Coastal environments are characterized by complex feedbacks between flow, sediment transport, and morphology, often resulting in the formation of nearshore sandbars. In many locations, such as Hasaki (Japan), the Netherlands, and the Columbia River Littoral Cell (CRLC, USA), these sandbars exhibit a net offshore migration (NOM) cycle whereby these features...
Sediment spectral reflectance measurements were generated aboard the JOIDES Resolution during Ocean Drilling Program Leg 162 shipboard operations. The large size of the raw data set (over 1.3 gigabytes) and limited computer hard disk storage space precluded detailed analysis of the data at sea, although broad band averages were used...
Plankton tows from the northern California Current constrain biological and physical
influences on living planktonic foraminifera. In this region, the dominant factors controlling the
size and distribution of symbiotic and asymbiotic species are light and food. Food decreases offshore.
Light, needed for symbiont photosynthesis, increases offshore as water turbidity lessens....
Multiple paleoceanographic proxies in a zonal transect across the California Current
near 42°N record modern and last glacial maximum (LGM) thermal and nutrient gradients. The
offshore thermal gradient, derived from foraminiferal species assemblages and oxygen isotope data,
was similar at the LGM to that at present (warmer offshore), but average...
Diffuse reflectance records from Feni Drift in the North Atlantic faithfully record sediment percent carbonate. A high-resolution, reflectance-based age model for these sediments derived from an orbitally tuned age model for western equatorial Atlantic, Ceara Rise sediments was generated by spectral frequency mapping. Power spectra of the Feni Drift record...
To guide the future development of CO₂-atmospheric inversion modeling systems, we analyzed the errors arising from prior information about terrestrial ecosystem fluxes. We compared the surface fluxes calculated by a process-based terrestrial ecosystem model with daily averages of CO₂ flux measurements at 156 sites across the world in the FLUXNET...
Fennema and Sherman (1976) defined math anxiety as "feelings of anxiety, dread, nervousness, and associated bodily symptoms related to doing mathematics" (p. 326). The longitudinal impact that math anxiety has on adolescent students can include their experiencing reduced math achievement, avoiding majors that involve large amounts of math, and choosing...
The goal of this project is to better characterize particle movement in a multi-channel fluidized bed. Fluidized beds are commonly used for heat transfer with the rapid fluidization and homogeneous heat distribution. By characterizing this particle flow, it would allow for an improved understanding of the heat transfer mechanisms within...
The COVID-19 pandemic has disrupted life for populations all over the world. One population that has been uniquely impacted by the pandemic is the student-athlete population. Over the last two years, universities took safety precautions by first sending students home and moving teaching and learning to a remote format and...
Each year, numerous people attend cultural events in the United States, be they large celebrations such as New Orleans’ Mardi Gras or one of many numerous Cinco de Mayo festivals throughout the country or smaller, more specialized events. Many times, the cultural aspects take a backseat to profits, which leads...
