A bio-optical model for the Barents Sea is determined from a set of in situ observations of inherent optical properties (IOPs) and associated biogeochemical analyses. The bio-optical model provides a pathway to convert commonly measured parameters from glider-borne sensors (CTD, optical triplet sensor—chlorophyll and CDOM fluorescence, backscattering coefficients) to bulk spectral IOPs (absorption, attenuation and backscattering). IOPs derived from glider observations are subsequently used to estimate remote sensing reflectance spectra that compare well with coincident satellite observations, providing independent validation of the general applicability of the bio-optical model. Various challenges in the generation of a robust bio-optical model involving dealing with partial and limited quantity datasets and the interpretation of data from the optical triplet sensor are discussed. Establishing this quantitative link between glider-borne and satellite-borne data sources is an important step in integrating these data streams and has wide applicability for current and future integrated autonomous observation systems. This article is part of the theme issue ‘The changing Arctic Ocean: consequences for biological communities, biogeochemical processes and ecosystem functioning’.

开发巴伦支海生物光学模型，以定量连接滑翔机和卫星观测

巴伦支海的生物光学模型是根据一组对固有光学特性 (IOP) 和相关生物地球化学分析的原位观测确定的。生物光学模型提供了一种将滑翔机传感器（CTD、光学三重传感器——叶绿素和 CDOM 荧光、背向散射系数）的常用测量参数转换为体光谱 IOP（吸收、衰减和背向散射）的途径。随后使用从滑翔机观测中获得的 IOP 来估计遥感反射光谱，与同步卫星观测进行比较，为生物光学模型的普遍适用性提供独立验证。讨论了生成稳健的生物光学模型的各种挑战，包括处理部分和有限数量的数据集以及对来自光学三重传感器的数据的解释。在滑翔机和星载数据源之间建立这种定量联系是整合这些数据流的重要一步，对当前和未来的综合自主观测系统具有广泛的适用性。本文是主题问题“不断变化的北冰洋：对生物群落、生物地球化学过程和生态系统功能的影响”的一部分。在滑翔机和星载数据源之间建立这种定量联系是整合这些数据流的重要一步，对当前和未来的综合自主观测系统具有广泛的适用性。本文是主题问题“不断变化的北冰洋：对生物群落、生物地球化学过程和生态系统功能的影响”的一部分。在滑翔机和星载数据源之间建立这种定量联系是整合这些数据流的重要一步，对当前和未来的综合自主观测系统具有广泛的适用性。本文是主题问题“不断变化的北冰洋：对生物群落、生物地球化学过程和生态系统功能的影响”的一部分。
