ACOUSTIC SURVEY [3 records]

English

Subject field(s)
  • Acoustics (Physics)
  • Hydrology and Hydrography
  • Commercial Fishing
CONT

An acoustic survey is a method of gathering information on the abundance of a fish species using echo sounders. Sound is a form of energy which travels farther and faster underwater than in the air. So using the distance a sound travels and the record it makes when it bounces off of something underwater can tell a researcher a good deal about the creatures passing by underwater.

OBS

In an acoustic survey, a transducer emits a pulse of sound. The transducer can be either fixed or mounted on a moving vessel. The sound moves through the water until it bumps into something, such as a fish, and part of its energy is reflected back to the transducer. Another device, called an echo sounder, amplifies the returned energy and sends it to a recorder where it registers as a mark.

On mène deux types de relevés acoustiques dans le parc : stationnaires et mobiles. On utilise dans les deux cas un appareil d'enregistrement pour enregistrer les cris des chauves-souris à la fréquence des ultrasons propres à chaque espèce.

Subject field(s)
  • Geophysics
  • Oil and Natural Gas Extraction
DEF

A method that measures the time required for sound impulses to travel through a given length of rock.

OBS

This usually permits a reasonably accurate measurement of the effective porosity of a given formation.

OBS

The record resulting from this process is called "acoustic log."

CONT

La diagraphie acoustique est une méthode d'investigation verticale des terrains sondés, complémentaire et peu coûteuse, par rapport aux carottages. Elle renseigne sur la densité des formations, mais aussi sur les propriétés mécaniques, structurales de la roche.

OBS

diagraphie acoustique : terme en usage à Ressources naturelles Canada - Secteur des sciences de la Terre.
