downwell

Definitions

1. To sink below material of lower density.
2. To penetrate water downward.

Examples

“Some of the northward-flowing waters turn⟳ eastward and enter⟳ the Throughflow sponge above 1300 m (Figure⟳ 5b), where they downwell and return⟳ to the interior and spread⟳ both to the south and the north (Figure⟳ 5c).”

“Ozone in the upper troposphere which downwells to the surface can also result⟳ from photochemical production enhanced by high levels of NOx from the natural stratosphere, aircraft emissions of NOx in the upper troposphere [Liu et al., 1980],”

“This cold water downwells and flows below the saltier but warmer surface water.”

“This measurement, as Region 4 stated, has been "commonly used to measure⟳ marine turbidity; it does not measure⟳ downwelling ambient light⟳."”

“There is a practical depth limit⟳ from which the radiance is reflected. Gordon & McCluny (1975) call⟳ the depth at which the spectral radiance downwelled from the surface falls to 1/e of its initial energy 'the first optical attenuation length'.”

“For those animals living in the mesopelagic zone, where some light⟳ downwells from the surface, a visual predator looking up at them could see⟳ a silhouette.”

“In other words, the signal always weakens while it downwells.”
