Meta-analysis of North American Arctic and boreal aboveground biomass datasets
The North American arctic and boreal regions (ABRs) are rapidly warming and experiencing intensifying disturbances. Accurately quantifying aboveground biomass (AGB) is critical for understanding the impacts of these changes on the carbon cycle and for designing climate change mitigation strategies. Several AGB maps have been developed for the North American ABRs, including recent contributions from National Aeronautics and Space Administration’s …
Tundra recovery post-fire in the Yukon–Kuskokwim Delta, Alaska
The extent of wildfires in tundra ecosystems has dramatically increased since the turn of the 21st century due to climate change and the resulting amplified Arctic warming. We simultaneously studied the recovery of vegetation, subsurface soil moisture, and active layer thickness (ALT) post-fire in the permafrost-underlain uplands of the Yukon–Kuskokwim Delta in southwestern Alaska to understand the interaction between these factors and their pote…
Tundra fire increases the likelihood of methane hotspot formation in the Yukon–Kuskokwim Delta, Alaska, USA
Rapid warming in Arctic tundra may lead to drier soils in summer and greater lightning ignition rates, likely culminating in enhanced wildfire risk. Increased wildfire frequency and intensity leads to greater conversion of permafrost carbon to greenhouse gas emissions. Here, we quantify the effect of recent tundra fires on the creation of methane (CH 4 ) emission hotspots, a fingerprint of the permafrost carbon feedback. We utilized high-resoluti…
Disturbances in North American boreal forest and Arctic tundra
Ecosystems in the North American Arctic-Boreal Zone (ABZ) experience a diverse set of disturbances associated with wildfire, permafrost dynamics, geomorphic processes, insect outbreaks and pathogens, extreme weather events, and human activity. Climate warming in the ABZ is occurring at over twice the rate of the global average, and as a result the extent, frequency, and severity of these disturbances are increasing rapidly. Disturbances in the AB…
An overview of ABoVE airborne campaign data acquisitions and science opportunities
The 2017 Arctic Boreal Vulnerability Experiment Airborne Campaign (AAC) was one of the largest, most complex airborne science experiments conducted by NASA’s Earth Science Division. Between April and November, the AAC involved ten aircraft in more than 200 science flights that surveyed over 4 million km 2 in Alaska and northwestern Canada. Many flights were coordinated with same-day ground-based measurements to link process-level studies with geo…
More frequent burning increases vulnerability of Alaskan boreal black spruce forests
Much recent research has investigated the effects of burning on mature black spruce ( Picea mariana ) forests in interior Alaska, however little research has focused on how frequent reburning affects soil organic layer (SOL) vulnerability in these ecosystems. We compared organic soil layer characteristics in black spruce stands that burned after two fire-free intervals (FFI), including an intermediate-interval (37–52 years) and a more typical lon…
Making survey results easy to report to consumers
Making Survey Results Easy to Report to Consumers
OBJECTIVES: CAHPS is designed to report information about health care quality from the consumer perspective. Enrollees are surveyed about their experiences with their health plan and medical care, and results are reported to other consumers choosing among health plans. Based on survey instruments designed to elicit reliable and valid information about health plan experiences from plan enrollees, the aim of the CAHPS team was to design a series of…
Studies on the hyperactive child-VII
Twenty hyperactive children were compared with neurotic and normal controls. Hyperactive children showed significantly more neurological abnormalities, principally an excess of soft signs reflecting sensorimotor incoordination, but no differences in major neurological signs, EEG abnormalities, or medical history. It is hypothesized that chronic hyperactivity in children of normal IQ is a disorder discrete from neurosis and is probably an organic …
