State of the Aquifer, Long Island, New York

Groundwater is among the Nation's most important natural resources. Nationwide it provides half of our drinking water and is essential to the vitality of agriculture and industry, as well as to the health of rivers, wetlands, and estuaries throughout the country. On Long Island groundwater is the sole source of fresh water for over 2.6 million people.

Delineation of the Saltwater-Freshwater Interface at Selected Well Locations in the Town of Riverhead, NY

Problem The Town of Riverhead in the northeastern Suffolk County includes rural farmland and suburbs and is bounded by the Long Island Sound to the north and Peconic Bay to the southeast. Riverhead’s close proximity to saline embayments and its location along the northeastern discharge area for Long Island’s groundwater flow system makes it vulnerable to saltwater intrusion. Several public-...

Mohawk River Ice Jam Monitoring

The Mohawk River near Schenectady, NY is prone to ice jams during periods of river-ice break-up. Ice jams in this reach typically form at channel constrictions, bridge piers, lock and dam structures, and sections with a reduced floodplain (Foster and others, 2011). Ice jam related flooding can result from backwater associated with the jam or from water released downstream when a jam fails....

Estimation of Density and Abundance of Biological Populations on National Parks and Wildlife Refuges Through Distance Sampling

The Challenge: Assessing the status and trends of populations of biological organisms is an important management goal and a recurrent theme in USGS research. Often, the most basic question of “how many are there?” remains elusive, thus making management decisions more difficult. This study continues a long-term commitment of technical support for the use of distance sampling for wildlife...

Warning buoy

A buoy warning of the under-bay sewage treatment plant pipeline appears to guide the AUV on its course; confirming that the AUV’s position is accurate. The AUV uses a differential global positioning system (GPS) receiver and bottom-tracking Doppler velocimetry log (DVL) to maintain position.
