I am suddenly seeing I have over 700MB of data on some days being sent while I am online. I notice this in Activity Monitor. These are days when I do very light browsing and less than ten emails w/o attachments.

What can I do to find out exactly what and where all this data is being sent from?

Thank you for looking.

Use a packet sniffer or install Little Snitch.
I think you can try it free for three hours which should be enough for you to see where your data is going.
