We seen smaller kills in Western LI Sound simply resulting from hot weather (= less dissolved oxygen). Wonder what the combination of hot weather and skeevy water would do.

Mostly extensive open untreated sewer runoff, rain sewer overflow, leaking septic systems, fertilizer / lawn care runoff, and I even heard washing boats at the marinas..
That coupled with relatively calmer waters, very hot temps has effed large areas of the bay by supercharging the algae which then disolves the oxygen when the algae "respires" in bio terms, whatever that means, but I'm guessing that it's cyclical over the course of day night as the algae dies off in the sun and then reinvigorates itself on the oxygen and nutrients at night.
The bay looks silver gray from the lack of oxygen and the microscopic algae....
