A Simple Web-Based Tool To Compare Freshwater Fish Data Collected Using Afs Standard Methods, Scott A. Bonar, Norman Mercado-Silva, Matt Rahr, Yuta T. Torrey, Averill Cate Jr. Jan 2015

A Simple Web-Based Tool To Compare Freshwater Fish Data Collected Using Afs Standard Methods, Scott A. Bonar, Norman Mercado-Silva, Matt Rahr, Yuta T. Torrey, Averill Cate Jr.

United States Geological Survey: Staff Publications

The American Fisheries Society (AFS) recently published Standard Methods for Sampling North American Freshwater Fishes. Enlisting the expertise of 284 scientists from 107 organizations throughout Canada, Mexico, and the United States, this text was developed to facilitate comparisons of fish data across regions or time. Here we describe a user-friendly web tool that automates among-sample comparisons in individual fish condition, population length-frequency distributions, and catch per unit effort (CPUE) data collected using AFS standard methods. Currently, the web tool (1) provides instantaneous summaries of almost 4,000 data sets of condition, length frequency, and CPUE of common freshwater fishes collected …


Synoptic Patterns Associated With Northeast And South East Ice Storms, Ricardo Vargas Jan 2015

Synoptic Patterns Associated With Northeast And South East Ice Storms, Ricardo Vargas

Dissertations and Theses

Wintertime storms that produce precipitation events such as snow, freezing rain, and ice pellets cause significant damage to utility services and disrupt travel. These synoptic systems involve deep isothermal regions where warm, moist air over-runs surface sub-freezing air. Much attention has been focused on Northeast ice storms, where a study by Cortinas et al. (2004) identified the Northeast as the region with the highest spatial distribution of freezing rain and ice pellets. Castellano (2012) also identified 2 types events where ice storms occur in the Northeast as a result of cold-air intrusions from Canada and from an absence of cold …
