Optical density (median) by non-algal particles during POLARSTERN cruise PS99@en

Absorption coefficients (abs) and optical density (OD) by total particles, phytoplankton and non-algal particles (NAP) were measured with standard deviation (sd) estimated on water samples collected from underway AC-S flow-through system outflow and CTD. Measurements were performed using QFT-ICAM (Röttgers et al., 2016) as described in Liu et al. (2018) and Liu et al. (2019). […]针对总颗粒物、浮游植物及非藻类颗粒物（non-algal particles，NAP）的吸收系数（absorption coefficients，缩写abs）与光密度（optical density，缩写OD）开展了测量，相关参数的标准差（standard deviation，缩写sd）基于走航AC-S流通系统出水口及温盐深仪（Conductivity Temperature Depth，CTD）采集的水样进行估算。测量操作采用QFT-ICAM完成，该方法由Röttgers等（2016）提出，具体细节详见Liu等（2018）及Liu等（2019）的文献描述。[…]
