They want to understand how these apex predators adjust to changing ocean temperatures, particularly during marine heat waves. Plus, an international collaboration involving a high-tech German research vessel is exploring New Zealand’s deep-sea realm. Guests: Eva Ramey, PhD candidate, Victoria University of Wellington Dr Alice Rogers, Victoria University of Wellington Coastal Ecology Lab Dr Kareen Schnabel, NIWA Professor André Freiwald, Senckenberg am Meer Research Institute Dr Cornel de Ronde, GNS Learn more: Read the accompanying article.
