# Dead Zone Mapping

## Code

- https://code.earthengine.google.com/?accept_repo=users/yingjieli/DZT

- **01_DO_dataset_cleaning.Rmd**

- **02_DO_format_for_model.Rmd**

- **03_spectral data at sampling locations.Rmd**

  

  To clean the data downloaded from GEE, and to link the image band info with DO data. 

  

  

## Data

```

    |__ data_for_gee

    |   |__ sample_2000_2019_DO.xlsx     *(DO data at all depth levels)*

    |   |__ sample_2000_2019_DO_min.xlsx *(min DO at one location across the profile)*

    |
