Describing life sub-surface

Here's a bit more information from Andi's article previously quoted.

...the waters of the Bay of Fundy lie somewhere between two extremes in temperature, tropical and arctic, the region harbors an unusual mixture of creatures, drawn to the plant and animal plankton that thrive in its nutrient-rich waters.

While such marine life may be present in large quantities, it can still be hard to find. The green-tint that results from the abundance of phytoplankton can result in poor underwater visibility.

Photographer, Scott Leslie has witnessed the devastating impact that fishing trawlers have had on the ecosystem. “You’ll be swimming along in this gorgeous rich habitat then all of the sudden it becomes this desert,” caused by trawlers scouring the seafloor, he says. In this regard, Leslie’s images serve to educate and instill a deep appreciation of the richness of life not far from our shores and remind us of all we have to lose.
