Arctic Ocean

Navigating the New Arctic (NNA) is one of NSF's 10 Big Ideas. NNA projects address convergence scientific challenges in the rapidly changing Arctic. The Arctic research is needed to inform the economy, security and resilience of the Nation, the larger region and the globe. NNA empowers new research partnerships from local to international scales, diversifies the next generation of Arctic researchers, enhances efforts in formal and informal education, and integrates the co-production of knowledge where appropriate.

As the Arctic thaws, new opportunities for resource exploration and the opening of new trade routes are expected. Increased passage of commodities through these routes and the related industrialization of the Arctic will introduce both opportunities and risks. These will require international agreements and rules of governance to maintain global stability and protect not only the commercial viability of the U.S. Arctic, but also the local peoples, environment, and natural resources.

This project advances the national health, prosperity, and welfare by developing and demonstrating a new robotic technology for persistent, autonomous observation of under-ice marine environments over large (>1000 km) spatial scales. The Arctic is undergoing rapid change, with dramatic shifts in the sea ice cover and upper ocean. Monitoring and understanding these changes is critical to improving our ability to predict ongoing change and variability on seasonal to decadal timescales.

Changes in Arctic sea ice have wide-ranging societal and ecological impacts. The opening of northern shipping routes, reliability of ice roads for access to coastal communities, and extraction of undersea resources have economic implications for countries around the world. Indigenous peoples depend on local marine mammal populations as a source of cultural and nutritional value, however Arctic marine mammals are particularly vulnerable to reductions in sea ice cover as have been occurring for more than 30 years.

The Arctic has been experiencing significantly longer ice-free, navigable maritime seasons, thereby changing the types of activities taking place in Arctic waters. Cruise ships are travelling through the Northwest Passage, oil exploration is occurring off the North Slope of Alaska, and the Northern Sea Route is seeing an increasing volume of cargo ships travelling through it.

The Pacific sector of the Arctic Ocean is warming, in particular the shallow Chukchi Sea. As a result, it is anticipated that many organisms may migrate northward or become more abundant as air and ocean temperatures continue to warm.  However, few pose such significant threats to human and ecosystem health as harmful algal bloom (HAB) species.
