Marine Mammal Science 27 3 : E—E It all depends on the length of your menstrual cycle … simple, right? The model assumes that each GVP start is independent given the RL rms ; therefore residuals were checked and no temporal or spatial autocorrelation was evident.
The first consisted of acoustic detection archives derived from range hydrophone data. Estimated probability of a GVP start as a function of maximum RL rms in a 30 minute segment on a given hydrophone on the logit left plot and linear right plot scale.
A total of 18 acoustic analysis points were distributed over the range in six rows of three. Other, more common, pregnancy symptoms to watch out for will manifest closer to six or seven weeks' gestation, and include nausea, vomiting and severe fatigue. These detection spectra were used to identify both groups of vocalizing animals and sonar pings as received on individual range hydrophones during actual multi-ship MFA sonar operations.
An automated procedure was used to associate clicks into click trains, and click trains associated across hydrophones to identify Group Vocal Periods GVP.
This estimate dipped to 1. A total of GVP starts were identified in data collected from 91 hydrophones in the segments before the multi-ship exercise began. Weinberg H, Keenan R Gaussian ray bundles for modeling high frequency propagation loss under shallow-water conditions. Tyack et al.
You can get pregnant while on your period, but the chances are very slim. The received level of a sonar ping at each hydrophone was calculated using the predicted propagation loss along the closest radial axis.
Operational Navy security precluded direct recording of the hydrophones during operations. We have derived an empirical risk function for beaked whales that relates the probability of behavioral change to the RL rms from MFA sonar.
