Spatially, the marine environment is divided into the pelagic division and benthic division. Being pelagic means to be in the water, surrounded by water at any depth.The pelagic division above the continental shelf is distinguished as the neritic province from the pelagic area above the open ocean (abyssal plain, oceanic ridges/rises, and trenches) which is call the oceanic province.eing pelagic means to be in the water, surrounded by water at any depth.

Normal specific gravity range in urine. The normal range of specific gravity in human urine is from 1.003 to 1.030. Values outside this range may be the result of specimen dilution, adulteration or may be indicative of a number of health related problems.
A urine sample is a painless way for your doctor to evaluate your health and test for abnormalities. One thing your doctor may check for in your urine sample test (urinalysis) is specific gravity. A urine specific gravity test compares the density of urine to the density of water.This quick test can help determine how efficiently your kidneys are diluting your urine.Urine thatâs too concentrated may indicate that your kidneys arenât functioning properly, or simply that you arenât drinking enough water. urine specific gravity test compares the density of urine to the density of water.
