Great Lakes is paid only for the sand that can be measured on the beach, so the workmen wanted to keep the sand there until a large three-legged contraption called the CRAB, which stands for Coastal Research Amphibious Buggy, could be maneuvered into place to measure the beach's profile.
Concentrations of PAHs measured in the beach sand samples are shown in Table 1.
Imagine you have a ruler and you're tasked with measuring the height of the ocean at a beach.
Sections of synovium were scanned with EPSON Expression XL 10000 scanner (Epson America Inc, Long beach, CA, USA) for measuring the synovial biopsy area with AxioVision Rel 4.8 software (Carl Zeiss Ltd., Welwyn Garden City, UK).
The team will measure the rate of beach erosion, and record where the sand migrates, to help future projects.
From March to August, visitors to St. Lucia can take a Turtle Watch tour run by Heritage Tours (www.heritagetoursstlucia.org), where guests camp overnight on the beach and help measure the leatherback turtles and count the number of eggs they lay.
The freshwater concentration of a beach sample measures the physical dilution due to the mixing of the stream flow with the marine water.
In this paper, these forecasts are shown to be worse than the trivial forecast in which the most recently measured beach volume persists unchanged into the future, with a mean square error (MSE) about 13.5% worse (equivalent to a root mean square error (RMSE) 6.5% worse).
The two best methods improve on the persistence of the most recently measured beach volume by about 15% MSE (8% RMSE), and on the presently used linear least squares trend method by about 25% MSE (13.5% RMSE).
Besides, he said, by the time the laborious measuring process was completed, the beach would have changed its shape anyway.
