South China Sea records Late Miocene reorganization of western Pacific deep circulation.

Oceanic gateways play a crucial role in controlling global ocean circulation. However, gateway effects on low-latitude deep-water circulation are poorly understood. The South China Sea, located in the western Pacific, was influenced by changes in the equatorial and low-latitude gateways, which recorded significant oceanographic variations since the Oligocene.

Microbial Diversity, Community Turnover, and Putative Functions in Submarine Canyon Sediments under the Action of Sedimentary Geology.

Sampling challenges in deep-sea ecosystems lead to a lack of knowledge about the distribution of microbes in different submarine canyons. To study microbial diversity and community turnover under different ecological processes, we performed 16S/18S rRNA gene amplicon sequencing for sediment samples from a submarine canyon in the South China Sea. Bacteria, archaea, and eukaryotes made up 57.

Bacterial, archaeal, and fungal community structure and interrelationships of deep-sea shrimp intestine and the surrounding sediment.

Invertebrate shrimp are one of the dominant benthic macrofaunae in the deep-sea environment. The microbiota of shrimp intestine can contribute to the adaptation of their host. The impact of surrounding sediment on intestinal microbiota has been observed in cultured shrimp species, but needs to be further investigated in deep-sea shrimp.
