Thirty Bureau of Meteorology, Climatology and Geophysics (BMKG) senior staff members received USGS/IRIS training in Advanced Seismology and Tsunami Warnings (Oct. 14-18, 2019). Most of the staff members are in this photo.

USGS scientists on the back deck of M/V Bold Horizon in San Francisco Bay: (back row, standing: left to right) Brandon Nasr, Danny Brothers, Travis Alonghi (USGS student contractor), Gerry Hatcher, Jenna Hill, Pete Dal Ferro, and Jenny McKee; (front row, kneeling: left to right) USGS scientists Janet Watt and Nora Nieminski.

USGS scientists collect gas from the Puhimau thermal area on Chain of Craters Road in Hawai‘i Volcanoes National Park. The gas is collected in evacuated (vacuum-pumped so that no gas at all is inside) glass bottles, and a system of a syringe with tubing helped ensure minimal contamination by ambient atmospheric gases.

Puhimau thermal area has the largest naturally occurring population of the endangered plant, Portulaca sclerocarpa (marked by the blue flag in the photo), and is the site of National Park Service restoration efforts for this species.

The USGS Coastal and Estuarine Dynamics Group will be deploying a cross shore array at Pea Island, various intruments will be connected to the poles to measure oceanographic conditions

Goleta Beach in Santa Barbara experienced an unusual storm and large wave event in the Spring of 2014. Gaviota Pier, seen far off in the background, sustained heavy damage as did the restaurants on the pier and nearby. The USGS conducts seasonal surveys throught the year to see how the beaches are changing through time.

USGS Hawaiian Volcano Observatory and DOI Office of Aviation staff prepare the sampling mechanism (on blue tarp) and inspect the Unmanned Aircraft System (UAS) just before it took off to collect water from the Halema‘uma‘u crater lake. Brightly-colored flagging tape tied to a cable attached to the UAS indicated depth as the sampling tool was lowered into the water.

Water collected from the lake at the bottom of Halema‘uma‘u is prepared for laboratory analyses at the USGS California Volcano Observatory. Results thus far reveal chemistry indicative of complex reactions between the water, magmatic gases, and Kīlauea's basaltic rocks. USGS photo by S. Peek, October 2019.

The "Short-term Sulfur Dioxide Advisory Level Information" table (http://www.hiso2index.info/assets/FinalSO2Exposurelevels.pdf) uses a six-tiered color-coded system to depict sulfur dioxide (SO2) concentrations and provide guidance for different groups of people exposed to SO2.

Scientists collected marine vibracores from a research vessel in Mississippi Sound to study shelf geology as part of a collaboration between Mississippi State University and the USGS St. Petersburg Coastal and Marine Science Center.

Two HVO geologists document road cutting activities on HWY 132 on August 7, 2019. One geologist is taking visual photographs while another geologist is taking thermal photographs to make a tandem pair for comparison. The temperature of the solidified lava was measured to 425 ° C (800 ° F) at the digging site. Photograph by USGS geologist K.

Transportation takes many forms; this horse trek to GPS station HVWY in Hayden Valley complies with wilderness regulations, reduces impact to sensitive areas, and enables teams to upgrade equipment to keep the site operational year-round. Site maintenance was completed under permit YELL-2019-SCI-5546, in close coordination with Park staff, on September 18, 2019.
