How many vent fields? New estimates of vent field populations on ocean ridges from precise mapping of hydrothermal discharge locations

•Standard surveys find mean vent spacings of 12–220 km on fast (>55 mm/yr) ridges.•Tows covering 1470 km with optical and chemical sensors find spacings of 3–20 km.•One-fourth of identified sites are isolated, apparently low-temperature discharge.•Closer spacings constrain models of faunal disper...
