Evaporation fog

It is cold this morning. Looks like the estuary is boiling, looked it up on a weather site, known as evaporation or steam fog. Steam fog forms when cold air moves over warm water. When the cool air mixes with the warm moist air over the water, the moist air cools until its humidity reaches 100% and fog forms. This type of fog takes on the appearance of wisps of smoke rising off the surface of the water.
