Sea levels, readable by anyone.

A launch site that turns dense sea-level datasets into one clear story, with an interactive chart at its centre.

The question

Tidewell turns public sea-level data into local projections. The data is good. The way people met it, as spreadsheets and PDFs, was not.

The idea

Build the site around the one question every visitor arrives with: what happens to my coast, and when?

The system

A restrained identity with one accent for projections, and a chart treatment that separates measured data from modelled futures at a glance.

The motion

The chart draws itself from the past to today, then switches to a dashed line for the projection, so the difference is felt before it’s read.
