Multispecies Neighbourhoods in Urban Sea Areas by Elin Tanding Sørensen

“Multispecies Neighborhoods in Urban Sea Areas,” concerns the interface between art, marine ecology, landscape architecture, and urban development. The explorative action research is motivated from a need to act, and to help people discover a hitherto invisible landscape: creating awareness of its spatial qualities, colours, the smell of low tide and the myriad of lifeforms within this symbiosis of sea and shore. The aim is to expand the horizon of those building into this watery world. With a desire to co-create diverse and liveable urban bluescapes, the work has emerged in- and through a state of wonder.

Undersea Fieldwork

From the multisensory fieldwork 2017-2020, with expeditions along the inner Oslofjord's shorelines, urban sea areas and the islands of the fjord. The twenty-one selected videos show different intertidal landscapes and a range of conditions undersea — from vital marine nature to desert land. The sequences in this playlist are made up of videos shot by me and some of the collaborating partners. Mine 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 fieldwork starts with the first tidal expeditions at Sørbystrand by Bunnefjorden during the summer 2018,
until ‎the last recordings with NIVA from October ‎2019. Welcome to 21 different underwater experiences:
