# s-gst: about internal tides

<< In certain parts of the ocean, towering, slow-motion rollercoasters called internal tides trundle along for miles, rising and falling for hundreds of feet in the ocean's interior while making barely a ripple at the surface >>

<< Internal tides are generated in part by differences in water density, and created along continental shelf breaks, where a shallow seafloor suddenly drops off like a cliff, creating a setting where lighter water meets denser seas. In such regions, tides on the surface produce oscillating, vertical currents, which in turn generate waves below the surface, at the interface between warmer, shallow water , and colder, deeper water >>

<< Now for the first time [AA] have accurately simulated the motion of internal tides along a shelf break called the Middle Atlantic Bight ... >>

# p-usa: #POTUS race: Donald presidency scares him to death, by Stephen

<< Author Stephen King spoke to Ron Charles, editor of The Washington Post's Book World, during a Facebook Live interview Saturday >>

<< If there's one man who would seem immune to fear, it's Stephen King, the best-selling author and master of horror fiction. But after more than 50 novels, hundreds of short stories and numerous film adaptations of his voluminous work, the 69-year-old still gets spooked >>

<< "A Tump presidency scares me more than anything else," King told Ron Charles [..] "I'm terrified that he'll become president" >>

<<  "I would have laughed three or four months ago, but I think that Trump has a real shot" >>

# s-behav: fertility, in a wide view of an open system

<< Male  peacock  spiders  know  how  to  work  their  angles  and  find  their  light. The  arachnids,  native  to  Australia,  raise  their  derriere  —  or,  more  accurately,  a  flap  on  their  hind end  — skyward  and  shake  it  to  attract  females. Hairlike  scales  cover  their  bodies  and produce  the vibrant  colorations that make peacock spiders so striking >>
