I received the DVD of Block aerial images from Sandman Calendars and was amazed at how much of Block is sand just beyond the boulder coast. This DVD has given me new ideas and locations to try in the future.

Sorry; I just saw this thread. Been very busy lately...
Rob Holman and his time lapse video is one of the neatest applications of fairly simple technology I've seen; he started in the 80's at Duck, N.C., where it is ongoing, and they have videos that compress all the years down into a few minutes.. it's very cool. You can see up to date images:

Also, the Crab is one of the more interesting pieces of equipment I've seen; they (Army Corps) also has some WWII era Lark's all instrumented up that travel from the beach to the offshore collecting data, giving them some of the most seamless data in the world. I have to settle for running our r/v just offshore of the beach and hope the sonar can see all the way to the shoreline
We don't really have significant offshore bars in RI, some limited ones in Misquamicut, but nothing like the outer cape or NC; we simply do not have enough sand!
As far as dynamics of the shoreline, the KEY point in New England, is that there is not a winter beach/summer beach profile. It is storm driven; years w/ no fall/winter storms and the 'winter' beach looks just like the 'summer' beach, but a couple of hurricanes in august and the 'summer' beach is awfully erosional... Then throw in an April Nor'Easter and it really complicates things...
