Where does vent collide?

In ocean science a hydrothermal vent is a seafloor opening where geothermally heated, mineral-rich water discharges, most often along mid-ocean ridges, and the term also names the dense chemosynthesis-based ecosystem that these fluids sustain in the absence of sunlight. Corliss and colleagues' 1979 report of warm springs on the Galápagos Rift revealed thriving communities powered by chemical rather than solar energy, redefining the vent as a biological as well as a geological object. The referent is a seafloor discharge site and its ecosystem, a different construct from the mouth of an erupting volcano or the psychology of releasing anger.[1]

In psychology, venting refers to expressing pent-up anger or frustration outward, the folk idea, rooted in catharsis theory, that discharging emotion relieves pressure like opening a valve. Bushman's 2002 experiments tested this directly and found that venting anger, far from extinguishing it, tended to keep arousal high and increase later aggression, undercutting the hydraulic metaphor the word carries. The referent is a behavioural-emotional process studied by its downstream effects on affect and aggression, unrelated to a volcanic opening or a seafloor spring except through the shared image of release.[2]
