AbstractThis study examines long-term ocean pH data to evaluate ocean acidification (OA) trends at two coastal research institutions located on the Sea of Japan and the Pacific Ocean. These laboratories are located away from the influences of large rivers and major industrial activity. Measurements were performed daily for the past 30 years (1980s–2010s). The average annual ocean pH for both sites showed generally negative trends. These trends were – 0.0032 and – 0.0068 year–1 (p < 0.001) at the Sea of Japan and Pacific Ocean sites, respectively. The trends were superimposed onto approximately 10-year oscillations, which appear to synchronize with the ocean current periodicity. At the Sea of Japan site, the ocean pH in the summer was higher, and the rate of OA was higher than during other seasons. Our results suggest that seasonality and ocean currents influence OA in the coastal areas of open oceans and can affect the coastal regions of marginal seas.

Констатируется, что континентальное обрамление и окраинные моря Тихого океана как планетарная ландшафтная геосистема в освоении Мирового океана и выделенные как Тихоокеанский ландшафтный пояс (https://doi.org/10.18411/a-2017-089) как основа - модель научного и практического освоения геосистемы океан- континент ранее не рассматривалась. В настоящее время в связи с освоением переходной зоны Азиатского континента к океану появилась необходимость рассмотреть возможности применения ландшафтного подхода в практиках освоения геосистем этой зоны. Работа, представляет собой продолжение комплексных исследований в целом сформировавшейся ландшафтной школы профессора В.Т. Старожилова (doi:10.24411/1728-323Х-2020-13079, doi:10.18411/lj-05-2020-26). Отмечается, что комплексное изучение ландшафтной структуры обрамления Тихого океана, имеет базовое значение при природопользовании Мирового океана. Именно ландшафтный пояс, включающий Сихотэ-Алинскую, Нижнеамурскую, Камчатско-Курильскую, Сахалинскую и другие ландшафтные области и сопряженные с ними окраинные моря, представляет собой часть единой с Тихим океаном структуры природы и представляются как основа для выполнения задач науки и практики освоения территорий континентального обрамления Тихого океана, окраинных морей и использования материалов в освоении Мирового океана. Он, как планетарная ландшафтная структура, является базовой моделью «фундаментом» для построения гармонизированных с природой и связанных с океаном экологических, сельскохозяйственных и других отраслевых моделей освоения этой обширной тихоокеанской зоны. Отмечается, что в свою очередь применение компьютерной технологии векторно-слоевого ландшафтного метода создают платформу для разработки планов и проектов освоения. Он также является платформой для обучения студентов. Приводятся данные о картографической обеспеченности пояса современными векторно-слоевыми цифровыми материалами. It is stated that the continental framing and marginal seas of the Pacific Ocean as a planetary landscape geosystem in the development of the World Ocean and identified as the Pacific landscape belt (https://doi.org/10.18411/a-2017-089) as a basis - a model of scientific and practical development of the geosystem ocean-continent has not been previously considered. Currently, in connection with the development of the transition zone of the Asian continent to the ocean, it is necessary to consider the possibilities of applying the landscape approach in the practice of developing the geosystems of this zone. The work is a continuation of the comprehensive studies of the generally formed landscape school of Professor V.T. Starozhilov (doi: 10.24411 / 1728-323X-2020-13079, doi: 10.18411 / lj-05-2020-26). It is noted that a comprehensive study of the landscape structure of the Pacific Ocean framing is of fundamental importance in the use of natural resources in the World Ocean. It is the landscape belt, including the Sikhote-Alin, Nizhneamur, Kamchatka-Kuril, Sakhalin and other landscape areas and the marginal seas associated with them, that is a part of the structure of nature united with the Pacific Ocean and is presented as the basis for fulfilling the tasks of science and practice of developing territories of the continental framing The Pacific Ocean, marginal seas and the use of materials in the development of the World Ocean. It, as a planetary landscape structure, is the basic model "foundation" for building harmonized with nature and related to the ocean ecological, agricultural and other sectoral models for the development of this vast Pacific zone. It is noted that, in turn, the use of computer technology of the vector-layer landscape method creates a platform for the development of plans and development projects. It is also a platform for student learning. The data on the cartographic provision of the belt with modern vector-layer digital materials are presented.
