title: Freshwater grab sampling of streams in the Kwakshua Watersheds of Calvert and Hecate Islands, BC: 2013-2019

description: This dataset contains the analytical results of freshwater biogeochemical samples collected on Calvert and Hecate Islands on the central coast of British Columbia, Canada, from April 2013 to December 2019. Samples were collected, approximately monthly, year round at the stream outlets of the seven largest watersheds, which are gauged as part of the Kwakshua Watersheds Observatory. The samples were analyzed for dissolved organic carbon (DOC) concentration and stable isotopes, particulate organic carbon and nitrogen (POC and PON) concentration and isotopes, dissolved organic matter (DOM) composition (via metrics of absorbance and fluorescence), total, dissolved, and inorganic nutrients, metals and major ions, water isotopes, and total suspended solids (TSS). Complimenting each water chemistry sample, we measured electrical conductivity, temperature, pH, oxidation reduction potential (ORP), and dissolved oxygen in-situ with a hand-held sensor.
description: From the Calvert Island field station, each stream was accessed by a short boat ride (~10 min). The field team was dropped on land and walked up-stream to the pre-established sampling location, above tidal influence. For most sample types, water was filtered streamside, using a 0.45 µm filter attached to a syringe. POC, PON, and TSS samples, however, were brought back to the laboratory, to be filtered via vaccum filtration, using a grade GF/F 0.7 µm filter. The samples were then preserved, according to the Hakai preservation protocol before being sent to external analytical laboratories for analysis. The absorbance and fluorescence samples as well as TSS samples were analyzed on site by Hakai technicians. 

The physio-chemical parameters were measured directly at the sampling locations, using the YSI probe (Pro Plus Multiparameter Instrument)
description: The resulting data were reviewed and flagged following our standard quality control (QC) procedures.

title: 2021 Synoptic Water Quality Study Data

description: The Synoptic Water Quality Study was initiated in 1980 by federal, provincial, and academic partners to monitor lake health in the Halifax Regional Municipality, Nova Scotia. The synoptic water quality surveys—measuring major ions, nutrients, pH, organic matter, and trace elements—have been conducted on a decadal basis on a set of ~50 lakes. This dataset contains the measurements collected during the 2021 sampling campaign.
description: Surface samples were collected via helicopter or boat from each of the study lakes on March 30, 2021. Variability in water chemistry within each lake was reduced by collecting surface samples in the early spring, immediately following ice-out, when lakes were mixing. Following collection, surface water samples were transported to a lab and divided, and the subsamples were either analyzed onsite or were delivered to commercial, government, and academic laboratories for immediate analysis. Each sample was measured for a standard set of water quality parameters. Quality control measures included replicate sampling in a subset of lakes and verifying agreement among replicates, as well as the collection of field blanks to assess procedural variability. Additionally, multiple surface samples were collected and compared for large lakes, and lakes having distinct basins.
description: Where multiple measurements were collected from a single study lake, the measurements were averaged. All questionable measurements were removed/flagged. Wherever measurements fell below the detection limit, half the detection limit was reported.

title: ELA LTER Discharge

description: Lake 239 is one of five reference lakes at the Experimental Lakes Area monitored as control lakes for other manipulation experiments. In recent years, the value of these lakes as whole ecosystem LTER observatories has become clear as signals arise from natural (forest fires, beaver dams, extreme weather) and anthropogenic (long-range pollutant deposition, climate change) sources.
description: Hydrometric measurements began on these stations in 1969 (Lake 239 Northwest Inflow) and 1971 (Lake 239 East and Northeast Inflow). Each station drains a forested and rocky basin that contributes to Lake 239. 

Each station uses a V-Notch weir with a water level recorder. Both weirs and recorders have been modified during the data set collection.

title: Slave River Spring Water Quality Sampling

description: In response to industrial wastewater leakage at the Kearl Oil Sands Mine in Alberta, GNWT-ECC in collaboration with the Fort Smith Métis Council, Town of Fort Smith, and Smith’s Landing First Nation initiated a precautionary water quality sampling program for the Slave River at Fort Smith in the spring of 2023.
description: Weekly water quality grab samples are being taken at the Town of Fort Smith water treatment plant and directly from the river near the town boat launch. Samples are being analyzed for general water quality, total and dissolved metals, polycyclic aromatic hydrocarbons (PAHs) and naphthenic acids.  Polyethylene membrane devices (PMDs) for PAHs and multiparameter water quality sensors (YSI EXO2s) in the Town of Fort Smith water intake building have also been deployed to measure some water quality parameters continuously.
description: In addition to lab quality control evaluations, the data was screened against data quality objectives through several automated validation procedures.  These included detection limit screening, detectable levels in field and travel blanks, relative percent differences for replicates and for total / dissolved metal ratios.  Spring values were also compared against long term water quality data sets at these locations and evaluated for outliers.

