Key features:
* Consolidates sea-level measurements (tide gauges) from major data repositories like NOAA and PSMSL. SeaLevel Info<ref>{{cite web|title=SeaLevel Info|url=https://www.sealevel.info/about.html|publisher=SeaLevel Info|access-date=2025-12-28}}</ref>
* Includes interactive graphing of measured sea-level data. SeaLevel Info<ref>{{cite web|title=SeaLevel Info|url=https://www.sealevel.info/|publisher=SeaLevel Info|access-date=2025-12-28}}</ref>
* Offers linear and quadratic regression analysis on the data — you can fit a line or curve to the record and see the calculated trend and acceleration. SeaLevel Info<ref>{{cite web|title=SeaLevel Info|url=https://www.sealevel.info/about.html|publisher=SeaLevel Info|access-date=2025-12-28}}</ref>
* Regression displays include confidence intervals and prediction intervals. SeaLevel Info<ref>{{cite web|title=SeaLevel Info|url=https://www.sealevel.info/about.html|publisher=SeaLevel Info|access-date=2025-12-28}}</ref>
* You can adjust date ranges used in regression and graph display. SeaLevel Info<ref>{{cite web|title=SeaLevel Info|url=https://www.sealevel.info/about.html|publisher=SeaLevel Info|access-date=2025-12-28}}</ref>
* Supports visualization options like smoothing and overlaying atmospheric CO₂ data for comparative context. SeaLevel Info<ref>{{cite web|title=SeaLevel Info|url=https://www.sealevel.info/about.html|publisher=SeaLevel Info|access-date=2025-12-28}}</ref>
* Covers over 1,200 locations worldwide. SeaLevel Info<ref>{{cite web|title=SeaLevel Info|url=https://www.sealevel.info/|publisher=SeaLevel Info|access-date=2025-12-28}}</ref>

This site specifically matches your request for a single platform where you can select tide gauge locations, graph the data, and perform built-in regression analysis interactively.

===== Other resources for sea-level data (less directly matching regression tools) =====

These are authoritative data sources you can combine with external analysis if needed:
* NOAA tide gauge trends & data – official long-term sea level trend charts and downloadable data. NOAA Tides and Currents<ref>{{cite web|title=NOAA Tides and Currents|url=https://tidesandcurrents.noaa.gov/sltrends/regional_index.html|publisher=NOAA Tides and Currents|access-date=2025-12-28}}</ref>
* PSMSL (Permanent Service for Mean Sea Level) – global tide gauge database with downloadable records. PSMSL<ref>{{cite web|title=PSMSL|url=https://psmsl.org/|publisher=psmsl.org|access-date=2025-12-28}}</ref>
* NASA Sea Level Change Portal tools – interactive visualization and data tools (not necessarily regression focus).
