Abstract On the Washington and Oregon coast of the NE Pacific Ocean from 2008-2015, we found that juveniles represented 83% of Northern Fulmars that were beached. In comparison to older birds, juveniles averaged more mass and pieces of plastic in stomachs. This reflected relatively larger plastic loads in the cranial stomach section, the proventriculus, which we found was associated with relatively large accumulations in the caudal stomach section, the ventriculus. We estimate that the proven [...] |
Spatial Relation between Wind Stress and Storm Surge during Hurricanes Laura and Delta in 2020by
Shih-Ang Hsu
Abstract Spatial relation between wind stress and storm surge during two hurricanes in 2020 is investigated. It is found that, during Laura’s landfall, the area inside of 65 knots (34 m s -1) isotach or line of equal wind speed can produce up to 18 ft (5.5 m) inundation and during Delta, the area inside of 50 knots (26 m s -1) up to 11 ft (3.3 m) high water level above the ground. The tropical cyclone (TC) surface analysis near landfall by the Reg [...] |

Abstract The coronavirus disease 2019 (COVID-19) is a global crisis spreading to all countries. This study explains and documents the first-order effects of the new coronavirus on the urban water cycle. Urban water systems play an important role in public health because people rely so heavily on water services. Findings address short- and long-term changes in climate variables; availability and accessibility of clean water to prevent and control the spread of coronavirus in water-scarce citie [...] |
Reconstruction of Anthropogenic Land-Cover Change for Middle America, 1500 CEAbstract This project demonstrates how to use existing syntheses of many decades of historical social science research to produce empirically derived land-use maps in a GIS for large regions for a specific target year at a resolution appropriate to the calibration of existing anthropogenic land-cover change (ALCC) models. Disagreement among the outputs of various ALCC models results from differing estimates of population and assumptions about how much food a given population requires and the [...] |
Analysis of Surface Water Areal changes using Remote Sensing Databy

Abstract Inland water bodies are crucial for supporting human life in various parts of the world. Therefore, it is essential to accurately monitor its spatiotemporal variations for better water management. The main objective of this study is to investigate the application of remote sensing data for quantifying the surface area changes and the impact of climatological variabilities over Lakes Mead and Chapala. Historical time series of monthly surface area dynamics were developed using Landsat [...] |
Normalized Difference Vegetative Index-related Assessment for Climate Change Impact on Indigenous Communities from High Resolution IKONOS Satellite Imagery in West PapuaAbstract High-resolution satellite imagery permits acquisition of critical data to observe climate-change and environmental impact on conflict-impacted indigenous communities with co-existing socio-economic factors, often within unstable regimes. Conflict may prevent direct access in remote regions to validate civilian conflict actor evidence. In such cases use of remote sensing tools, techniques, and data are extremely important. Software-based imagery assessment can quantify radiometrically [...] |
Correction of Sunglint Effects in High Spatial Resolution Hyperspectral Imagery Using SWIR or NIR Bands and Taking Account of Spectral Variation of Refractive Index of Waterby

Rong-Rong Li
Abstract Passive high spatial resolution hyperspectral and multispectral imaging systems in the solar spectral region from aircraft and satellite platforms are being increasingly used for remote sensing of coastal waters and inland lakes. However, the remotely sensed data are often contaminated by the specular reflection of solar radiation at the air/water interface. Thus, the effects of sunglint need to be corrected. The purpose of sunglint correction is to remove the undesired specular refl [...] |
