Marine Information Service (MARIS) in The Netherlands

National databases of coastal and marine information in the Netherlands are operated by Marine Information Service (MARIS) and Royal Netherlands Institute for Sea Research (Royal NIOZ)^[1]. An overview of databases for point data is given in Table 1.
