Physical, chemical and biological CTD and bottle data from R/V Thomas G. Thompson cruise TN278 in eastern tropical North Pacific Ocean from March 19 to April 20, 2012 (NODC Accession 0109846)

This report contains data from R/V Thomas G. Thompson cruise TN278 to the eastern tropical north pacific oxygen deficient zone. The objective of the cruise was to study dentirification and anammox processes. The cruise took place between March and April in 2012 in an area bounded by 26N-14N and 102W-114.5W. Two data sets are included. The first is the 1-meter binned CTD data while the second is the bottle cast data and contains nutrient values for nitrate, nitrite, silicate, phosphate and ammonium. The data were collected as part of NSF grant number OCE-1029316 to Allan Devol. CTD data has been reprocessed and aligned and outliers have been removed. Nutrient samples were filtered (GFF glass fiber) before analysis and analyzed using the US-JGOFS protocols (http://usjgofs.whoi.edu/protocols_rpt_19.html). All data are considered final.

本报告收录了“托马斯·G·汤普森”号（R/V Thomas G. Thompson）科考航次TN278在东热带北太平洋缺氧海域采集的相关数据。本次航次的研究目标为探究脱氮作用（denitrification）与厌氧氨氧化作用（anammox）过程。航次于2012年3月至4月间实施，作业区域介于北纬26°至14°、西经102°至114.5°之间。本数据集包含两类数据：其一为1米分箱处理的CTD（电导-温度-深度仪）数据；其二为瓶式采样剖面数据，涵盖硝酸盐、亚硝酸盐、硅酸盐、磷酸盐及铵盐的营养盐浓度数据。本批数据由Allan Devol牵头的研究团队依托美国国家科学基金会（NSF）资助项目编号OCE-1029316采集。其中CTD数据已完成重新处理、对齐校正，并剔除了异常值。营养盐样品在分析前采用GFF玻璃纤维滤膜进行过滤，并依照美-全球海洋通量联合研究（US-JGOFS）规程（http://usjgofs.whoi.edu/protocols_rpt_19.html）完成实验分析。所有数据均已确定为最终版本。
