Program to Maintain and Update Groundwater Models

The Model Maintenance program, in cooperation with the N.J. Department of Environmental Protection (NJDEP), archives, maintains, updates, and shares groundwater-flow models that have been developed by the New Jersey Water Science Center (NJWSC). The program was started in 1995 to maintain existing groundwater flow models, use standardized procedures to archive the models, update...

Predictive Modeling of Bacteria Concentrations at Presque Isle State Park, Erie, Pennsylvania

Approximately 7 miles of Lake Erie shoreline lies within Presque Isle State Park in Erie, Pa. Monitored public bathing beaches at Presque Isle make up less than 1 mile. Concentrations of Escherichia coli (E. coli) at monitored beaches in Presque Isle State Park occasionally exceed the single-sample bathing-water standard of 235 colonies per 100 milliliters resulting in potentially unsafe...

Evaluation of Water-Supply Issues

The NJ Coastal Plain RASA (Regional Aquifer System Analysis) model (in this document referred to simply as “the RASA model”) is one of the most widely used models by hydrologists in the NJWSC.  This model was developed as part of the RASA program, which was started in 1978 after a congressional mandate to develop quantitative appraisals of the major groundwater systems of the United States....

New England WSC Seminar series Vogel 20170201

Over half a century ago, the Harvard Water Program introduced the field of operational or synthetic hydrology, providing stochastic streamflow models (SSMs) which could generate equally likely synthetic streamflow traces useful for hydrologic risk management. This presentation advances the modern equivalent of SSMs, termed ‘stochastic watershed models’ (SWMs), which could provide useful input...

Do Neonicotinoid Pesticide Seed Coatings Pose a Hazard to Seed-eating Birds?

Treating or “dressing” of seeds with pesticides is a commonly used method to enhance crop yield in agriculture.  Regrettably, such treated seeds can be ingested by wildlife, and depending on the extent of exposure, can cause adverse effects.

A Native Earthworm Accumulates Extraordinarily High Concentrations of Lead

The Challenge: As a rule, plants and animals contain lower concentrations of lead than are present in soils that support them. Lead does not biomagnify along trophic levels in ecosystems but instead remains relatively immobile in soil. The exposure of wildlife to soil lead depends mainly on the incidental ingestion of soil. The native earthworm, Eisenoides lonnbergi, is anomalous in its...

Why Do We Band Birds?

Bird banding data are useful in both scientific research and management and conservation projects. Individual identification of birds makes possible studies of dispersal and migration, behavior and social structure, life-span and survival rate, reproductive success and population growth.

Hydrologic Effects of Pymatuning Earthquake

Within hours after the Pymatuning earthquake of September 25, 1998, in northwestern Pennsylvania, local residents reported wells becoming dry, wells beginning to flow, and the formation of new springs. About 120 household-supply wells reportedly went dry within 3 months after the earthquake. About 80 of these wells were on a ridge between Jamestown and Greenville, where water-level declines of...

Survival and Recruitment of Common Eiders in the Gulf of Maine

The dresseri race of common eiders breed from central Labrador to southern Maine and winter from Newfoundland to Massachusetts. The breeding population in the mid-1980s was estimated to be 71,000 pairs, of those 40% were in Maine. In Maine, nesting eiders increased from a few pairs in the early 1900s to approximately 28,000 pairs in 1989. Although the number of birds seems to be stable, the...

Modelling sound attenuation in heterogeneous environments for improved bioacoustic sampling of wildlife populations

Acoustic sampling methods are becoming increasingly important in biological monitoring.

Latitudinal limits to the predicted increase of the peatland carbon sink with warming

The carbon sink potential of peatlands depends on the balance of carbon uptake by plants and microbial decomposition. The rates of both these processes will increase with warming but it remains unclear which will dominate the global peatland response. Here we examine the global relationship between peatland carbon accumulation rates during the...

Advantages and limitations to the use of optical measurements to study sediment properties

They are useful for estimating suspended mass concentration as well as particle-related properties such as size, composition, packing (particle porosity or density), and settling velocity. Measurements of optical properties are, however,...

Monitoring responses to variation in food supply for a migratory waterfowl: American Black Duck (Anas rubripes) in winter

Wintering Black Ducks (Anas rubripes) concentrate in wetlands along the Atlantic coast where natural and anthropogenic disturbances have increased over the last 50 years, a period in which the population of Black Ducks has declined. We studied the sensitivity of Black Ducks to perturbations in food supply that often result from disturbances by...

Evidence that climate sets the lower elevation range limit in a high‐elevation endemic salamander

A frequent assumption in ecology is that biotic interactions are more important than abiotic factors in determining lower elevational range limits (i.e., the “warm edge” of a species distribution). However, for species with narrow environmental tolerances, theory suggests the presence of a strong environmental gradient can lead to persistence,...

Linking otolith microchemistry and surface water contamination from natural gas mining

Unconventional natural gas drilling and the use of hydraulic fracturing technology have expanded rapidly in North America. This expansion has raised concerns of surface water contamination by way of spills and leaks, which may be sporadic, small, and therefore difficult to detect. Here we explore the use of otolith microchemistry as a...
