Bight of Benin Coastal Monitoring Programme

Waves, shorelines, and seafloor along Ghana's eastern coast — measured through the night by echo-sounders, wave buoys, and tide gauges. Scroll to descend through the record.

1,415 wave records · May 2023 – Aug 2023
11,388 shoreline points · 2018–2024
5,110 beach-profile measurements

DATUM −6 m SURVEY TRANSECT

Sixteen stations, Volta estuary to the Togo border

The programme surveys a single west-to-east line along the Keta coast. Every dataset below hangs off these stations.

DATUM −8 m WATERLINE PLATE

Two waterlines, six years apart

The frontage at echogram scale: the latest surveyed waterline burning sonar cyan, the first trace behind it as a ghost, and the band between them is the net change measured between the two campaigns.

NO RETURNS YET.
No bathymetry has been published. The sounder is on the rack and the screen stays empty until the first verified survey lands — we would rather show you nothing than something smoothed.

DATUM −28 m SPECIMEN · WAVES CHANNEL

Significant wave height, daily mean

One deployment, no smoothing. The band is the daily minimum-to-maximum envelope; the line is the daily mean of raw records.

Hs — daily mean & min–max envelope (m)

DEPLOYMENT MAY 2023 – AUG 2023 · N = 1,415

The full specimen — unsmoothed daily means, deployment gaps shown as gaps, and the underlying records — is kept on the Waves channel.
