BEAGLE 2003, Leg 2, Papeete (Tahiti) to Valparaiso (Chile), HPLC Pigment and Ocean Colour Data

The Japan Agency for Marine-Earth Sciences and Technology (JAMSTEC) sponsored this research cruise - a circumnavigation of the Southern hemisphere using the World Ocean Circulation Experiment (WOCE) Hydrographic Program (WHP) lines in the southern hemisphere to celebrate the 30th anniversary of its establishment. The research cruise was named "BEAGLE 2003" (Blue EArth GLobal Expedition 2003) and was carried out on the RV MIRAI. This is a subset of the Beagle 2003 data set and contains the HPLC pigment and particulate absorption coefficient data collected on leg 2, between Papeete, Tahiti and Valparaiso, Chile from the 12 Sept to 11 Oct 2003. The data can be used for Ocean Colour sensor validation. Parameters measured on the leg are the concentration of chlorophyll and carotenoid pigments and the absorption coefficent for particulate (a/p) components of the water column. Samples were collected at 40 stations. The data was used primarily to validate ocean colour sensors MERIS, MODIS and SeaWIFs and the SST sensor AATSR. Samples were collected and analysed for pigments and absorption coefficient, particulate.

日本海洋地球科学技术厅（Japan Agency for Marine-Earth Sciences and Technology, JAMSTEC）为纪念其成立30周年，资助了本次南半球环球科考航次——依托南半球的世界大洋环流实验（World Ocean Circulation Experiment, WOCE）水文计划（Hydrographic Program, WHP）断面开展作业。本次航次命名为“BEAGLE 2003”（全球蓝色地球考察2003），由“未来号”（RV MIRAI）科考船执行任务。
本数据集为BEAGLE 2003航次的子集，包含2003年9月12日至10月11日期间，在塔希提岛帕皮提至智利瓦尔帕莱索的第2航段采集的高效液相色谱（High Performance Liquid Chromatography, HPLC）色素数据与颗粒物吸收系数数据。
该数据集可用于海洋水色传感器验证。本航段测定的参数包括水体柱体颗粒物（a/p）组分的叶绿素、类胡萝卜素浓度，以及其吸收系数。本次航次共在40个站位采集样本。
本数据主要用于验证海洋水色传感器MERIS、MODIS、SeaWIFs以及海表温度传感器AATSR。所有与色素、吸收系数及颗粒物相关的样本均已完成采集与分析。
