Uncertainty in standard sphere calibrations
result, direct measurements of target strength (TS) were made of four standard spheres (WC- 33.2 and 38.1 ... mm, Cu- 23.0 and 30.5 mm) in an anechoic tank. A calibrated hydrophone was used to measure ... the incident and reflected intensities of the pulse and the measured TS values were compared ... to their theoretical counterparts. The TS measurements of the 30.5 and 23.0 mm Cu spheres and of the 38.1 mm WC sphere ...

Using effective sample sizes to evaluate the efficiency of length samples collected by at-sea observers in the krill fishery in Subarea 48.1
many krill should be measured by observers should measure (however see Thannasekos et al. 2012). We ... , to characterise how many krill are measured by observers, and for how many hauls. We then simulate the impact ... combination (effective sample size). The median number of krill measured per haul was around 200 (range 0-652 ... should be measured by observers should measure (however see Thannasekos et al. 2012). We used C1 effort ...
