	abstract = {We used bomb radiocarbon (C-14) in this age validation study of Dover sole (Microstomus pacificus). The otoliths of Dover sole, a commercially important fish in the North Pacific, are difficult to age and ages derived from the current break-and-burn method were not previously validated. The otoliths used in this study were chosen on the basis of estimated birth year and for the ease of interpreting growth zone patterns. Otolith cores, material representing years 0 through 3, were isolated and analyzed for C-14. Additionally, a small number of otoliths with difficult-to-interpret growth patterns were analyzed for C-14 to help determine age interpretation. The measured Dover sole C-14 values in easier-to-interpret otoliths were compared with a C-14. reference chronology for Pacific halibut (Hippoglossus stenolepis) in the North Pacific, We used an objective statistical analysis where sums of squared residuals between otolith C-14 values of Dover sole and the reference chronology were examined. Our statistical analysis also included a procedure where the Dover sole C-14 values were standardized to the reference chronology. These procedures allowed an evaluation of aging error. The C-14 results indicated that the Dover sole age estimates from the easier-to-interpret otoliths with the break-and-burn method are accurate. This study validated Dover sole ages from 8 to 47 years.},

	abstract = {We used bomb-produced radiocarbon (C-14) to validate ages of Pacific ocean perch (Sebastes alutus), which are routinely estimated with the cut-and-burn method at the Alaska Fisheries Science Center (Seattle, Washington, USA). New statistical methods to compare Delta C-14 in validation samples with a reference chronology are introduced: (i) calculating confidence intervals around the LOESS-smoothed Delta C-14 reference chronology using simultaneous inference; (ii) purposely adding biases to the validation sample ages and then analyzing the sum of squared residuals of the validation samples{\textquoteright} Delta C-14 about the LOESS-smoothed reference chronology; and (iii) standardizing the Delta C-14 measurements from the validation sample to better fit the reference chronology. Standardized Delta C-14 measurements are particularly useful when researchers suspect that environmental and biological differences between the validation samples and the reference chronology may exist that affect the level, but not the timing, of Delta C-14 in the samples. These new methods can be applied simultaneously. Two previous bomb radiocarbon studies on canary rockfish (Sebastes pinniger) and black drum (Pogonias cromis) were reanalyzed, further illustrating the usefulness of these new methods.},
