these pics are of pools of water near the beach in an area called El Golfo on Lanzarote, Spain. Lanzarote is a desert island with active volcanoes and these pools are above vents from the volcano. The warmth of the vents causes algae to grow in them which makes the water appear to be green. The rocks in the pools contain a mineral called Olivine which is green in color and adds to the hue.
