Marine technology. Ocean observation systems. Design criteria of ocean hydro-meteorological observation systems reuse and interactionWhat is ISO 21851 about? ISO 21851 specifies the overall framework of ocean hydro meteorological observation systems, including the system function composition, the data structure type and data transmission format and protocol, as well as the input and output interface. These systems support automatic measurement of e. g. buoy, submersible, and shore station instruments, with output interfaces, and provide observations on e. g. water temperature,
