The physics of flotsam
1) Using the map provided above and the definition of gyre, how many gyres does the earth have? use the ocean they are located in to list them.
Indian - 1
South Pacific - 1
North Pacific - 2
North Atlantic - 1
South Atlantic - 1
2) If one degree of latitude is equivalent to 69.047 statute miles, how many miles across is the central north pacific gyre? using the map, estimate the surface area of the gyre.
Its about 110475.2 miles
3) If the surface of the California Current flows at approximately 1 km per hour, how far will a piece of marine debris move in 1 week?
it will move 168 km in a week
4) The north pacific current is warmer and faster than the california current. it travels at the speeds in the hundreds of kilometers per hour. SEAPLEX observers collected bottles written in korean and chinese (in addition to english). if the bottles floated across the pacific ocean from asian shores, what is the least amount of time the bottles were in the water?
The least is 17 hours. hundreds = 999
5) if the pacific ocean is approximently 17,000 km from east to west, how many days would it take the research vessel, new horizon, traveling at a maximum speed of 10 knots to cross it? (1 knot = 1.852 kilometers per hour). ignore water current influences on speed
