The intercept method
correctly identified the dominant species that matter most for coral bioerosion: those that can invade live coral, display fast growth, and produce large individuals (Table 2).
The line intercept method
(also known as the line intersect method) was introduced by Canfield (1941) as a means of determining the areal coverage of terrestrial plant species.
The later was measured by the standard lineal intercept method
over 10 selected fields of views.
The easiest way to measure SDAS is to use the linear intercept method
. This is illustrated in Fig.
In the UAE, we decided this was not possible and used a random street intercept method
. This was partly also because the length of the survey, at around 40 minutes, traditionally requires face-to-face contact.
The microstructure of the material was evaluated using SEM (scanning electron microscope) whereby the grain structures and grain sizes were determined using the average grain intercept method
. The average grain intercept method
is used to measure the grain size of a material by drawing randomly positioned line segments on the micrograph, counting the number of times each line segment intersects a grain boundary, and finding the ratio of intercepts to line length.
To access participants, we used the street intercept method
, a nonprobability sampling technique whereby people are approached on the street and asked if they are prepared to allocate a few minutes to complete an anonymous questionnaire (Simbayi et al., 2006).
In this case, as the linear intercept method
is being applied with an equidistance of 1 pixel between line probes, the total number of pixels belonging to the POI is equal to the total length of all test lines across it.
Laney used two custom built LDD-750 drilling rigs to drill the pilot hole using the intercept method
. Crews drilled from both the east side and the west side of the lake simultaneously until both pilot bits were in the same hole.
For example, the line intercept method
is commonly discussed in the booklet since it is quick and therefore cost-saving.
The NAFB is using the mall intercept method
of research at farm shows across the country, which means you may be asked to fill out a survey as you mill around tents and farm show exhibits.
