Instrument Description
Chemical Miniaturized Analyzer
The In-Situ CHEmical MINIaturized (CHEMINI) sensor is a mono-parameter in situ chemical analyzer based on flow injection analysis and colorimetric detection to perform the analysis of dissolved iron and total sulphide in the seawater.
CHEMINI is one of the sensors on Tempo-Mini, installed at Endeavour Ridge, and used to measure iron (Fe) properties near hydrothermal vents.
The study of chemical parameters at hydrothermal vents is important. As hot effluent encounters the cold seawater (~2 degrees C), minerals precipitate from the element-rich vent water. Black smoker vents are found in areas where the effluent is very hot (~350 C). These types of vents precipitate iron sulphides, giving rising plumes a dark colour and cause the formation of sulphide-mineral deposits on the seafloor.
