On comparison of

mean depth between the male and female the values were equal i.e.

Of local physical variables

mean depth (m), psammal (%), and xylal (%) substrates and of regional variables catchment area ([km.sup.2]) were statistically significant variables (Table 2).

Figure 6a and b show the maximum

mean depth profile and the wear rate for wear volume loss, respectively.

The study's calculation of the ocean's

mean depth is 3,682.2 meters-that's 21-to-51 meters less than previous estimates.

The first invertDCA axis resulted in positive correlations with water temperature,

mean depth and mean flow velocity.

Its surface area is 3555 [km.sup.2],

mean depth 7.1 m, and maximum depth 15.3 m (Jaani, 2001) (Table 1).

Beneath the Andes, the Nazca plate is horizontal and earthquakes have a

mean depth of 120 km as suggested previously based on scarce teleseismic data (Stauder, 1977; Tavera & Buforn, 2001).

Their report says the

mean depth of Diamond Lake is 22.5 feet and that the maximum depth is 48.5 feet.

Survey data were analyzed to produce five quantities that were descriptive of site topography: total site area,

mean depth (total site volume divided by total site area), percent of site area below the inlet, and the volume (both dimensional volume and percent of total volume) below a horizontal plane located 50 cm (19.7 in) above the inlet elevation.

Mean depth was calculated by dividing the sum of all the depth measurements for each lake by the number of sites on that specific lake.

For the analysis of the vertical distribution of the collected organisms, the

mean depth distribution during the day and night for each population of zooplankton and of fish larvae was calculated according to the Equation 1 of weighted

mean depth (WMD) of Frost and Bollens (1992):
