When the earth doesn’t stop shaking: How experiences over time influenced information needs, communication, and interpretation of aftershock information during the Canterbury Earthquake Sequence, New Zealand
The Canterbury Earthquake Sequence (CES) began with the Darfield earthquake on 4 September 2010. Continual large and small aftershocks since that time have meant communities have cycled through repeated periods of impact, response and recovery. Scientific communication about aftershocks during such a prolonged sequence has faced distinct...
Becker, Julia S.; Potter, Sally H.; McBride, Sara; Wein, Anne M.; Paton, Douglas Modeling riparian restoration impacts on the hydrologic cycle at the Babacomari Ranch, SE Arizona, USA
This paper describes coupling field experiments with surface and groundwater modeling to investigate rangelands of SE Arizona, USA using erosion-control structures to augment shallow and deep aquifer recharge. We collected field data to describe the physical and hydrological properties before and after gabions (caged riprap) were installed in an...
Norman, Laura M.; Callegary, James B.; Lacher, Laurel; Wilson, Natalie R.; Fandel, Chloé; Forbes, Brandon T.; Swetnam, Tyson A bibliometric profile of the Remote Sensing Open Access Journal published by MDPI between 2009 and 2018
Remote Sensing Open Access Journal (RS OAJ) is an international leading journal in the field of remote sensing science and technology. It was first published in the year 2009 and is currently celebrating tenth year of publications. In this research, a bibliometric analysis of RS OAJ was conducted based on 5588 articles published during the 10-year...

Hudson-Doyle, E.E.; McBride, Sara; Wein, Anne M.; Becker, Julia S.; Potter, Sally H.; Hudson-Doyle, E.E. Population vulnerability to tsunami hazards informed by previous and projected disasters: A case study of American Samoa
Population vulnerability from tsunamis is a function of the number and location of individuals in hazard zones and their ability to reach safety before wave arrival. Previous tsunami disasters can provide insight on likely evacuation behavior, but post-disaster assessments have not been used extensively in evacuation modeling. We demonstrate the...
Wood, Nathan J.; Jones, Jeanne M.; Yamazaki, Yoshiki; Cheung, Kwok-Fai; Brown, Jacinta; Jones, Jamie; Abdollahian, Nina Nominal 30-m cropland extent map of continental Africa by integrating pixel-based and object-based algorithms using Sentinel-2 and Landsat-8 Data on Google Earth Engine
A satellite-derived cropland extent map at high spatial resolution (30-m or better) is a must for food and water security analysis. Precise and accurate global cropland extent maps, indicating cropland and non-cropland areas, are starting points to develop higher-level products such as crop watering methods (irrigated or rainfed), cropping...
Xiong, Jun N.; Thenkabail, Prasad S.; James C. Tilton; Gumma, Murali Krishna; Teluguntla, Pardhasaradhi G.; Oliphant, Adam; Congalton, Russell G.; Yadav, Kamini; Gorelick, Noel MODIS phenology-derived, multi-year distribution of conterminous U.S. crop types
Innovative, open, and rapid methods to map crop types over large areas are needed for long-term cropland monitoring. We developed two novel and automated decision tree classification approaches to map crop types across the conterminous United States (U.S.) using MODIS 250 m resolution data: 1) generalized, and 2) year-specific...
Massey, Richard; Sankey, T.T; Congalton, Russ; Yadav, Kamini; Thenkabail, Prasad; Ozdogan, Mutlu; Meador, Sanchez Grasslands
Key findings:Total grassland carbon stocks in the conterminous United States, estimated to be about 7.4 petagrams of carbon (Pg C) in 2005, are projected to increase to about 8.2 Pg C by 2050. Although U.S. grasslands are expected to remain carbon sinks over this period, the uptake rate is projected to decline by about half. In the U.S. Great...

Accuracies achieved in classifying five leading world crop types and their growth stages using optimal Earth Observing-1 Hyperion hyperspectral narrowbands on Google Earth Engine
As the global population increases, we face increasing demand for food and nutrition. Remote sensing can help monitor food availability to assess global food security rapidly and accurately enough to inform decision-making. However, advances in remote sensing technology are still often limited to multispectral broadband sensors. Although these...

Crop water productivity (CWP) is the ratio of accumulated crop biomass or yield (Y) to the water utilized to produce it, which is typically estimated using transpiration (ETC). CWP is an important metric to test and monitor water-saving strategies in agroecosystems across the globe. Red and near-infrared broadbands have been used to estimate CWP,...
