Horizontal behavior of highly migratory marine species is difficult to decipher because animals are wide-ranging, spend minimal time at the ocean surface, and utilize remote habitats. Satellite telemetry enables researchers to track individual movements, but population level inferences are rare due to data limitations that result from difficulty of capture and sporadic tag reporting. We introdu...

The rising global temperature contributes to a strong impact on urban thermal environment and outdoor thermal comfort. Although the existing satellite telemetry methods are convenient to display geographical information. The detail distributions of 3-dimentional radiation properties of the complex urban environment cannot be estimated accurately due to the low resolution and lack of vertical in...

A setup of satellite ranging based on phsical random sequence is demonstrated, which has absolute security in information transmission because of the random property of the physical sequence. Using true random sequence replacing pesudo random sequence, synchronization technology is vital important for transmitted information demodulation, despreading and decryption. Based on the pricinple of te...

State-space models have recently been shown to effectively model animal movement. In this paper we illustrate how such models can be used to improve our knowledge of animal navigation ability, something which is poorly understood. This work is of great interest when modeling the behavior of animals that are migrating, often over tremendously large distances. We use the term circle of confusion,...

—North American Ospreys (Pandion haliaetus) typically migrate long distances to their wintering grounds in the tropics. Beyond the general distribution of their wintering range (i.e., the Caribbean, South America, and Central America), very little is known about the wintering ecology of these birds. We used satellite telemetry to determine the duration of wintering period, to examine the charac...

William A. Watkins, Woods Hole Oceanographic Institution ~WHOI!, led the development and refinement of the WHOI Radio Whale Tag. The initial tags were developed in the 1960s at WHOI, improved in the 1970s and 1980s by Ocean Applied Research, Inc., and adapted to satellite telemetry in the 1990s by Microwave Telemetry, Inc. Through this entire period, the tag delivery and attachment methods were...

Many wildlife biologists still rely on strip-chart recorders for collecting telemetry information in the field, and modifications that improve the reliability of recording telemetric data and reduce the time required to analyze these data are needed. We observed that 2 identical recorders, which had been geared to run at the same chart speed (5.08 cm/hour), operated at different speeds (4.32 cm...
