5 | 13 |
|
6 | 14 | This project is dedicated to study the impact of mesoscale eddies on |
7 | 15 | forage fauna at global scale. This GitHub repository provides the code |
8 | 16 | of the Receveur et al. (2024) publication in Nature Communication. |

| 40 | +## Workflow |
| 41 | + |
| 42 | +The analysis pipeline follows these steps: |
| 43 | + |
| 44 | +1. Download eddy data |
| 45 | +2. Download acoustic data |
| 46 | +3. Overlap the two data sources to only keep acoustic data inside and |
| 47 | + around eddies |
| 48 | +4. Make and Export the Figures 1 and 2 |
| 49 | +5. Compare inside acoustic values to outside acoustic values in each |
| 50 | + eddy |
| 51 | +6. Make and Export the Figures 3 and 4 |
| 52 | +7. Compare the spatial distribution of the results with the previously |
| 53 | + published results |
| 54 | + |
| 55 | +## Content |
| 56 | + |
| 57 | +This repository is structured as follow: |
| 58 | + |
| 59 | +- [`data/`](https://github.com/auroreRECE/eddy_micronecton/tree/main/data): |
| 60 | + contains a sampled of data used in the article. The folder is split in |
| 61 | + two folders: |
| 62 | + [`data/raw/`](https://github.com/auroreRECE/eddy_micronecton/tree/main/data/raw) |
| 63 | + to find a sample of all raw data (acoustic, eddy trajectories, chloro |
| 64 | + and sst) ; and |
| 65 | + [`data/intermediate/`](https://github.com/auroreRECE/eddy_micronecton/tree/main/data/intermediate) |
| 66 | + with some intermediate .Rdata files, to make easily the Figures. |
| 67 | + |
| 68 | +- [`figures/`](https://github.com/auroreRECE/eddy_micronecton/tree/main/figures): |
| 69 | + contains the figures used to validate et visualize the outputs. |
| 70 | + |
| 71 | +- [`scripts/`](https://github.com/auroreRECE/eddy_micronecton/tree/main/scripts): |
| 72 | + contains R scripts to run the workflow. The order to run these scripts |
| 73 | + is explained in each name of files and follow the Workflow |
| 74 | + description. |
