From: Turbulence-induced bubble nucleation in hydrothermal fluids beneath Yellowstone Lake

a Yellowstone Lake (USA). The northern part of the lake lies inside the 640 ka Yellowstone Caldera (dashed line). b Bathymetry of the Deep Hole thermal area (black rectangle in left panel). White triangles indicate active venting locations observed during remotely operated vehicle dives, and the black star corresponds to the hydrophone location. The spatial extent of the main discharge zone is shown with a red ellipse.
