DATA & FILE OVERVIEW

1. File List: 

all-carbohydrates.xlsx and all-carbohydrates-readme.txt – Seasonal carbohydrate content in leaves or rhizomes of a selection of species.

C-N-seasonal.xlsx   and C-N-seasonal-readme.txt – Seasonal C & N content from macrophyte species.

coastclim-dataset-10-21.xlsx and coastclim-dataset-10-21-readme.txt – Macrophyte data from the sampling October 2021.

coastclim-dataset-3-22.xlsx and coastclim-dataset-3-22-readme.txt – Macrophyte data from the sampling March 2022.

2. Relationship between files, if important: 

Macrophyte data and CN content can be linked on the site-quadrat level, whereas the carbohydrate can only be linked on the seasonal level.
