remote sensing
tionary ship, as the distance between source and hydrophone increases.
~seismic instruments, ~seismic survey, ~reflection shooting, and ~refraction.
Refraction shooting (seismic). (After Dobrin 1976)
regenerated production opposite to new production. ~new production.
regeneration the restoration by an organism of tissues or organs which have
been removed (usually by predators).
regression (1) retreat of the sea from land areas by fall of sea level or uplift of
land, and the consequent geographical evidence of such withdrawal, e.g., the
enlargement of the area of deltaic depositions. Regressions may be worldwide as the result of global sea-level fall (~eustasy) or locally caused by uplift
of the land mass involved. Compare transgression, coast; (2) (stat.) relation
between two quantities, established by means of statistical correlation
between paired values of these quantities.
Reineck box sampler/corer the first type of box corer invented by Reineck in 1958 to
collect undisturbed samples of the sediment surface.
relict sediment sediment deposited in a previous period and in equilibrium with
the environment at that time, but unrelated to its present environment even
if it remains unburied by later sediment. Large parts of the North Sea contain relict sediments, deposited during the Pleistocene and Early Holocene.
remote sensing in general this is the technique of obtaining information on distant
objects by electromagnetic (optical or radar) or acoustic signals. Distinction
can be made between active remote sensing where the returning echo of an
artificially generated signal (e.g., radar or echosounding) is measured and passive
remote sensing where naturally occurring signals such as visible light or infrared radiation is recorded. Remote sensing instruments can be mounted in
satellites (~satellite oceanography), in aircraft, ships, moorings or coastal stations.
