Data

Here the the user can explore the data sets for demographic models and population viability analysis (PVA) of threatened northern resident killer whale (NRKW) populations and endangered southern resident killer whale (SRKW) in the north-east Pacific Ocean. 

The data are broken down into several categories covering:

  • Abundance data for the salmon populations on which the killer whales depend for their food source;
  • Census data for the two killer whales populations (northern resident and southern resident) over many years, dating back to 1973; 
  • Exploitation rate indicator stock data;
  • Stock aggregates Terminal Run Equivalents (TRE) data.

This website is a demonstrator for the integration of several informatics technologies useful in "in-silico" biodiversity science: Scratchpads, Taverna Player and BioVeL infrastructure for executing workflows. This particular example makes use of population census data for Killer Whales and abundance data for Chinook Salmon in the north-east Pacific Ocean, which has kindly been provided by Antonio Velez-Espino of Fisheries and Oceans Canada. Please do not rely on the data or results information provided for any actual scientific, conservation or policy use.
