Alaska permafrost characterization: Geophysical and related field data collected from 2019-2020 Alaska permafrost characterization: Geophysical and related field data collected from 2019-2020

Geophysical measurements were collected by the U.S. Geological Survey (USGS) at two sites in Interior Alaska in 2019 and 2020 for the purposes of imaging permafrost structure and quantifying variations in subsurface moisture content in relation to thaw features. In September 2019, electrical resistivity tomography (ERT) and downhole nuclear magnetic resonance (NMR) data were used to...

Interferometric synthetic aperture radar data from 2020 for landslides at Barry Arm Fjord, Alaska Interferometric synthetic aperture radar data from 2020 for landslides at Barry Arm Fjord, Alaska

Subaerial landslides at the head of Barry Arm Fjord in southern Alaska could generate tsunamis (if they rapidly failed into the Fjord) and are therefore a potential threat to people, marine interests, and infrastructure throughout the Prince William Sound region. Knowledge of ongoing landslide movement is essential to understanding the threat posed by the landslides. Because of the...

Stable isotope dynamics of herbivorous reef fishes and their ectoparasites: 2012, 2013, 2018 Stable isotope dynamics of herbivorous reef fishes and their ectoparasites: 2012, 2013, 2018

Acanthurid surgeonfishes are an abundant and diverse group of herbivorous fishes on coral reefs. While their contribution to trophic linkages and dynamics in coral reef systems has received considerable attention, the role of linkages involving their parasites has not. As both consumers of fish tissue and prey to microcarnivores, external parasites can play a significant role in trophic...
