%X The methodologies employed for the identification of coherent ocean eddies can be categorized as either Eulerian or Lagrangian. Among Lagrangian structures, Black Hole Eddies exhibit the highest degree of material coherence and conservation, making them particularly suitable for studies on the transport and retention of oceanic materials. Using an efficient  Graphics Processing Unit (GPU)-based Black Hole Eddy identification and tracking algorithm, the first North Pacific Black Hole Eddy dataset was constructed for the first time based on satellite-derived surface geostrophic velocity data spanning January 1, 1993 to May 5, 2023. This dataset contains not only the general features (eddy center position, equivalent radius, eddy area, etc.) of eddies with lifetimes of T=30-day and 90-day but also the trajectories of Black Hole Eddy over the lifetime. This research addresses the existing gap in Black Hole Eddy datasets within the field of oceanography and offers additional insights for oceanographers who seek to comprehend the interactions between coherent eddies and oceanic physical phenomena.
