HLY-02-03 Particulate Organic Carbon (POC) and Particulate Nitrogen (PN) in sediments (ASCII). Version 1.0

This data set represents measurements of particulate organic carbon (POC) and particulate nitrogen (PN) for water column suspended particles collected during the 2002 U.S. Coast Guard Cutter (USCGC) Healy HLY-02-03 Process Cruise. Particulates were collected by filtration onto pre-combusted (450¡C for 4hrs) 25mm Whatman GF/F filters. The filters were stored frozen until analysis. Filters were dried at 40C for 24 hours, then carbonates were removed by vapor phase acidification with HCl. Samples were analyzed at the Nutrient Analytical Services Laboratory at the Chesapeake Biological Laboratory, University of Maryland Center for Environmental Science, Solomons, Maryland, using an Exeter Analytical, Inc., CE-440 Elemental Analyzer. These data are in ASCII format.

本数据集记录了2002年美国海岸警卫队希利号（USCGC Healy）HLY-02-03过程航次中采集的水体悬浮颗粒物的颗粒有机碳（POC）和颗粒氮（PN）测量数据。颗粒物通过过滤收集到预燃烧（450℃，4小时）的25mm Whatman GF/F滤膜上，滤膜冷冻保存直至分析。分析前，滤膜于40℃干燥24小时，随后通过HCl气相酸化去除碳酸盐。样本由马里兰州索罗门斯市马里兰大学环境科学中心切萨皮克生物实验室营养分析服务实验室使用埃克塞特分析公司（Exeter Analytical, Inc.）的CE-440元素分析仪进行检测。本数据集采用ASCII格式。
