Linking marine mammal and ocean health in the ‘New Normal’ arctic

The ‘New Normal’ Arctic ecosystem and the reliance of indigenous people on marine mammals for subsistence makes urgent the need for a comprehensive marine mammal health monitoring program linked to regional ocean observing systems. An Arctic-focused Marine Mammal Health Map (MMHM) framework could be initiated via expansion and coordination between regional Ocean Observing Systems and Community-based Monitoring Programs. In the US, this approach would build upon three activities currently supported by the Alaska Ocean Observing System (AOOS): ocean data access, community based monitoring and spatial tools for data visualization. The new MMHM framework would support a more holistic understanding of climate change impacts to ocean ecosystems, aid in the prioritization of management efforts to mitigate impacts to marine mammals and complement marine ecosystem monitoring programs fostered by the Arctic Council and UNESCO. Ultimately, we advocate for the inclusion of MMHM products as ‘essential ocean variables’ in the Global Ocean Observing System
