Whenever you can during the week. Some questions don't show up until the next day, so your answers may be a day or two coming.Thanks,
Mr. Wood

Jonathan Palafoutas: That last comment was me sorry. Also, I think that the CO2 levels would drop at that time of year. The temperature is cold and dark so the plants aren't as active. This is just a hypothesis, but the thick blanket of snow might act as a CO2 sponge. When the plants die, they release CO2, but that may just get trapped in the snow blanket. So when it melts in the summer all the CO2 is released creating even more CO2 in the atmosphere making the plants more active creating even more CO2. Similar to the Permifrost positive feedback. The time of day also plays a big roll; light increasing increases plant activity, but the blanket of snow may stop that. When it is night, there is even more darkness so the plants are probably not active at all.

Good thinking. Keep in mind that the plants do not release CO2 when they die, the decomposers that work on them do. The plants do not photosynthesize now even on sunny days because they are buried under snow. Some CO2 is trapped in the snow, but not large amounts that get released later.Keep up the good work,
Mr. Wood

What food do you eat up there? Any Snickers?

Thank you for asking, but this really doesn't count as a question. I eat pretty regular food, but no we are out of Snickers!Read the journals and ask something better, please.

I think that there would be less co2 because the plants are not as active in dark lighting. When plants die do they release co2? And are decomposers more active in the day or night?

Hello. There would not be less CO2, why? Plants do release CO2 after they die when they decompose.Thanks,

Jonathan agian, and can the auras affect earths magnetic field in any way? Are they a form of heat that can melt ice?

From the assembly, I learned more about where you were, I learned that there aren't a lot of organisms beneath the permifrost, I learned more about what happened in the videos with the hot water and bubbles because my I Pad wouldn't let me watch them, and I learned more about what you are doing in the experiment.

I think that you can study nature without changing it. If you just look at it, nature probably won't be affected, but if you use machinery, it can be affected by gases, electromagnetism, chemicals, infrared and ultraviolet lights, ect., it will be.

Good thinking. Thanks for the question at the PolarConnect event.Thanks,
