What Depth Should Deep-Sea Water be Pumped up from in the South China Sea for Medicinal Research

In this study, seawater was pumped up from 150, 200, 300, 500 and 1000m in the South China Sea and analyzed to make certain what depth should deep-sea water （DSW） be pumped up for medicinal usage. The pumping depth of DSW was determined on the basis of chemical ingredients. The analyses of inorganic...

More Information
Summary:In this study, seawater was pumped up from 150, 200, 300, 500 and 1000m in the South China Sea and analyzed to make certain what depth should deep-sea water （DSW） be pumped up for medicinal usage. The pumping depth of DSW was determined on the basis of chemical ingredients. The analyses of inorganic elements and dissolved organic matter （DOM） were performed by inductively coupled plasma mass spectrometry （ICP-MS） and ultra performance liquid chromatography-mass spectrometry （UPLC-MS） respectively. The raw data were used for hierarchical cluster analysis （HCA） and principal component analysis （PCA）. The results showed that seawater pumped up from 500m and 1000m was similar in their chemical ingredients, and was different from the seawater pumped up from other depths. These results indicated that seawater from more than 500 m depth had relatively stable chemical ingredients and could be used as DSW in the South China Sea.
