There is a slight problem with colour conversions in UK south, so you could check with a site such as getmap as to whether this was the real colour. But of course, that's not the issue here. Clearly you have found the secret location of the annual leech drowning contest. As is well known, England being wet suffers from leech plagues, and in order to control numbers, they have this annual drowning event where people from all parts of the world meet to go on leech rampages, as a substitute for the ideological incorrect fox hunting of yesteryear. Hunters, covered to the gills in leeches, wade out into the deeper water and with cries of "LeechyGo" dive under. But I'm sure you know all this.

Red seaweed ?Chris Low.

If it was Sydney, I'd probably mutter the word 'outfall'...In reality, it's probably a 'peat plume'.When the ocean encroaches on the land (i.e. a beach...) and there is a buried peat bog under it, the bog becomes open to the sea - and brown water results. We have one near my home in Sydney, at a place called Long Reef. The beach on the Northern side has a peat bog under it and the beach is called 'Brownwater Beach', although if you didn't live there, you'd never know why - the water only turns brown during calm periods just after a storm. Most of the time it's very pretty. Only if you go to a high place (Long Reef or Collaroy Plateau - or an aircraft...) can you see the 'murk' oozing from under the sand.Just an idea...At least if it was an outfall, you wouldn't be able to smell it :-roll
