 DeepSea MOT consists of 4 video sequences (2 midwater, 2 benthic) with a total of 2,400 frames and 57,376 annotated objects comprising 188 tracks. The videos were captured by the [Monterey Bay Aquarium Research Institute (MBARI)](https://www.mbari.org/) using remotely operated vehicles (ROVs) [*Doc Ricketts*](https://www.mbari.org/technology/rov-doc-ricketts/) and [*Ventana*](https://www.mbari.org/technology/rov-ventana/) in deep-sea environments, showcasing a variety of marine species and underwater scenes.
 
+**[2025-12-08] New 4K Sequences:** In addition to the original sequences, DeepSea MOT now includes two new 4K resolution sequences (Benthic Simple and Midwater Simple) to facilitate research on high-resolution underwater video analysis.
