I use to use the My sound web site a lot to get up to the minute conditions, and I like the web cam they had so I could actually see the sea conditions. I checked it out yesterday, and they have improved the webcam which allows you to control where and what you want to see with zoom and other features. It's awesome, not sure how well it works when you have a lot of different people trying to control the camera.
It's a great tool for real time sea conditions in Groton, Enjoy!
Be sure to give it a minute to load
