Woods Hole Oceanographic Institution and partners discover new ocean predator in the Atacama Trench
Characterized by darkness and intense pressure, the oceanโs hadal zone seems uninhabitable, yet dozens of unique organisms call it home. Each species discovered there adds a crucial piece to the puzzle of how life has evolved and even thrives in one of Earth's most extreme environments.
A new study published in Systematics and Biodiversity highlights one of those species - the newly named Dulcibella camanchaca. This crustacean is the first large, active predatory amphipod from these extreme depths. The species was discovered by scientists from Woods Hole Oceanographic Institution (WHOI) and Instituto Milenio de Oceanografรญa (IMO) based at the Universidad de Concepciรณn, Chile.

The trenches that are the deepest part of the ocean are an important sink for organic matter. But how that organic matter gets there, and where it comes from, have been mysterious. A study in Journal of Geophysical Research - Biogeosciences provides new insights in the cycling of carbon between the upper and deep ocean:

Samples From Deep Ocean Trench Contain Alarming Levels of Industrial Chemicals
PCBs were banned worldwide in the 1980s, but they're showing up in remote parts of the ocean.
