Surface transects for arsenic speciation, antimony speciation, and alkaline phosphatase activity from R/V Knorr cruise KN204-01 in the Subtropical North Atlantic Ocean in 2011 (U.S. GEOTRACES NAT project)

<p>Surface transects for arsenic speciation, antimony speciation, and alkaline phosphatase activity</p>

<p>Data for the concentrations of the dissolved (&lt;0.4 µm) arsenic species: total inorganic As (III+V), arsenite (AsIII), As(V), monomethyl As, dimethyl As,&nbsp; and the activity of the enzyme alkaline phosphatase (unfiltered).</p>

<p>Please note that some US GEOTRACES data may not be final, pending intercalibration results and further analysis. If you are interested in following changes to US GEOTRACES NAT data, there is an RSS feed available via the BCO-DMO <a href=\"http://www.bco-dmo.org/project/2066\">US GEOTRACES project page</a> (http://www.bco-dmo.org/project/2066; scroll down and expand the \"Datasets\" section).</p>

<p>用于砷形态分析（arsenic speciation）、锑形态分析（antimony speciation）以及碱性磷酸酶活性（alkaline phosphatase activity）检测的表层断面数据</p><p>本数据集包含溶解态（<0.4微米）砷形态物种的浓度数据：总无机砷（三价+五价）、亚砷酸盐（AsIII）、砷酸盐（As(V)）、一甲基砷、二甲基砷，以及未过滤的碱性磷酸酶活性数据</p><p>请注意，部分美国GEOTRACES（US GEOTRACES）数据尚未最终定稿，仍需等待相互校准结果与进一步分析。若您希望追踪美国GEOTRACES NAT数据的更新动态，可通过BCO-DMO的<a href="http://www.bco-dmo.org/project/2066">美国GEOTRACES项目页面</a>（http://www.bco-dmo.org/project/2066；向下滚动并展开"数据集"板块）获取RSS订阅源。</p>
