mean_absorption

This function is used to calculate the mean absorption in salt water over a frequency range.

High-resolution movement-sensor tags typically include accelerometers
to measure body posture and sudden movements or changes in speed,
magnetometers to measure direction of travel, and pressure sensors
to measure dive depth in aquatic or marine animals. The sensors in these tags usually sample many times per second. Some tags include sensors for speed, turning rate (gyroscopes), and sound. This package provides software tools to facilitate calibration, processing, and analysis of such data. Tools are provided for: data import/export;
calibration (from raw data to calibrated data in scientific units);
visualization (for example, multi-panel time-series plots);
data processing (such as event detection, calculation of derived metrics like jerk and
dynamic acceleration, dive detection, and dive parameter calculation); and statistical analysis (for example, track reconstruction, a rotation test, and Mahalanobis distance analysis).

mean_absorption function

<dl><dt>freq</dt>
<dd>Specifies the frequency range, freq = c(fmin, fmax) in Hz. For a single frequency, use a scalar value for freq.</dd>
<dt>r</dt>
<dd>The path (slant) length in metres.</dd>
<dt>depth</dt>
<dd>The depths covered by the path. This can be a single value for a horizontal path or a two component vector i.e., depth = c(dmax, dmin) for a path that extends between two depths.</dd>
<dt>Ttab</dt>
<dd>(optional) The temperature (a scalar) in degrees C or specifies a temperature profile Ttab = c(depth, tempr) where depth and tempr are equal-sized column vectors. Default value is an isothermal profile of 13 degrees.</dd></dl>
