In latitudes marked by distinct seasons, a seasonal thermocline at much shallower depths forms during the summer as a result of solar heating, and it is destroyed by diminished insolation and increased surface turbulence during the winter.
The recovery in frontier markets has been much shallower, leaving the index at less than half of its 2008 high, while the other two indexes have recovered nearly all of their lost ground.
In old, cool subduction zones, such as those in northern Chile and Alaska, the downdip limit of interplate earthquakes is much shallower than the depth at which the temperature of 350°Cis observed, but approximately corresponds to the intersection of the plate interface with the forearc Moho (e.g. Oleskevich et al., 1999).
In addition, the consistency between the change in measured stress and the change in seismicity in the Kamaishi regions suggests that the results of stress measurements, even those at a much shallower depth than the earthquake source fault, can be useful for understanding rupture-propagation behavior.
In this way, they obtain images as if they were taken at a much shallower depth than in reality.
The main discrepancy lies in the location of the maximum slip, which occurs at a much shallower depth in our model than in that of Ji and Hayes.
During the 1990s and early '00s, the downward trend persisted, albeit at a much shallower trajectory this time driven by falling mortgage interest rates and sizeable gains in real median family income.
The company's solution has been to build a system that bores a much smaller hole (a few inches is all that's needed) at a much shallower depth of hundreds of feet — making the installation something that can be done in less than a day.
Using a large macrofaunal dataset (>300 stations) from the Faroe-Shetland Channel, a similar pattern is observed, however the peak in diversity occurs at a much shallower depth of about 450 550 m (Figure 3c) [112] [113], [113].
Experimental enclosure approaches to determine UVB effects on egg stages have been criticized; for example, egg masses were placed at water depths much shallower than is typical for natural oviposition sites.
