“…Depending on the need to obtain data from a particular type of marine environment, namely, deep sea/oceans, lakes, estuaries, inland rivers, and temporal resolution (time-frequency matching of the dynamics of measured parametric quantity), different observatory platforms were developed. These observatories can be surface buoy [11], Autonomous Underwater Vehicles (AUVs) [12,13], Remotely Operated Vehicles (ROVs) [14,15], or observatories in onboard ocean vessels [16]. There are examples of platforms for measuring and monitoring water quality parameters using open-source hardware and software [10,17,18].…”
