Integrating Research into Conservation: Using Satellite Telemetry and Population Monitoring to Inform the Management of Hawksbill Turtles in Brazil
… for the health of marine biodiversity. Utilizing satellite telemetry and population monitoring, key demographic parameters and spatial ecology of nesting hawksbill turtles were investigated. The utilization distribution by tracked turtles overlapped with Marine Protected Areas (MPAs) and the …

Movements and home range size of bald eagles from Glacier Bay National Park and Preserve, Alaska: with an analysis of satellite telemetry
… Alaska. I estimated locations by homing and satellite telemetry. During the breeding season, the distances adult eagles moved from successful, unsuccessful, and mixed-success nests were not significantly different (£ = 0.148). Regardless of nest success, the proportion of adult eagle …

Spatial, temporal and within-species variation in the foraging ecology of a marine predator across a dynamic seascape
… time using stable isotope analysis and animal satellite telemetry. I used a long-term dataset (1990 – 2013) of ringed seal muscle (n = 630) and liver (n = 558) samples, as well as satellite telemetry data (1999-2013; n= 132) collected from seven locations across the Arctic of varying latitude …

Machine learning for time series anomaly detection
… sensors. The data, obtained from satellite telemetry signals, were used to train models to forecast a signal based on its historic patterns. When the prediction passed a dynamic error threshold, then that point was flagged as anomalous. I used multiple models such as Long …

Environmental Factors Influencing Spring Migration Chronology of Lesser Scaup (Aythya affinis)
… temperature, precipitation and ice cover. I used satellite telemetry data, waterfowl survey data and corresponding weather data to evaluate competing models that explained variation in timing and rate of migration by lesser scaup. Timing of spring migration occurred earlier and faster when lesser …

Design and Validation of Hardware-in-the-Loop Testbed for Proximity Operations Payloads
… can be seen through the implementation of actual satellite telemetry with rendezvous and docking missions, the testbed performance, and the results of that experiment.</p>

Nesting Ecology of Hawksbill Sea Turtles (Eretmochelys imbricata) on Utila, Honduras
… on the island of Utila were elucidated using satellite telemetry, beach profiling, vegetation surveys, beach monitoring, and nest temperature profiles. We affixed satellite transmitters to two nesting hawksbills, and found the turtles migrated to different countries. One turtle traveled 403 km …

Migratory Ecology of Sea Turtles
… method for identifying behavioral changes in satellite telemetry based on Change-Point Analysis (CPA). Subsequently, I applied it to analyze the post-nesting leatherback turtles tracked from the iSimangaliso Wetland Park, South Africa. Half (n = 8) of the turtles tracked migrated to foraging …

Frequency Estimation of Linear FM Scatterometer Pulses Received by the SeaWinds Calibration Ground Station
… instrument operation and to eliminate error in satellite telemetry and in data products generated from processing SeaWinds data. Sources of instrument error include uncertainties in transmitted power, pulse timing, and carrier frequency drift. Identifying these errors prevents their propagation …

Conserving widely distributed wildlife species in an African savanna: parks, cattle-grazing and community-managed areas
… Examination of seasonal home range use using satellite telemetry showed that female Kori are sedentary in central Botswana,with strong site-fidelity to dry-season home ranges associated with resource-rich pan habitats; the species appears sensitive to localised habitat conditions and resource …

Movements, dive behavior and trophic ecology of leatherback turtles (Dermochelys coriacea) in the northwest Atlantic
… throughout much of their range. I used satellite telemetry to monitor movements and dive behavior of nine adult and eleven sub-adult leatherbacks captured off Massachusetts, USA, and tracked throughout the NW Atlantic. Leatherback movements and environmental associations varied by …

Collaborative competition for crowdsourcing spaceflight software and STEM education using SPHERES Zero Robotics
… programming competition. The robots are nanosatellites called SPHERES - an experimental testbed to test navigation, formation flight and control algorithms - onboard the International Space Station (ISS). Zero Robotics allows students to access SPHERES through a web-based interface and the …

Studies of the Annual Cycle of the Swallow-Tailed Kite (<em>Elanoides forficatus</em>): Migration, Habitat Use, and Parasites
… stopover sites. To examine this prediction, 29 satellite-tracked kites from the U.S. were monitored to quantify migration rates and movements. Swallow-tailed Kites do not show significant stopover on Cuba. However, as predicted, kites slowed down and moved around the Yucatan more than any other …

Space radiation environment impacts on high power amplifiers and solar cells on-board geostationary communications satellites
Communications satellite operators maintain archives of component telemetry to monitor system function. Operators generally do not typically use the telemetry data for scientific analysis of the space radiation environment effects on component anomalies or performance. We partnered with four …

Post-release movements of translocated White-tailed eagles (Haliaeetus albicilla) during the first year of juvenile dispersal
… movements of translocated WTE, using satellite telemetry, from release, up until the end of their first year. Data was utilised from nine birds from two groups during analysis (Cohort 1 and Cohort 2). The aim of this research was to increase our understanding of what the birds did …

Migratory Ecology and Movement Patterns of Mid-Continent and Eastern Sandhill Cranes
Sandhill cranes (Antigone canadensis) are long-lived birds with relatively low recruitment rates, making accurate knowledge of abundance and distribution critical for well-informed harvest management. Minnesota is one of few states containing portions of 2 different breeding populations of greater …
