Size-fractionated optical backscattering and chlorophyll fluorescence from 34 high-latitude phytoplankton blooms

this dataset contains bin-averaged optical particle measurements from biogeochemical argo floats. full description of data and methodology is contained in the manuscript submitted to science entitled "particle fragmentation exerts strong control on biological sequestration of co2 by the oceans". optical measurements are particulate backscattering and chlorophyll fluorescence, and each have been partitioned into large (>100 µm) and small (<100 µm) size classes for use in estimating the rate of fragmentation of large, sinking partiles. the data cover 34 high-latitude open-ocean mesopelagic sinking particle plumes in the supolar north atlantic and the southern ocean observed at 1 m vertical resolution and 2-5 day temporal resolution by profiling floats over a 30-day period. each 30-day period is divided into five temporal bins of six days each. vertical binning is at 50-meter intervals from the 250-950 m.

本数据集收录了生物地球化学型 Argo 浮标所进行的二进制平均光学粒子测量数据。数据与方法的全部分析内容包含于提交至《科学》杂志的论文《粒子破碎对海洋生物对二氧化碳的封存作用的强烈控制》。光学测量包括颗粒后向散射和叶绿素荧光，两者均被划分为大尺寸（>100 µm）和小尺寸（<100 µm）两类，以便用于估算大型沉降粒子的破碎速率。数据涵盖了34个高纬度开阔海洋中上层沉降粒子羽流，位于极北大西洋和南大洋，其观测以1米的垂直分辨率和2-5天的时序分辨率，通过30天期间的浮标剖面观测完成。每个30天的周期被划分为五个6天的时间段。垂直分层间隔为250-950米范围内的50米间隔。
