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. Normal: 1.005-1.030. Abnormal: A very high specific gravity means very concentrated urine, which may be caused by not drinking enough fluid, loss of too much fluid (excessive vomiting, sweating, or diarrhea), or substances (such as sugar or protein) in the urine.bnormal: Red blood cells in the urine may be caused by kidney or bladder injury, kidney stones, a urinary tract infection (UTI), inflammation of the kidneys (glomerulonephritis), a kidney or bladder tumor, or systemic lupus erythematosus (SLE).
