Water-Surface Profiles and Discharges for Four Stream Reaches, Ithaca, Tompkins County N.Y.

Background / Problem – The City of Ithaca, Tompkins County, N.Y., is in the process of developing a flood management plan for the streams that flow through the City. Flooding in the City is caused by a variety of distinct and sometimes interconnected reasons. Flooding often is a result of snowmelt and rain during the winter and spring. Slow ice-melt and breakup can lead to ice jams and...

Rockland County Water-Resource Assessment

INTRODUCTION • Concerns over the viability of the fractured bedrock aquifer that provides about 1/3 of Rockland County’s water supply prompted a 5-year study by the U.S. Geological Survey (USGS) to (1) define the hydrogeologic framework of the aquifer, (2) assess conditions within it, and (3) identify other potential sources of water for the County. The study was done in cooperation with...

Geohydrology of the Valley-Fill Aquifer in Upper Buttermilk Creek/Danby Creek Valleys, Town of Danby, Tompkins County, New York

Problem - The valley-fill deposits in Upper Buttermilk Creek/Danby Creek valleys are sources of water for many homeowners, farms, and small businesses that are in this valley. The aquifer was mapped by Miller (2000) and identified as one of the 17 aquifers in Tompkins County that needs to be studied in more detail. However, there is little geohydrologic data in the valley. A cluster of wells...

Geohydrology of the Upper Sixmile Creek/West Branch Owego Creek Valleys and Lower Sixmile Creek/Willseyville Creek Valleys, Town of Caroline, Tompkins County, New York

Problem - The Town of Caroline needs geohydrologic data in two major valley-fill aquifers within the town in order for planners to develop a strategy to manage and protect their water resources. Interest in the interaction between ground water and surface water has increased in recent years as a result of widespread concerns related to water supply. The need to better understand how the...

Statewide Assessment of New York’s Karst Aquifers With an Inventory of Closed-Depression and Focused-Recharge Features

Background: The New York State Departments of Environmental Conservation (NYS DEC) and Health (NYS DOH) are concerned about groundwater contamination in the carbonate-bedrock aquifers in New York, especially relating to the unintended introduction of volatile organic compounds (VOCs) and liquid manure to these aquifers. These carbonate rocks form extensive aquifers that transmit, and can yield...

Hydrogeologic Recharge Settings of the Carbonate-Bedrock Aquifers in Livingston and Monroe Counties, Western New York

Background: A sequence of gently dipping carbonate bedrock - the Bertie Formation, Akron Dolostone, and Onondaga Limestone crop out along a 2- to5-mile wide band in western and central New York. These bedrock units trend east-west for 250 miles across the State and form extensive carbonate-bedrock aquifers which transmit and yield water from solution-enlarged fractures, bedding planes, and...

Flood-inundation mapping of Egypt Creek, Dryden, Tompkins County

Problem – Flooding is an annual problem along Egypt Creek in Dryden. Increased runoff from expanding development, sediment clogged channels, and undersized culverts that cannot convey increased flows contribute to the problem. Flood maps for extreme floods are available through the effective FEMA flood insurance study (FEMA, 1978), but these maps, which became effective in 1979, are considered...

Hydrogeology and Water Quality of the North Shore Aquifer in Locust Valley, Town of Oyster Bay, New York

Problem Perchlorate detected in a shallow supply well within the southern portion of the Locust Valley Water District (LVWD) has prompted interest in determining the possible existence of a deeper confined aquifer (North Shore Aquifer) that may be protected from shallow contamination (fig. 1). Previous USGS studies in this area indicate the northern part of Nassau County has a complex...

New York Nowcast, Recreational Beaches of New York

Problem – Currently, swim advisories or closings are issued by beach managers based on standards for concentrations of bacterial indicators such as Escherichia coli (E. coli). Standard culture methods for these bacteria take at least 18-24 hours before results are available. At most Great Lakes beaches, the beach is posted with an advisory or closing or is determined to be acceptable for...

Urban Waters Initiative – BRONX & HARLEM RIVERS

Problem Over the past century, the Harlem River watershed has become highly urbanized with 90 percent of the waterway constrained by infrastructure, which has limited access for recreational use. Bound by New York (Manhattan) and Bronx Counties, the Harlem River is a tidal strait between urbanized estuaries to the north (Hudson River) and south (East River). Direct inputs include the more...

Final report for climate effects on the culture and ecology of sugar maple

Maple syrup is produced from the sap of sugar maple trees collected in the late winter and early spring. Native American tribes have collected and boiled down sap for centuries, and the tapping of maple trees is a cultural touchstone for many people in the northeast and Midwest. Because the tapping season is dependent on weather conditions, there...

Post-spring migration colony-site prospecting by Roseate Terns (Sterna dougallii)

We recorded banded Roseate Terns (Sterna dougallii) and unbanded individuals mated to banded individuals in May and the first third of June in 2001 and 2002 to quantify post spring migration prospecting by this species at Falkner Island, Connecticut, USA. In 2001, more than one quarter: 34/125 (27.2%) of those observed by 19 May and 38/150 (25.3...

Icebergs in the Nordic Seas throughout the Late Pliocene

The Arctic cryosphere is changing and making a significant contribution to sea level rise. The Late Pliocene had similar CO2 levels to the present and a warming comparable to model predictions for the end of this century. However, the state of the Arctic cryosphere during the Pliocene remains poorly constrained. For the first time we combine...

Rapid, remote assessment of Hurricane Matthew impacts using four-dimensional structure-from-motion photogrammetry

Timely assessment of coastal landforms and structures after storms is important for evaluating storm impacts, aiding emergency response and restoration, and initializing and assessing morphological models. Four-dimensional multiview photogrammetry, also known as structure from motion (4D SfM), provides a method for generating three-dimensional...

Implicit decision framing as an unrecognized source of confusion in endangered species classification

Legal classification of species requires scientific and values‐based components, and how those components interact depends on how people frame the decision. Is classification a negotiation of trade‐offs, a decision on how to allocate conservation efforts, or simply a comparison of the biological status of a species to a legal standard? The answers...

Reestablishing a host–affiliate relationship: Migratory fish reintroduction increases native mussel recruitment

Co‐extirpation among host–affiliate species is thought to be a leading cause of biodiversity loss worldwide. Freshwater mussels (Unionida) are at risk globally and face many threats to survival, including limited access to viable host fish required to complete their life history. We examine the relationship between the common eastern elliptio...

Bat community response to silvicultural treatments in bottomland hardwood forests managed for wildlife in the Mississippi Alluvial Valley

On the reliability of N‐mixture models for count data

N‐mixture models describe count data replicated in time and across sites in terms of abundance N and detectability p. They are popular because they allow inference about N while controlling for factors that influence p without the need for marking animals. Using a capture–recapture perspective, we show that the loss of information that results...

Transient coastal landscapes: Rising sea level threatens salt marshes

Salt marshes are important coastal environments that provide key ecological services. As sea level rise has accelerated globally, concerns about the ability of salt marshes to survive submergence are increasing. Previous estimates of likely survival of salt marshes were based on ratios of sea level rise to marsh platform accretion. Here we took...
