Indeed you can!
I'm very happy that you are continuing!
Note that here we do want a full transcription.
However, it looks like they are in port most of the time, so it will be pretty much what you have been doing.
BTW Today I was doing a crossword puzzle and the clue was something about a Los Angeles port area. The solution was San Pedro!
On 1947-9-11 (and a couple other dates), there is an extra weather observation logged in the blank line between 1200 and 1300. Should I be noting that somehow?
It looks to me like it's the typist. You can see that the wind direction at 1200 looks funny (255 when it was probably 355 - but leave it as it is). I would just leave that line out. You could add a Transcriber Comment/Weather Record for 1200 to note that there was an extra line. Leaving that line out won't make any significant difference to anything.
