Apparatus for skimming surface fluid off of a main fluid including a floating collection housing adapted to float in such main fluid and a rotating skimming wheel having an annular skimming chamber including a plurality of compartments, each compartment being opened by a gravity actuated valve for skimming surface fluid off of the main fluid when such compartment is rotated into the main fluid so that the surface fluid is skimmed from the main fluid into such compartment, the compartment being subsequently emptied into the floating collection housing after rotation out of the main fluid. The buoyancy of the apparatus is adjustable to control the position of the compartments during skimming operations with respect to the interface between the surface and main fluids.
