Question about music in Master and Commander

I just saw Master and Commander earlier today, and I have a question about the music used in it. Does anyone know what piece of music was played in the scene in which the crew of the Surprise first goes to the Galapagos (sp) Islands?
I believe the song was also used in a Gatorade commercial a few months ago. If my memory serves correct, the commercial depicted athletes filmed in slow motion.

It’s the Cello Suite #1 in G, by J.S. Bach.

Thanks, Wumpus.
