12/17/21 Report - A Look At Some Beaches Around the Treasure Coast. Tracing Metal Sources.


Written by the TreasureGuide for the exclusive use of the Treasure Beaches Report.


Ambersands Beach Thursday Morning.


Yesterdady I showed you a couple beaches from Hutchinson Island where there were some good long cuts at both John Brooks and Frederick Douglass beaches.  I mentioned that it appeared on the lowering morning tide that less dense objects, such as plastic and jellyfish, were washing up onto the slope. 

I noticed a few Portuguese Man O' War on the beach.  Those can give a nasty sting, especially if you get the tentacles of a big one wrapped around your leg, as I once did.  I suppose some people are more sensitive to them than others.

DJ sent some photos from beaches in the Vero and Sebastian area from Thursday morning.  It appears that there had been a little erosion there too, but I saw no sharp cuts in his photos.

All the beach photos I'm posting today are from DJ and were taken Thursday morning around 9 or 10 AM.

Ambersands Beach Thursday Morning.

The old cut you see at Ambersands has been there a while.  You can see that the previous high tide did not get back to the old cut.   You can also see some seaweed being deposited onto the beach front.


Golden Sands Beach.

At Golden Sands you can see that the previous high tide did not get back very far, and you can see some seaweed that was deposited as the tide went out.


Golden Sands Beach.

There is a little scalloping of the beach at Golden Sands.  I think you tend to get more scalloping of the beach when the primary and secondary swells are coming from different directions.   Yesterday you could see the breaking waves nearshore colliding from different directions.


Wabasso Beach Thursday Morning.


At Wabasso the water did not get back to the old cuts.


Wabasso Beach.

Again, you can see that the previous high tide did not get back very far.


Turtle Trail

The Turtle Trail beach is pretty narrow in some areas, but the water did not get back to the dunes in the areas shown in these photos either.


Turtle Trial 

Yesterday at John Brooks there were some people in the water and you could see it was only knee high a good way out.  There was a lot of sand in front of the beach down there.  That is something to notice.


Turtle Trail

In the above photo of Turtle Trail you can see a steeper slope back towards the dock.

Thanks to DJ for all of those photos.


If you combine these recent looks with what has been happening with the tides and surf since, you'll have a pretty good idea of what things look like today.

For the first time, a scientific team led by Flinders University archaeologists, working with the Institute of History (CSIC) in Spain, has examined the origins of Iron Age metal items from an archaeological site in southwest France and found they were sourced from a variety of Mediterranean locations...

The underwater site of Rochelongue, believed to be four small boats located west of Cap d'Agde in southwestern France and discovered in 1964, dates to about 600 BCE and its cargo included 800kg of copper ingots and about 1,700 bronze artefacts. They contain very pure copper with traces of lead, antimony, nickel and silver.

Flinders University maritime archaeology researcher Dr Enrique Aragón Nunez says the isotope analysis shows the composition of different ingots in the cache is consistent with Iberian and also eastern Alpine metalliferous sources, and possibly some Mediterranean sources – illustrating that water trade and movement was active in this period between Atlantic, Continental and Mediterranean circuits...

The new surf predictions are disappointing.  They looked better a couple days ago.
