Equatorial Indian Ocean productivity over the last 200,000 years and links to deep circulation variations

Ocean circulation plays a key role in regulating atmospheric carbon dioxide levels during Pleistocene glacial-interglacial cycles. However, spatial responses of the oceans remain poorly constrained because reliable records from important carbon exchange regions, such as the equat...

Intraseasonal variability and eddy-induced structural modulation of the North Pacific intermediate water revealed by multi-mooring observations

Abstract. The North Pacific Intermediate Water (NPIW) plays a crucial role in modulating oceanic thermohaline circulation and biogeochemical processes. However, limited continuous observations have hindered the understanding of its short-term variability and structural response t...

A Novel n-Hexadecane-Degrading Bacterium Provisionally Named “Thermalkanevorax longiformis” Isolated from a Deep-Sea Hydrothermal Vent

Hydrothermal systems contain diverse alkanes derived from biological and geological processes, providing potential carbon and energy sources for microorganisms. However, cultivated thermophilic alkane-utilizing bacteria from hydrothermal environments remain poorly characterized....

Temperature-DrivenInterconversion of Shale Oil

Abstract Understanding the occurrence state and thermal mobilization mechanism of shale oil is essential for improving recovery efficiency from nanoporous shale reservoirs. In this study, a series of thermal volatilization experiments (40–80 °C) combined with NMR (T2 and T1-T2) w...

Super-resolution downscaling of WRF-based typhoon wind fields over complex coastlines using a decoupled physics-guided U-Net

Accurate kilometer-scale typhoon wind fields are important for coastal hazard assessment, but Weather Research and Forecasting (WRF)-based dynamical downscaling remains computationally expensive, while traditional statistical methods often fail to capture localized topographic ef...

A conserved miR-7132a/SOCS1/STAT2 regulatory axis enhances type I IFN antiviral responses in teleost fish

Type I interferon (IFN) signaling plays an essential role in restricting viral infection. Accumulating evidence indicates that microRNAs (miRNAs) serve as key regulators of the type I IFN signaling in mammals. However, whether the miRNA-mediated regulation is involved in type I I...

Antarctic Circumpolar Current creates a boundary limiting the meridional dispersal of bacteria in the Southern Ocean

Impact statement As the world's largest ocean current in terms of volume transport, the Antarctic Circumpolar Current (ACC) significantly affects the movement of heat and water in the Southern Ocean. However, the impact of the ACC on the biogeographic distribution of marine bacte...

Multi-omics and cultivation reveal laminarin-degrading PVC bacteria in the deep sea

The deep sea is home to a vast and largely unexplored microbial biosphere, along with large amounts of complex organic matter (COM). However, the functional capacity of the deep-sea microbiome to metabolize organic matter across diverse regions remains poorly understood. Here, we...
