This is a great picture. It shows what appears to be water, or possibly ice. But the furrows in the sand under the water suggest the water is in liquid state, when the photo was taken.
The rocks and shoreline is evident and the depth of the water or liquid is visible.
But again, why no life if this is water? The water is not the anomaly here. There being no life evident is the anomaly. Study it yourself and tell me what you make out of it. https://canberrabuildinginspectionsact.com.au/product/unit-3-26-dominion-circuit-forrest-act/
