Summary

This data set provides locations and values of water quality parameters from a survey conducted on August 25, 2016 using an Autonomous Underwater Vehicle (AUV) in Nicoll Bay, NY. During the August 25 survey, 12,275 observations of water quality parameters were made. Parameters collected include dissolved oxygen, pH, water temperature, specific conductance, and salinity. Data was collected in approximately east-west transects by the AUV, with the northern-most transects made first. Data was collected between the hours of 1 am and 5 am to obtain minimum DO values in the daily cycle. There are three files available for download in the 'Attached Files' section below. There is a zip file which contains the observation locations and water [...]

Purpose

These data were collected to provide support for decisions regarding coastal resource management. Hard clam restoration projects performed in Great South Bay have typically yielded unsuccessful results. It is thought that low dissolved oxygen levels in the bay could be a limiting factor in ecosystem development. Thus, a spatial survey of dissolved oxygen was necessary in this region to provide a baseline of DO availability and support the New York State Dept. of Environmental Conservation Waterbody Inventory and Priority Waterbodies List. This survey provides the spatial distribution of water quality parameters, and is meant to be used in conjunction with existing data that provides time related components.
