Abstract

The polar oceans, including the Southern Ocean and the Arctic Ocean, are key players in global ocean circulation, climate change, as well as marine ecosystems. The year of 2024 marks the 40th anniversary of Chinese National Antarctica and Arctic Research Expedition (CHINARE), which has completed 41 Antarctic and 14 Arctic Ocean expeditions so far, with oceanographic surveys mainly focused on the Prydz Bay, Ross Sea and Amundsen Sea around the Antarctica, and also on the western and central Arctic Ocean. CHINARE has made significant progress in capacity building, ocean observation and scientific research to understand the polar oceans and their global impact, contributing considerably to international programs such as SOOS, PPP, MOSAiC, DAMOCLES and DBO. Here we review some of these progress and contributions, mostly from the perspective of physical oceanography, and briefly outline our future plans and research priorities in the years to come. China is surely in the process of largely enhancing its polar research activities, which will provide support and new opportunities for international collaboration in this important research area, especially with our European colleagues.

BCCR Monday Seminar 8th September: " Wave-driven ocean currents: how ocean responds to Stokes transport"

This BCCR Monday Seminar will be given by Yasushi Fujiwara from Kobe University. He will present his work on " Wave-driven ocean currents: how ocean responds to Stokes transport". Abstract Stokes drift associated with surface waves induces mass transport that interacts with ocean currents. Its effects can be represented in governing equations as external forcings such as Coriolis-Stokes and vortex forces. While pointwise current responses (anti-Stokes Eulerian current) have long been studied, nonlocal responses to spatially varying waves remain less understood. Here, using linearized wave-averaged theory, we show that inhomogeneous Stokes transport induces horizontal convergence/divergence, driving nonlocal geostrophic responses via effective Ekman pumping. Idealized simulations reveal dipole circulation around localized Stokes forcing, and over sloping topography, transient forcing excites topographic Rossby waves that irreversibly modify geostrophic currents. A simulation with realistic topography and wave forcing shows Lagrangian transport of O(1) m^2/s persisting for days after a cyclone. About the speaker Yasushi Fujiwara is an Assistant Professor at Kobe University, Japan. He received his Ph.D. in Physical Oceanography from Kyoto University, Japan. His research focuses on small-scale processes in the oceanic boundary layer, particularly wave–current interactions, surface wave dynamics, wind–wave coupling, and their representation in numerical models. He primarily investigates these problems using numerical approaches, notably through a wave-phase-resolved model that explicitly simulates the interaction between turbulence and wave motions.

"Abrupt CO₂ uptake and ecosystem responses in the Subpolar North Atlantic under global warming".

Name of speaker: Huiji Lee from Seoul National University, South Korea. Abstract The ocean is a crucial sink for anthropogenic CO2 emissions, yet its future response remains uncertain. Here, using the Community Earth System Model (CESM2) under different CO2 emission rates, we find a pronounced weakening of ocean CO2 uptake in the Subpolar North Atlantic (SPNA), distinct from the global response. Initially, the SPNA is an effective CO2 sink, but due to the contraction of deep convection, the uptake decreases and the oceanic pCO2 exceeds the global average. Recognizing the importance of regional ocean circulation in CO2 uptake, we identify a nonlinear relationship between environmental conditions and uptake response, revealing consistent thresholds for the emergence of uptake weakening. Overall, the distinct uptake response reflects the key role of regional dynamics in regulating the CO2 budget and geochemical environment, and such abrupt change in the regional carbon cycle may ultimately trigger severe ecosystem disruptions. This highlights the importance of accounting for regional dynamics in future CO2 mitigation strategies. About the speaker I am currently a PhD student at the Seoul National University, South Korea, and a visiting researcher at NORCE/Bjerknes Centre for six months. My research interests focus on the ocean carbon cycle and marine ecosystems, with particularly how ocean buffering capacity regulates climate projections and the potential of ocean-based carbon dioxide removal strategies.
