Not exact matches

Errors in depth measurement are less than +0.05 m, and +0.02 - 0.03 g cm - 3 is the error due to density variation.

The mass balance determined from a density of 1 to 2 points / km2 (10 and 20 measurement sites) was significantly in error, unlike on Columbia Glacier this error is not consistently negative, overestimating mass balance in 1984 and underestimating mass balance in 1998 (Figure 6).

Cogley (1999) referred to the use of this density of measurements to eliminate all but measurement error, as reductio ad absurdum.

In this study, we approach the issue of errors resulting from measurements networks of varying densities from a purely field measurement perspective.

If the measurement for carbon - 14 age has Gaussian error with standard deviation 100 (as seems about right for Nic's Fig. 2), and the measurement is rounded to one decimal place, and the calibration curve maps calendar age 750 to carbon - 14 age 1000, then the probability of the observation being 1000.0 given that the calendar age is 750 is 0.1 (for one decimal place) times the probability density at 1000 of a Gaussian distribution with mean 1000 and standard deviation 100, which works out to 0.0004.

A better indication of intrinsic error in stomatal reconstructions is the (+ / --RRB- 18 ppmv Finsinger, et al., give for the training period, where modern stomatal density or stomatal index is regressed against modern CO2 measurements.

In an examination of the error in mass balance measurements using different sampling densities, it was noted on the Columbia Glacier that the total number of measurements necessary to achieve consistent accuracy within +0.10 was 40 points (Pelto, 2000).

The use of a high measurement density and consistent methods provides that errors resulting from an imperfectly representative measurement network are largely consistent and correctable (Pelto, 1996, 1997, 2000).
