Carbon Balance in Warming and Drying Tundra

HEY MR. WOOD

 IT'S RILEY FROM PERIOD.  WE ALL MISS YOU SO MUCH AND WISH YOU WERE HERE.  WHAT HAS IT BEEN LIKE TO SHARE A SMALL REMOTE CABIN WITH SO MANY PEOPLE?  HOW WAS IT LEARNING HOW TOT RIDE WITH SLED DOGS?

Hello and thanks for the good questions. The cabin can get a bit cramped, but everyone is very nice and we all have our own little space to sleep and work. Learning to ride a dog sled is pretty exciting and fairly easy. The first thing to remember is to hang on!! The dogs really take off at first, then you just need to watch out for trees to knock you off or the sled tipping over. I have come off a couple of times, but nothing big.Cheers,
Mr. Wood

DEAR MR. WOOD THIS IS RILEY FROM PERIOD 4, I CHOOSE TO DO ARCTIC SEA ICE.
Q:WHAT CAN WE DO TO KEEP THIS FROM HAPPENING?
A:WE CAN PUT LESS CHEMICALS LIKE BURNING FOSSIL FUELS AND POLLUTING OUR AIR, WE CAN ALSO HELP PREVENT CHLOROFLUOROCARBONS.
Q:IF WE CAN'T PREVENT IT THEN WHAT WILL HAPPEN IN 100 YEARS?
A:IF WE CAN'T PREVENT IT THAN I PREDICT THAT IN 100 YEARS WE WILL HAVE VERY LITTLE TO NO SEA ICE ON OUR PLANET, AND OUR SUMMERS WILL GRADUALLY GET HOTTER.
BEST LUCK TO ALL

DEAR MR. WOOD, I'VE TOLD SO MANY PEOPLE ABOUT YOUR EXPEDITION. I WENT TO VISIT MY LITTLE SISTERS SCHOOL, AND TOLD THE FIFTH GRADE TEACHERS THERE ABOUT POLARTREC AND YOUR EXPEDITION. I ALSO HAVE AN AUNT WHO TEACHES SIXTH GRADE AT ALBERT SCHWEITZER ELEMENTARY SCHOOL.
GREAT QUESTION ON YOUR LATEST JOURNAL. IT TOOK ME A WHILE TO THINK ABOUT MY ANSWERS. THEY WERE A REAL BRAIN TEASER.
Q:HOW MUCH CO2 IS THE GRAPH SHOWING?
A: I THINK THAT THE GRAPH IS APPROXIMATELY SHOWING 388 PARTS PER MILLION.
Q:WHAT TIME OF DAY WAS THIS DATA COLLECTED?
A: I BELIEVE THAT THIS DATA WAS COLLECTED BETWEEN THE HOURS OF 11 AM TO 1PM. THE REASON FOR MY DECISION IS BECAUSE LOOKING AT THE PAST JOURNALS THE NUMBERS WERE HIGHER AT NIGHT THAN IN THE DAY. THEREFOR I MADE A HYPOTHESIS BASED ON THE TIME RECORDINGS FROM THAT SET OF DATA.
Q:IN TWO HOURS, WHEN THE NEXT SAMPLE WILL BE COLLECTED, WILL THE AMOUNT OF CO2 LEVEL MOVE UP OR DOWN. WHY?
A: I BELIEVE THAT THE THE CO2 LEVEL WILL MOVE DOWN AS THE SUN GOES UP, AND UP AS THE SUN GOES DOWN. THE REASON FOR MY ANSWER IS BECAUSE OF WHAT YOU TOLD US, THAT THE PLANTS DO NOT CONDUCT PHOTOSYNTHESIS IN THE NIGHT. THAT LED ME TO THINK THAT THE PHOTOSYNTHESIS WILL TAKE PLACE WHEN THE SUN IS UP. THERE FOR IT WILL DOWN IN THE DAY AND UP IN THE EVENING AND NIGHT.

That is wonderful thinking on your part. You have a good understanding of what's going on here. Thank you so much for sharing this expedition with the other students and teachers. Your aunt did post a comment. I hope she keeps following. You are the first one with an answer! I think you have a future in science!Cheers,

Dr. Mr. Wood,,,Here are the answers for the questions that Mr. P asked;
Q: What factors cause this area to be Tundra?
A: The factors that cause this area to be Tundra are, latitude, altitude, and distance from large bodies of water.
Q: How will the factors change with a warmer climate?
A: The factors will change in a warmer climate by having more plants earlier in the year, less snow in winter, and more sun and warmer weather throughout the year.
Q: Why are there no large trees in the Tundra area?
A: There are no large trees in this area due to the Tundra being frozen and the tree roots not being able to grow under the ground. The two most common trees that grow in Alaska are the Black and White Spruce trees.
