Acoustic detection and quantification of benthic egg beds of the squid Loligo opalescens in Monterey Bay, California.
The squid Loligo opalescens is a key species in the nearshore pelagic community of California, supporting the most valuable state marine fishery, yet the stock biomass is unknown. In southern Monterey Bay, extensive beds occur on a flat, sandy bottom, water depths 20-60 m, thus sidescan sonar is a prima-facie candidate for use in rapid, synoptic, and noninvasive surveying. The present study des...
متن کاملThe detectability of baryonic acoustic oscillations in future galaxy surveys
We assess the detectability of baryonic acoustic oscillations (BAO) in the power spectrum of galaxies using ultra large volume N-body simulations of the hierarchical clustering of dark matter and semi-analytical modelling of galaxy formation. A step-bystep illustration is given of the various effects (nonlinear fluctuation growth, peculiar motions, nonlinear and scale dependent bias) which syst...
متن کاملContact with Squid Egg Capsules Increases Agonistic Behavior in Male Squid (Loligo pealei).
Agonistic (aggressive) behavior is costly (I). For this reason. males should tight only when it will increase their reproductive fitness. In some species, the last male to mate with a female before she oviposits sires most of the offspring (2). If Loligo pealei has a similar system of sperm precedence. a male should drive away nearby males when females are about to lay their eggs. In L. pealei....
متن کاملAcoustic and Egg Analysis of Pressed Phonation
Pressed phonation ("rikimi" in Japanese) is a voice quality that carries important paralinguistic information of expressivity in the emotional or attitudinal states of the speaker. Analysis of pressed voice samples extracted from natural conversational speech firstly shows that irregularity in periodicity (such as in vocal fry and harsh voices) is a common but not a strictly determinant feature...
متن کاملAcoustic Detection of Flooding in Absorption Columns and Trickle Beds
In countercurrent flow absorption columns and trickle beds, if either the liquid or gas flow is too high the column becomes flooded with the liquid. Flooding is accompanied by a dramatic increase in pressure, resulting in inefficient operation and potential damage to equipment. To optimize efficiency, however, it is desirable to operate as close to flooding as possible. This article discusses t...
