Special Issue Information

Dear Colleagues,

The carbon cycle has a profound impact on global climate change. The global warming and the increase of extreme weather phenomena caused by the continuous increase of greenhouse gas concentrations (e.g., carbon dioxide) in the atmosphere are attracting more and more attention. In order to deal with the problem of global warming caused by the continuous increase of atmospheric greenhouse gas concentrations, various countries around the world have signed a series of agreements on carbon emission reduction and carbon neutralization, among which the three most important agreements are the United Nations Framework Convention on Climate Change, the Kyoto Protocol and the Paris Agreement. At the same time, the research on the global carbon cycle, with carbon dioxide as the core, has been continuously strengthened and deepened.

Marine carbon cycle is an extremely important part of the global carbon cycle and is at the core of marine sciences. The study of carbon dynamics is crucial to understanding the marine carbon cycle. The dynamic processes of carbon in the ocean involves the dynamic change and mutual transformation of different forms and states of carbon, including their migration, transformation, degradation, burial and other complex biogeochemical processes of inorganic and organic carbon. From air–sea interface to sediments, from coastal waters to deep oceans, these processes are always in progress. Our understanding of the distribution and flux of organic and inorganic carbon in different forms and states is extensive and in-depth, but our understanding of their dynamic processes in marine environments still needs to be deepened and strengthened.

The aim of this Special Issue is to gather insightful contributions on carbon dynamics in coastal and deep ocean, including all aspects of the carbon cycle in marine environments. We hope to further understand how physical, chemical, biological, geological and other processes in the ocean dynamically affect the marine carbon cycle. We encourage researchers and practitioners from academia, industry, aquaculture etc. to submit their work and views so that a broad contribution can be delivered to the community on this hot and urgent topic.

You are cordially invited to contribute to this Special Issue.

The East Siberian Sea (ESS) is a large and the shallowest part of the Arctic Ocean. It is characterized by high biogeochemical activity, but the seawater carbonate system remains understudied, especially during the late autumn season. Data from the research vessel (RV) “Professor Multanovsky” cruise were used to assess the dynamics of the seawater carbonate system, air–sea CO2 fluxes, and the calcium carbonate corrosive waters in the two biogeochemical provinces of the ESS shortly before freeze-up. The ESS waters were mainly a sink for atmospheric CO2 due to the limited dispersion of river waters, autumn water cooling, and phytoplankton blooms in its eastern autotrophic province. The mean value of the CO2 air–sea flux was 11.2 mmol m−2 day−1. The rate of CO2 uptake in the eastern ESS was an order of magnitude larger than that in the western ESS. The specific waters and ice cover dynamics determined intensive photosynthesis processes identified on the eastern shelf and in the northern deep oligotrophic waters. A part of the surface and most of the bottom ESS waters were corrosive with respect to calcium carbonate, with the lowest saturation state of aragonite (0.22) in the bottom layer of the eastern ESS. The eastern ESS was the main source of these waters into the deep basin. The observed export of corrosive shelf waters to the deep sea can have a potential impact on the ocean water ecosystem in the case of mixing with layers inhabited by calcifying organisms.
