The most convincing relationships documented here related to environmental variables such as SST, latitude, reef width and proximity to large estuaries irrespective of human disturbance levels.
Six rectangular fault parameters (i.e., longitude, latitude, length, width, rake, and slip amount) were the free parameters estimated in the inversion.
The goals were to: (1) quantify the abundance and patterns of distribution of RSDs along the entire 1200 km California coast, and (2) test the generality of previously described or predicted relationships between RSD occurrence and geographic, oceanographic and geomorphic parameters, including depth, wave energy, latitude, shelf width, and proximity to bedrock reefs and headlands.
Actually, multi-instrumentation observations showed that the equatorward boundary of the high latitude Doppler spectral width can be interpreted as co-locating with the open-/closed-field line boundary (Milan et al. 1999).
The single rectangular fault modeling routine estimates 12 parameters: nine fault parameters (latitude, longitude, depth, length, width, strike, dip, rake, and slip) and a translation parameter for the east, north, and vertical directions that accounts for the common-mode noise.
A sinuous dark ribbon has been seen along a latitude circle with a width of ~ 500 km and with wavelength varying from ~ 800 to 1200 km in one 2.32-µm image (Fig. 17) that separates a darker region toward the equator and brighter region south of it toward the pole.
We determined the slip velocity U, latitude ( lambda ), longitude ( varphi ), width W and length L of faults such that ( Vleft( {U,varphi,lambda,W, L} right) = mathop sum limits_{i} left[ {left( {O_{E} - C_{E} } right)^{2} + left( {O_{N} - C_{N} } right)^{2} } right]/sigma^{2} ) was minimized using a grid search algorithm.
Indeed, in that case, there are many new factors that would be necessary to be taken into account such as the effects of site latitude, planting density, row width and azimuth.
On the contrary, most of the echoes identified as SAPS (with close SYM-H-latitude relationships) have spectral width wider than 40 Hz, indicating that their characteristics are different from mid-latitude F-region echoes.
