Coastal erosion thread

LD - probably did handle them briefly, within the context of lab work. And was also on site, but I won'd disclose which/where, respecting the clients. I'd assume it would be similar across many operations like this world-wide, and that some sands (as well as granite, for example) possess a slight radioactivity. The doing bit was my job - I loved that line of work, all the travel, new sites, new people, remote work.
And yes, you get to see things occasionally that make you go "Whoa!" Exposure to many substances will have safe "limits" usually imposed after much study, and I'm happy I was within those limits. Er, hopefully...
What I'd like to say is: "The radioactive sands... changed me and gave me super-powers. I can now look through clothing pieces. I now act tirelessly for the greater good, only choosing when to use my powers with great restraint." As Leslie Nielsen said: "With great power, comes..."
Great responsibility!
Absolutely!

And a bonus, pretty dangerous in coastal dune systems:

At a more localised level around Newcastle, a few of us have a theory that in addition to the sand dune stabilisation (e.g. Nobbys) and shore stabilisation along Merewether/Bar Beach stretch, the restricted stormwater outflow onto the beaches has also adversely impacted the sand banks and waves. For example back in the day there were pretty consistent left and rights directly off the drain outflows at Merewether, South Bar, Southey, and Newcastle. Just a theory, but appears to be more than coincidental. As a side note the the restricted freshwater outflow has also contributed to the lower level of oysters around the rocks these days (change in salinity for spawning).
There's not really a coastal erosion thread that I can see, beyond some excellent articles on the site. Post up examples you find in your area, and maybe how the sand banks and wave quality change.
