What is the time response (tau) of a thermistor? The time constant of a thermistor, also referred to as time response or tau (τ), is conventionally defined as the amount of time for the signal measured by the thermistor to increase to 63.2% of its final value (Emery and Thomson, 2004). In other words, it is the e-folding time: 63.2% … Read More about Thermistor time response: what is it and why is it important?
About pyRSKtools pyRSKtools is RBR’s open source Python toolbox for reading, post-processing, visualizing, and exporting RBR logger data. Users may plot data as a time series or as depth profiles using tailored plotting utilities. In addition, you can easily plot time-depth heat maps to visualize transects or moored profiler data. A full suite of data post-processing functionality, such as methods … Read More about pyRSKtools: Improved oceanographic data processing with Python
The Argo program is the largest ocean climate monitoring system in the world, providing continuous observations of key ocean parameters through a global array of autonomous profiling floats. In 2018, RBR joined the program’s pilot project to diversify the floats’ CTD sensor technology, which is crucial to avoiding single points of failure. RBR introduced the RBRargo3 C.T.D as a low-power, high-accuracy alternative that is … Read More about RBR provides CTDs and sensors for the Argo program

Speed of sound in waterWhat is speed of sound in water and why do we measure it? Sound-speed in water is a quantification of how fast sounds travel in water. The speed of sound in water depends on temperature, salinity, and pressure, and is therefore not uniform throughout different water environments. In the oceans, the speed of sound varies between 1450m/s … Read More about All about speed of sound in water – what it is, how it’s measured, and why we care
