Interactive Data

An integral part of the research at IISD Experimental Lakes Area focuses on Lake 239, which is one of the best studied lakes in the world.

The first temperature profile on Lake 239 was performed on November 9, 1968, and this lake has since turned into our richest dataset. One of the reasons that this lake is so important is because it has not been manipulated in any way, so any changes we see in the lake are a product of natural variation and atmospheric change.
