Comments on Oceanographic Instrument Development

Oceanographic Sensor System Development

hen the Submarine Technology Department (now the National Security Technology Department) was formed in 1977, it launched an evolution, if not a revolution, in the design of oceanographic sensor systems at APL. This drove rapid advances in ocean sensor systems engineering and technology to support a better understanding of upper ocean dynamics. In this article we provide a brief review of engin...

Principles of Oceanographic Instrument Systems -- Sensors and Measurements

A system is completely defined by its input and output specifications. For example, an instrument system might measure, record, and display a physical variable. The exact way this is done is unimportant as long as the specifications are met. We often deal with components of an instrument system such as sensors, amplifiers, or recorders but in general these are not complete and their characteris...

Principles of Oceanographic Instrument Systems -- Sensors and Measurements

For some purposes it is less important to measure the physical variables in the environment than to detect variations in them or to determine the pattern of those variations. The search for salt fingers illustrates this case. One ocean mixing process contending for the role of a major global process in 1972 was double diffusion, in particular salt fingering. But although there was indirect evid...

Development and Validation of Successful Aging Instrument

Objectives: Successful aging is an interdisciplinary concept. Despite the great body of literature on successful aging, few studies have focused on its subjective and multidimensional measurements. Thus, the present study aimed to develop an instrument to measure self-perceived successful aging. Methods: We used a mixed method approach. The successful aging dimensions were explored through an ...
