Tim Sippel (pictured above, centre, image by Arthur Cozens) is a PhD student working with John Montgomery at the University of Auckland's Leigh Marine Laboratory. He is using satellite tags to study the movements of Pacific bluefin tuna and striped marlin (tracking map below, courtesy of Tim Sippel). This research is carried out co-operatively with Blue Water Marine Research, Stanford University's Tagging of Pacific Pelagics Program and with recreational game fishers.
