IAN Seminar Series 2014

The goal of the IAN seminar series is to provide concise, thought-provoking ideas relating to Chesapeake Bay science and management. Short presentations (15 minutes maximum length) are immediately followed by a lunchtime discussion of the topics raised by the presenter. The discussion is summarized and is posted along with a pdf version of the seminar slides. The seminars are captured on video and posted under a Creative Commons license so they can be freely shared.

Sampling & Data Analysis: Single vs. Multiple Threshold Scoring - Ron Melcer (CRA) - IAN Seminar Series
2011-10-25T12:00:00-04:00 2011-10-25T13:00:00-04:00
Macknis Room, Chesapeake Bay Program Office, 410 Severn Avenue (Suite 109), Annapolis MD
The Chester is a river on the northern part of the Chesapeake Bay. It has twenty sites that test depth, temperature, and salinity, conductivity, turbidity, and Secchi, a method of judging water quality based on the depth of the water in which the light from the surface reaches. In more recent years, Secchi scoring has recently been reported in the Chester River based on more in-depth testing, using multiple percent thresholds. By using multiple data points from tests that are done over time, an area is given an average water quality score. This is opposed to the former, single threshold method, in which a score is given based on one threshold that is decided at the beginning of the experiment.

Abstract

The Chester is a river on the northern part of the Chesapeake Bay. It has twenty sites that test depth, temperature, and salinity, conductivity, turbidity, and Secchi, a method of judging water quality based on the depth of the water in which the light from the surface reaches. In more recent years, Secchi scoring has recently been reported in the Chester River based on more in-depth testing, using multiple percent thresholds. By using multiple data points from tests that are done over time, an area is given an average water quality score. This is opposed to the former, single threshold method, in which a score is given based on one threshold that is decided at the beginning of the experiment.
