Distilling Science at the Experimental Lakes Area: Acoustic imaging
This video highlights the use of hydroacoustic imaging technology at the Experimental Lakes Area (ELA), a unique freshwater science research facility in northwestern Ontario, Canada.
For over 45 years, scientists have been using the ELA to conduct whole-ecosystem experiments in a freshwater setting, amassing one of the largest and most complete datasets in the world on long-term changes in small lakes. The ELA has been a testing ground for hydroacoustic technology, helping scientists to fine-tune methods that allow them to quickly survey the health of lakes. With the ELA’s network of 58 freshwater lakes and the ability of scientists to design experiments for entire lakes and even for small watersheds, this unique research station is one of the few locations in the world where technology like hydroacoustic imaging can be calibrated in a natural setting.
In April 2014, IISD took over management of the ELA. Distilling Science at the Experimental Lakes Area is an IISD-produced short video series.

Canadian Exporters Face New Reporting Costs as Carbon Border Taxes Multiply
The European Union’s carbon border tax will add new compliance costs for Canadian businesses that trade certain products, especially steel and aluminum, to the bloc. The increased costs—linked to differing demands for measuring, reporting, and verifying a product’s greenhouse gas emissions across the growing number of countries adopting border carbon adjustment (BCA) mechanisms—“make it tough for any exporter to those markets,” Aaron Cosbey, senior associate at the International Institute for Sustainable Development (IISD), told The Energy Mix.
