Olympic swimmers aren’t the only ones who change their strokes to escape competitors. To escape from the jaws and claws of predators in cold, viscous water, marine copepods switch from a wave-like swimming stroke to big power strokes, a behavior that has now been revealed thanks to 3-D high-speed digital holography.
A team of Arctic researchers led by the University of Texas Marine Science Institute's Ken Dunton will embark on a comprehensive study of the Hanna Shoal ecosystem in the Chukchi Sea off Alaska's northwest coast with a $5.6 million grant from the Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE).
Whether a large area of low oxygen water called the "dead zone" in the northern Gulf of Mexico could cause declines in environmentally and economically important fish populations is the subject of a new study by University of Texas at Austin marine scientist Peter Thomas.
Groove-like tracks on the ocean floor made by giant deep-sea single-celled organisms could lead to new insights into the evolutionary origin of animals, says biologist Mikhail "Misha" Matz from The University of Texas at Austin.
