Investigating physical drivers of phytoplankton bloom initiation in the Northern Gulf of Alaska

Creator:: Ballantine, Kaleigh
Abstract:: The spring bloom is a key oceanic phenomenon in the Northern Gulf of Alaska (NGA), where it supports the regional ecosystem, fisheries, and CO2 sequestration. Despite its significance, mechanisms that trigger NGA blooms are still debated, largely due to a lack of sufficient data from late winter through spring. New...

Summary : Pacific Northwest Drought and Human Health Workshop

Creator:: Oregon Climate Change Research Institute, National Integrated Drought Information System, and University of Nebraska Medical Center
Abstract:: Drought can have substantial negative effects on human health, creating challenges for public health departments, emergency managers, and healthcare providers. For example, drought can lead to decreased water quantity and quality, increased incidence of illness or disease, increased mortality rates, and adverse mental health outcomes, especially as livelihoods are affected....

Boom-bust Cycles in Gray Whales Associated with Dynamic and Changing Arctic Conditions

Creator:: Stewart, Joshua D., Joyce, Trevor W., Durban, John W., Calambokidis, John, Fauquier, Deborah, Fearnbach, Holly, Grebmeier, Jacqueline M., Lynn, Morgan, Manizza, Manfredi, Perryman, Wayne L., Tinker, M. Tim, and Weller, David W.
Abstract:: Climate change is impacting a wide range of global systems, with polar ecosystems experiencing the most rapid change. While climate impacts affect lower trophic level and short-lived species most directly, it is less clear how long-lived and mobile species will respond to rapid polar warming, as they may have the...

Mapping Wildlife-Relevant Snow Properties in Arctic-Boreal North America; Novel Modelling, Remote-Sensing, and Ground Observation Approaches

Creator:: Cosgrove, Christopher Liam
Abstract:: Arctic-boreal regions are exhibiting the symptoms of profound ecological shifts as they experience pronounced warming. Wildlife in high-latitudes are one such harbinger of change, and their populations are undergoing range-shifts, declines, and extinctions in response to their rapidly altering habitats. As the circumpolar and boreal north is snow-covered for up...

A Multivariate Analysis of Pacific Arctic Surface Waters

Creator:: Bryant, Aleesa
Abstract:: The Pacific Arctic is undergoing rapid biogeochemical changes in response to warming air temperatures caused by climate forcing. This is manifesting as changes in seasonal sea ice thickness and sea ice extent, as well as changes in primary production within surface waters. The data and samples analyzed here were collected...

North Pacific Humpback Whales (Megaptera Novaeangliae) in Northern Southeast Alaska: Population Trends, Monitoring, and Management

Creator:: Thurber, Rhianna L.
Abstract:: After the commercial exploitation of humpback whales (Megaptera Novaeangliae) ceased, population trends in the North Pacific increased with the implementation of federal protective legislation. The recovery of the population prompted the National Oceanic and Atmospheric Administration to divide the population into 14 Distinct Population Segments (DPSs) based on discrete geographic...

The Breeding Ecology and Foraging Niche of Aleutian Terns (Onychoprion aleuticus) in the Kodiak Archipelago, Alaska

Creator:: Tengeres, Jill E.
Abstract:: The Aleutian tern (Onychoprion aleuticus) is a species of high conservation concern in Alaska due to large declines at known breeding locations since the 1960s. Due to the small population size and ephemeral behavior of this species on the nesting grounds, there is little basic biological information available and data...

Mining Landsat Time-series Imagery to Understand Spatiotemporal Dynamics of the Urban Landscape: A Perspective from Local Climate Zone Mapping

Creator:: Xu, Chunxue
Abstract:: We live on an Urban Planet. The current unprecedented urbanization is accompanied by intensive land cover transition and demographic shifts from rural to urban livelihoods. Cities serve as cultural, economic, political centers that facilitate wealth creation and innovation of the society, sustaining human from multi-dimensions with large ecological footprints far...

Soil Health and the Response of the Soil Microbial Community to Disturbances across Western North America

Creator:: Kersey, Jordan H.
Abstract:: Temperate coniferous forests, such as those that cover vast areas of the western US and Canada, have evolved to depend on cycles of disturbance for succession of species and overall ecosystem maintenance. Many of these forest systems are managed, often for timber production, where disturbances are of anthropogenic origin and...

Using the National Health and Nutrition Examination Survey to Explore the Relationship between Food Insecurity, Childhood Lead Poisoning, and Attention Deficit Hyperactivity Disorder in Children

Creator:: Sparks, Megan M.
Abstract:: Lead is a ubiquitous environmental toxin known to cause neurological deficits in children. There is no biological need for lead and no safe level of lead in the body has ever been identified. Despite dramatic decline in mean blood lead levels nationwide since the U.S. EPA’s ban on lead-based paint...
