Pulse is built for aquaculture farmers. It provides difficult to find water quality data such as temperature, salinity, dissolved oxygen, chlorophyll, and wave height, ocean current, and wind. Pulse relies on remote sensing data from dozens of satellites to provide worldwide coverage. The application takes all of this data and displays it in an easy to view format. Farmers need to be able to see below the surface and understand what is happening in the water where their fish, shellfish, or seaweed lives. Pulse provides this data so farmers can make informed decisions and understand risks before they happen. You can check Pulse the same way you check the weather everyday. Unlike water quality sensors Pulse is reliable and accessible from any location. It is easy to see a large area or many different locations. Zoom in to see local data near your farm and zoom out to see large-scale trends. Fast loadingThis unique service was developed by Umitron for farmers. At Umitron we believe aquaculture is the future of sustainable and healthy protein production. Our goal is to provide world leading technology to farmers so they can grow happy and healthy fish, shellfish and seaweed.
