Sustainable Science? Reducing the Carbon Impact of Scientific Mega-Meetings
This article uses 9 years of annual meeting attendance data from the Ecological Society of American and the Association of American Geographers to assess the efficacy of two additional solutions: 1) alternate large national meetings that require significant air travel with smaller regional meetings that do not; and 2) incorporate geography into the meeting location selection process.
Archaeology, Heritage, and Moral Terrains: Two Cases from the Mesa Verde Region
This article applies an environmental justice lens to two archaeological research narratives, one centering on chemical analysis of biomolecular artifact residues and the other on paleohydrology and Pueblo farming.
Validation of a Non-Targeted LC-MS Approach for Identifying Ancient Proteins: Method Development on Bone to Improve Artifact Residue Analysis

Buruli Ulcer Disease and Its Association with Land Cover in Southwestern Ghana
This article presents the first analysis of Buruli ulcer at the village level in southwestern Ghana, where prevalence rates are among the highest globally, and explores fine and medium-scale associations with land cover by comparing patterns both within Buruli ulcer clusters and surrounding landscapes.
Biomass burning drives atmospheric nutrient redistribution within forested peatlands in Borneo
This article quantifies the influence of fire on biogeochemical fluxes of nitrogen, phosphorus, and sulfur in a 12 ha forested peatland in West Kalimantan, Indonesia.
LiDAR Data for Characterizing Linear and Planar Geomorphic Markers in Tectonic Geomorphology
This paper provides a brief review of airborne light detection and ranging (LiDAR) data for characterizing linear and planar geomorphic markers in tectonic geomorphology, including traces of active faults and surface deformation caused by earthquakes. Challenges and opportunities of LiDAR for the study of tectonic geomorphology and coseismic deformation are also discussed.
Improved bore-sight calibration for airborne light detection and ranging using planar patches
This article proposes an improved method for bore-sight calibration based on the principles of symmetry of coordinate offsets and low correlations between bore-sight angles.
Light detection and ranging and hyperspectral data for estimation of forest biomass: a review
This review addresses the status of hyperspectral data, LiDAR data, and the fusion of these two data sources for forest biomass estimation in the last decade.
Comparison of different methods for monitoring glacier changes observed by Landsat images
This paper presents three methods for classifying glacier boundaries, compares the three methods to provide advice on how to choose an appropriate method, and analyzes the relationship between glacier change and the trends of precipitation and temperature.
A rich Internet application for automated detection of road blockage in post-disaster scenarios
This paper presents the development of a rich Internet application for automated detection of road blockage in post-disaster scenarios using volunteered geographic information from OpenStreetMap street centerlines and airborne light detection and ranging (LiDAR) data.
