Показано, что стандартный биооптический алгоритм OC4 существенно занижает спутниковые оценки концентрации хлорофилла-а (Хл-а) от ~1,5 до ~9 раз (в среднем в ~3,1 раза). Известный региональный алгоритм OC4-SO обеспечивает приемлемые ошибки оценки концентрации Хл-а и может быть использован для исследований, связанных с анализом концентрации Хл-а в водах вокруг Антарктического полуострова. Разработанный в данной работе новый региональный алгоритм OC4-AP имеет значительно меньшую ошибку по сравнению с известным стандартным и региональным алгоритмами. Он может быть использован в случае, если необходимо по лучить дистанционную оценку концентрации Хл-а, максимально приближенную к накопленному мировому опыту определения этой величины стандартными экстрактными спектрофотометрическим и флуориметрическим методами. Наблюдаемое занижение спутниковых оценок концентрации Хл-а по стандартному эмпирическому биооптическому алгоритму OC4 можно связать, как минимум, с тремя характерными для исследованной акватории причинами: малое относительное содержание ОРОВ, высокое содержание фикоэритрина и более сильный эффект упаковки пигментов в клетках фитопланктона по сравнению со средними значениями в Мировом океане.</p></abstract><trans-abstract xml:lang="en"><p>The features of the empirical bio-optical algorithm operation in the waters around the Antarctic Peninsula are analyzed based on a comparison of calibrated data from the shipborne flow fluorimeter and satellite data from the OLCI radiometer on Senti nel-3A and Sentinel-3B satellites during the Antarctic summers of January-February 2020 and 2022. It is shown that the standard OC4 bio-optical algorithm significantly underestimates satellite estimates of Chl-a concentration from ~1.5 to ~9 times (on aver age by a factor of ~3.1). The known regional OC4-SO algorithm provides acceptable errors of Chl-a concentration estimates and can be used for studies related to the analysis of Chl-a concentration in the waters around the Antarctic Peninsula. The developed in this work new regional algorithm OC4-AP has significantly lower error in comparison with the known standard and regional algorithms. It can be used if it is necessary to obtain a remote estimate of the concentration of Chl-a, as close as possible to the accumulated world experience in determining this value by standard extract spectrophotometric and fluorimetric methods. The observed underestimation of satellite estimates of Chl-a concentration using the standard empirical bio-optical OC4 algorithm can be attributed to at least three reasons typical for the studied water area: low relative CDOM content, high phycoerythrin content, and stronger effect of pigment packing in phytoplankton cells compared to the average values in the World Ocean.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эмпирический биооптический алгоритм</kwd><kwd>концентрация хлорофилла-а</kwd><kwd>коэффициент яркости моря</kwd><kwd>индекс цвета</kwd><kwd>показатель поглощения света</kwd><kwd>первичные гидрооптические характеристики</kwd><kwd>оптически-активные компоненты</kwd><kwd>атлантический сектор Южного океана</kwd><kwd>пролив Брансфилд</kwd><kwd>море Уэдделла</kwd></kwd-group><kwd-group xml:lang="en"><kwd>empirical bio-optical algorithm</kwd><kwd>chlorophyll-a concentration</kwd><kwd>remote-sensed reflectance</kwd><kwd>band ratio</kwd><kwd>light absorption coefficient</kwd><kwd>inherent optical properties</kwd><kwd>optically active components</kwd><kwd>Atlantic sector of the Southern Ocean</kwd><kwd>Bransfield Strait</kwd><kwd>Weddell Sea</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работы выполнены в рамках государственного задания ТОИ ДВО РАН № 124022100080-0 (создание биооптических алгоритмов и моделей) и № 124042300003–5 (разработка метода обработки данных проточного флуориметра); ИО РАН № FMWE-2024–0015 (адаптация метода ICAM, определение концентрации Хл-а); ИАПУ ДВО РАН № FWFW-2021–0001 (разработка проточного флуориметра); ИнБЮМ РАН № 124030100106-2 (получение первичных гидрооптических характеристик методом ICAM); МГИ РАН № FNNN-2024-0012 (получение судовых данных).</funding-statement><funding-statement xml:lang="en">The research was supported by the Ministry of Science and Higher Education of the Russian Federation: State tasks  of POI FEB RAS No. 124022100080-0 (development of bio-optical algorithms and models) and No. 124042300003-5  (development of the method for processing flow fluorimeter data), SIO RAS No. FMWE-2024-0015 (adaptation of  the ICAM method, determination of Chl-a concentrations), IACP FEB RAS No. FWFW-2021-0001 (development of  the flow fluorimeter), IBSS RAS No. 124030100106-2 (acquisition of inherent optical properties by ICAM method),   MHI RAS No. FNNN-2024-0012 (acquisition of ship data).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Churilova T., Moiseeva N., Skorokhod E. et al.
