The Deep Chlorophyll Layer of Lake Ontario

The deep chlorophyll layer is an increase in chlorophyll concentration below the waters surface. Typically this maximum is related to the thermocline in its development in the spring and breakdown in the fall. The thermocline is a layer of water with a rapid temperature change by depth. From 2004 to 2006, sampling was conducted from mid May to early November. At least every 2 weeks the water column was examined with a Sea-Bird CTD off of the SUNY Brockport Madtom vessel at a depth of 100m. The data reflected that a deep chlorophyll layer was present in Lake Ontario at a depth of 10-20m. The layer typically developed in the beginning of June and dissipated in September.
