Hello from Phoenix
This is a new one on me. Naturally, my thinking goes to the folks at
Dyno-Gel and other weather modification companies.
Maybe it is only “grey sludge” and innocuous.
Best to all,

Beach sludge on Waiheke

12.01.06 6.00am

A grey sludge reported on a Waiheke Island beach is likely to be an
accumulation of marine life that has been washed ashore, the Auckland
Regional Council said yesterday.

ARC pollution response team leader Rowan Carter said the National
Institute of Water and Atmospheric Research had suggested the cause of
the Onetangi Beach sludge could be a marine invertebrate called a
salp.

“It will be uncomfortable to touch, but … it’s innocuous,” he said.
