The 17 pages that link to Mean sea level, each with the reason it gives.

• Sea level riseNarrower topic: Sea level rise describes a change in this averaged reference quantity.

• Tidal rangeRelated: It provides a reference for placing tidal highs and lows in vertical context.

• GeoidCompared with: The geoid approximates a global mean-sea-level surface, while actual mean sea level varies in space and time.

• ElevationRelated: It is a common reference for reporting land elevations.

• Sea-level changeRelated: It provides a local baseline for tracking persistent rises and falls.

• Eustatic sea-level changeNarrower topic: Eustatic change concerns the global average rather than a single coastal gauge.

• Vertical datumRelated: Local mean sea level has historically supplied a practical zero for elevation datums.

• Tide gaugeRelated: Gauge records are commonly summarized as long-term changes in local mean sea level.

• Sea levelBroader topic: This averaging convention supplies many practical sea-level references.

• Great Trigonometrical SurveyRelated: Peak heights required a common vertical reference tied to sea level.

• Relative sea levelRelated: Relative sea-level records compare land elevation with a locally averaged sea surface.

• Aviation altitudeRelated: Altitude above mean sea level is the basis for most charted elevations and flight levels.

• Orthometric heightRelated: The geoid approximates global mean sea level, giving orthometric height its familiar elevation interpretation.

• Figure of the EarthRelated: It offers an intuitive approximation of the geoid, though tides and currents complicate the match.

• Earth ellipsoidRelated: It is a practical height reference, unlike the ellipsoid’s purely geometric surface.

• Height above mean sea levelRelated: It supplies the reference level named in this height measure.

• Ocean surface topographyRelated: It is a common baseline for describing sea-surface height, though it varies geographically.
