In some light this water appears almost yellow when very shallow, orange to red and then black at depths. The stain in the water is tannin from the root systems of the freshwater swamp plants upstream. Here it flows over the pure white silica sand of the surf beach before flowing into the sea.
Golden star for golden water as well - I found some green tides in the Netherlands a couple of years ago and have to look for.. I'll keep you posted. As far as I've been told, this sparcling green on the waters surface is dued to some tiny algaes or seaweed! By stepping on the wet ground your feet produces auras around and it glows for some seconds. Funny and I'll try my very best to catch them again - the difficult is to have a mostly dark full moon night..
Thanks for the G*, Oliver!! I look forward to seeing your algal bloom images. In warm climates, we see quite a bit of algal bloom on waterways, where they a re nutrient enriched especially because of runoff from farming areas. But I would love to see what you can do with your night images, so I hope they are successful.
I made a series of bioluminescentic plants before, but only as a gif-installation for an technical paper during study.. Oliver
Wonderful, unusual colours for water! Lovely photo, Ian! My best wishes, May
This ecosystem that produces tannin coloured water in the freshwater lakes and swamps behind the dunes is the same as that on Fraser Island. One of my images that was your choice for your desktop a year or so ago is the same phenomenon. That one was taken of water in a lake, this one of water that is running out of a swamp then across the surf beach into the ocean.
If you keep photographing the details and patterns of the winter ice and snow in the Emmental, I'll keep imaging the details of our beach systems for you.
Warmest regards from Brisbane,
This conversation has an interesting thread. I have come across this amazing phenomenon of "sparkling water" in Tenby in south Wales. We called it phosphorescence, the emission of light by bioluminescent plankton,. It was spectacular to swim when it was dark, as the sea lit up every time a splash was made :))
Thank you Ian and Oliver for reminding me of this :))
I'll try my very best until Sunday!
I'll be in the Netherlands again..
Dear Amelia and Oliver,
When I am in the sea or ocean baoting at night in the tropical waters of the Pacific, in PNG or Tonga, it is normal to sit in the boat trailing one's fingers in the water to create the illumination by the plankton! It simply exceeds my capacity to understand the process. I am amazed or even in awe and that would not be too strong a description.
I hope we get to see your images, Oliver.
It's just one of the magical mysteries of Nature Ian. I understand little of it all, but that doesn't lessen my appreciation. She is there to be observed with awe, studied and explained. But it's great to be just an observer :)
Dear Ian, unbelievable color for the ocean.
I became very happy that you like my Switzerland photos. Warmest greetings. Fü.
This is actually fresh water, as it overflows from a shallow lake and runs across the beach to the ocean.
It is like an overflowing cup of tea. And my cup overflows with joy when I am there in this beautiful environment. Just like we all do when we visit Switzerland.
