Influence of atomic mixing and preferential sputtering on depth profiles and interfaces [PDF]

open access: yes, 1979
Atomic mixing and preferential sputtering impose a depth resolution limit on the use of sputter sectioning to measure the composition of metal–semiconductor interfaces.

Parameters for the depth of the ocean’s productive layer

open access: yesFrontiers in Marine Science, 2023
Here we compare various parameters that are used to define the depth of the ocean’s productive layer, the euphotic zone, during the initiation of the spring phytoplankton bloom in the North Atlantic (47°N/20°W).

Impact of ocean vertical-mixing parameterization on Arctic sea ice and upper-ocean properties using the NEMO-SI3 model [PDF]

open access: yesGeoscientific Model Development
We evaluate the vertical turbulent-kinetic-energy (TKE) mixing scheme of the NEMO-SI3 ocean–sea-ice model in sea-ice-covered regions of the Arctic Ocean.

Radar Reflectivity–Based Estimates of Mixed Layer Depth

open access: yesJournal of Atmospheric and Oceanic Technology, 2009
Abstract This study investigates the potential for estimating mixed layer depth by taking advantage of the radial gradients in the radar reflectivity field produced by the large vertical gradients in water vapor mixing ratio that are characteristic of the mixing height. During the day, this relationship often results in a ring of maximum

Vertical Variations of Submesoscale Motions Between New Jersey Shelf and Bermuda

open access: yesFrontiers in Earth Science, 2022
Based on the measurements from the Oleander Project, the behaviors of submesoscale motions are examined in the area between New Jersey Shelf and Bermuda. The vertical variation of Rossby number, the kinetic energy in the submesoscale range, and the power

Tracer dynamics in two-layer density stratified estuarine flow [PDF]

open access: yes, 2014
This paper considers tidal-driven particle motion in Tampa Bay, Florida, USA under fully stratified conditions with riverine inflow. The flow field is modelled by means of the two-layer shallow-water equations solved on an adaptive quadtree grid using a

Using dissolved oxygen concentrations to determine mixed layer depths in the Bellingshausen Sea [PDF]

open access: yes, 2011
Concentrations of oxygen (O<sub>2</sub>) and other dissolved gases in the oceanic mixed layer are often used to calculate air-sea gas exchange fluxes. The mixed layer depth (<i>z</i><sub>mix</sub>) may be defined using

Aggressive prostate cancer is associated with pericyte dysfunction

open access: yesMolecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

Physical Drivers of Phytoplankton Bloom Initiation in the Southern Ocean's Scotia Sea [PDF]

open access: yes, 2019
: The Scotia Sea is the site of one of the largest spring phytoplankton blooms in the Southern Ocean. Past studies suggest that shelf‐iron inputs are responsible for the high productivity in this region, but the physical mechanisms that initiate and ...
