Preparation And Mitigation Efforts For Volcanic Hazards In The Pacific Northwest, Nick Griffith 2020 Western Oregon University

Preparation And Mitigation Efforts For Volcanic Hazards In The Pacific Northwest, Nick Griffith

Academic Excellence Showcase Proceedings

Volcanic eruptions represent one of the most serious geologic hazards facing the Pacific Northwest, with several volcanoes located within striking distance of the most highly populated areas in the region. This paper describes the hazards associated with these eruptive centers and discusses the best practices for preparing communities for potential eruptions and mitigating volcanic hazards. This study is based on data collected by the United States Geological Survey (USGS) on volcanic systems such as Mt. St. Helens and Mt. Rainier. Many other scientific organizations have studied analogous volcanic systems beyond the Pacific Northwest, such as the volcanically active island of ...

A Statistical Impulse Response Model Based On Empirical Characterization Of Wireless Underground Channel, Abdul Salam, Mehmet C. Vuran, Suat Irmak 2020 Purdue University

A Statistical Impulse Response Model Based On Empirical Characterization Of Wireless Underground Channel, Abdul Salam, Mehmet C. Vuran, Suat Irmak

Faculty Publications

Wireless underground sensor networks (WUSNs) are becoming ubiquitous in many areas. The design of robust systems requires extensive understanding of the underground (UG) channel characteristics. In this paper, an UG channel impulse response is modeled and validated via extensive experiments in indoor and field testbed settings. The three distinct types of soils are selected with sand and clay contents ranging from $13\%$ to $86\%$ and $3\%$ to $32\%$, respectively. The impacts of changes in soil texture and soil moisture are investigated with more than $1,200$ measurements in a novel UG testbed that allows flexibility in soil moisture control. Moreover ...


High Frequencies Of Theropod Bite Marks Provide Evidence For Feeding, Scavenging, And Possible Cannibalism In A Stressed Late Jurassic Ecosystem, Stephanie K. Drumheller, Julia B. McHugh, Miriam Kane, Anja Riedel, Domenic D'Amore 2020 Daemen College

High Frequencies Of Theropod Bite Marks Provide Evidence For Feeding, Scavenging, And Possible Cannibalism In A Stressed Late Jurassic Ecosystem, Stephanie K. Drumheller, Julia B. Mchugh, Miriam Kane, Anja Riedel, Domenic D'Amore

Faculty Articles

Bite marks provide direct evidence for trophic interactions and competition in the fossil record. However, variations in paleoecological dynamics, such as trophic relationships, feeding behavior, and food availability, govern the frequency of these traces. Theropod bite marks are particularly rare, suggesting that members of this clade might not often focus on bone as a resource, instead preferentially targeting softer tissues. Here, we present an unusually large sample of theropod bite marks from the Upper Jurassic Mygatt-Moore Quarry (MMQ). We surveyed 2,368 vertebrate fossils from MMQ in this analysis, with 684 specimens (28.885% of the sample) preserving at least ...
