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.
