Oceans, seas, and coastal waters — their physical properties, circulation, and dynamics. This twig covers the marine water mass itself, including its temperature structure, salinity, currents, and tides.
Scope
- Sea surface: Temperature (as a water mass property), salinity, wave height, current direction
- Water column: Temperature profiles, salinity stratification, mixed layer depth
- Tides and waves: Tidal gauges, wave buoy data, tidal models
- Currents: Surface and deep ocean circulation, coastal currents
- Bathymetry: Water depth (shared with Topography for seafloor geometry)
- Sea regions: Named sea areas, maritime zones, EEZ boundaries
