Lake Ontario Research Study

March 1, 2017
Category: News

The City of Hamilton, University of Toronto and Hoskin Scientific are among a long list of partners involved in a local environmental research study.

Grad students from U of T use some of the most sophisticated tools to aide in their water analysis. The HSPALink 2-Way Logging Transmitter and the EXO2 Sonde with Total Algae Sensor are the instruments of choice when it comes to routine water quality testing.

A member of our staff was on-site at the local pumping station to facilitate training for the EXO2. Raw water from Lake Ontario is drawn in by this facility and subsequently treated to the highest standards in order to be safe, potable, drinking water for the local community. The research study aims to log and test the raw water in an effort to learn more about naturally occurring algae and other native species found in Lake Ontario.

The pictures below offer you a glimpse inside the pumping station.

Collecting Acoustic Stationary and Moving Boat Discharge Data

From SonTek:

You might have heard about some of the big upgrades to the powerful, multi-frequency RiverSurveyor-M9, but we didn’t want you to take our word for it – the proof is in the data – and we want to share examples on how RiverSurveyor 4.0 has dramatically simplified the data collection process for hydrologists and water monitoring specialists like you!

Watch as SonTek’s Product Manager/Application Engineer Isaac Jones and Senior Hydrologist, Daniel Wagenaar highlight how RiverSurveyor 4.0 has improved work-flow processes for water monitoring agencies, such as the USBR and EC. They also go over new features to include:

  1. No tagline/tape measure required: With RiverSurveyor Stationary Live, automatically measure distance between stations with DGPS or RTK GPS equipped systems.
  2. Manual configuration: Now you can set blanking distance, cell size and number of cells for moving boat measurements.
  3. Real-time QA/QC warnings: Know when there could be a problem before there is one.
  4. Zipped files: New and improved compression and auto-decompression, providing faster access to large amounts of data.
  5. Sample filter: Remove your random velocity outliers with ease!

See the SonTek collection here. And, as always, if there’s something you would like to see or can’t find on our site, don’t hesitate to call or email us. We’re happy to help!

From SonTek (YSI): The Pressure is ON!

December 16, 2016

Now available: Built-in pressure sensor option with the FlowTracker2!

sontek-flowtracker2Sontek writes:

With advances in technology and general application know-how contributed by world-renowned hydrologists, researchers and scientists, SonTek is pleased to unveil the new FlowTracker2 now with optional pressure sensor feature! Here is how the FT2 with pressure sensor can optimize your data collection efforts:

1) More accurate and precise measure of depth.

2) More accurate and precise positioning of sensor at proper depth for measurement.

3) Ability to measure in places where sight-reading of depth on a rod is inconvenient or impossible. Get spot-on depth measurements from bridges, walkways, manholes, or other structures.

4) Elimination of chance of human error when depth is manually read on the rod (source of error) and then keyed-in (another source of error). Ensure high quality data in spite of distracting conditions, cold weather, or personnel in training.

5) Ability to review and QA/QC depth time series data back at the office. Ensure manager visibility over field procedures and more rigorous data review options.

6) SonTek’s innovative patent-pending method of properly compensating pressure readings under different flow conditions. Ensures a real, useable, high-quality solution in the field, across different flow conditions.
