3) The standard deviations of the SST anomalies in the HadISST1.1 dataset are 0.2–0.4°C smaller prior to 1949 than after 1949. This nonstationarity could complicate interpretations of the long HadISST1.1 data record for some studies of climate variability. It is likely attributable mostly to the improved sampling of SST observations...

In situ observations of tidally driven turbulence were obtained in a small channel that transects the crest of the Mendocino Ridge, a site of mixed (diurnal and semidiurnal) tides. Diurnal tides are subinertial at this latitude, and once per day a trapped tide leads to large flows through the channel...
Cells in three-dimensional (3D) environments exhibit very different biochemical and biophysical phenotypes compared to the behavior of cells in two-dimensional (2D) environments. As an important biomechanical measurement, 2D traction force microscopy can not be directly extended into 3D cases. In order to quantitatively characterize the contraction field, we have developed...
Regulating fishing trough overall catch limits, sometimes referred to as olympic fishing, has been heavily criticized by fisheries economists for its unhealthy incentives for overcapacity, excessive costs, quantity focus and uneven supply patterns. In spite of this the Icelandic government opened an olympic style coastal fishery for small scale vessels...
Many aquatic habitats in coastal Oregon have been impacted by historic land use practices that led to losses of in-stream wood and associated degraded fish habitats. Many of these streams are now bordered by stands of dense second growth forests (30–80 years) that are incorporated into riparian buffer zones with...
Magnetic composites containing anisotropic magnetic particles can achieve properties not possible in corresponding bulk or thin films of the magnetic material.
