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.

本数据集收录了南极光号（Aurora Australis）AA06/97航次（亦称SNARK航次）在15个观测站点采集的实测数据。研究人员沿东经142°附近的断面，于南纬42°至55°的海域内采集水样，以解析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，以及水体柱中溶解态（CDOM）、颗粒态（a/p）及碎屑态（a/d）组分的吸收系数。除站点水样外，研究人员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与类胡萝卜素色素开展分析。BSI六通道辐射计被部署于各观测站点。
