Geophysical Research Letters, Volume 50, Issue 24, 28 December 2023., 2023 Abstract Most marine gas hydrate systems follow a vertical pattern with hydrate overlying free gas. Here we document the discovery of a gas to hydrate system in a horizontal sand layer in the Qiongdongnan Basin of the South China Sea. Eight wells were drilled by the Guangzhou Marine Geological Survey in 2021–2022 to investigate the occurrence and ...

Plant Biotechnology Journal, Volume 21, Issue 7, Page 1343-1360, July 2023., 2023 Summary FLOWERING LOCUS T (FT), a florigen in Arabidopsis, plays critical roles in floral transition. Among 13 FT‐like members in rice, OsFTL2 (Hd3a) and OsFTL3 (RFT1), two rice homologues of FT, have been well characterized to act as florigens to induce flowering under short‐day (SD) and long‐day (LD) conditions, respectively, but the functions of ...

Source Rock Evaluation of Hydrocarbons in Deep‐Water Offshore Areas Based on a BP Neural Network
Geofluids, Volume 2023, Issue 1, 2023., 2023 Due to the lack of drilling data and poor quality of seismic data in deep‐water offshore areas, conventional methods cannot effectively predict the total organic carbon (TOC) content. In this paper, the BP neural network method is used to predict the TOC of the strata overlying the target layer, which adds to the TOC information in the study area. Then,
