Upwelling
The major upwellings in the ocean are associated with the divergence of currents that bring deeper, colder, nutrient rich waters to the surface. There are at least five types of upwelling: coastal upwelling, large-scale wind-driven upwelling in the ocean interior, upwelling associated with eddies, topographically-associated upwelling, and broad-diffusive upwelling in the ocean interior.
Eddy Creek (Lackawanna River tributary)
Eddy Creek used to have flow, but has turned into a "leaky slow trickle" that carries acid mine drainage. In 2014, Joseph D'Onofrio, a senior engineering technician for GTS Technologies, compared the creek to an "old perforated pipe". Eddy Creek is an ephemeral stream.
