This data set contains imagery from the National Agriculture Imagery Program (NAIP). The NAIP program is administered by USDA FSA and has been established to support two main FSA strategic goals centered on agricultural production. These are, increase stewardship of America's natural resources while enhancing the environment, and to ensure commodities are procured and distributed effectively and efficiently to increase food security. The NAIP program supports these goals by acquiring and providing ortho imagery that has been collected during the agricultural growing season in the U.S. The NAIP ortho imagery is tailored to meet FSA requirements and is a fundamental tool used to support FSA farm and conservation programs....

Fig. 20. Dive light [(about 8-in (15-cm) long] is resting vertically on accumulation of sunken calcite rafts about 4 ft (1.2 m) below water surface, west wall of Browns Room. The accumulation resembles a miniature talus. Water surface and folia are visible near the top and right corner of photo, respectively. 1986.

In support of paleoclimatology investigations, samples of mammillary calcite, calcitic folia, and flowstone were collected by the U.S. Geological Survey in Devils Hole and Devils Hole Cave 2, Nevada, between 1983 and 1996. These samples came from about 60 m below to 9 m above the modern water table in these caverns. To determine δ18O and δ13C time series spanning the interval 567.7–4.5 ka, more than a thousand samples were milled and analyzed for their δ18O and δ13C values. To determine time-series ages, more than a hundred samples were analyzed using uranium-series dating. Many of these measurement results have not been published. Herein, we provide previously unpublished δ13C and δ18O values, and we provide unpublished...

Fig. 19. Folia and popcorn, two different types of speleothems, below water surface (seen at top of photo) at NE corner of pool in Browns Room. From the water surface to bottom of photo is about 4 ft (1.2 m). The occurrence of both popcorn and folia underwater suggest that the water table was lower in the past. 1986.

The mid-to-late Pleistocene Devils Hole δ18O record has been extended from 60,000 to 4500 yr ago. The new δ18O time series, in conjunction with the one previously published, is shown to be a proxy of Pacific Ocean sea surface temperature (SST) off the coast of California. During marine oxygen isotope stages (MIS) 2 and 6, the Devil Hole and SST time series exhibit a steady warming that began 5000 to > 10,000 yr prior to the last and penultimate deglaciations. Several possible proximate causes for this early warming are evaluated. The magnitude of the peak δ18O or SST during the last interglacial (LIG) is significantly greater (1 per mill and 2 to 3°C, respectively) than the peak value of these parameters for the...

Fig. 6. View looking up from Anvil Rock (immediately above D in Fig. 4) in main chamber of Devils Hole at about 80 ft (24.4 m) below water surface. The planar fissure strikes NE and dips 70–80 degrees to SE. Widths of the fissure typically range < 6.5 ft ( <2 m). White translucent mammillary calcite coats hanging wall (left in photo) of Paleozoic carbonate bedrock. Footwall (right in photo) is barely visible in the narrow fissure.

This U.S. Geological Survey (USGS) data release consists of a spreadsheet presenting high-frequency water levels in feet below a measuring point (MP) at Devils Hole in Nye County, Nevada. Water-level data are collected at USGS site 362532116172701 by the National Park Service, using a data logger programmed to collect water-level every 15 minutes or every 5 seconds when a water-level change greater than 0.015 feet is detected. Data are analyzed, approved, and audited according to USGS standards as described in U.S. Geological Survey Office of Surface Water memo 2017.10. Continuous 15-minute data are published in the National Water Information System (NWIS) database. Irregular periods of 5-second data collected during...

Fig. 24. West wall in Browns Room about 5 ft (1.5 m) below water surface. The reason for the discoloration beginning at about 3 ft (1 m) below water surface is unknown.
