pod_data

Download long-term POD datasets from ETN-underwater acoustics using the R package lwdataexplorer. Minute data is queried per ~10 days to avoid server-related issues.

To access lwdataexplorer datasets, your ETN credentials (userid and password) must be filled in a .Renviron file. These credentials can be found when you log into the ETN Data Platform. In the top right of the platform, click your name and choose "ETN R access." See your credentials to connect to the ETN database.

Full tutorial to configure your credentials: https://inbo.github.io/etn/articles/authentication.html

The script is divided into the following steps:

  1. Download and check data per year. Subset data to certain projects or stations and quality control each field.
  2. Standardize minute-resolution datasets for data publication (e.g. to MarineInfo, https://www.vliz.be/en/imis?module=dataset&dasid=8999).
  3. Aggregation of data into hourly resolution.
  4. Conversion of data into a DwC-A structure for EMODnet Biology and OBIS, which is composed of three files (event, occurrence and emof).
  5. Quality control the DwC-A structure.
