The first mission was to monitor the algal bloom in Frohavet earlier this year. In addition, HYPSO-1 has taken more than hundred&nbsp; hyperspectral images from all parts of the world since January.<\/p>\n\n\n\n<p>The May mission was to scan Kongsfjorden outside Ny-\u00c5lesund in Svalbard, to observe the possible algal blooms and identify which types of blooms could be found. The satellite was used together with other platforms: subsea drones, unmanned surface vehicles, aerial drones, and water samples collected from boats.<\/p>\n\n\n\n<p>The goal with this research was to test the so-called \u00abobservational pyramid\u00bb. All these platforms were used simultaneously to map a certain area in Kongsfjorden.<\/p>\n\n\n\n<p>\u201cWe have demonstrated that a small satellite has a place in the observational pyramid,\u201d says Eirik Sivertsen, project manager for the research infrastructure for small satellites at NTNU.<\/p>\n\n\n\n<p>Sivertsen was in Ny-\u00c5lesund to see how the observational pyramid worked.<\/p>\n\n\n\n<p>\u201cThere are aspects that must be improved but sharing information between different observational platforms that work together can have huge benefits for researchers,\u201d Sivertsen says.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Taking the pulse of the ocean<\/h2>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"956\" height=\"228\" src=\"https:\/\/nyheter.ntnu.no\/wp-content\/uploads\/2023\/03\/3.png\" alt=\"\" class=\"wp-image-983\" srcset=\"https:\/\/nyheter.ntnu.no\/wp-content\/uploads\/2023\/03\/3.png 956w, https:\/\/nyheter.ntnu.no\/wp-content\/uploads\/2023\/03\/3-300x72.png 300w, https:\/\/nyheter.ntnu.no\/wp-content\/uploads\/2023\/03\/3-768x183.png 768w\" sizes=\"auto, (max-width: 956px) 100vw, 956px\" \/><figcaption class=\"wp-element-caption\">A RGB-representation of a hyperspectral image from Forlandet in Svalbard May 29 2022.

The University of Troms\u00f8 brought an unmanned surface vehicle with acoustic sensors and CTD-sensors.<\/p>\n\n\n\n<p>The Department of Marine Technology tested autonomous underwater vehicles with different sensors and a small, unmanned Otter with a subsea hyperspectral imager from Ecotone. The Department of Biology and UNIS took water samples before, during and after the experiment to measure the physiology of algal cells to see the different species, the biomass, the photosynthesis, and the health condition \u2013 important information in addition to the measurement of algal bloom in bigger areas.<\/p>\n\n\n\n<p>\u201cBy using all these platforms in the same area, sharing information and collaborating, we can collect data more effectively, and we also get more data than we do by collecting data from the ocean in traditional ways,\u201d says Geir Johnsen, Professor in marine biology at NTNU AMOS.<\/p>\n\n\n\n<p>To this day the biologists use very time-consuming methods to map life in the ocean \u2013 and they are measurements that can be used for calibrating the remote measurements done in bigger areas.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Can be used for a lot of different purposes<\/strong><\/h2>\n\n\n\n<p>\u201cWe think the observational pyramid can be developed. We have worked closely with biologists to see what they need, but we see a lot of other potential aereas of use,\u201d says Tor Arne Johansen.<\/p>\n\n\n\n<p>He mentions that the aquaculture industry can have hugely benefits from more effective and automated systems to map and monitor conditions that may impact fish welfare and the environment around the fish farms. The technology can be used to strengthen the knowledge of our freshwater systems. And in the future \u2013 could a more automated, underwater coast guard be possible?<\/p>\n\n\n\n<p>\u201cThis can be a foundation for a brand-new industry, with value creation and workplaces for Norway in the future,\u201d Johansen says.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Contact persons<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Eirik Sivertsen, Project Manager NTNU<br>E-mail: Eirik.S.Sivertsen@ntnu.no.
