 Yes, I talked to an Antarctic specialist whose expedition was canceled because of COVID. And, in fact, he said it might even be delayed two years because they need an extra year to get all the supplies they need down there by ship, and the ship only goes once a year. So science is, well, on edge with the pandemic, as is everything else. Yeah, that's unfortunately exactly what also happened to our group. So I was also supposed to go to Greenland both this year and last year to help with drilling of the ice core, but both of these seasons had to be canceled.
