INCORPORATING SAMPLING VARIATION AND RANDOM READER ERROR INTO CALCULATION OF EFFECTIVE SAMPLE SIZE IN THE APPLICATION OF AGE LENGTH KEYS TO ESTIMATION OF CATCH-AT-AGE PROPORTIONS
declined from a maximum of around 6 to 8 down to close to 1 as the aged sample fraction increased from 1 ... , with a corresponding range of around 4 down to 1. This reduction is due to the way the ageing error ...

A quantified Bayesian maximum entropy estimate of Antarctic krill abundance across the Scotia Sea and in small-scale management units from the 2000 CCAMLR survey
. During the survey, data were integrated at approximately 1 nm intervals, resulting in 9,586 observed data ... points. We therefore inferred the krill density on a 1 nm × 1 nm grid of pixels. Density values (g m-2 ...
