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.

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.
Transverse Mercator · Ghana National Grid · metres · ×41 vertical exaggeration
Waterlines: May 2018 (broken) · Oct 2024 (full)
Band between traces: ground lost to the sea

DATUM −14 m INSTRUMENT RACK
6 datasets, powered and logging
Each channel below is a published dataset. Amber means the channel holds data; a dark lamp means the survey is planned but nothing is published yet.

— awaiting data
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.
