  • Description:
    "At the end of a Sept. 2010 mission on board the NOAA Ship Pisces, researchers attached a few styrofoam cups to the CTD (conductivity, temperature, depth) device prior to lowering it into the water. Since the pressure at the depths of the CTD casts is much greater than at the surface, the air is squeezed out of the air pockets in the styrofoam, compressing the cup to about a quarter of its original size. Mission scientists said that their research seems to indicate that the same pressure that causes the cups to shrink has also played a role in the fate of the natural gas that was emitted with the oil from BP's Macondo well. While natural gas is lighter than water and might be expected to rise to the surface, it seems that the enormous pressure of the 5,000 feet (1,524 meters) of water above the well exerts enough force to cause much of the natural gas to dissolve into the deep ocean instead. Visit the Pisces online mission log for more details about the voyage. Credit: NOAA"--Deepwater Horizon Response Image Gallery.
