Summary: Recent reports show the presence of active cold seep sites associated with shallow gas hydrates off the east coast of India. Sampling of benthic fauna revealed different food sources and trophic structures among species. Isotope analysis of the soft tissues provided insights into the potential food sources and trophic interactions within the ecosystem.

Summary: By studying the microbial community structure in different tissues of Bathymodiolus platifrons and B. japonicus from cold seeps and hydrothermal vents, it was found that symbiotic bacteria in the gill were particularly significant. The community structures of the two mussel species from the same habitat were similar, while structural variations were observed in adductor muscle, mantle, foot, and visceral mass between different environments.

Summary: This study investigates submarine gas hydrate deposits from different regions of the world's oceans using isotope analysis, providing insights into the source and generation depth of methane. The findings suggest that the isotopic composition of methane can provide information about microbial and thermogenic sources, and the apparent temperature can be used to infer the depth of methane generation.

Summary: This paper introduces an easy-to-operate underwater Raman system with a compact design and competitive sensitivity, which was proven successful through a sea trial with over 20,000 spectra captured from various underwater targets. The system has the potential to be developed into a universal deep-sea survey and detection equipment in the future.

Summary: This article introduces a ship-borne cold seep sonar system that detects the existence of submarine cold seep by measuring scattering intensity and displays it through an intuitive acoustic image. Through investigation and measurement in the South China Sea, it is proven that the system can effectively identify submarine cold seep.

Summary: The new species of deep-sea neolepadid stalked barnacle, Vulcanolepas verenaesp. nov., described in this study shows distinct morphological characteristics and exhibits plasticity in its external morphology. The first report of the genus Vulcanolepas in the northern hemisphere raises questions about the phylogeography of Neolepadidae, and the relationship between key morphological characteristics and feeding habits in the family is discussed, with a focus on the specialized culturing of filamentous bacteria by Vulcanolepas species.

Summary: This study introduces a new metric, haplotype network branch diversity (HBd), which quantifiably compares haplotype network complexity by combining genetic and topological diversity. Results demonstrate that HBd can provide straightforward comparisons of network complexity and distinguish situations that are difficult to resolve with other available metrics.

Summary: This paper investigates the influence of concentration, vent size, and vent burst pressure on the vented ethylene-air explosion through numerical simulation and experiments. The different phases of external flame propagation are concluded by comparing experimental photos and simulation results. The mechanism of external flame propagation is analyzed using flow velocity, velocity vector, and turbulence kinetic energy.

Summary: This study investigated the taxonomic composition, functions, and potential interactions of symbionts in deep-sea invertebrates. The results revealed metabolic interactions among different symbionts, which contribute to the overall adaptability of the community. Additionally, elemental sulfur was found to enhance sulfur utilization in the community. These findings highlight the importance of microbe-microbe interactions in symbiosis and deep-sea adaptation.

Summary: Two new and six known dixiamycins were isolated from the culture broth of a cold-seep-derived actinomycete Streptomyces olivaceus OUCLQ19-3. The compounds showed notable growth inhibitions against multi-drug-resistant strains, with some being more potent than the positive control tetracycline. Extensive spectroscopic analyses were used to elucidate the structures of the compounds.

Summary: This study examines the transmission dynamics of HIV-1 subtype B across the San Diego and Tijuana border region, revealing the importance of local transmission in sustaining the epidemic. Geospatial factors and HIV risk groups contribute differently to the local dynamics. While focus on central San Diego may prevent most spread, county-wide efforts will be more effective due to substantial viral migration independent of central San Diego.

Summary: The study suggests that carbonate rocks in marine methane seeps host methane-oxidizing microbial communities with substantial methanotrophic potential. Laboratory experiments showed that carbonates from Point Dume seep off the coast of Southern California exhibited the highest rates of anaerobic methane oxidation measured so far. The research highlights the importance of rock-hosted methanotrophy as a significant contributor to marine methane consumption.

Summary: Marine hydrocarbon seeps, which release significant amounts of greenhouse gases and hydrocarbons into the atmosphere and hydrosphere, are usually studied using seafloor observations. However, the variability of seepage rates and locations leads to uncertainty. In this study, marine electromagnetic methods were used to investigate the deeper sources and accumulation sites of hydrocarbons. The results indicate that the method is sensitive to the structure of shallowly buried marine hydrocarbon seeps and can efficiently identify and characterize them. The findings also reveal spatial variability of seafloor hydrocarbons and previously unidentified intermediate depth accumulation sites.
