Thanks, Janet and Randi.
This was a tough TWYS decision for me because I couldn't type 'degrees', but could type 'minutes.' I pondered several hybrid entries and finally decided to ask for expert advice! As you can see, in the meantime, I went with decimal entries.
The first few pressure observations they made after the arrival of the barometer were also recorded as degrees/minutes; once I saw that they 'corrected' themselves, I kept on transcribing. I await the scientific crew's advice for any edits.
