High Density Digital Tape (HDDT) Landsat Data Recovery
High Density Digital Tapes (HDDT) containing Landsat scenes arrive at EROS from International Cooperators located around the world. Operators use a baking process to recover the imagery from the HDDTs.

Lava Sampling From Active Lava Flow
This video clip shows HVO geologist Tim Orr sampling lava from an active pāhoehoe breakout on the episode 61g lava flow. The chemistry of these lava samples provides information on the magma plumbing system. Sampling has been a regular part of monitoring Kīlauea Volcano's ongoing Pu‘u ‘Ō‘ō eruption.

New USGS Maps of Mars Reveal Ancient Oases
Flyover of the southeast Ceti Mensa map. Distinct groups of rock layers, called geologic units, are shaded in different colors, with dark browns representing the oldest rocks and green representing the youngest rocks. All of these rocks formed as wind-blown sand that became trapped in shallow, ephemeral lakes, similar to the wet playas of the desert southwest US.

Reach-Scale Monitoring | Advances in Stream Gaging
The Arizona Water Science Center demonstrates new methods in Reach-Scale Monitoring to improve accuracy and measurability of high flow events. By installing pressure transducers and using LiDAR to measure topography data, hydrologists are able to simulate flows with two dimensional models which will help better calibrate stream gages.

H1 East Transect – May 2017
Permanent Site: H1 East Transect; Depth: 5.9 Meters (19.5 Feet); Distance from river mouth: 2.4 Kilometers (1.5 Miles) east; Pre/Post Dam Removal: 6 years post-dam removal; Lat/Long: 48.1479177,-123.53472865; Site Description: This is a shallow site and one of the farthest removed from the effects of the sediment plume outside of the control sites.

Time-lapse sequence shows Halema‘uma‘u gas plume
This time-lapse sequence shows the outgassing plume from the Halema‘uma‘u lava lake at the summit of Kīlauea. The images were captured by a camera on the flank of Mauna Loa on May 19, 2017. As the plume rose from the vent, it reached the atmospheric inversion layer, which effectively capped the height of the plume.

Potential Corrosivity of Untreated Groundwater in the United States
- Corrosive groundwater, if untreated, can dissolve lead and other metals from pipes.
- National maps have been prepared to identify the occurrence of potentially corrosive groundwater in the U.S.
- These findings have the greatest implication for the 44 million people dependent on domestic wells for drinking water.

Using Drought Forecasts to Improve Natural Resource Management
Natural resource managers face increasing challenges in dealing with drought. As competition for water increases between its various uses (water supply, energy demands, ecological services, recreation, and other environmental and ecological needs), our ability to forecast the onset and termination of drought becomes ever more important.

Anadromous Steelhead and resident Rainbow Trout interactions
This video captures both the resident and anadromous forms of (Oncorhyncus mykiss) Rainbow Trout in a small tributary in the upper Cowlitz River Basin, Washington during spawning season. The male Rainbow Trout exhibits a courting behavior as it quivers against the side of the larger female (HOR) hatchery origin steelhead.
