| 6 feet | fathom |
| used on a boat to home in on different radio beacons to find your location when lost | RDF |
| problem caused by not drinking enought fresh water | dehydration |
| water in a gas form | water vapor |
| a chart that covers a large area but doesn't show much detail | small scale chart |
| a chart that covers a small area in a lot of detail | large scale chart |
| if something will float or sink in water depends upon it's a) weight b) density or c) pourosity | b)density |
| percent of Earth covered by oceans | about 75% |
| where life began on Earth | ocean |
| what are the 2 main ways that people effect the ocean | pollution & over fishing |
| name 4 characteristics that help identify humpback whales from other types of whales | 1) big white flippers 2) small dorsal fin 3) bumpy head and chin 4) black & white pattern on bottom of fluke 5) way it humps its back when diving |
| where do the humpbacks spend the winter | Caribbean |
| what do the humpbacks do in the winter | mate, give birth, sing |
| where do the humpbacks spend the summer | N. Atlantic |
| what do the humpbacks do in the summer | eat |
| what are the 4 major purposes of the mission | 1) count the whales, 2) study their environment, 3) identify individual humpbacks, 4) study their behavior |
| how do scientists tell different humpbacks apart | scientists use the black & white patterns as well as the scars and notches on the bottom of the humpback's flukes to tell one from another. They look up the pattern in their book or on a computer. Each pattern is unique. |
| How does a baleen whale get its food | baleen whales take in a mouthful of water and fish then strain out the water through their baleen |
| name 3 reasons why the Right Whale was the right whale to hunt | 1) had lots of oil, 2) floated when killed, 3) slow therefore easy to kill, |
| examples of how the Mimi crew were able to deal with problems | 1) lead line for depth sounder, 2) RDF had own batteries, 3) use bread and stopwatch for knotmeter, 4) had tools to fix boat, ... |
| how does the Seasat satellite measure the ocean depth | by measuring the height of the water, water bunches up over underwater mountains and dips over trenches |
| name 3 ways dolphins are suited for ocean life | 1) contour body that flows through the water easily, 2) eyes that see above and below water, 3) layer of fat to keep them warm, 4) smooth skin, nearly hairless, 5) breath through blowholes, 6) flat tails propell them swiftly |
| why are dolphins well suited for aquarium shows | they are used to living in shallow water and maneuver easily |
| what happens to humpback songs | they change each year |
| what do humpbacks eat | small fish, krill, sand lance |
| what happens to the temperature of water as you go deeper | it gets colder |
| why is cold water at the bottom of a lake or ocean | cold water is denser and sinks to the bottom |
| name 4 reasons whales are considered mammals and not fish | 1) breath air in lungs, 2) nurse their young, 3) give live birth, 4)has hair |
| name 4 reasons why scientists believe that the ancestors of whales were land animals | 1)some whales have pelvic bones, 2) they are mammals and all other mammals evolved on land, 3) flipper structure is like a hand, 4) fossil record shows blowhole has moved |
| 4 things that are recorded during a census run | 1) time, 2) bearing, 3) sighting cue, 4) behavior, 5) species |
| why do whales group together in certain areas of the ocean in the summer | they group together where their food is located |
| what was the major discovery made by the Mimi crew about humpbacks | that the scars and notches stay the same but the black and white pattern changes over time, over a period of time it could be mistaken for a different whale |
| how does a solar still work | heat from the sun warms up the salt water causing water to evaporate, water vapor rises then condenses on the cool plastic and runs down into the cup as fresh water |
| advantages of old whaling methods | slow process therefore not many whale were killed |
| advantages of new whaling methods | less painful for the whale being killed |
| disadvantages of old whaling methods | very painful for the whale being killed |
| disadvantage of the new whaling methods | a lot of whales can be killed quickly |
| ...---... | Morse Code for SOS |
