This folder contains Figure SI1, as used in the Article’s Supplementary Information section. It is an overview of the study areas mentioned in the Article, as well as a more detailed view on Ketenisse mudflat (algal cover, elevation and sample locations on this mudflat).

Subfigure (a), i.e. overview of study area, was adapted from Google Earth Pro ((c) 2016 Google Inc.).

The aerial images of Ketenisse in subfigures (b) and (c) were taken by the “Agentschap voor Geografische Informatie Vlaanderen” (www.agiv.be). The photo is a small selection from the photos “Orthofoto’s, middenschalig, kleur 2012, Vlaanderen”. This specific section was photographed on 23 July 2012. Please find elaborate source info in the subfolder “SourceInfo”.

The digital elevation model in subfigure (b) was derived from laser scan measurements on Ketenisse (13 December 2016), as described in the Manuscript. Data is only shown in the elevation range 1.4m to 3.0m above NAP. 

In subfigure (c), the white dot indicates the central location of the cores taken for INSTRON measurements (Figure 7 in the manuscript). Red and blue dots indicate positions of the north-eastern resp. south-eastern cores of which X-radiographs were made (Figure 6). The white rectangle indicates the 44x49.5m focus area.

This composite image was made with help of Annette Wielemaker (NIOZ Yerseke) using ArcGIS.
