Adventures in Polar Research● Spectroradiometer - measures light, and spectral quality of light● Understand green light, red light, ● Algae that attaches themselves to ice crystals begin to grow - a lot of biomass created under austere ice ● Drilling ice cores for information● Ice falls on more solid ice● Becomes massive feed for all organisms that couldn’t reach algae● Microscopes: see diomes● Packed with pigment to capture any photon of light so has energy necessary to fix carbon and grow● Electron microscope - even more detailed● When you’re sick, nutrients in your throat cause bacteria to flock there, create glue, and stay. ● Q: do you believe in global warming?● A: no, it’s not about belief; scientific evidence shows that it’s happening.● * make sure the quality of science is better than when you arrived● * defend the funding to congress● Weddell seal, female + pup●● Documented/photographed the sea ice around Alaska melting, and expanding○ When it melts, more heat gets into the ocean○ Caverns under the surface, where seals would swim○ Scientific instrument is photography - new questions opened by photos● Sea ice is major habitat for polar flora & fauna○ Ex: In the Antarctic, krill actually go up to ice and scrape for food●○ Different colors generated from fungi and bacteria that seep into the porous rock,to find place to land● Pulver Plateau●● Tend to go to southpole end of Sept/early Oct - when it’s warmer. Stay till Feb when getscold. ○ It can get to 140 below zero.○ thus a great place to study similarities to other Extraterrestrial life.● Astronomers + Astrophysicists go to south pole to see the universe, as carbon monoxideis usually all frozen away.● Amundsen Scott South Pole Station is an international community of scientists and researchers. Since 1970s.● *no need to know about Ozone layer● * ice cores ice of the sea ice. So no need to know material not covered by Sullivan in lecture. ● Sea ice microbial community - the community that lives attached to sea ice (not very diff from microbial community in the soil. Cool because can be observed the way you can’t in
