Hi Folks,

Have you ever looked at a body of water and wished that you could see exactly what the bottom would look like if all of the water were drained out? Without all of the flopping fish, of course! Side-scan sonar is a technology that can allow you to do exactly that. By sending sound waves out to the side of the boat and turning the returning signals into a 3-D map we can easily see exactly what the bottom looks like and readily identify objects on the bottom. With the right resolution you can easily see an object as small as a car battery. Add in an integrated GPS system and the position of each item is marked right on your electronic chart so that you can easily find it again in the future.

So this is where the story starts to get interesting. Northeast Dive News, in association with Island Diving and local diver Peter Canning will be conducting a complete side-scan survey of Lake Ronkonkoma's 231 acres as a service to the local community. We will be working with the Suffolk County Legislature's Lake Ronkonkoma Advisory Board, headed up by Legislator John Kennedy, the NYS DEC's Freshwater Fisheries Unit, headed up by Regional Fisheries Manager Chart Guthrie, Islip Town Supervisor Tom Croci and Islip Parks Commissioner Joseph Montuori.

So what do we hope to accomplish? Lake Ronkonkoma has a long history as a recreational area, and we are certain that over the years quite a few different "objects" have found their way to the bottom. Once our survey is complete we will study the resulting images and dive on selected targets to make sure that there is no possibility of any of them presenting an environmental hazard, either at the present time or at some point in the future. Any targets that pose a risk to the health of the Eco-system will be removed, and all remaining targets will be added to the NYS DEC's database for inclusion in its Lake Ronkonkoma Artificial Reefing Project.

Want to get involved? As soon as the survey is complete we will begin dive operations, and we will have a small number of spots available for qualified local divers. Simply reply to this email if you would like to be considered for a volunteer position, or if you have any questions regarding the project.
