Monitoring how benthic organisms utilize the sparse food resources available in deep-sea settings
Permanent presence on the seafloor allowing for long-term observation
Thanks to SubC Imaging’s Observatory System, researchers are able to establish large-scale patterns of biodiversity and ecosystem function
Led by Professor Craig Smith (University of Hawaii at Manoa), Professor Lisa Levin (Scripps Institution of Oceanography), and Dr. Fabio De Leo (Ocean Networks Canada), the University of Victoria have been using SubC’s Observatory Solution for their underwater study in Barkley Canyon since 2014.
In May 2014, three humpback whale (Megaptera novaeangliae) rib sections, one 20x20x10 block of Douglas Fir (Pseudotsunga meniziesi), and a ~ 30x30x30 block of authigenic carbonate were placed at a depth of 890m inside the Barkley Canyon -- a site at Ocean Networks Canada NEPTUNE subsea camera observatory. The purpose of this scientific experiment is to monitor the changes triggered by the implantation of various organic and inorganic substrates as well as monitor how benthic organisms utilize the sparse food resources available in deepsea settings.
Full Control of Deep-Sea Observations

每兩個小時,自主的海底攝像機和LED在三個基板上平移,在保持其位置一分鐘時,每個基板拍攝5分鐘的視頻。

Cost Efficient, Long-Term Observation
Setting up a cabled ocean observatory created a permanent presence on the seafloor allowing for long-term observation. This also eliminated the need for costly, more time-consuming monitoring via multiple deployments of ROVs or AUVs in order to gather the data. With the help of the Observatory Solution, the researchers are able to establish large-scale patterns of biodiversity and ecosystem function in areas where there are whale bones.
