Water column biogeochemical data from Mercer Subglacial Lake

This dataset contains water column biogeochemical properties measured on discrete samples collected from Mercer Subglacial Lake by the SALSA project. Data included are: specific conductance; carbonic acid system parameters (total alkalinity, total inorganic carbon, and pH); water stable isotopes (δ2H and δ18O); dissolved gases (oxygen, methane, nitrous oxide, and hydrogen); dissolved nutrients (ammonium, nitrite and phosphate), major anions (including nitrate) and cations; size-fractionated colloidal and dissolved trace elements); dissolved organic carbon; and microbial cell and virus-like particle counts.本数据集包含由SALSA项目（SALSA Project）从默瑟冰下湖（Mercer Subglacial Lake）采集的离散水样中测得的水柱生物地球化学特性。所涵盖的数据包括：比电导率；碳酸体系参数（总碱度、总无机碳及pH）；水体稳定同位素（δ²H与δ¹⁸O）；溶解气体（氧气、甲烷、一氧化二氮与氢气）；溶解态营养盐（铵、亚硝酸盐及磷酸盐）、主要阴离子（包括硝酸根）与阳离子；分级粒径的胶体态与溶解态痕量元素；溶解有机碳；以及微生物细胞与类病毒颗粒计数。
