11/15/11 Report - Erosion at One Beach & Odyssey Marine Reports
Written by the Treasureguide for the exclusive use of treasurebeachesreport.blogspot.com.
Photo of Erosion North of Jupiter Inlet.
This area is one of the better looking areas of the last couple of weeks. A lot of detectorists have been hitting this area, and there is word of a few cobs being found here.
Tom Guidus of Wreckovery Salvage sent this photo and reported a lot of modern trash.
You can see the sea weed which indicates that light materials were probably washing in just before the photo was taken.
See Tom's web site by going to this blog's link list.
Another Photo of Eroded Dunes in Area North of Jupiter Inlet.
You can see how the back dunes are eroded. That is the kind of thing that I like to see.
What you would want to determine is if the dunes there are composed of undisturbed naturally accumulated sand or not.
It is always helpful to know something of the history of any exposed layers of sand. Try to identify any layers, where they came from and when they were deposited. All of the information can be helpful.
Look at the composition of the sand, coarseness, color, and contents. When you find objects associated with a layer, remember what kind of things were found in it.
Some layers will be mixed. That often indicates that the layer has been disturbed. You might find modern plastic mixed in with fossils that are thousands of years old. That can be an indication of a disturbed layer, but sometimes it will be the result of newer top layers falling down the face of an eroded dune and mixing with older layers. Try to figure out just what is going on.
Note the rounded rock in the middle of the photo. That looks like it could be a ballast rock.
You'll occasionally find ballast rocks on a beach. That can be a good indicator.
Thanks for the report and photos Tom.
Odyssey Marine Explorations provides a nice list of research papers on underwater archaeology. Here is a link to those.
You might also enjoy reading their third quarter (2011) report. It talks about a lot of their projects and costs and revenues.
They didn't do as well this year compared to last. That, I guess, is one reason the price of their common stock has been decreasing lately.
Here is the link to that report.
The wind is out of the southeast now. That usually means that the beaches in most locations will be accumulating sand. It usually means also that there is a good chance of shell piles and other light materials being washed up.
Unfortunately southeast winds are usually not good for coin hunting.
I'm sticking with a beach conditions rating of 1 (poor) for now. I don't see any change coming for at least a few days.
