Arctic Observing Network

In the next five years, the Center will increase capacity to support big data from satellites, remotely operated aircraft, and sensor networks. “Our next phase of operations will be exciting as we engage with researchers earlier in their research cycle” says Matthew Jones, PI for the award and Director of Informatics Research at NCEAS. “Through training, direct support, and a variety of new data management services such as tools for assessing data quality and sharing interactive data visualizations within research groups before the data are published, the Arctic Data Center will facilitate collaboration for lab and field groups, while also improving reproducibility across Arctic research.”

MOSAiC Expedition

Embark on the largest polar expedition in history: in September 2019, the German research icebreaker Polarstern set sail from Tromsø, Norway, to spend a year drifting through the Arctic Ocean - trapped in ice. The goal of the MOSAiC expedition was to take the closest look ever at the Arctic as the epicenter of global warming and to gain fundamental insights that are key to better understand global climate change. Hundreds of researchers from 20 countries were involved in this exceptional endeavour. Following in the footsteps of Fridtjof Nansen's ground-breaking expedition with his wooden sailing ship Fram in 1893-1896, the MOSAiC expedition brought a modern research icebreaker close to the north pole for a full year including for the first time in polar winter.


AOOS works with agencies and other organizations to provide coastal and ocean data and information products to the public through collaborative networks and our online Ocean Data Explorer portal. Explore select portal highlights below.


The Arctic Research Consortium of the United States (ARCUS) has been connecting Arctic research and education since 1988. Guided by our Values, we bridge Arctic research across organizations, disciplines, geographies, sectors, knowledge systems, and cultures. Based in the United States, ARCUS serves a globally connected, diverse Arctic research community, with an emphasis on connecting U.S. researchers.


Welcome to the College of Fisheries and Ocean Sciences, where our world-class faculty educate future leaders in fisheries and marine science. Our research addresses pressing issues in aquatic ecosystems from the Arctic to Antarctica. We invite you to explore our website and welcome any questions you may have.

All About Seaice -- NSIDC

Sea ice is found in remote polar oceans. On average, sea ice covers about 25 million square kilometers (9,652,553 square miles) of the Earth, or about two-and-a-half times the area of Canada. Because most of us do not live in the polar regions, we may live for several decades and never see sea ice. Although it may not directly affect us, it is a critical component of our planet because it influences climate, wildlife, and people who live in the Arctic.

Seasonal Ice Zone Observations -- Sizonet

The Local Observations database was developed to record, archive, and share indigenous sea ice knowledge and expertise. This information is generously shared with the public by the observers and the communities within which the observers reside. We ask that anyone interested in browsing or using the information review and agree to adhere to the ethical and appropriate use guidelines.

Project Jukebox

This project includes oral history recordings of residents of northern Alaska talking about sea ice conditions, observations over time, and changes that are occurring. The collection includes archival interviews recorded from 1978 to 1980 as part of a study related to potential offshore oil development, and from 2008-2009 as part of a Geophysics Ph.D. project about sea ice thickness along spring whaling trails offshore of Utqiaġvik (Barrow).
