AAOKH supports information exchange and environmental observations of cryosphere change by Inupiat experts in coastal communities. Community involvement throughout the development of AAOKH is ensuring that observations support key community concerns related to snow, ice and permafrost change. Concerns include impacts to food security, safety, and access to subsistence resources.
AAOKH provides relevant information and a user-friendly interface for coastal communities and stakeholders interested in the intersection of cryosphere change and coastal Inupiat community concerns.
Why is this work important?
AAOKH contributes to IARC efforts to synthesize observational data and helps build capacity in coastal communities by allowing them to help direct community observations related to their concerns on cryosphere change.
Integration of traditional knowledge with current science will help fill a need highlighted in the National Strategy for the Arctic Region, the Alaska Arctic Policy Commission, and recommendations of the Arctic Council Sustainable Development Working Group, thus making AAOKH activities relevant at state, national and international levels.

The AFSC strengthens the link between fire science research and on-the-ground application in Alaska by promoting communication between managers and scientists, providing an organized fire science delivery platform, and facilitating collaborative scientist-manager research development.
The area burned each year in Alaska varies widely, ranging from a few hundred thousand to several million acres. The extent and severity of wildland fire in Alaska appear to be increasing with climate change. Models indicate that this increase will continue: fire will feedback to climate by releasing stored carbon as greenhouse gases and black carbon particulates, and by exposing permafrost and speeding its thawing.

Why is this work important?
Since 2004, wildfires have burned more than 38,000 square miles in Alaska — an area larger than the state of Indiana. Eighty percent of Alaskans live in the wildland-urban interface and are potentially vulnerable to wildfire. Smoke impacts public health, infrastructure, and transportation.
Alaska’s large proportion of public lands means that many fires are allowed to burn freely and play their natural ecological role. Wildland fire in Alaska is managed on an interagency basis by both federal and state agencies. These agencies are under continual budget pressures, and improved information to guide their decisions is one of the few ways they might increase efficiency.

The U.S. Department of the Interior’s Climate Adaptation Science Centers (CASCs) provide scientific information, tools, and techniques that those interested in land, water, wildlife, and cultural resources can use to anticipate, monitor and adapt to climate change. The AK CASC is one of eight such centers located throughout the nation.
The AK CASC works to increase our understanding of how Alaska’s ecosystems and resources are responding to a changing climate. This is done by building partnerships between academic scientists, state and federal agency scientists, resource managers, tribal leaders, and decision makers.
We use these partnerships to anticipate, monitor, research, synthesize and communicate, and sustainably manage resources across Alaska’s diverse social-ecological systems.

Why is this work important?
Climate change is having—and will continue to have—a significant impact on Alaska’s resources and human populations. Furthermore, almost 90% of Alaska’s land is managed by state and federal agencies.
In order to provide realistic forecasts of potential changes and manage natural resources under future scenarios, collaboration and efficiency between state and federal agencies and the larger scientific community are essential. The AK CASC provides an umbrella under which appropriate research efforts and other strategies can be identified, and they support research in physical, biological, social, and integrated systems that can be applied to issues being faced by resource management agencies.

As of June 30, 2018, CIFAR reached the end of its 10-year life cycle. CIFAR has requested and received a one year no-cost extension in order to allow currently funded projects to operate, as needed and appropriate. We are waiting to hear more about what funding mechanisms will be available for future collaborations between NOAA and UAF.
The Cooperative Institute for Alaska Research (CIFAR) is one of 16 National Oceanic and Atmospheric Administration (NOAA) Cooperative Institutes.
CIFAR helps match Alaska’s research talent with NOAA opportunities in:
- Ecosystem function - Gain sufficient knowledge of Alaska’s ecosystems to forecast their response to natural and anthropogenic change
- Coastal hazards - Learn more about coastal hazards, storms, and tsunamis that affect Alaska's population, ecosystems, and coast to improve weather forecast and warning accuracy
- Climate change and variability - Foster climate research targeted at societal needs. Advance Arctic climate research to improve predictive capacity of climate variations affecting coastal regions and ecosystems.
CIFAR also facilitates collaboration between NOAA and academic scientists and partners in the private sector, local government, and tribal organizations.
Why is this work important?
This is a critical time for the Arctic, where rapid change coincides with shrinking research budgets, making the need for cooperation and coordination of Arctic observations vital in order to address anticipated environmental challenges.
CIFAR helps partner key scientists with opportunities at NOAA, contribute to integrating environmental information across Alaska, and as part of IARC can serve as a conduit for international partnerships.

There is currently no international hub for distilling information relevant to Arctic change and making it available to broader audiences. This is an opportunity for IARC and UAF to fill a needed void at the boundary of Arctic science and outreach.
The goals are to establish IARC and UAF as internationally recognized “go-to” sites for current information on the state and plausible trajectories of the changing Arctic environment, and to highlight research and observing UAF activities by broader distribution through an “Arctic portal.”
Why is this work important?
IARC has strong partnerships with Arctic experts in Russia, Japan, Canada, Germany, Norway, Korea, and China. The combination of existing expertise, ongoing activities, and collaborations provides IARC with a clear path to the establishment of a synthesis center and information distribution capability that will attract national and international usage and support.

The largest Central Arctic expedition ever
In September 2019 the German research icebreaker Polarstern will depart from Tromsø, Norway and, once it has reached its destination, will spend the next year drifting through the Arctic Ocean, trapped in the ice.
A total of 600 people from 17 countries, who will be supplied by other icebreakers and aircraft, will participate in the expedition – and several times that number of researchers will subsequently use the data gathered to take climate and ecosystem research to the next level.
The mission will be spearheaded by the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI).

NABOS is part of the Arctic Observing Network and is funded by the National Science foundation and the National Oceanic and Atmospheric Administration.
Since the early 2000s, NABOS has worked to compile a cohesive picture of climatic changes in the Eurasian and Makarov basins of the Arctic Ocean. Regular scientific cruises involving measurements of physical and chemical oceanography by means of moorings, buoys, and other instruments have helped NABOS researchers to understand:
- How boundary currents transport Atlantic Ocen water
- How Atlantic Ocean water interacts with shelf waters, the deep basin interior, and the upper ocean
- Changes in upper ocean circulation within these basins

Why is this work important?
The exceptional magnitude of recent high-latitude changes in the ocean, ice, and atmosphere strongly suggests a potentially irreversible shift in the Arctic Ocean to a new climate state.
These changes have important implications for the Arctic Ocean’s marine ecosystem—especially for those components that depend on sea ice or that have temperature- and stratification-dependent sensitivities or thresholds.
Addressing these and other questions requires careful observations. To these ends, expeditions provide key information about the historical transitions occurring in the Arctic Ocean.

The Next-Generation Ecosystem Experiments (NGEE Arctic) seeks to quantify the physical, chemical, and biological behavior of terrestrial ecosystems in Alaska.
Initial research will focus on the highly dynamic landscapes of the North Slope, where thaw lakes, drained thaw lake basins, and ice-rich polygonal ground offer distinct land units for investigation and modeling.
A focus on scaling based on investigations within these geomorphological units will allow us to deliver a process-rich ecosystem model, extending from bedrock to the top of the vegetative canopy, in which the evolution of Arctic ecosystems in a changing climate can be modeled at the scale of a high resolution Earth System Model grid cell (i.e., 30x30 km grid size).
Why is this work important?
Increasing our confidence in climate projections for high-latitude regions of the world will require a coordinated set of investigations that target improved process understanding and model representation of important ecosystem-climate feedbacks.
