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.

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