Principal Investigator (PI): Dan Rosenberg, Alaska Department of Fish & Game

Assisting Personnel: None

Research Location: Prince William Sound

Restoration Category: Monitoring

Injured Resources Addressed: Harlequin Ducks

Abstract: Collective results of harlequin duck studies of western Prince William Sound (PWS) following the EVOS indicate serious breeding and population concerns. However, no conclusive evidence of histological or physiological effects from oil has been found. To date, EVOS projects have gathered abundance and distribution data only on total harlequin duck populations, with little information on sex and age composition, or proportions of paired birds. Currently, there are no sufficiently measured parameters of harlequin population dynamics with which to construct a population model for PWS. This project will provide a new tool for establishing quantified restoration goals and will design an effective monitoring program for harlequin ducks in PWS. Shoreline surveys will be conducted using visual assessments by multiple observers, photography, videography, and other prospective means of capturing sex and age data. Data analysis will include quantification of class data from visual observations and other media, comparison and corroboration of data among methods, and statistical description of results.
