"Can you find a one-stop source for sea-level information, with interactive tools for linear and quadratic regression analysis, and graphing, of measured sea-level trends?"

Assistant: Yes — there is a one-stop source that matches exactly what you asked for: edit

Yes — there is a one-stop source that matches exactly what you asked for:

SeaLevel.info edit

URL: https://www.sealevel.info/ SeaLevel Info[2]

Key features:

  • Consolidates sea-level measurements (tide gauges) from major data repositories like NOAA and PSMSL. SeaLevel Info[3]
  • Includes interactive graphing of measured sea-level data. SeaLevel Info[4]
  • 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[5]
  • Regression displays include confidence intervals and prediction intervals. SeaLevel Info[6]
  • You can adjust date ranges used in regression and graph display. SeaLevel Info[7]
  • Supports visualization options like smoothing and overlaying atmospheric CO₂ data for comparative context. SeaLevel Info[8]
  • Covers over 1,200 locations worldwide. SeaLevel Info[9]

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) edit

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[10]
  • PSMSL (Permanent Service for Mean Sea Level) – global tide gauge database with downloadable records. PSMSL[11]
  • NASA Sea Level Change Portal tools – interactive visualization and data tools (not necessarily regression focus). NASA Sea Level Change Portal[12]

If you want step-by-step instructions on using SeaLevel.info for regression analysis or scripting downloads of its data for further analysis in R/Python, let me know and I can provide a guide.
