How do i turn off email notifications on my laptop? I keep getting email's notifying me of my upcoming meetings. This would be fine, but i never asked it to do this. 

I use Gmail for email and Google Calendar for my scheduling. On my laptop Mail.app and iCal are linked to my Google account although I never use either of them. 

Can someone point me in the right direction for turning email notifications off?
sign in to google calendar at http://google.com/calendar
Click on the 'gear' icon at the top right and choose 'Calendar Settings'
Click on 'Calendars' 
Click on 'Notifications' for the appropriate calendar
look for 'Event reminders' and remove the 'By default, remind me via [Email]' entry
