Ocean Observing Prize

Ocean observations underpin our ability to understand the ocean, predict and track potentially destructive tropical storms, monitor fish stocks that communities depend on for sustenance, alert coastal areas of deadly tsunamis, and even monitor for sub-sea activities of foreign powers to protect our uniformed service members.

However, over 80% of the ocean remains unexplored, and without the requisite observations, data, monitoring, and forecasting capabilities, it is difficult for industry to make the strategic siting, development, and management decisions needed to realize the full potential of the blue economy. Given the improvements in computer processing over the last two decades, energy has become the primary constraint on the capabilities of affordable ocean observing platforms such as sensors, autonomous underwater vehicles, buoys, floats, tags, and more.

The Powering the Blue Economy™: Ocean Observing Prize challenges innovators to integrate marine renewable energy with ocean observation platforms, ultimately revolutionizing our capability to collect the data needed to understand, map, and monitor the ocean.

This joint prize between WPTO and NOAA’s Integrated Ocean Observing System (IOOS®) Office seeks to develop new technologies that can help fill the data gaps making it difficult to realize the full potential of the blue economy. Currently in the BUILD Stage, the Ocean Observing Prize includes a series of competitions, with millions of dollars in awards, to encourage rapid innovation in the fields of marine energy and ocean observations.

Past Prizes

Fish Protection Prize

When fish swim into pipes and dam intakes, they become separated from their natural habitat, which impacts native populations, threatens biodiversity, and impedes recovery efforts for threatened and endangered species. WPTO, in collaboration with the U.S. Bureau of Reclamation, launched the Fish Protection Prize, to inspire innovators to compete for $700,000 of combined cash prizes and voucher support to help protect fish from these threats.  In September 2020, three teams were selected as Grand Prize winners, and these teams worked alongside researchers at the Pacific Northwest National Laboratory to advance their solutions.

Competitors proposed solutions for any fish species found in the United States and that could be applied to river and irrigation canal diversions, unscreened diversion pipes for irrigation or municipal water supplies, cooling water intakes of power plants, or dam intakes. New ideas for addressing fish exclusion or improvements to existing technologies were also welcomed.
