18 January, 2002MAGGIE GETS DRESSED! Maggie Amsler is a scientist at the University of Alabama, Birmingham. She is studying the chemical ecology of marine plants and animals. She is looking to see how plants and animals defend themselves from being eaten by others. In order to do this work, Maggie dives in the chilly waters of the Palmer Station region. When Maggie is checking her underwater experiments, she usually dives to a depth of 20 feet. When she is collecting plants and animals, however, she often has to go to a depth of 120 feet. She is underwater for an average of 25-30 minutes at a time. She always has a diving "buddy" with her. While they are in the water, there is a Zodiac above them, with two people in it. These people are the "dive tenders." At least one of them must be certified in special emergency training for divers. As you would guess, the water is cold! Right now it is about 1° Celsius. So, Maggie wears a lot of layers of clothing to protect herself from the cold! Maggie wanted to know just how much she weighs when she is wearing all her diving equipment. So, I took photos and kept records while she put on all the layers. Here's the math: how much weight gain was there between each step? Which step had the greatest weight gain? When Maggie is all dressed, how much weight has she added? What percentage is that of her original weight? What is 1° Celsius on the Fahrenheit scale?
