I am old enough to remember a time when most raptors within #Ontario and #GreatLakes region were rare indeed due to thin-shell syndrome from DDT. Seeing one was nearly miraculous, and I think this feeling still persists. I never saw a cormorant until I was in my 30s, but now they are so common that p…

Bald eagles nearly died out. What can we learn from their return to the southern Great Lakes?
The pesticide DDT nearly wiped out North America’s bald eagles. Communities, scientists and politicians worked hard to bring this symbolic bird back from the brink

PFAS is ubiquitous within the waters of the #GreatLakes basin, but there are also particular hot spots, which have led to fish consumption advisories. #contaminants #waterquality

Toxic ‘forever chemicals’ ubiquitous in Great Lakes basin, study finds
PFAS chemicals present in air, rain, atmosphere and water in basin, which holds nearly 95% of US freshwater

#Shipping is a vital industry on the #GreatLakes, but even in modern times, it can be a dangerous industry. These ships are quite large and undergo stresses on these very big maritime systems. Many of the "Laker" fleet like the Michipicoten, are older, upgraded and repurposed vessels, but …

With a practically ice-free year on the #GreatLakes, the water #temperatures to start June are incredibly high and likely to spike to record highs during the predicted hot summer. This will affect algal growth and the composition of food webs, but we don't yet know how this will manifest. Se…

To begin our #GreatLakes #plankton sampling, our research ship Limnos has to transit from Lake #Ontario to Lake #Erie
