The Hatfield Marine Science Center’s Thursday research seminar series continues online.  This week’s offering, at 3:30 p.m. on Thursday, Dec. 16, has the provocative title, “A Study of Radioactive Fish Ears or How I Learned to Stop Worrying and Love the Bomb.”  The event is free and open to all.

The speaker is, no, not Dr. Strangelove, but rather Andi Stephens, a research fisheries biologist with NOAA’s Northwest Fisheries Science Center, located at the Hatfield Marine Science Center.  Her description of her talk:

“Age validation has long been recognized as critical to the assessment process.  It is analogous to calibrating scientific instruments.  Imprecision occurs when multiple reads report different ages, and bias is a systematic under- or over-estimation; these are confounded in aging lab settings.  Imprecision in terms of between-reader variability can be quantified and addressed, for example using age-error matrices in stock assessment models.  Bias can only be uncovered by an age-validation study.  I will discuss these issues and present several examples of recent work.”
