Using Advanced Borehole Geophysical Methods to Characterize Fractures, Foliation, and Fractured-Rock Groundwater Flow at a Geothermal Test Site on Roosevelt Island, New York County, New York

Background The U.S. Geological Survey (USGS) has characterized fractures, foliation, and fractured-rock groundwater flow penetrated by test boreholes in crystalline bedrock underlying Manhattan Island, New York County, New York since 1998. New test boreholes will be drilled on Roosevelt Island in New York County for a Cornell University geothermal test project. Cornell University is...

Identifying Thermal Refuges in the Schoharie Watershed

Problem Water temperature is a critical component of trout habitat. Stream temperatures not only affect the distribution, behavior, and survival of trout (and other species), but also compel these species to move toward small areas of preferred temperatures, known as refuges, to maximize growth, survival, and fitness. The Schoharie watershed in the Catskill Mountains, including East Kill, West...

Trends in Nitrate Concentrations in Public Water-Supply Wells, Suffolk County, New York, 1982-2008

Introduction High nitrate concentrations are a common concern among many purveyors, including the Suffolk County Water Authority (SCWA), the largest supplier of water to residents in Suffolk County. Typically, the amount of nitrate in groundwater is related to land use, where the greatest concentrations are observed in agricultural regions. In many areas, the nitrate concentration has...

Monitoring of Waterways for Mosquito Insecticides, Suffolk County, New York

Introduction Mosquitoes are the principle vector of the West Nile Virus (WNV) which causes infections in humans and animals and has emerged as a public health threat throughout Long Island, NY. The WNV was first detected among birds and mosquitoes by the Suffolk County Department of Health Services (SCDHS) in 2000. In response to the public health concern, the USGS in cooperation with the SC...

Long-Term Monitoring of Buck Creek Watershed in the Western Adirondack Region of New York

Monitoring of lake chemistry in the western Adirondack region has indicated reductions in the acidity of these lakes during the past two decades. However, lakes are not always reliable indicators of streams and soils. Uncertainty remains regarding the recovery potential of surface waters and the effects of acidic deposition on soils. Furthermore, nitrogen, long considered a growth-limiting...

Simulation of migration of brine and saline water from the flooded Retsof salt mine in the Genesee Valley, New York

Problem - Roof collapses in the Retsof salt mine near Geneseo N.Y. in March and April of 1994 propagated upward through overlying bedrock, forming a 600-ft-long rubble zone or chimney that connected the mine to a glacial aquifer system and created sinkholes at land surface. Fresh water from the glacial aquifers flowed downward into the mine until the mine was completely flooded in January 1...

Estuarine Physical Response to Storms—Jamaica Bay

Problem Coastal communities are susceptible to damage from coastal storms and associated storm surge, and although tidal wetlands provide a buffer against shoreline erosion and aid in shoreline stabilization, they too are vulnerable to the action of storms. Tidal wetland dynamics need to be better understood, as they are also intrinsically valuable as nursery, feeding, and refuge areas for m...

The reservoir considered here consists of thin hydrate rich sandy layers interbedded with mud layers. Because of the input parameter uncertainties involved, it is prudent from a geomechanical perspective to estimate the likely...

Methane- and dissolved organic carbon-fueled microbial loop supports a tropical subterranean estuary ecosystem

Rapid 3-week transition from migration to incubation in a female Roseate Tern (Sterna dougallii)

A female Roseate Tern that staged in Puerto Rico on 10 May 2008 on its migration north was first observed in the nesting area at Bird Island, Buzzards Bay, Massachusetts on 21 May. It was incubating a complete clutch of two eggs by 1 June and likely had initiated laying within 20 days of having been in Puerto Rico.

Spatial mismatch between sea lamprey behaviour and trap location explains low success at trapping for control

Crucial to the management of invasive species is understanding space use and the environmental features affecting space use. Improved understanding of space use by invasive sea lamprey (Petromyzon marinus) could help researchers discern why trap success in large rivers is lower than needed for effective control. We tested whether manipulating...

Black shales of the Late Devonian to Early Mississippian Bakken Formation are characterized by high concentrations of organic carbon and the hyper-enrichment (> 500 to 1000s of mg/kg) of V and Zn. Deposition of black shales resulted from shallow seafloor depths that promoted rapid development of euxinic conditions. Vanadium hyper-...
