Water Quality - Tuktut

Water Quality - Tuktut This dataset is a collection of measurements which make up two water quality indexes: Nutrients, Physical and Major Ions (NPMI) Index and Metals Index. The measurements are taken at two different locations along the Hornaday River annually in early-July. Project Rationale: Water quality is a widely used measure for assessing and monitoring the condition of freshwater ecosystems. The chemical composition of water influences the biological productivity and species composition of rivers. Changes in the water quality in the rivers and creeks in the Western Arctic can act as early indicators of ecosystem change. The presence of contaminants, such as persistent organic pollutants (POPs), heavy metals, and radionuclides are a concern because they can have negative effects on Arctic ecosystems and human health. Furthermore, a changing climate in the Arctic can influence the nutrient levels in the streams and rivers as more nutrients will be released from thawing permafrost. As the expected effects of climate change on Arctic ecosystems are still unknown, continuous monitoring is paramount. 2018-04-19 Parks Canada Jay.frandsen@pc.gc.ca Nature and EnvironmentTuktut Nogait National Parkwater qualityecological integrityHornaday Riverheavy metalsnutrientsphysical and major ionsclimate change Water Quality - Tuktut - HRE - Dissolved Metals - 2000-2017 - data - 1CSV https://124gc.sharepoint.com/:x:/s/external/_layouts/15/download.aspx/EWv1btdlIllAjbLvz7sltvcBVOmOh971UANlMYthnS2Pvw?e=ppTf9R Water Quality - Tuktut - HRE - Total Metals - 2000-2017 - data - 2CSV https://124gc.sharepoint.com/:x:/s/external/_layouts/15/download.aspx/Ed_UBPBDgllMsXrv62UWexwBl0CC9vUO9O0M-_5V__HPMw?e=VItCWn Water Quality - Tuktut - LHR- Dissolved Metals - 2000-2017 - data -3CSV https://124gc.sharepoint.com/:x:/s/external/_layouts/15/download.aspx/Ebff3c4DyzNEjHC21qDcIWAB8n2I5H14CEOVG8tduVAW2w?e=xpDEIv Water Quality - Tuktut - LHR - Total Metals - 2000-2017 - data - 4CSV https://124gc.sharepoint.com/:x:/s/external/_layouts/15/download.aspx/EYtw-XoiEThJvmDfnMRkk6ABMFV3YnC27PTXYfpQhb2AKQ?e=lecBp5 Water Quality - Tuktut - LHR - Nutrients, Physicals ,and Major Ions - 1998-2017 - data - 5CSV https://124gc.sharepoint.com/:x:/s/external/_layouts/15/download.aspx/EVWtGIF_QhtLuJkiAxjhfbYBaigN27ywNBczFG2EAzkDpg?e=WEgQWg Water Quality - Tuktut - HRE - Nutrients, Physicals ,and Major Ions - 1998-2017 - data - 6CSV https://124gc.sharepoint.com/:x:/s/external/_layouts/15/download.aspx/EX-V4rA81gFJlf-AKVAzuUIBnSv7iDaq_4m5VIXhossSIQ?e=xFygP5 Water Quality - Tuktut - 1998-2017 - data dictionaryCSV https://124gc.sharepoint.com/:x:/s/external/_layouts/15/download.aspx/EQpnZ7fYvfRLgp9zpA14qb8B1CbjKEmKQhyT6g7VCVsYaw?e=8nCj1O
