HVO monitoring equipment on the north rim of Pu‘u ‘Ō‘!
HVO monitoring equipment on the north rim of Pu‘u ‘Ō‘!The communications hub at Pu‘u ‘Ō‘ō is precariously perched on the north rim, which is actively collapsing. This hub, and the PN cam behind the hub (to the left of image) will ultimately fall into the crater as the north rim continues to collapse.

USGS Nevada Groundwater Site 393310114475001
Did you know the USGS has been studying groundwater since we were founded? USGS first measured the groundwater level at the well in this photo in 1918, over one hundred years ago! How often water levels are measured at a site in the USGS groundwater monitoring networks varies, depending on the scientific purpose of the measurement.

Arid grassland
Arid grasslands in the U.S. Mexico border are fire adapted and used by diverse groups. Science from the Southwest Biological Science Center and the Restoration Assessment and Monitoring Program for the Southwest (RAMPS) is helping these groups find common ground to manage this dynamic landscape.

Managing Fire on the US Mexico Borderlands
RAMPS met with DOI Office of Wildland Fire, US Customs and Border Patrol, and US Fish & Wildlife Service staff at Buenos Aires National Wildlife Refuge in southern AZ last November. The group is developing tools to reduce wildfire risk, conserve wildlife habitat and natural resources, and increase safety and security of border operations.

Keller Well measurements and water sampling on December 10
Keller Well measurements and water sampling on December 10On Tuesday, December 10 HVO staff visited Keller Well, a deep borehole at the summit of Kīlauea, to take quarterly measurements and samples. This photo shows an extra long measuring tape, which has a sensor attached to the end, being lowered into the well to measure the distance to the top of the water table.
