BEAGLE 2003, Leg 4, Santos (Brazil) to Cape Town (South Africa) 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 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 4, between Santos, Brazil and Cape Town, South Africa from the 7 Nov to 1 Dec 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 33 stations. The data was used primarily to validate ocean colour sensors MERIS, MODIS and SeaWIFs and the SST sensor AATSR.

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——依托南半球的世界海洋环流实验（World Ocean Circulation Experiment, WOCE）水文计划（Hydrographic Program, WHP）航线开展作业。本次航次命名为“BEAGLE 2003（蓝色地球全球考察2003）”，搭载平台为“未来号”（RV MIRAI）科考船。本数据集为BEAGLE 2003数据集的子集，包含2003年11月7日至12月1日期间，在巴西桑托斯至南非开普敦的第4航段采集的高效液相色谱（High Performance Liquid Chromatography, HPLC）色素与颗粒物吸收系数数据。该数据可用于海洋水色传感器的验证工作。本航段测量的参数包括水体柱内叶绿素与类胡萝卜素色素浓度，以及水体颗粒物组分的吸收系数（a/p）。本次科考共在33个站位完成样本采集。本数据集主要用于验证海洋水色传感器MERIS、MODIS及SeaWiFS，以及海表温度传感器AATSR。
