Major ions data consist of the following key ions in precipitation: Cl-, NO3-, SO4=, NH4+, Na+, K+, Ca++, Mg++. The data sets typically also include the pH and depth of the precipitation sample. These data are collected by several provincial, national and bi-national networks. The wet-only...

The datasets and maps are associated with a research study. Annual total (dry + wet) deposition fluxes of nitrogen (nitric acid, nitrate and ammonium) and sulfur (sulfur dioxide and sulfate) were determined at 15 Canadian Air and Precipitation Monitoring Network (CAPMoN) sites from 2000 to 2018....

Water quality monitoring data collected in priority tributaries to provide nutrient concentration data to estimate nutrient loads to the waters of the Great Lakes. Data is collected to advance the science to understand and address the complex problem of recurrent toxic and nuisance algae in the...

Water quality and suspended sediment monitoring and surveillance data collected from the connecting channels of the Great Lakes to determine baseline water quality status, long term trends and spatial distributions, the effectiveness of management actions, determine compliance with sediment...

Water quality and ecosystem health data collected in the Great Lakes and priority tributaries to determine baseline water quality status, long term trends and spatial distributions, the effectiveness of management actions, determine compliance with water quality objectives and identify emerging...

Ambient air is sampled daily, with a nominal 24-hour sampling period, on a Canadian Air and Precipitation Monitoring Network (CAPMoN) sequential sample head located 10 meters above ground. Air is drawn through a three-stage filter pack consisting of 47-millimeter Teflon, nylon and cellulose...

Precipitation samples are collected at a number of sites in Alberta by Alberta Environment and Parks. Samples are analyzed for select cations and anions as well as pH. Samples are collected weekly using an event-only precipitation sampling protocol. The specific monitoring objectives are to: (1)...
