The folder `stordalen-malhotra-2024-1` contains a `.png` file with the description of the transects and a spreadsheet `.xlsx` including three data sheets:
1. `metadata` Meta data information
2. `Malhotra and Roulet decomp` Data table with the columns described below
3. `Well locations` GPS coordinates in SWEREF99 TM ([EPSG code 3006](https://epsg.io/3006)) of each litter bag triplicate location
##### Data table column description
| Column name | Unit | Description |
|--------------------- | ----- | ----------------- |
| Transect | | Transect name at Stordalen (see locations tab if needing specific locations) |
| Well | | Well name at Stordalen (see locations tab if needing specific locations) |
| type | | Habitat type |
| time step | | First second or third litter bag retreival |
| month | months | Months since litter bag was put in soil (at 5 cm depth). Litter bags were installed in August of 2011 |
| # spc in bag | number | Number of species put in litter bag (representative of dominant vegetation in habitat) |
| Elevation | meters at sea level | Elevation measured by a hand held GPS device |
| Grav moisture % (t3) | % | From the third litter bag removal, gravimetric moisture calculated as a function of moisture in the freshly collected bag - dry weight of bag |
| WTD 2013 | cm | Mean growing season water table depth measured manually each week in 2012 and 2013. Negative means water table was below the surface while positive means above the surface |
| pH | unitless | Mean growing season pH measured manually each week in 2012 and 2013 |
| cond | mg/L | Mean growing season conductivity measured manually each week in 2012 and 2013 |
| temp | degree celcius | Mean growing season soil temperature at 10 cm depth manually each week in 2012 and 2013 |
| pH sd | unitless | standard deviation (see details above) |
| cond SD | mg/L | standard deviation (see details above) |
| temp SD | degree celcius | standard deviation (see details above) |
| TC | mg/L | total carbon concentration of pore water collected weekly and averaged for the growing season in 2012 and 2013. Analyzed using a shimazu analyzer |
| TN | mg/L | total nitrogen concentration of pore water collected weekly and averaged for the growing season in 2012 and 2013. Analyzed using a shimazu analyzer |
| C:N | unitless | ratio of TC:TN in the pore water |
| mean loss | % | % mass loss of litter (average of 3 replicate litter bags) |
| sd loss | | standard deviation (see details above) |
