Return tide-gauge water-level observations at a CO-OPS station. Default datum is MLLW (Mean Lower-Low Water, the US navigational default) and units metric (meters). Requests without begin_date/end_date default to today's 6-minute observations. Requests with an explicit range are capped at 31 days for 6-minute data and 365 days for hourly (interval=h). q quality flag: p preliminary (last 30-45 days), v verified (older, passed CO-OPS QC). Attribution: NOAA CO-OPS Tides and Currents (api.tidesandcurrents.noaa.gov).
