Chemical investigations of groundwater and submarine hydrothermal fluid exhalations at Panarea, Italy

摘要

Abstract In 2015 samples of hydrothermal fluids of the submarine hydrothermal system Panarea at nine different investigation areas including the groundwater of the island Panarea were taken. The on-site parameters categorize the found hydrothermal fluids as acidic (pH <2.4-5.5), reducing (EH : around -50 mV) and highly mineralized (up to 120 mS/cm). The investigation areas Black Point, Fumarolic Field, Hot Lake and La Calcara are singled out, showing the most distinguished characteristics, where.
