EGIM prototype, EMSO Generic Instrument Module

Developed within the frame of the European Union funded H2020 project EMSOdev, the EGIM is designed to consistently and continuously measure parameters of interest for the science areas outlined by EMSO, the European Multidisciplinary Seafloor and water column Observatory established as a European Research Infrastructure Consortium.

The EGIM is able to operate on any EMSO node, mooring line, sea bed station, cabled or non-cabled and surface buoy. A central function of EGIM within the EMSO infrastructure is to have a number of ocean locations where the same set of core variables are measured homogeneously: using the same hardware, same sensor references, same qualification methods, same calibration methods, same data format and access, same maintenance procedures.

An initial set of parameters selected for the prototype EGIM, primarily focuses on sensors monitoring; temperature, conductivity, pressure, dissolved O2, turbidity, acoustics and ocean currents.

Key Features
  • Provides 7 generic parameters and can host up to 16 sensors
  • Compatible with mooring, cabled and non-cabled marine platforms
  • Ultra-low power and high bandwidth capacity
  • Time stamping suitable for seismology and acoustic sensor synchronization
