Pony for a Professor

HAH! This isn't FiM-related, so it goes in my regular account.
THAT'S RIGHT, IT'S NOT FANART BUT I'M STILL SPAMMING YOU WITH PONIES ANYWAY! For such is my power... my destiny!

I had some questions about data in ice cores from Greenland. So I emailed one of the researchers involved in the GISP project and he was kind enough to answer back and clarify the issue for me. I promised to draw him a pony if he replied, and apparently nobody can turn down a (picture of a) pony.
Thanks, Dr. Alley!
