Abstract:

This dataset contains environmental sampling data associated with CARMMHA 2018 trawling efforts targeting fish and crustaceans. Field biologists collected environmental samples concurrent with efforts to collect dolphin prey using trawls from 2018-07-06 to 2018-10-12. Environmental water quality measurements were done at each trawl station in Mobile Bay, Alabama, Barataria Bay, Louisiana, and in the waters near Dauphin Island, Alabama in the summer of 2018. The dataset includes sampling collection site, location (latitude, longitude), date, time, water temperature, salinity, dissolved oxygen, water depth, and sample depth at which water quality measurements were collected.
