Use of, Satisfaction with, and Requirements for In-Situ Turbidity Sensors.

Abstract

This study was conducted for the Alliance for Coastal Technologies (ACT) to gather data about the use of in-situ turbidity sensors. The study entailed a telephone survey of professionals in the coastal resources field, such as biologists, researchers, and coastal managers, who are currently involved in measuring turbidity in coastal and near-coastal waters. The telephone survey questionnaire was developed cooperatively by Responsive Management and the ACT. Responsive Management conducted a pre-test of the questionnaire, and revisions were made to the questionnaire based on the pre-test.

Interviews were conducted Monday through Friday from 9:00 a.m. to 9:00 p.m., Saturday noon to 5:00 p.m., and Sunday from 3:00 p.m. to 9:00 p.m., all local time. The survey was conducted in April and May 2005. Responsive Management obtained a total of 50 completed interviews. The software used for data collection was Questionnaire Programming Language 4.1. The analysis of data was performed using Statistical Package for the Social Sciences software as well as proprietary software developed by Responsive Management.
