Pat Shingleton: "Landslides and Sea Monkeys"

There is no means of predicting landslides but researchers are finding reasons for these deadly shifts of earth. Water Resources Research discovered that landslide risks occur from not only the amount of rainfall but how the rain actually falls. Other ingredients include soil type, depth, vegetation and previous storm damage. All of these ingredients contribute to the redistribution of water. Scientists constructed a revised model that incorporated load distribution behavior and how it changes during different rain patterns such as heavy downpours, light steady rain or sporadic showers. These varying patterns created a difference in the number of simulated landslides, ranging from 30 to as many as 100. Loosened soil ranged from 105.944 cubic feet to 2,118,880. I noticed another article in the Bulletin of the American Meteorological Society reporting on sea monkeys. A study published in Physics and Fluids found that tiny marine organisms could be influencing global sea patterns. Scientists tracked the sea monkeys or brine shrimp by using microscopic glass spheres and lasers to monitor the circulation of the spheres as the shrimp migrated. The study found the shrimp moving vertically, in response to light and rising to the surface during darkness. During daytime hours they went into deeper water. Interestingly, their collective swimming generated water currents comparable to one trillion watts, making them about as influential on ocean circulation as wind or tides.
