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.
Specific gravity, in the context of clinical pathology, is a urinalysis parameter commonly used in the evaluation of kidney function and can aid in the diagnosis of various renal diseases.
