Southern Ocean Chlorophyll-a, pigment and optical data from Aurora Australis AA 1997/98 V6

This record contains data collected at 15 stations on the Aurora Australis AA06/97 cruise, known as the SNARK cruise. Water samples were generally collected along a transect around 142degE from 42-55degS to determine the bio-optical characteristics of the region. Parameters measured are the concentration of chlorophyll and carotenoid pigments and the absorption coefficient for dissolved (CDOM) particulate (a/p) and detrital (a/d) components of the water column. In addition to the station samples 106 water samples were collected from the output of the underway fluorometer and analysed for chlorophyll and carotenoid pigments only. The BSI six-channel radiometer was deployed ot station.

本数据集收录了别称SNARK航次的南极光号（Aurora Australis）AA06/97科考航次中，于15个站位采集的观测数据。研究人员沿约东经142°、南纬42°至55°的断面采集水样，以探究该区域的生物光学特性。本次测量的参数涵盖叶绿素与类胡萝卜素色素浓度，以及水柱中有色可溶性有机物（CDOM）、颗粒物（a/p）和碎屑（a/d）组分的吸收系数。除站位水样外，科研团队还从走航式荧光计的输出端采集了106份水样，仅针对其中的叶绿素和类胡萝卜素色素进行分析。BSI六通道辐射计被部署至各站位开展观测。
