Seasonal and diel patterns in sedimentary flux of krill fecal pellets recorded by an echo sounder
echo sounder Seasonal diel patterns
2014/4/2
We used a moored upward-facing 200 kHz echo sounder to address sedimentation of fecal pellets (FPs) from
dielly migrating Meganyctiphanes norvegica. The echo sounder was located on the bottom at 150 ...
Measuring Dynamic Heights with Inverted Echo Sounders：Results from MODE
Inverted Echo Sounders Measuring Dynamic Heights Results from MODE
2009/3/7
Inverted Echo Sounders (IES) were deployed during MODE at seven ocean bottom stations to acoustically monitor depth variations of the main thermocline. The IES transmits pulses of 10 kHZ sound and rec...
Observations of Inertia-Gravity Waves in the Atlantic from Inverted Echo Sounders during FGGE
Inertia-Gravity Waves Inverted Echo Sounders
2009/2/10
The study is based on observations from inverted echo sounders anchored near the equator in the western Atlantic Ocean. It appears to be a good method of detecting inertia-gravity waves with large ver...
Measurements with an Automatically Recording Inverted Echo Sounder; ARIES and the Bubble Clouds
Automatically Recording Inverted Echo Sounder Bubble Clouds ARIES
2009/1/12
We report here analysis of the first observations with a new instrument, ARIES, designed to record the acoustic backscatter from bubble clouds at several levels below the surface of the ocean. The ins...
Observing Groups of Solitary Internal Waves and Turbulence with BATFISH and Echo-Sounder
Solitary Internal Waves Echo-Sounder BATFISH
2009/1/4
Acoustic backscatter from a 200 kHz echo-sounder and temperature fine-structure from a towed CTD (BAT-FISH) am compared prior to and during the passage of a group of large-amplitude internal waves on ...
