OPUS  (the Open Portal to Underwater Soundscapes)

To share these underwater soundscapes with you, we developed (and keep working on) OPUS, the Open Portal to Underwater Soundscapes.  The portal will give access to HAFOS, FRAM and PALAOA recordings by audio and synchronized spectral visualizations at staggered temporal resolution to enjoy underwater (night-)life.  On the 8th of February 2022 we launched a first version of OPUS, exhibiting some of our recorders in the Antarctic and Arctic.
