Joint Commission on Oceanography and Marine Meteorology (JCOMM) coordinates in-situ ocean observing networks from Data Buoy Cooperation Panel (DBCP, surface drifters, tropical moorings, OceanSITES), Ship Observations Team (SOT) (volunteer ship observations, ships of opportunity and underway surface measurements), Global Sea Level Observing System (GLOSS, tide gauges); and cooperates with Argo (profiling floats), International Ocean Carbon Coordination Project (IOCCP, ocean carbon observations), and Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP, repeated hydrographic sections). Many of these data are contributed through real-time ocean data systems (those reporting in time frames of hours to days).
In addition, there are other collectors of in-situ data, such as researchers executing their own programmes, commercial operators of ships, etc. who contribute other kinds of data than those represented above (such as Acoustic Doppler Current Profiler (ADCP)). Some are contributed in real-time and others in delayed mode. These data may appear in the data systems coordinated by IODE, a programme of IOC which is a co-sponsor of JCOMM.
