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

This timelapse sequence shows the water pond in Halema‘uma‘u Crater, at Kīlauea's summit, between November 1, 2019, and March 26, 2020. Over this time the water level rose approximately 14 meters (46 feet), equivalent to 67 cm (about 2 feet) per week. The timelapse shows one image per day (with a few cloudy images removed), and is looped several times.

Field equipment used by USGS Pacific Coastal and Marine Science Center scientists for bathymetric and topographic surveys in the Sacramento-San Joaquin Delta, California

The USGS St. Petersburg Coastal and Marine Science Center strives to provide timely, robust science using modern methods and state-of-the-art technologies. This involves keeping our facilities and equipment updated.

Hats off to the tireless efforts of WYDOT and county crews for all the plowing to get roads open so we can do our jobs.

Drilling holes to collect samples for water-quality analyses at Green River nr LaBarge was made extra challenging by a temperature of -10F. It takes a lot of planning and quick action to collect and process the sample before equipment and water freeze.

Map and graphs illustrating (A) the extent of the shoreline and dune-base forecast locations (red). The year of (B) the first available and (C) most recent shoreline (red) and dune-base (blue) positions are provided for each transect. (D) Total number of shoreline and dune-base positions used in the analysis are also shown. #, number.

Scanning electron microprobe images show the complexity of tiny Icelandic ash grains (150 micron, or 0.006 inch). Image (a) shows a dense and blocky grain, and (b) shows a foamy grain. Photos by J. Schmith.

The stream at this site is free flowing under the ice, so the relation between stream stage and streamflow works like it does in the summer (or other non-ice months). Real-time flow and stage for Dinwoody Creek abv Lakes online: http://ow.ly/a0L850yr2Nb

Answer: a GPS capable of accurately measuring elevations to within 10 cm (~4 in). In the summer of 2019, USGS organized a Light Detection and Ranging (LiDAR) survey of the Kīlauea summit and East Rift Zone, including both the Pu‘u ‘Ō‘ō and 2018 lower Puna lava flows.

The SQUID-5, or a Structure-from-Motion (SfM) Quantitative Underwater Imaging Device with 5 cameras is a towed surface vehicle with an onboard Global Navigation Satellite System (GNSS) and 5 downward-looking cameras with overlapping views of the seafloor.

Streamflow and water-quality data have been collected at Fivemile Creek near Shoshoni since the 1940s. All data available on line at: http://ow.ly/uraY50ylvIi

It took all of the auger flight plus a little to get through ice to the creek. Collecting sample no. 238 from Muddy Ck nr Shoshoni. Monthly samples create a data set that can be used to describe water quality during different seasons and over time.
