2" galvanzied pipe mated to a custom PVC clamp mount are used to fasten a horizontal ADVM.

About 1300 earthquakes with magnitudes greater than 1 and at depths over 20 km (12 mi) on and around the Island of Hawai‘i since August 2019 are depicted on this map. Most of the earthquakes were clustered beneath the southern edge of the island near the town of Pāhala.

Kentucky mount constructed from Speed Rail. This mount can be used to deploy Rio Grande, RiverPro, RioPro, and RiverSurveyor ADCPs.

A mangrove forest along the western Gulf of Mexico coast (near Tuxpan, Veracruz, Mexico). With warming winters, mangrove forests are expected to expand northward at the expense of salt marshes in parts of Texas, Louisiana, and north Florida.

Map of seismicity (yellow circles) in the Yellowstone region during 2019. Gray lines are roads, red line shows the caldera boundary, Yellowstone National Park is outlined by black dashed line, and gray dashed lines denote state boundaries.

Color-coded map showing the range of helium isotope values across Yellowstone National Park. BC = Boundary Creek, GGB = Gibbon Geyser Basin, MHS = Mammoth Hot Springs.

Map panels showing the distribution of major caldera-forming ash-flow deposits from the three major caldera-forming eruptions on the Yellowstone Plateau Volcanic Field. Updated from Christiansen, 2001 (USGS PP 729-G) with new age information.

Map showing ice cover in the Yellowstone region. Light shaded areas bounded by black and red lines indicate areas covered during the Pinedale (about 20,000-15,000 years ago) and Bull Lake (about 150,000 years ago) glaciations, respectively. Blue lines are contours in thousands of feet on the maximum reconstructed Pinedale glacier surface.

High ice content permafrost bluff erosion at Barter Island in 2019 after several coastal storms and a prolonged time of anomalously high air temperatures. 

Maps displaying the stages of evolution of the more recent cycle of volcanism associated with Yellowstone Caldera. From Finn and Morgan, 2002 (High-resolution aeromagnetic mapping of volcanic terrain, Yellowstone National Park).

Synchrotron X-Ray microtomography 3D image (a) and cathodoluminescence slice (b) from the same reentrant-bearing quartz crystal from the Lava Creek Tuff. The reentrants are in darker blue in (a) and the black cavities in (b). Note their relationship to quartz growth bands. Red domains are small magnetite crystals.

A coral reef in the Turks and Caicos Islands dominated by the weedy coral species, Porites astreoides. The relative dominance of this taxa has increased throughout the western Atlantic.
