Gulong shale oil in the first member of the Qingshankou Formation, Songliao Basin, has considerable exploration potential, yet the evolution of its reservoir remains poorly constrained. Clarifying this evolution is essential for evaluating reservoir properties and identifying prospective intervals. In this study, Gulong shale core samples from the first member of the Qingshankou Formation were collected from multiple wells acr...

Humans have long been fascinated by the mysteries surrounding fish migrations and addressing these complex behaviors often requires large data sets. Biogeochemical tags, including trace elements and stable isotopes, are the most accessible biomarkers for tracking fish migrations. However, access to standardized biogeochemical tag data is rarely available for migratory fish, which limits our understanding of the evolutionary or...

Underwater target detection is a crucial aspect of ocean exploration. However, conventional underwater target detection methods face several challenges such as inaccurate feature extraction, slow detection speed, and lack of robustness in complex underwater environments. To address these limitations, this study proposes an improved YOLOv7 network (YOLOv7-AC) for underwater target detection. The proposed network utilizes an ACm...
