Manta ray Survey with Manta Watch New Zealand
NEO
Auckland, New Zealand
December 13 - 15, 2024
Project Overview
Oceanic manta rays are critical to marine ecosystems, serving as indicators of ocean health and linking nutrient cycles across vast areas. However, their presence and behaviors in New Zealand waters, particularly the Hauraki Gulf, are not well understood. Focused research on these rays is vital for uncovering their seasonal movements and ecological roles, informing strategies to ensure their conservation.
Application
By studying oceanic manta rays in New Zealand, researchers can better understand their seasonal patterns, habitat preferences, and ecological impact. This knowledge is crucial for developing targeted conservation measures and fostering sustainable marine management practices. Insights from this work will contribute to the global understanding of manta ray behavior and their role in marine ecosystems.
Expedition Summary
From December 13th to 15th, 2024, The International SeaKeepers Society South Pacific facilitated a three-day expedition in the Hauraki Gulf aboard DISCOVERY Yacht NEO. The team surveyed key regions, starting from Great Barrier Island and heading toward the Hen and Chicken Islands, Mokohinau Island, and the northeast and southeast coasts of Little Barrier Island, before concluding along the west coast of Aotea/Great Barrier Island.
Although no manta rays were encountered, the timing of the survey early in the season provides valuable data on their potential movements and habitat preferences. The team documented a thriving gannet colony, six little blue penguins, and conducted extensive drone surveys. With warm blue waters and a temperature of 20°C, the expedition offered key insights and baseline data to guide future research efforts in the Gulf.
