Hi,
I have a df like this one and I would like to do a multiple filter on this. I need to select my Env data per station but also per a specific depth.
Like I want to filter to have the Env data for the station 1 but only at 250m, the station 2 I want the Env data at 190m etc.
How can I do this "multiple filter"
Thanks
