• noaa_marine_find_stationsFind Marine Stationsread-only

  Find CO-OPS tide, water-level and current stations and NDBC buoys near a location, by name, or by station ID, returning a unified list with source, data capabilities, coordinates, and — for NDBC — the physical platform class. This is the required first step for resolving a place name, a coordinate pair, or a bare station number to the station IDs the data tools take: CO-OPS tide and water-level IDs are numeric (e.g. 9447130 for Seattle), CO-OPS current IDs are alphanumeric (e.g. ACT4176), and NDBC buoy IDs are 5-character alphanumeric codes (e.g. 46041). Two axes are reported separately — capa…

• noaa_marine_get_conditionsGet Marine Conditionsread-only

  Live marine conditions from an NDBC buoy: wave height, period and direction, wind speed, gust and 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 — except TIDE, which is in feet, and VIS, in nautical miles, both rarely populated at offshore buoys; a numeric field is null when the buoy sensor did not report a value, which is normal offshore. Row cadence varies by station from 5 to 60 minutes, so observed_at can be that old, and NDBC writes each block of columns o…

• noaa_marine_get_current_profileGet Ocean Current Profileread-only

  Observed ocean-current depth profile from an NDBC ADCP buoy — the most recent measurement of current speed and direction at each depth bin, returning depth in meters, direction in degrees true (the direction the current flows toward), and speed in cm/s. It is distinct from noaa_marine_get_currents, which returns CO-OPS tidal-current predictions of max flood, ebb and slack rather than these observed acoustic-Doppler measurements. A depth bin is reported whenever NDBC gives it a depth, and its direction or speed is null when the sensor did not report that component. Use noaa_marine_find_stations…

• noaa_marine_get_currentsGet Tidal Currentsread-only

  Tidal current predictions for a CO-OPS current station: max flood and ebb speeds, slack times, and the station's mean flood and ebb bearings. These are forecast predictions from CO-OPS, distinct from noaa_marine_get_current_profile, which returns NDBC observed ocean-current measurements binned by depth. The default MAX_SLACK interval is the practical planning view, showing when currents peak and when slack water occurs, and a 6-minute interval returns the continuous curve for detailed analysis, each row carrying its own flood/ebb/slack sense. A station can publish predictions for several depth…

• noaa_marine_get_monthly_meansGet Monthly Meansread-only

  Verified monthly means for a CO-OPS water-level station, one row per station-month: the month's highest and lowest water, its tidal datums (MHHW, MHW, MSL, MTL, MLW, MLLW, DTL), tidal ranges (GT, MN, DHQ, DLQ), and lunitidal intervals (HWI, LWI) — the record a sea-level or tidal-range trend over years to decades is read from. Heights are relative to the requested datum in the requested units. A value CO-OPS publishes no figure for is omitted rather than reported as zero; a Great Lakes station carries only highest, msl, and lowest. A range may span up to 73,000 days, checked before the call, an…

• noaa_marine_get_ocean_observationsGet Ocean Observationsread-only

  Live sub-surface oceanographic observations from an NDBC station's water-quality sensors: at each reported depth, water temperature, conductivity, salinity, dissolved oxygen as both saturation percent and concentration in ppm, chlorophyll, turbidity, pH, and redox potential. This is the water-column counterpart to noaa_marine_get_conditions, which returns surface meteorological and wave data — use this tool for what the water is doing below the surface, that one for weather and sea state at the buoy. It returns the most recent observation as one reading per reported depth, and most stations re…

• noaa_marine_get_tide_predictionsGet Tide Predictionsread-only

  High and low tide predictions for a CO-OPS tide station over a date range. The default hilo interval returns the time, height, and tide type (H for high, L for low) of each event, while the 6-minute interval returns the detailed tide curve. Most tide stations are subordinate — CO-OPS derives their high and low events as offsets from a reference station and publishes no 6-minute curve for them — so interval="6min" reaches only a reference station, and a subordinate station comes back as subordinate_no_6min naming the reference station to ask instead; the prediction_class on a noaa_marine_find_s…

• noaa_marine_get_water_levelGet Water Levelread-only

  Observed water level, real-time or historical, for a CO-OPS water-level station, paired with tide predictions for the same period so the residual (observed − predicted) shows storm surge when positive and anomalous drawdown when negative. The interval selects the cadence: 6min (default) is the full curve, hourly and high_low cover months to a year of the same series at far fewer rows, and daily_mean serves Great Lakes stations only. Each interval carries its own CO-OPS range ceiling — 31 days for 6min, 365 for hourly and high_low, 3655 for daily_mean — rejected locally before the call, and onl…
