Short summary
Short summary
Oceanic mesoscale eddies are known to form dipoles from time to time. When dipoles are asymmetric in strength, the stronger dipole eddies generally drive weaker ones to move around, resulting in a reduction of discrepancies in their kinematic properties, which is referred to as the “gear-like” process. An integrated observation of an asymmetric eddy dipole was conducted in the South China Sea in April 2023, which evidences the “gear-like” process.

This study examines how environmental factors, particularly temperature, affect the seasonal and spatial distribution of mesopelagic organisms in the North Atlantic. Using data from 720 BGC-Argo floats, we identified distinct daily and seasonal migration patterns. Temperature was the key driver, followed by salinity and dissolved oxygen. These findings enhance our understanding of mesopelagic ecosystems, with potential implications for fisheries management.

Mesoscale eddies are ubiquitous in the ocean and account for 90 % of its kinetic energy, but their generation and dissipation are difficult to observe using current remote sensing technology. Our submesoscale eddy dataset, formed by suppressing large-scale circulation signals and enhancing small-scale chlorophyll structures, has important implications for understanding marine environments and ecosystems, as well as improving climate model predictions.

High precision in reconstructing sea surface currents is vital for understanding ocean dynamics. Our paper introduces GEST (Geostrophic-Ekman-Stokes-Tide), a 15 m depth sea current product. GEST, generated by a neural network, captures Ekman, geostrophic currents, Stokes drift, and TPXO9 tidal currents. Its design accounts for complex ocean surface dynamics, surpassing OSCAR and GlobCurrent by 10.4 cm/s and 8.81 cm/s, respectively.

In this study, we mainly utilized BGC-Argo data to investigate the relationships between chlorophyll levels and environmental factors (CPhyto, Nitrate, Temperature and Light) and its underlying dynamic mechanisms of mesoscale eddies in South Pacific Ocean. We show that, the mechanism of chlorophyll levels are different at different depth of seawater.

Short summary
We present an accurate product of ocean surface current at 15 m depth based on multi-scale physical processes. Following a training process using remote sensing observations and in situ data, the derived current field with a 1/4° resolution captures more details neglected in the 1° ones and demonstrates higher accuracy over other global surface current products at low to middle latitudes.

Short summary
Black Hole Eddy (BHE) is vital for transporting materials but were previously hard to identify efficiently. This study introduces an efficient method to identify BHE, 13 times quicker, firstly enables the creation of BHE dataset in the North Pacific from 1993 to 2023. We verified BHE maintains strong coherence and contributes to westward transport about 1.5 Sv. We found some previously unidentified coherent eddies and analyzed their coherence. This represents first comprehensive analysis of BHE.
