This mechanism could explain the Bloop's wide detection range and distinct acoustic signature. [7] As oceanographer Yunbo Xie explains, the alteration of waveforms from a detected sound "can also be caused by so-called angular frequency dependent radiation patterns associated with antisymmetric mode motion of the ice cover."

A spectrogram of Bloop. Bloop is the name given to an ultra-low-frequency and extremely powerful underwater sound detected by the U.S. National Oceanic and Atmospheric Administration (NOAA) in 1997. The sound is consistent with the noises generated by icequakes in large icebergs, or large icebergs scraping the ocean floor. [3]
In science, Brownian noise, also known as Brown noise or red noise, is the type of signal noise produced by Brownian motion, hence its alternative name of random walk noise. The term "Brown noise" does not come from the color , but after Robert Brown , who documented the erratic motion for multiple types of inanimate particles in water.
The total range of the species is roughly 380 000 km 2. [10] In the 1980s, ... The mating call of the Ludwig's bustard is a deep ‘bloop’ noise. [12]
For example, with a white noise audio signal, the range of frequencies between 40 Hz and 60 Hz contains the same amount of sound power as the range between 400 Hz and 420 Hz, since both intervals are 20 Hz wide. Note that spectra are often plotted with a logarithmic frequency axis rather than a linear one, in which case equal physical widths on ...
Three employees at a Maryland Cracker Barrel have reportedly been dismissed after staff refused to seat a group of students with special needs on Dec. 3
An active Brownian particle (ABP) is a model of self-propelled motion in a dissipative environment. [1] [2] [3] It is a nonequilibrium generalization of a Brownian particle.The self-propulsion results from a force that acts on the particle's center of mass and points in the direction of an intrinsic body axis (the particle orientation).
