A hybrid underwater robot for multidisciplinary investigation of the ocean twilight zone

Science Robotics, 2021
We present the design and at-sea results from a hybrid marine robot called Mesobot that can actively track midwater phenomena. Mesobot, an autonomous underwater vehicle, addresses specific unmet needs for observing and sampling a variety of phenomena in ...

Elephant seals as ecosystem sentinels for the northeast Pacific Ocean twilight zone.

Science
The open ocean twilight zone holds most of the global fish biomass but is poorly understood owing to difficulties of measuring subsurface ecosystem processes at scale.

Primary production drives varied zooplankton migration strength and twilight‐zone particle dynamics across ecological gradients in the western North Pacific

Limnology and Oceanography
Diel vertical migrations (DVM) of zooplankton play a crucial role in transferring organic matter efficiently to the deep ocean. However, the spatial regulatory determinants of DVM strength, including migrant biomass and migration amplitude, remain ...

The twilight zone

New Scientist, 2009
Consciousness is a strange beast. Most of the time you're either awake or asleep, yet these are far from the only states our minds can enter. Over the next 10 pages we explore some of these journeys of the mind, from hypnosis to sleep paralysis. Some of them may seem scary and exotic, but most of us experience at least one at some point in our lives ...

Physicochemical Evaluation of Remote Homology in the Twilight Zone

Proteins: Structure, Function, and Bioinformatics
A fundamental problem in the field of protein evolutionary biology is determining the degree and nature of evolutionary relatedness among homologous proteins that have diverged to a point where they share less than 30% amino acid identity yet retain ...
