A terrestrial survey, depth soundings and side scan sonar surveys were carried out to establish baseline topographic data.
A borehole survey (depth 150 m) was conducted in the central part of Motoyama, and it provides the only result that has been published (Ossaka et al. 1985).
In the borehole survey (depth 150 m) carried out near the northeast 900 m of the seismic array, alternating layers consisting of lava flows and pyroclastic rocks were found (Ossaka et al. 1985).
The method increases the survey depth of penetration because it galvanically injects electric current into the ground using a large-moment source and a long transmitter receiver distance (Abd Allah et al. 2013a).
The method, called grounded-electrical-source airborne transient electromagnetics, or GREATEM (Mogi et al., 1998), should enhance survey depth in coastal areas, since this method galvanically injects electric current into the ground.
Limitations include interspecific variability in behavioral responses to divers (some species flee, others approach divers), limited visual field of divers, inaccurate species identification of morphometrically similar species, and a limited survey depth range (<30 m).
Our analyses were based on quantitative surveys that measured the percentage of the bottom covered by living scleractinian corals on subtidal coral reefs (1 15 m depth, mean survey depth was 6.2 m) within ten subregions of the Indo-Pacific (Fig. 1, Table S1).
The first issue, dated June, was published in mid-May; it surveys, in depth, fresh, new-harvest olive oils from around the world.
IV surveys in depth the pitfalls for determinism that arise once things are allowed to get more interesting (e.g. by the addition of particles interacting gravitationally).
The aim of the surveys, in-depth interviews, case studies and observations was to obtain an in-depth understanding of the lives of adolescent women and their families.
