Tropical calanoid copepod stable isotope data from the Mexican Pacific

Stable isotope values (δ¹⁵N and δ¹³C) of 20 calanoid copepod species, 3 zooplankton size fractions and seston were assessed from samples obtained monthly between January and December 2012 at a coastal sampling site in the Eastern Tropical Pacific off Mexico (19°09'03\" N, 104°44'50\" W).2012年1月至12月，研究人员在墨西哥外海热带东太平洋沿海采样站点（地理坐标：北纬19°09′03″，西经104°44′50″）按月采集样本，对其中20种哲水蚤目桡足类(Calanoid copepod)、3组浮游动物粒径分级样品以及悬浮颗粒物(Seston)的稳定同位素值——氮同位素比值(δ¹⁵N)与碳同位素比值(δ¹³C)——进行了测定分析。
