Undersea fieldwork

 

I had to challenge my earth-bound senses and immerse myself below the surface of the sea. How easy it is, just letting your body move with the waves rolling into shore — and what you will find is that this symbiosis of sea and shore is full of wonders.


These videos are part of a multisensory fieldwork comprising observations through the changing seasons 2017-2020: With expeditions taking place along the Fjord City’s urban foreshore, the inner Oslofjord urban sea areas and the islands of the fjord. The twenty-one selected videos document different intertidal landscapes, showing a range of conditions underwater from vital nature to desert land. The sequences in this playlist are made up of videos shot by me and some of the collaborating partners. My underwater videos are shot with a GoPro HERO Session waterproof digital action camera with built in mono microphone. During the explorations, the GoPro was attached to my body. Five videos are from a field survey in a joint project with the Norwegian Institute for Water Research NIVA. In this project we investigated the urban sea areas along the Fjord City with a Blueye underwater drone. In addition, there is one Blueye recording shot by diver Petter F. Schmedling.


The underwater documentation show first tidal expeditions at Sørbystrand Granite geotope by Bunnefjorden during the summer 2018, until the last recordings with NIVA from October 2019. Welcome to 21 different underwater experiences:
