Phytoplankton blooms, aside from giving us gorgeous eddies of blue and green, can reveal how ocean currents are mixing. Blooms typically occur where nutrients are being washed together. #

How to Grow Straight Icicles
New research suggests that icicles grow straighter when exposed to moving air while exposure to still air can cause icicles to sprout at their tips. To grow icicles, the researchers built a refrigerated box that dripped water from the top while the growing icicle rotated. Understanding ice growth is important for flight aerodynamics and icing on airplane wings. For videos and more on icicle growth, see the article at Wired Science. #
Can a Squid Fly?
Evidence is mounting that several kinds of squid will use jets of water to propel themselves into the air where they can actively fly some 50 times their body length.
Turbulent Mixing in the Gulf
Sediments carried by rivers and stirred from the shallows meet the Gulf of Mexico in a vivid display of turbulent mixing. Although turbulence is not well-understood, it is a process vital to our lives. Without turbulence, it would take days for molecular diffusion to mix milk into your coffee! #
Liquid Umbrella
Droplet collisions, usually with water or milk, are popular with photographers for their artistic value. As stunning as these still images are, high-speed video makes the effect even better.
