June 19 Eco-Cruise with Cornell's AUV!
We had a packed boat for this past Sunday's cruise- thanks to everyone who helped make the first mini-sub luanch of the 2011 season a success! The student-designed Automated Underwater Vehicle, "Drekar", navigated two transects in the lake, generating video plant surveys and basic water quality data. (Video links on the way!) This was the team's first test outside of Teagle Pool at Cornell, and they did great.
In support of the mini-sub based surveys, we also conducted Secchi clarity and plankton tests. After a fairly extreme spring season, we are seeing clarity measurements returning to a "typical" range for the south end of Cayuga Lake, with 2.5 meters of clarity on the east side, near E. Shore marina, and 4 meter clarity along the west shore. This increasing clarity corresponds to a decline in phyto-plankton concentrations that have recently been blooming (see earlier trip reports). Thanks to everyone who participated!
