We received a Pre-Activity Notification and Initial Environment Assessment from Oregon State University (OSU) under Regulation 11(a) of the EEZ (Environmental Effects–Permitted Activities) Regulations to conduct marine scientific research in the South Taranaki Bight. OSU, in collaboration with NIWA, intended on deploying five marine autonomous recording units (MARUs) to monitor for the presence of acoustically-active marine species, specifically low-frequency baleen whales (such as blue whales). The MARUs will be deployed to the seabed using an iron anchor. Over a two-year deployment period starting in January/February 2016 (with 6 monthly refurbishments), the units acquired and storde acoustic data. At the end of the deployment, the recording units were acoustically released for final retrieval, leaving the anchors on the sea floor to dissolve over time.
