Organic and Inorganic Nutrients in the North Pacific from the 2016 cruise KOK1606 (Gradients 1)

<p>Data on organic and inorganic nutrients in unfiltered seawater that was sampled aboard the Gradients 1&nbsp;cruise (KOK1606) in April/May 2016&nbsp;along a transect from Hawaii to 37&nbsp;degrees north along a longitude of 158 degrees west. Seawater was collected into HDPE or polypropylene bottles and immediately frozen. Silicate, phosphate, nitrate+nitrite and ammonium are determined colormetrically on a SEAL Analytical Autoanalyzer (AA3 with HR detectors), with the exception of nitrate+nitrite that is &lt;0.5umol/L, which is analyzed by chemiluminescence. Total organic carbon is determined by combustion on a Shimadzu TOC-V analyzer.</p>
