Gathering sea salt.
These were made near Shannah (Ferry port for Masirah) actually just a sleepy little place with a few buildings serving the ferry: although it has grown in size over the last year or so & soon may even have a coffee shop & what purports to be a hotel !
The pink tinge seen is from Halobacteria they are a rather interesting form of Archaea so are not actually bacteria and very dependant on salt, freshwater would kill them instantly. Confusing ! hence the links which give a better description than I ever could. Because even belonging to the Archaea family, they don’t follow the rules and are a branch with behavioural characteristics all of their own.
Ho and the reason I got these images is because I made a quick road trip to Masirah (work) so was lucky enough to catch this salt flat at its best. I have only once seen the whole area pink, in all the years I have made the trip (no camera – typical) but at least I got the salt this time.
