  1. ThursdayFebruary 28, 2013 (James Cameron’s Dive; Continue Video WS – Deep Ocean)

  2. The Launch Pad Thursday, 2/28/13 What happens to the water pressure, temperature, and light levels as you dive deeper and deeper under the sea, and why? Water pressure increases because more and more water is above you and is pressing down with its weight. Temperature and light levels decrease because there is less and less solar radiation as you go deeper.

  3. Announcements ?? • Happy National Chili Day!

  4. Announcements I will not be available after school today.

  5. Recent Events in Science NASA's Aquarius Sees Salty Shifts Read All About It! Colorful new images chronicle the seasonal stirrings of our salty world: Pulses of freshwater gush from the Amazon River's mouth; an invisible seam divides the salty Arabian Sea from the fresher waters of the Bay of Bengal; a large patch of freshwater appears in the eastern tropical Pacific in the winter. These and other changes in ocean salinity patterns are revealed by the first full year of surface salinity data captured by NASA's Aquarius instrument. www.sciencedaily.com/releases/2013/02/130227165152.htm NASA¹s Aquarius instrument has been orbiting the Earth for a year, measuring changes in salinity, or salt concentration, in the surface of the oceans. The Aquarius team released last September this first global map of ocean saltiness, a composite of the first two and a half weeks of data since the instrument became operational on August 25.

  6. They were both created by film director James Cameron. What do the movies Titanic and Avatar have in common?

  7. On March 26, 2012, Cameron reached the bottom of the Mariana Trench, the deepest part of the ocean, in the Deepsea Challenger submersible.He was the first person to do this in a solo descent, and only the third person to do so ever.

  8. Cameron dove to a depth of 35 756 feet (6.77 miles), to the bottom of the Challenger Deep in the Marianas Trench, the deepest spot in the world’s oceans. It was only the second time in history that man had visited this spot, the first being 53 years ago, in 1960.
