noaa_marine_find_stations ~1599 tokens
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 p
noaa_marine_get_conditions ~497 tokens
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
noaa_marine_get_current_profile ~353 tokens
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,
noaa_marine_get_currents ~1208 tokens
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 de
noaa_marine_get_monthly_means ~980 tokens
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 yea
noaa_marine_get_ocean_observations ~504 tokens
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
noaa_marine_get_tide_predictions ~1146 tokens
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 h
noaa_marine_get_water_level ~1398 tokens
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
