We also found some general latitudinal patterns in intertidal seagrass, with the proportion of the intertidal area covered by seagrass increasing as you go south, and not only that, the cover/density of that seagrass tends to increase the further south you go.

From this total area we found hotspots of intertidal seagrass across the whole of Europe, with three notable hotspots coming out as the biggest in the North Frisian Wadden Sea (Germany), Arcachon Bay (France) and Ria Formosa (Portugal).

Then using a cloud-computing approach we classified the over 15,100 km ² of intertidal area in Europe, finding an area larger than both Paris and Lisbon combined appeared to be seagrass at over 50 % cover (212 +/- 18.8 km ²)

By updating the ICE CREAMS model, we improved its accuracy from 82 % in previous work to 91 % by decreased its’ false positive rate on over 60,000 independent and openly accessible validation data.

5) lead a Call-to-Action for the availability of data following the FAIR principles to improve future iterations of this European scale map.

Through this work we feel we successfully achieved all of the first four aims and hope that this paper will achieve the fifth: a Call-to-Action!

2) use ICE CREAMS to create a contemporary map of Intertidal Seagrass for Europe

3) provide a robust and scalable methodology to allow others to map intertidal seagrass at large scales

4) provide an open-access and hopefully easy to use tool to view this map

We had 5 main aims:

1) improve and fine tune the open access model Intertidal Classification of Europe: Categorising Reflectance of Emerged Areas of Marine vegetation with Sentinel-2 (ICE CREAMS 🍨)

We aimed to do this by using products or data that were openly available and consistent across Europe from the Copernicus Sentinel-2 imagery, the Google Earth Engine cloud-computing used to sort this imagery, the ICE CREAMS model used to classify the imagery even down to the outputs themselves.

We have managed to create *An Intitial Map of European Intertidal Seagrass*. This is, to our knowledge, the first ever attempt to map Intertidal Seagrass at the scale of Europe (or any continental scale for that matter)!
