The goal of sooty is to provide data of interest to Southern Ocean research.
At the moment we only return lists of files available in object storage, but future versions will provide direct access to the data in these files with helper functions defined here.
To see what files we have in object storage, use
library(sooty)
(files <- tibble::as_tibble(sooty_files()))

In time we will provide helpers to pick specific data sets and open data for a given date.
For now we only have manual handling, such as
