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.
The normal range for an adult urinary output is between 400 to 2,000 mL of urine daily -- with a normal fluid intake of about 2 liters per day.Values for normal urinary output may vary slightly between laboratories. A urine output of 500 mL per day is generally considered adequate for normal function.Factors other than kidney disease that can influence how much you urinate in a day include how much water you consume, the amount of fluid lost in perspiration, your caffeine and alcohol intake and any medications you've taken. urine output of 500 mL per day is generally considered adequate for normal function.
