Advanced methods for modeling water-levels and estimating drawdowns with SeriesSEE, an Excel add-in
Keith Halford, C. Amanda Garcia, Joe Fenelon, Benjamin B. Mirus
2012, Techniques and Methods 4-F4
Water-level modeling is used for multiple-well aquifer tests to reliably differentiate pumping responses from natural water-level changes in wells, or “environmental fluctuations.” Synthetic water levels are created during water-level modeling and represent the summation of multiple component fluctuations, including those caused by environmental forcing and pumping. Pumping signals are modeled...

Emmanuel G. Charles, Robert S. Nicholson
2012, Scientific Investigations Report 2012-5122
The Kirkwood-Cohansey aquifer system is an important source of present and future water supply in southern New Jersey. Because this unconfined aquifer system also supports sensitive wetland and aquatic habitats within the New Jersey Pinelands (Pinelands), water managers and policy makers need up-to-date information, data, and projections that show the...
Comparison of five modelling techniques to predict the spatial distribution and abundance of seabirds
Allan F. O’Connell, Beth Gardner, Steffen Oppel, Ana Meirinho, Iván Ramírez, Peter I. Miller, Maite Louzao
2012, Biological Conservation (156) 94-104
Knowledge about the spatial distribution of seabirds at sea is important for conservation. During marine conservation planning, logistical constraints preclude seabird surveys covering the complete area of interest and spatial distribution of seabirds is frequently inferred from predictive statistical models. Increasingly complex models are available to relate the...

Comparing seasonal dynamics of the Lake Huron zooplankton community between 1983-1984 and 2007 and revisiting the impact of Bythotrephes planktivory
David B. Bunnell, Kevin M. Keeler, Elizabeth A. Puchala, Bruce M. Davis, Steven A. Pothoven
2012, Journal of Great Lakes Research (38) 451-462
Zooplankton community composition can be influenced by lake productivity as well as planktivory by fish or invertebrates. Previous analyses based on long-term Lake Huron zooplankton data from August reported a shift in community composition between the 1980s and 2000s: proportional biomass of calanoid copepods increased while that of cyclopoid copepods...
