Abstract: Chemical analyses of herring otoliths can be used to consider the effect the Exxon Valdez Oil Spill continues to have on the recovery of the herring population in PWS. Studying the regional elemental signatures within the core of the herring otolith enables researchers to identify the spawning areas (Objective 1), and the edge of the otolith will identify nursery area (Objective 2). The 3D-PWS model describing larval drift and larval retention in PWS (Norcross et al., 2001a) has never been field-tested. Comparing the two methods for describing larval drift could validate this model as a tool for understanding the impediments to herring recovery in PWS (Objective 3). With these otolith chemical data combined with the 3D-PWS model, fishery managers will have the tools necessary to better predict recruitment and estimate herring spawning habitat recovery.