title: Executing a Long-Term Watershed Monitoring Plan for the West Fundy Composite Level 1 Watershed

description: Eastern Charlotte Waterways Inc. (ECW) created an integrated watershed management plan (2020). This plan utilized multiple parameters under three broad categories, biomonitoring, physiochemical, and hydromorphological, to assess the state of watersheds in New Brunswick. This project aims to assess the plan created by ECW to determine whether the chosen parameters and the staff, time, and equipment necessary to monitor those parameters achieve their purpose in the most efficient way possible. This project also aims to add one year of data to the baseline dataset for the West Fundy Composite level 1 watershed. Eleven sites were
monitored in the four major rivers in the West Fundy Composite level 1 watershed: the Magaguadavic River, Digdeguash River, Lepreau River, and New River. On each river, a site was established in the upper reaches, the mouth, and a central point in order to get an understanding of water quality in the largest portion of the river.
description: A YSI Professional Plus was utilized to measure basic water quality parameters (Dissolved oxygen, temperature, pH, conductivity) on a monthly basis. While taking the YSI measurements, a water sample was collected and tested at the ECW laboratory for Escherichia coli (E. coli) and total coliform levels. Metals and nutrient analysis was completed on a bi-monthly basis to assess seasonal changes in a full suite of metals and nutrients.

title: Thornton Creek Water Quality Monitoring Program

description: Thornton Creek Enhancement Society is a non-profit organization dedicated to sustaining and building salmon stocks in Barkley Sound, as well as facilitating educational and research opportunities. The objective of the Thornton Creek Water Quality Monitoring Program is to create quality, long-term datasets that can be used for research and stewardship by building partnerships with other local organizations and indigenous governments. The rivers that we enhance and/or monitor support critical salmon populations and are susceptible to logging, pollution, mining and human impacts. This makes gathering baseline data on the quality of these watersheds very important. The program periodically collects physio-chemical parameters at 8 sites throughout 7 Rivers that feed into Barkley Sound.

This program is made possible thanks to the support in part from the Department of Fisheries and Ocean and the Pacific Salmon Foundation, as well as the partnership with Toquaht Nation, Ucluelet First Nation and Redd Fish Restoration. This project is funded by donations to the Thornton Creek Enhancement  Society.
description: Data is collected at 8 sites every 28 days, year-round. A YSI probe 2030 (16E100523) is used to collect water temperature, dissolved oxygen, dissolved oxygen saturation, and conductivity. A thermometer is used to collect air temperatures and a LaMotte wide-range pH kit is used to determine pH. Field observations, such as weather and physical changes are recorded at every site visit.
description: Protocols have been put into place to ensure data collected is consistent and of high quality. Site descriptions, pictures, field markers and GPS coordinates that have been confirmed using Google Earth are provided for each monitoring site and used for site relocation. To ensure instruments are functioning properly, conductivity and dissolved oxygen calibrations are performed on the YSI probe 2030 (16E100523) 24 hours before every site visit and are kept on record. To help mitigate human errors,  field sheets are double checked by sampler for completeness, clarity, and data entry errors immediately after data is recorded. Parameters with unusually high differences are flagged.

title: CIMP 174: The Impacts of Recent Wildfires on Northern Stream Ecosystems

description: This study examines the impact of recent wildfire on freshwater streams within the North Slave, South Slave, and Dehcho regions of the Northwest Territories (Canada) through analysis of their water chemistry and benthic macroinvertebrate assemblages. Benthic macroinvertebrates, or the macroscopic organisms living within/on the substrate of these streams, were sampled following methodologies outlined by the Canadian Aquatic Biomonitoring Network (CABIN). Biological indices (ex. EPT) were calculated and compared statistically to determine relationships regarding benthic diversity and abundance. Results of this study suggest that recent wildfires cause at minimum short-term perturbations in water quality, such as increased turbidity and TSS. In addition, results indicate slight structural changes in invertebrate communities of burned streams compared to unburned streams, including increased richness and abundance of collector-gatherer taxa. This dataset contains water quality data from 21 streams across the South Slave, and Dehcho regions. This project is funded by the Cumulative Impact Monitoring Program (project 174).
description: Four stream water samples were collected per site for analysis of general physical parameters (including alkalinity, conductivity, TSS, TDS, turbidity, and pH), nutrients, total dissolved metals, and trace elements. One of four samples collected from each site was treated immediately with nitric acid (HNO3) to prevent precipitation of metals into their oxide components and adsorption to container walls prior to total metal concentration analysis. Water samples were stored in a cool, dark place until their submission to the Taiga Environmental Laboratory in Yellowknife, Northwest Territories. Taiga Environmental Laboratory is accredited by the Canadian Association for Laboratory Accreditation to ISO/IEC 17025 standards.
