In Delaware, there are approximately 140 water quality monitoring sites in Piedmont, Delaware Bay, Chesapeake Bay, and Inland Bay drainage basins. Long-term quarterly (i.e., four times a year: Q1\u2014January\u2013February\u2013March; Q2\u2014April\u2013May\u2013June; Q3\u2014July\u2013August\u2013September; Q4\u2014October\u2013November\u2013December) water temperature data were calculated from each water quality monitoring sites\u2019 continuous monthly data. This study focuses on water quality monitoring sites with significant (p-value identifying linear regression model) increasing or decreasing trends of water temperature. Quarterly water temperature data, statistical analysis, and maps showing increasing and decreasing trend from water quality monitoring sites with significant trends are presented in this article.<\/jats:p>","DOI":"10.3390\/data6080079","type":"journal-article","created":{"date-parts":[[2021,7,25]],"date-time":"2021-07-25T22:06:21Z","timestamp":1627250781000},"page":"79","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Temporal Changes in Delaware Waters Using Long-Term (1967\u20132019) Water Temperature Data"],"prefix":"10.3390","volume":"6","author":[{"given":"Bhanu","family":"Paudel","sequence":"first","affiliation":[{"name":"Delaware Department of Natural Resources and Environmental Control, Division of Watershed Stewardship\/Watershed Assessment and Management Section, 285 Beiser Blvd., Suite 102, Dover, DE 19904, USA"}]},{"given":"Lori M.","family":"Brown","sequence":"additional","affiliation":[{"name":"Delaware Department of Natural Resources and Environmental Control, Division of Watershed Stewardship\/Watershed Assessment and Management Section, 285 Beiser Blvd., Suite 102, Dover, DE 19904, USA"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,24]]},"reference":[{"key":"ref_1","unstructured":"(2003).
