Hey whats up its Zach from Flagstaff Arizona,how  are you doing im doing well. in my class in science in the pond. we are measuring the depth and perimeter of the pond. also we tested for ecoli and some other chemicals inside the water. we made a sediment trap to put in the water and were going to put it in the water and see if it catches sediments.

i was wondering is the water in the antartic fresh or does it have chemicals in it. how many months at a tiime are you gone when you go tyo the antartic.
