Open AccessDiel vertical migration promotes zooplankton horizontal patchiness
Spatial patchiness of plankton enhances fishery production and carbon export in the ocean. While diel vertical migration (DVM) has been identified as an important factor contributing to vertical patchiness, it...

Open AccessMicro-scale patchiness enhances trophic transfer efficiency and potential plankton biodiversity
Rather than spatial means of biomass, observed overlap in the intermittent spatial distributions of aquatic predators and prey is known to be more important for determining the flow of nutrients and energy up ...

Open AccessTurbulence mediates marine aggregate formation and destruction in the upper ocean
Marine aggregates formed through particle coagulation, large ones (>0.05 cm) also called marine snow, make a significant contribution to the global carbon flux by sinking from the euphotic zone, impacting the ...

Hypolimnetic turbulence generation associated with superposition of large-scale internal waves in a strongly stratified lake: Lake Biwa, Japan
A 48-h microstructure experiment captured the variation of turbulence in Lake Biwa, Japan, during a strong stratification period, 1 week after a typhoon event. A free-fall microstructure profiler (TurboMAP) an...

Multilayer biological structure and mixing in the upper water column of Lake Biwa during summer 2008
We carried out a 24-h station experiment at Lake Biwa (Japan) to measure mixing events and concurrent biological signals using a free-fall microstructure profiler (TurboMAP-L), conventional hydrographic measur...

Oceanic Velocity Microstructure Measurements in the 20th Century
The science of ocean turbulence was started more than 50 years ago by a small research group using a surplus mine-swee** paravane to measure the velocity and temperature fluctuations in the ocean. The field ...

Observations of a Kelvin-Helmholtz Billow in the Ocean
We identified a Kelvin-Helmholtz billow from vertical turbulence velocity and instantaneous heat flux signals obtained from airfoil shear probes and thermistors mounted on a research submarine. The vertical tu...

An Application of Turbulence Data to the California Undercurrent
Persistent and large rates of the dissipation of kinetic energy were observed in the intrusive region of the California Undercurrent. Viscous dissipation can extract the total mechanical energy (potential plus...
