But the acoustic fingerprints of twilight zone animals are still mysterious because shipboard sonar don't have the bandwidth to distinguish the many organisms living far below the surface in what's called the deep scattering layer
. It's an area so dense with life that people once thought it was the sea floor.
These rods are elongated along the [q.sub.z] axis and originated from a scattering layer
present at the sample surface.
Their travel pattern coincides with a phenomenon in the ocean known as the deep scattering layer
In this method, a light scattering layer
is added to the initial layer containing titanium dioxide nanoparticles.
So, it is easy to see that information is being gathered from relatively thin surface scattering layer
which is not deeper than 0.5-1 mm, while the major part of information propagates from the top 2-3 transport depths (0.1 mm).
"We wanted to determine the geometry for the scattering layer
that would give us optimal performance," Sun said.
London, January 27 ( ANI ): A geometrically-patterned light scattering layer
designed by McCormick researchers could make solar cells more efficient and less expensive.
Caruso, "Dual-function scattering layer
of submicrometer-sized mesoporous TiO2 beads for high-efficiency dye-sensitized solar cells," Adv.
Yet many whales, dolphins, seals, sea turtles, sharks, manta rays, billfish, and smaller predatory fish are nocturnal hunters, dependent on the mysterious movements of a vast community of organisms known as the deep scattering layer
, or DSL.
This amended model can be used only if the scattering layer
is the uppermost pigmented layer in the multilayer composite coating.
The 'tails' of the curve 2 show fine-period oscillations, indicating the existence of the coherently scattering layer
with the thickness [L.sub.nop] = ([lambda][gamma]h) [DELTA][theta]sin2[[theta].sub.B] ~ 0.5 [micro]m ([[theta].sub.B] = 31.7[degrees] for the 004 InP reflection), yh is the directing cosine.
