TL;DR: In this article, the authors report plastic pollution in the deep-sea based on the information from a recently developed database, which archives photographs and videos of debris that have been collected since 1983 by deep sea submersibles and remotely operated vehicles.

TL;DR: A new whale-bone-eating polychaete species of the genus Osedax was found on sperm whale carcasses submerged off Cape Nomamisaki, Kyushu, Japan, at a depth of approximately 200 m and is the first species from the western Pacific.

TL;DR: Benthic communities were similar across all the carcasses studied, although the body sizes of the whales were very different, and the succession of epifaunal communities was relatively rapid and the sulphophilic stage was considerably shorter than that of other known whale falls.

TL;DR: It is argued that diatom blooms observed by remote sensing facilitated rapid deposition of 134Cs to hadal environment and the aftershocks induced successive sediment disturbances and maintained dense nepheloid layers in the trench even four months after the mainshock.

TL;DR: A dense community of benthic animals was discovered by the Japanese ROV 'Kaiko' in the hadal zone near the bottom of the Japan Trench, 7326 m deep, dominated by a new species of thyasirid bivalve Maorithyas hadalis.
