  • Design objectives & criteria

  • Product design specifications

  • Product design

  • Design alternative

  • Conclusion & future plans


Problem statement l.jpg
Problem Statement

Currently there is no device that allows field researchers to extract blood samples from free-ranging large cetaceans. Developing a tool where blood can safely be taken from whales in the wild would mark a breakthrough in current technology and allow for subsequent studies to focus on critical physiological indices necessary for maintaining the general health of cetacean populations.
