CRIMAC will improve and automate the interpretation of data and images from modern broadband acoustics on research vessels and fishing boats by using cruises and experimental field research, artificial intelligence, drones and inspection technology.
Direct measurement of fish size is useful in fish farming, fisheries and marine research, and we have tested how broadband echosounders can be used for this purpose.
Early Career Scientist Conference in Canada and a tour of the Fisheries and Marine Institute of Memorial University
PhD student Taraneh Westergerling reports from her presentation at the the ICES/PICES early career scientist conference.
2021 was the first full year for SFI CRIMAC. Despite the pandemic, the center has been able to progress well. The annual report for 2021 is now published and can be accessed here (pdf).
Different data-preparation strategies suitable for acoustic target classification using a deep learning is tested. You will find more information here:
CRIMAC had five contributions to the ICES Working Group on Fisheries Acoustics Science and Technology (WGFAST)
The cruise report from the joint survey for CRIMAC and the IMR sampling gear project on G.O. Sars November 2021 is now published.
Marine researcher Nils Olav Handegard takes the helm after Egil Ona.
CRIMAC had three contribtions for “The 45th Scandinavian Symposium on Physical Acoustics.”
This essay outlines how we use machine learning in marine science in Norway. CRIMAC is collaborating with Visual Intelligence SFI where the Norwegian Computing centre and the University of Tromsø are partners on using machine learning on the vast amounts of data from modern echo sounders.
In this newsletter, project manager Nils Olav Handegard gives an overview of recent CRIMAC activities.
Deep neural networks require a substantial amount of data for training. We have developed a new method for training deep networks for acoustic target classification with only 10 % of the training data compared to traditional methods. The work is a collaboration between the COGMAR project and the Visual Intelligence SFI.
Norway has a long-standing collaboration between science, technology and fishing industry within “smart fisheries”. CRIMAC builds on this collaboration. Click to read our contribution in this special issue of Journal of Technology.
Norway's Institute of Marine Research to use robot platforms and enhanced digital infrastructure to harvest data from the seas.
This is good news for both fishers and fish stocks.
The CRIMAC centre wants the echo sounder itself to be able to distinguish between herring, mackerel, shrimps and gas emissions. Now scientists have completed their first expedition to learn the “dialect” of herring.
