A Change of Seasonality of the Upper Arctic Ocean in Response to Atmospheric and Sea Ice Forcing |
The PI proposes to investigate the change of seasonality of the Arctic Ocean Ekman transport and upwelling/downwelling, and their relationships to key components of the arctic system. A systematic investigation of the Arctic Ocean upwelling and its change of seasonality is needed in order to understand complex interactions among components of a rapidly changing arctic system. Upwelling is arguably the single most important dynamical variable in oceanography. It forces oceanic gyres through the Sverdrup balance. Upwelling replenishes nutrients in the surface layer and helps to sustain |

A Purpose-Driven Merger of Western Science and Indigenous Knowledge of Water Quality in Alaskan Communities |
Project AbstractThe well-being of Alaskan Indigenous communities depends on access to safe drinking water. However, water pollution has remained a reality for many of these communities due to naturally occurring and anthropogenic pollutants. As the climate warms, environmental changes will likely exacerbate water contamination problems by releasing entombed microorganisms, ancient organic carbon, nutrients, and metals through thawing of permafrost and melting of glaciers. While Alaskan communities are highly vulnerable to such changes, they also hold valuable Indigenous Knowledge about |

Arctic Surface Air Temperatures for the Past 100 years: Analysis and Reconstruction of an Integrated Data Set for Arctic System Science |
The Arctic has long been considered a harbinger of global climate change since increases in surface air temperature (SAT) over the globe are amplified in the Arctic. These increases in SAT have a profound impact on many other aspects of Arctic climate and ecology. For example, the thinning and decrease in area of Arctic sea ice has been attributed to increases in SAT, and many plant and animal species have been migrating further north.

Changing Seasonality of the Arctic: Alteration of Production Cycles and Trophic Linkages in Response to Changes in Sea Ice and Upper Ocean Physics |
Significant changes in the arctic environment have been detected in recent years. One of the most striking changes is the decline of arctic sea ice. A diminished arctic ice cover may have a profound effect on all components of the marine ecosystem. Despite the extreme polar conditions, the Arctic Ocean supports a complex pelagic food web that includes zooplankton, fish, birds, seals, walruses, whales and the top predator, the polar bear. At the base of the food chain, supporting all the marine life, are the phytoplankton and algae that produce organic carbon. The central hypothesis of this |

Collaborative Research on Sunlight and the Arctic Atmosphere-Ice-Ocean System |
The distinct annual cycle of solar radiation is a key defining feature of the Arctic system. The lack of sunlight in winter and the long daylight hours in summer structure both terrestrial and marine ecosystems, drive the seasonal build-up and sequestration of carbon and control the annual cycle of the surface heat budget. Recent research has also demonstrated that the seasonal photochemistry of snow over sea ice plays a major role in the cycling of major atmospheric constituents.

Terrestrial arctic ecosystems store 25.33% of the world's soil organic carbon (OC), and large amounts of the long-sequestered OC is rapidly released by erosion along the ~2000 km coastline of northern Alaska. This eroded OC becomes available for biogeochemical cycling and makes a substantial, but poorly known, contribution to marine ecosystems and to CO2 and methane emissions to the atmosphere; released OC can potentially alter biogeochemical cycling, increase CO2 and methane emissions, contribute to climate warming, accelerate sea ice retreat, increase fetch and wave energy to exposed coasts |

How the Timing of Summer Precipitation Affects the Responses of Boreal Forest to Climate Change |
There is increasing evidence that ecological processes at high latitude are just as sensitive to the timing of events as to their magnitudes. In the boreal forest, moisture availability in summer affects both tree growth and the fire regime. Summers are brief and seasonal transitions rapid, so even slight shifts in the timing of precipitation patterns can have large impacts. One of the most striking seasonal phenomena in the Alaskan boreal forest is the onset of frequent frontal storms in late summer. This event usually comes in mid-July but is delayed into August or even September in some |

Impacts of the Changing Seasonality of Wind-Driven Mixing on the Arctic System |
The Arctic is generally considered a very quiet ocean. The sea ice impedes the generation and damps both surface and internal waves - and mixing rates in the water column are consequently generally very small. When we start looking at specific events in more detail, however, we found that when there is no ice the Arctic Ocean is actually a pretty active ocean. Storms generate intense of inertial motions throughout the water column. These motions affect the stratification and the vertical distribution of properties in the water column.

Listen Up: Northern Soundscapes |
The Arctic has its own distinct rhythms. Up here, the sounds of natural forces, animals, and humans come together to create their own kind of music— soundscapes that murmur and boom, throb and hum, crack and cry, rustle and sing. Listening closely to the sounds and silences of the North opens up an intimate and resonant understanding of place.

Pan-Arctic Climate and Ecosystem Response to Historical and Projected Changes in the Seasonality of Sea Ice Melt and Growth |
The primary goal of this work is to explore the causes and effects of ongoing seasonal changes in the annual cycle of sea ice. This includes a quantitative assessment of the drivers and effects of the seasonal timing of sea ice melt onset, freezing initiation, and snowfall within the observational record and coupled climate model simulations of historical and future climate. We are examining this from both energy budget and ecosystem perspectives and are explicitly considering feedbacks to the Arctic and global systems. In particular, we are investigating the interactions between seasonal |

Project AbstractSignificant progress has been made to improve the accuracy both of short-term weather forecasts and longer-term climate, sea-ice, and other environmental forecasts. Nevertheless, there remains a forecasting gap on the scale from two weeks to a few months, especially in the Arctic. This subseasonal-to-seasonal (S2S) scale is important for planning subsistence hunting, commercial fishing, hazard response and risk mitigation, and other activities. This project supports development of improved S2S prediction capacity through a collaborative design process and workshop |

