Meet Our MAPRs

Thanks to the generosity of Ed Baker and Sharon Walker at NOAA/ Pacific Marine Environmental Laboratory we have six Miniature Autonomous Plume Recorders (MAPRs). These cute devices record temperature, pressure, optical backscatter and oxidation-reduction potential, all together those measurements help identify the signal of an active hydrothermal vent. We have one MAPR attached to JASON, one on Medea and the remaining four attached to the cable at a 40m spacing.
