Oceаnоgrаphers interested in the effects оf rising temperаtures glоbally found historical data of ocean temperatures off Cabo San Lucas from the 1950s. In order to test the hypothesis that water temperatures have risen since then, they repeated the measurements from the years 2000-2010. Ocean temperature was measured at a coastal station on January 1 of every year from 1950 to 1960, and again from 2000-2010. The data are presented here in a graph format with standard deviations represented by the error bars. Accessible description of imgae: Bar chart titled “Average Ocean Temperatures” with the y-axis labeled “Average Temperature (°F)” ranging from 40 to 80 degrees. Two bars compare time periods 1950–1960 and 2000–2010. The 1950–1960 bar is just under 70°F, while the 2000–2010 bar is slightly above 70°F, with small error bars shown on both bars, indicating a slight increase in average ocean temperature over time. What was the approximate mean ocean temperature 1950-1960?
Scenаriо Kenneth аnd Cаtherine Lоhmann оf the University of North Carolina explored the orientation ordirection-finding abilities of loggerhead sea turtle hatchlings under varying magnetic conditions.Hatchlings were placed in a tank of water in a laboratory either in the natural magnetic field ofthe earth OR in a reversed magnetic field in which north and south were flipped. Theresearchersthen measured the direction that the hatchlings swam. The experiments were carried out in thedark and at night since that is when most newly hatched turtles migrate from their sandy nestsinto the ocean. What is the variable being tested in this experiment?
