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）赞助了本次环南半球科考航次：为庆祝其成立30周年，本次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）断面开展航行。本次科考航次命名为“BEAGLE 2003”（Blue EArth GLobal Expedition 2003，即全球蓝色地球考察2003），由科考船RV MIRAI执行。本数据集为BEAGLE 2003科考数据集的子集，涵盖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）色素与颗粒吸收系数数据。该数据可用于海洋色传感器的性能验证。本航段测定的参数包括叶绿素与类胡萝卜素色素浓度，以及水柱颗粒组分的吸收系数（a/p）。科考团队共在33个站位完成样品采集。本数据集主要用于验证海洋色传感器MERIS、MODIS、SeaWiFS以及海表温度传感器AATSR。
