Returns a unified station list with source, data capabilities, coordinates, and — for NDBC — the physical platform class. This is the required first step to resolve place names or coordinates to station IDs before calling data tools. CO-OPS station IDs are numeric (e.g. 9447130 for Seattle); current station IDs are alphanumeric (e.g. ACT4176). NDBC buoy IDs are 5-character alphanumeric codes (e.g. 46041). Two axes are reported separately: `capabilities`/`type` describe the data products a station serves (tide, current, water_level, met, current_profile), while `platform` is the NDBC physical classification (buoy, fixed, oilrig, dart, tao, usv, other). CO-OPS stations carry no platform class. Provide latitude and longitude together for proximity search, or query/state for name-based search — both may be combined. Note: CO-OPS current stations are cataloged by monitoring capability, not prediction availability. If noaa_marine_get_currents returns no_predictions for a station, try the next nearest current station.

Live marine conditions from an NDBC buoy: wave height/period/direction, wind speed/gust/direction, sea-surface temperature, air temperature, barometric pressure, and dew point. All… Live marine conditions from an NDBC buoy: wave height/period/direction, wind speed/gust/direction, sea-surface temperature, air temperature, barometric pressure, and dew point. All values are SI units — wind in m/s, wave height in m, pressure in hPa, temperatures in °C. Exceptions: TIDE is in feet and VIS is in nautical miles (rarely populated at offshore buoys). Numeric fields are null when the buoy sensor did not report a value — this is normal for offshore buoys. Observations are updated approximately every 10 minutes; data may be 10–20 minutes old. Use noaa_marine_find_stations with source="ndbc" and types=["met"] to find station IDs near a location — met-flagged stations are the ones most likely to serve live conditions. Roughly a third of active NDBC stations report neither meteorological nor current data, and most of those have no observation file, so omitting the types filter will surface station IDs this tool cannot read.

Returns depth in meters, direction in degrees true (the direction the current flows toward), and speed in cm/s. Distinct from noaa_marine_get_currents, which returns CO-OPS tidal-current predictions (forecast max flood/ebb/slack) rather than these observed acoustic-Doppler measurements. A depth bin is reported whenever NDBC gives it a depth; its direction or speed is null when the sensor did not report that component. Use noaa_marine_find_stations with source="ndbc" and types=["current_profile"] to find station IDs — most NDBC stations serve no ADCP profile, so an unfiltered search returns IDs this tool cannot read.

These are forecast tidal-current predictions from CO-OPS — distinct from noaa_marine_get_current_profile, which returns NDBC observed ocean-current measurements binned by depth. Defaults to MAX_SLACK interval — the practical planning view showing when currents peak and when slack water occurs. Optionally returns 6-minute continuous predictions for detailed analysis. Current station IDs use alphanumeric format (e.g. ACT4176), distinct from numeric tide/water-level IDs. Date range is limited to 1 year per request. Use noaa_marine_find_stations with types=["current"] to obtain valid current station IDs.

This is the water-column counterpart to noaa_marine_get_conditions, which returns surface meteorological and wave data (wind, waves, sea-surface temperature) — use this tool for what the water is doing below the surface, that one for weather and sea state at the buoy. Returns the most recent observation as one reading per reported depth; most stations report a single depth, but some report several at the same time. Sensor coverage is sparse — most stations populate only water temperature and salinity — and any value the station did not report comes back null rather than a fabricated zero. Latitude and longitude are null when the station is absent from the NDBC active-stations list. Sub-surface sensors are on only a subset of NDBC stations and are not marked by any station-catalog flag, so no capability filter guarantees coverage: call this on candidate NDBC station IDs from noaa_marine_find_stations with source="ndbc", and expect the observations_not_found error on the many stations that serve no .ocean file.

Returns time, height, and tide type (H=high, L=low) for each event when using the default hilo interval, or 6-minute interval predictions for a detailed tide curve. Datum defaults to MLLW (mean lower low water — standard for US nautical charts). Date range is limited to 1 year per request; split longer ranges across multiple calls. Use noaa_marine_find_stations first to resolve a station name or location to a numeric station ID.
