Eyes on Earth Episode 4 - Cataloging Earth Observation Satellites
Eyes on Earth Episode 4 - Cataloging Earth Observation SatellitesEarth observation used to be the province of a handful of countries with satellite technology. Today, hundreds of satellites built all over the world are launched every year. This episode of Eyes on Earth talks about the explosive growth in the civilian and commercial remote sensing and EROS’ role in it.

Graham Lederer examines tungsten ore from Burnside mineNortheast Region Photo Contest Winner | Oct. 2019 | Honorable Mention 1
Graham Lederer uses a hand lens to examine tungsten ore from the Burnside mine in Alpine County, California. Scheelite is an important tungsten mineral found in skarn deposits throughout the Sierra Nevada and Great Basin.

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.

This timelapse video covers about 30 minutes of activity at the water pond in Halema‘uma‘u at the summit of Kīlauea. Water appears to be flowing into the pond from several locations, including the southern boundary (right side in this image). A small amount of material is also seen floating on the surface at the eastern end of the pond (top of image).

Boise State University Master’s student Kristina Parker uses a syringe to collect blood from a Great Basin rattlesnake (Crotalus oreganus lutosus). The blood’s ribonucleic acid, or RNA will be analyzed to track genetic change in the snake from habitat disturbances. RNA, along with deoxyribonucleic acid – or DNA, are the molecules that carry genetic information.

Video of circulation in the Halema‘uma‘u water pond
Video of circulation in the Halema‘uma‘u water pondThis time-lapse video shows circulation in the water pond in Halema‘uma‘u over a period of about 25 minutes. There appears to be an influx of water along the southern (right) shoreline. A broader eastward flow of water (toward top of image) is evident. The video is shown twice. USGS video.
