OriginalLion's manes and a moon jellyfish disturbing the pycnocline in the top water layer of Gullmarn fjord, Sweden. Photo taken on a sunny morning after rain, so it's likely that the top layer is warmer water with some freshwater added, making a thermocline coincide with a halocline and resulting in a very thin but visible pycnocline. This difference in density and the altered refractive index is what makes the water look "oily". The top of the largest jellyfish is breaching the surface, while its tentacles are stirring up the thin pycnocline layer.
