NOAA ship Reuben Lasker docked in San Francisco with the Bay Bridge in the distance. On October 21, leadership from NOAA, USGS, and BOEM met with the scientists and crew of the EXPRESS expedition to learn about the multi-agency cooperative research campaign.

Wildfires burned across Lebanon in mid-October 2019. A pair of images taken just 10 days apart by the European Space Agency's Sentinel-2A satellite show the burn scar from one of the larger wildfires.

In Kīlauea's lower East Rift Zone, a closed chamber was used to measure the rate of CO2 emitted directly from the ground near a crack emitting steam. USGS scientists continue to track changes in Kīlauea's lower East Rift Zone after last year's eruption. USGS image by P. Nadeau.

A view of the mouth of the Klamath River where it meets the Pacific Ocean in northern California. The river runs from Oregon to California. Four dams along the Klamath are pending removal. USGS is studying coastal watershed response to dam removal, including long-term before-after/control-impact (BACI) studies.

USGS scientists measured gases in an area uprift of the 2018 fissure system on November 8. In this area, vegetation has died because of lingering heat and steam. In some areas of Kīlauea's lower East Rift Zone, residents report smelling gases that are likely generated by decaying organic matter rather than magma degassing. USGS image by P. Nadeau.

On November 8, 2019, USGS volcano scientists visited Kīlauea's Lower East Rift Zone to measure ambient gases, as well as the soil carbon dioxide (CO2) flux and temperature. This photo, looking in a southeast direction, shows some steaming uprift of the 2018 fissure system.

Black Racer snake (A) The epidermis over much of the body, but cranially pronounced, has multifocal to coalescing dull white to pale gray foci. (B) Multiple scales around the head are thickened and roughened. (C) Ventrally, there are multiple dull white to grey foci of up to 8 mm size, occasionally with central indentations.
