New study calculates retreat of glacier edges in Alaska’s Kenai Fjords National Park
A new study measured 38 years of change for glaciers in Kenai Fjords National Park, which lies south of Anchorage, and found that 13 of 19 glaciers show substantial retreat, four are relatively stable, and two have advanced. It also finds trends in which glacier types are disappearing fastest.
Green earplugs
Cars, trains, planes: For two thirds of the European population, traffic noise is part of everyday life. However, the right environment can have a major impact on this nuisance, as Empa researchers have found out. Green spaces in urban areas help to make road and railroad noise less of a nuisance. Only in the case of aircraft noise does this seem counterproductive: the greener the surroundings, the more disturbing the aircraft noise.
The rise of ‘Zoom Towns’ in the rural west
COVID-19 has expedited a trend of migration into western gateway communities—remote workers are fleeing cities to ride out the pandemic. A new study using data from 2018 found that growing populations caused urgent planning pressures, and officials felt unprepared to respond to and prepare for problems associated with rapid growth.
National Park Service Scientists: Does Aircraft Noise Make Birds More Vocal?
National Park Service scientists analyzed nearly 1 million 10-second audio recording samples from national parks across the country and discovered a small increase in bird sound detection when an aircraft sound is also detected. During the 178th ASA Meeting, Kurt Fristrup will present the findings and how human responses to noise might be studied.
