A suite of subglacial water-pressure records from the 1996 summer field season at Trapridge Glacier, Yukon Territory, Canada, discloses a hydraulic event that cannot readily be explained by known forcings. We suggest that these records indicate covert failure of the pressure sensors caused by at least one large water-pressure pulse. The sign and magnitude of the pulse appears to have varied spatially and the pulse duration was less than the 2 min sampling interval of our data loggers. Laboratory experiments support this interpretation and indicate that the pulse magnitude exceeded 900 m of hydraulic head, roughly 15 times the ice-overburden pressure. Within glaciers, large water-pressure pulses can be generated...

The Global Surface Water Occurrence Change Intensity map provides information on where surface water occurrence increased, decreased or remained the same between 1984-1999 and 2000-2015. Both the direction of change and its intensity are documented

This report contains water-quality and sediment-quality data from samples collected in the Yukon River Basin from March through September during the 2004 water year (WY). Samples were collected throughout the year at five stations in the basin (three on the main stem Yukon River, one each on the Tanana and Porcupine Rivers). A broad range of physical, chemical, and biological analyses are presented.
Our mission is to collect timely and reliable information on the water resources of our six-state region (Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, Vermont), and to partner with Federal, State, Tribal, and local agencies in hydrologic studies that advance human health, public safety, and environmental sustainability.

Background and Problem Tully Valley is part of the Onondaga Trough, which extends from the Valley Heads Moraine in the south to Onondaga Lake in the north near Syracuse, New York (fig. 1). The Onondaga Trough is filled with a complex sequence of glacial and post-glacial sediments that overlie Devonian carbonate rock and shale and Silurian shale and salt (fig.2). Mudboils, volcano-like cones of fine sand and silt, have been documented in the Tully Valley since the late 1890s, and have been continuously discharging turbid water into Onondaga Creek since the 1950s (Kappel and others, 1996). Continuous mudboil activity appears to be correlated with salt solution-mining activities in brine fields at the southern...

Taxing Entities consist of a group of people who organize to tax themselves for specific purposes. These may include, but are not limited to: improvement and service districts for repairing or replacing a local road; water and sewer to provide infrastructure to a rural area for water and sewer facilities; conservation districts to help protect natural resources; and fire to provide fire protection services to rural areas, etc.

These data show the results of for Nitrate monitoring in Florida Springs for 2018. Water Quality in Florida Springs is an ecological indicator for the Landscape Conservation Project for Florida. The project entails large-scale assessment of and planning for the health of important natural resources in Florida, known as Conservation Assets (CAs). Conservation planning at the landscape scale provides a framework for safeguarding functional ecosystems, and their interconnected processes necessary to achieve true preservation of healthy resources. Spatially explicit data from the project informs prioritization and coordination for conservation decision-making. A suite of ecological indicators was carefully selected...

The suite of measurement methods available to characterize fluxes between groundwater and surface water is rapidly growing. However, there are few studies that examine approaches to design of field investigations that include multiple methods. We propose that performing field measurements in a spatially telescoping sequence improves measurement flexibility and accounts for hydrologic scale while still allowing for parsimonious experimental design. We applied this spatially telescoping approach in a study of ground water-surface water (GW-SW) interaction during base flow conditions along Lucile Creek, located near Wasilla, Alaska. Catchment-scale data, including channel geomorphic indices and hydrogeologic transects,...

Two sensors, a vented conductivity, temperature and depth sensor (CTD) and a turbidity meter, were installed on a piling at the mouth of McAllister Creek at site MC3 (N 47° 06’ 01”/W 122° 43’ 36”) and connected to a telemetered data collection platform that was used to program, power, and log data for each sensor. Timing of the 15-minute sampling interval was synched among both sensors. The site is tidally influenced. The CTD (InSitu Aqua Troll) measured water temperature, water depth, specific conductance, and salinity from December 24, 2016 to February 17, 2017 (55 days). Water depth ranged from 0.52 to 5.49 meters. Temperature ranged from 1.1 to 9.8 degrees C. Specific conductance ranged from 5,500 to 43,100...

The regional Ozark aquifer potentiometric-surface map shows the altitude at which the water level would have risen in tightly cased wells and represents conditions during the period from November 2014 through January 2015. Water levels were measured during this period to ensure that wells had adequate time to recover from previous summer pumping and prior to the start of the 2015 summer pumping season. Groundwater-level data from 178 wells cased completely in and open to the Ozark aquifer are available from the USGS National Water Information System (NWIS; data available at http:// waterdata.usgs.gov/nwis). Streams and springs in the study area represent the intersection of the groundwater table with land surface;...

In this policy perspective, we outline several conditions to support effective science–policy interaction, with a particular emphasis on improving water governance in transboundary basins. Key conditions include (1) recognizing that science is a crucial but bounded input into water resource decision-making processes; (2) establishing conditions for collaboration and shared commitment among actors; (3) understanding that social or group-learning processes linked to science–policy interaction are enhanced through greater collaboration; (4) accepting that the collaborative production of knowledge about hydrological issues and associated socioeconomic change and institutional responses is essential to build legitimate...
