill Roundtable on Extreme Events
On April 12, the USGS, together with the American Fisheries Society (AFS), hosted a roundtable discussion with congressional staff centered on the impacts of extreme weather events like hurricanes, floods, droughts, and wildfires on inland fish. Scientists with the USGS National Climate Adaptation Science Center (NCASC) are investigating how climate-relate

Dead Run is a typical urban creek in the Baltimore area (photo 1)
Dead Run is an urban creek in Catonsville, Maryland, near Baltimore. Research has found that about half of the bed sediment originates as particulate matter on pavement that then is washed into the creek via storm drains.
