Distribution of Stratified-Drift Aquifers in the Glaciated Northeastern United States

A digital representation of a glacial aquifer map for the northeastern United States (Kontis and others, 2004; http://pubs.er.usgs.gov/publication/pp1415C; Plate 3) has been prepared by staff of the U.S. Geological Survey. Aquifer data was digitally compiled from a georeferenced version of Plate 3, along with supplemental aquifer maps that covered portions of the northeast.

Development of Long Island Water Quality Integrated Data System (LIQWIDS) - User interface and web services in support of collaboration under the Long Island Nitrogen Action Plan(LINAP)

PROBLEM There are more than 60 organizations and agencies collecting water-quality data on Long Island. The types of database management that are used to store and archive regulatory and non-regulatory data vary from paper forms to spreadsheets to State and Federal databases, and there is minimal communication between these systems. As a result, those interested in analyzing data may be unaware of what data exist and how those data can be obtained without a Freedom of Information Law request. A unified data sharing system that provides multiple levels of sensitive and non-sensitive data storage and dissemination is needed. This system should link the various databases and interact through web services to provide...

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 Kill, and Batavia Kill tributaries as well as the main-stem Schoharie Creek, supports small or transient populations of wild brook trout as well as naturalized and hatchery brown trout. Water temperatures in parts of these rivers typically exceed lethal thresholds for these species for several weeks each summer. Managing agencies...