Savoonga Murre Monitoring |
OverviewMurres are a culturally important food source for people in Savoonga. During the spring, hunters harvest adult murres as they return to their breeding colonies and collect their eggs when they first lay them. After this initial burst of activity, the murres are left alone for the rest of the summer. We will install time-lapse cameras which will track the breeding success of murres. The images will be analyzed by high school students and the results will be reported locally to the Tribal Council and Native Corporation, and also internationally to the seabird working group (CBird) |

Seasons of Change in the Arctic Environment |
The arctic system is strongly defined by its seasonality. The extreme annual cycle of solar radiation, interactions between the Arctic and lower latitudes, within-arctic interactions between the land, ocean, and atmosphere, and the energetics of freeze and thaw, combine to lend a complexity and richness to arctic seasonality not seen elsewhere on the planet. This seasonality is changing. Summer sea ice extent is declining, attended by strong autumn rises in air temperature over the Arctic Ocean. Active layer freeze-up in Siberia is occurring later in the winter. These and other emerging |

Shifting Seasonality of Arctic River Hydrology Alters Key Biotic Linkages Among Aquatic Systems |
Our goal is to determine how the shifting seasonality of Arctic river hydrology alters key biotic linkages within and between lake and stream components of watersheds and may alter the function of the Arctic system. Arctic grayling (Thymallus arcticus) is a quintessential, circumpolar Arctic species that provides a model system for understanding the impacts of changing seasonality on arctic ecosystem function because an interconnected and varied landscape (large tundra rivers, small streams and lakes) is required to maintain their population viability.

Snow and Ice Processes in the Deposition and Fate of Mercury in the Arctic |
Atmospheric mercury enters the arctic ecosystem through a set of complex atmospheric chemical reactions that require sea ice and leads to provide reactive bromine, low ambient temperatures, and enough sunlight for photolysis. As a consequence, virtually all atmospheric mercury entering the arctic ecosystem is initially deposited in the snow pack, both on land and at sea. Up to one third of this initial deposit is re-emitted to the atmosphere before the snow melts, but the remainder ends up in snow melt run-off. The fate of this water-borne mercury is uncertain and undoubtedly different on land |

Soundscape Ecology to Assess Environmental and Anthropogenic Controls on Wildlife Behavior |
Project AbstractAcross North America, Arctic and boreal regions have been warming at a rate two to three times higher than the global average. At the same time, human development continues to encroach and intensify, primarily due to demand for natural resources, such as oil and gas. The vast and remote nature of Arctic-boreal regions typify their landscapes, environment, wildlife, and people, but their size and isolation also make it difficult to study how their ecosystems are changing. To overcome these challenges, autonomous recording networks can be used to characterize "soundscapes" |

Synthesis and Scaling of Hydrologic and Biogeochemical Data on the North Slope and Coastal Zones of Alaska: A Basis for Studying Climate Change |
The Arctic Ocean is the most landlocked ocean on Earth, and runoff from the pan-arctic watershed exerts strong control over ocean circulation and biogeochemistry. This project investigates the linkage between hydrologic variables and the fluxes of nutrients and organic matter (constituents) from the North Slope of Alaska to the Alaskan Beaufort Sea. The overarching goal of the work is to develop a generalized understanding of discharge-constituent relationships in arctic basins. The primary question is: What are the relationships between discharge and constituent concentrations in the three |

The Changing Seasonality of Tundra Nutrient Cycling: Implications for Ecosystem and Arctic System Functioning |
Arctic soils have large stores of carbon (C) and may act as a significant CO2 source with warming. However, the key to understanding tundra soil processes is nitrogen (N), as both plant growth and decomposition are severely N limited. However, current models of tundra ecosystems and their responses to climate change assume that while N limits plant growth, C limits decomposition. In addition, N availability is strongly seasonal with relatively high availability early in the growing season followed by a pronounced crash. There is a need to understand the controls on this seasonality to predict |

The Impact of Changes in Arctic Sea Ice on the Marine Planktonic Ecosystem - Synthesis and Modeling of Retrospective and Future |
Significant changes in arctic climate have been detected in recent decades. One of the most striking is the decline of sea ice concurrent with changes in atmospheric circulation and increased surface air temperature. This arctic warming trend is likely to continue into the future, leading to a diminished arctic sea ice cover that will significantly impact the arctic marine ecosystem and ultimately arctic and subarctic human communities. It is therefore critical to understand how changes in sea ice influence the marine ecosystem. To this end, this work will investigate the historical and |

The Impact of Climate Change on Glacial Fjords, Ecosystems, and Local Communities in Greenland |

Glacial meltwater and sediments released into the fjords make their waters nutrient-rich to the extent that glacial fjords, all over the Arctic region, are characterized by prosperous marine ecosystems, featuring a high density of seabirds, marine mammals, and fishes. As a result, many Arctic settlements are located near glacial fjords that, through their ecosystems, support hunting and fishing and contribute to the regional economy |

The Transition Zone of Upper Permafrost: The Frontline for Permafrost Changes Across Climate and Landscape Gradients |
Project AbstractPermanently frozen soils, or permafrost, often contain large amounts of ground ice, which make it vulnerable to climate change and human activities. These soils are protected from melting by a surface layer which thaws in summer and refreezes in winter, and a near-surface layer, termed the transition zone. This transition zone, which develops through complex interactions between the environment and permafrost, controls permafrost resilience to ground surface subsidence (thermokarst). Expectations are that as the climate warms, deeper seasonal melting will impact this |
