Tidal is combining machine learning with new types of underwater perception hardware to gain unprecedented visibility into aquatic relationships and ecosystems. Tidal, a project inside Alphabet's Moonshot Factory, is developing a new platform to advance our understanding of ocean health and climate change. "Through our collaboration with Cognizant, we hope to build on our initial success in the Norwegian aquaculture industry, and eventually expand to other sectors of the Blue Economy to make a meaningful impact in ocean health and global decarbonization." "To preserve ocean health, we need to take an innovation-driven and collaborative approach with aquaculture companies and other businesses that make their living on and in the ocean," said Tidal Founder and CEO, Neil Davé. In shipping, sea transport companies can use machine learning models to analyze micro-weather systems, current speeds and port data traffic to optimize shipping route and port arrival times for lower fuel usage. For example, in aquaculture fish farmers can use machine perception tools and AI to automate feeding time in accordance with the hunger levels of the fish to reduce wasted feed, a significant carbon emissions source while improving growth metrics. Ocean based-companies can drive better business outcomes and contribute to decarbonization through lowering the carbon footprint of their operations. "We welcome this important collaboration with Tidal to work together with clients to support their holistic, systems-level change." "With digital technology ocean industries can not only become more resilient and future-proof in the face of a more unpredictable and rapidly changing environment, but they can help make oceans healthier and address humanity's biggest problems – from food production to renewable energy to climate change," said Stig Martin Fiskå, Global Head of Cognizant® Ocean. Through its longstanding relationships with global enterprises that make up the Blue Economy, Cognizant will be able to help companies integrate Tidal's technology into their enterprise systems, linking data from across their business to gather insights and make decisions that improve efficiency throughout the entire value chain. The current platform has been built and validated using Tidal's AI, which has been trained on 8 billion underwater observations of fish behavior across 900 terabytes of operational video. Cognizant will collaborate with Tidal to make these technologies more widely available to the aquaculture industry to help them make more intelligent decisions, build more resiliency into their operations, and run more efficiently in a strict regulatory environment.įor the past five years, Tidal has worked with aquaculture industry leaders to develop its solution, which includes a system of underwater cameras, sensors, machine perception tools and software designed to interpret complex ocean environments. Tidal has developed a digital technology solution that utilizes innovations in underwater perception, machine learning, AI, and automation to gather and analyze data. Together with aquaculture, part of blue food, these sectors of the blue economy represent a significant opportunity to decarbonize large ocean-based industries. White dwarf is crystallized.Longer term, Cognizant and Tidal will explore additional ways to apply the platform to make an impact on industries that depend on ocean insights, including blue transportation blue energy, and blue carbon. Depending on the stellar mass andĬomposition, however, these relations can be affected by a few percent when the Show that there exist approximate equation-of-state insensitive relationsĬonnecting the mass, moment of inertia, tidal deformability, and f-modeįrequency for pure fluid white dwarfs. The tidal deformability can change by aįew to about 10 percent when a white dwarf becomes fully crystallized.
