A series of criteria were created for the removal of variables from the model in order to create the optimal model for each depth zone
, as follows: (1) the single variable with the lowest absolute t value from the table of multiple regression coefficients was removed; and (2) a variable was only removed from the model if the change in the regression sum of squares was not statistically significant at P <0.05, as described below.
Sighting rates were calculated for each depth zone
to compare the monthly and seasonal relative densities (whales per km) for both bowhead and beluga whales (summer is July and August; fall is September and October).
(1998) compared depth at initial capture with depth at recapture and found that northern fish congregated at depths of 400-800 m, whereas southern fish were more likely to be recaptured in the same depth zone
as that of tagging.
For 2D + Z applications, it can be assumed that the object of interest is located in a specific depth zone
. This depth range which is provided as an input of our global coding scheme defines the Depth of Interest (DoI).
To compare abundances of functional groups among habitats, 1-way ANOVAs, with depth zone
considered as a fixed factor and abundance per site and year as replicates were used.
Here, the definition of water column refers to the depth zone
along the coast, a range.
It is visible from the map that for this depth zone
most of the districts show lower range of correlation coefficient (light green and sky blue color).
An intermediate resistivity layer ranging from 101 to 218 U m at the intermediate depth zone
, which could be represented as weathered to moderately weathered rock material.
The completion of an update of the resource estimate for the mine's Depth Zone
has increased to 46 million pounds of contained nickel in the indicated category to 113 million pounds as of March 2007.
Statistical analyses focused on ANCOVA using factor scores as the dependent variables, the total number of clams caught per tow as the covariate, and depth zone
and latitudinal zone as main effects.
Roots were observed at all depth zones
for all mixtures, and the relative differences in total root mass response among root zone treatments were generally evident in root mass assessed at all four 75-mm depth zone
The pole CCA retention values are reported by age group, position (above and below the ground), and species for each depth zone
in Table 1.
