Data from : A long-term dataset of topography and nearshore bathymetry at the macrotidal pocket beach of Porsmilin, France

The archived multi-sensor dataset detailed here presents the results of topographic and bathymetric surveys at Porsmilin, a macrotidal pocket (embayed) beach situated in Brittany, in northwest France.

The Porsmilin beach survey program was launched in January 2003 by the Institut Universitaire Européen de la Mer (IUEM/Univ. Brest) and is continuing today in the framework of the French coastal observation service SNO-DYNALIT.

The dataset contains over 16 years of beach profile surveys and a large collection of recurring high-resolution subtidal and subaerial digital elevation models (DEMs) obtained using various survey methods. T

he dataset is accompanied by time-series of inshore waves and water levels, and enriched metadata, that will facilitate its future reuse in coastal research.

The dataset is structured as follows, with separate metadata (child and grand child records) for :

  1. beach profiles ⮑ 2003/2019 ⮑ 2020 ⮑ 2021 ⮑ ...
  2. topographic DEMs ⮑ 2003/2019 ⮑ 2020 ⮑ 2021 ⮑ ...
