We have expertise in obtaining research data in the sea using sound, so-called acoustic data. By placing hydrophones, we capture sounds in the sea. We can distinguish between different sound sources, …

Ocean currents and smaller movements in the water can also be researched using sound. Sound can not only be used as a tool to measure conditions in the sea, but also to collect data from installations …

Data product: Acoustic travel times, depth averaged sound converted to mean ocean Passive acoustic data spectrogram.

Sounds in the ocean There are many sources of sound in the ocean, both natural and man-made. Marine mammals, such as the whale, communicate with unique signals underwater. Earthquakes …

Each acoustic recording covered 130 s with sampling rate 1000Hz. 10-, 50- and 90- percentiles of sound pressure and power were calculated for each reception using 50 % overlapping Hanning window with …

The tomography system will measure average sound speed in different depths of the water column. The data from the first array will be recovered next summer and be converted to a year-long record of …

Sound is widely used for remote sensing of the ocean on small scales (e.g., acoustic Doppler current profilers), but acoustical measurements have been underexploited in regional and global ocean …

Each acoustic recording covered 130 s with sampling rate 1000Hz. 10-, 50- and 90- percentiles of sound pressure and power were calculated for each reception using 50 % overlapping Hanning window with …

“Light, sound, and the changing Arctic Ocean” The Arctic Ocean is changing rapidly, but observing these changes beneath its ice cover is extremely difficult.

The data were were obtained over 362 days every 3 hours from Aug 2010 - Jul 2011, and from Sep 2011 - Jul 2012. 0-, 50- and 90- percentiles of the sound pressure and power for each frequency (0 …
