Lynker Helps NOAA deepen Understanding of Humpback Whales

Hawaiian Islands Humpback Whale National Marine Sanctuary (HIHWNMS) Research Specialist and Lynker employee Eden Zang served as lead bioacoustician on a two week expedition to the Papahanaumokuakea Marine National Monument (PMNM) aboard research vessel Searcher ( The mission focused on the deployment of five acoustic recorders in various locations across PMNM as well as a planned recovery of one acoustic recorder at Maro Reef that was  deployed in October 2018. In addition, Lynker will help document and interpret the overall research process for future use in Sanctuary education and outreach efforts.
The passive acoustic recorder packages will help NOAA study the presence and distribution of humpback whales in PMNM waters. Our personnel will also help monitor additional biological and anthropogenic sources of sound that contribute to the soundscape of the Greater Pacific region. These recorders are part of the national NOAA/SanctSound project examining soundscapes across seven national marine sanctuaries and one marine national monument. This program is a continuation of ongoing monitoring and research and will help NOAA measure sound levels and characterize acoustic conditions in sanctuaries.

Significance: Advances the management plan’s objective to deepen and enhance understanding of humpback whales and their habitat by exploring the way humpback whales in the central North Pacific Ocean utilize different areas in waters off Hawaiʻi.
