We allowed 2 × 10 burn-in steps then sampled over a further 2 × 10 steps.
In each home, continuous PM concentrations were sampled over a range of particle sizes.
For each country, 7 10 study fields were sampled over a gradient of increasing proportion of semi-natural habitats in the surrounding landscape.
Sampling followed a modified BACI design, where control and impact sites were sampled over a period of 22 months, before and after logging.
Plant communities were sampled over a large (∼600 000 ha) semi-arid landscape in western Colorado, within piñon juniper woodlands, sagebrush shrublands, and grasslands, and over conditions ranging from relict areas without livestock grazing to heavily utilized areas.
The method described in this paper uses a series of artificial neural networks (ANNs) in a framework combined with a feature vector that is composed of image intensities sampled over a stencil neighborhood.
Oil slicks on the ocean surface emitted from natural marine hydrocarbon seeps offshore from Coal Oil Point in the Santa Barbara Channel, California were tracked and sampled over a 2-h period.
The methodology was based on a multi-factorial design where the total number and the abundance of urchins in each of six size classes were sampled over a range of spatial scales, from 10s of cm to kms, and a temporal scale of five months.
More than 30 sites were sampled over a year, grouped in 7 zones, covering three periods: an aftermath period of a circumstantial category 2 hurricane (November and December 2011), a dry season (February June 2012), and a rainy season (July December 2012).
Litterbag experiments were designed to evaluate the effects of the type and location of plant residues (above- or belowground) by placing litterbags of aboveground plant residues on the soil surface or within the soil, which were sampled over a whole year.
A full-scale AD plant utilizing cattle manure and energy crops was sampled over a period of 12 weeks.
