The Dartmouth-based Centre for Ocean Ventures and Entrepreneurship, or COVE, will host its annual Demo Day on Wednesday, with bluetech companies demonstrating their innovations off the facility’s dock.

The event will include 17 exhibiting companies from as far away as British Columbia and Denmark, and COVE said in a statement it expects about 400 private sector and government decision-makers from the international oceans community to attend. The Demo Day is the closing event of the Ocean Technology Council of Nova Scotia’s H2O Conference.

In addition to the main demo day stages, other COVE startups will also be showing off their technology from their manufacturing and incubator spaces in the converted Coast Guard base.

And concurrently with the Demo Day, COVE will host Pitch + Roll — an invitation-only event that will give 10 pre-selected companies the chance to pitch an audience of international bluetech investors.

Also launching as part of the festivities is a new mural at COVE by Mi’kmaq artist Lorne Julien. It is located in one of COVE's stairwells and depicts an eagle with its wings wrapped around a leatherback turtle and her hatchlings.

“When I painted the turtles I was thinking about how these amazing animals travel between the Caribbean and Nova Scotia and how turtles move between land and the ocean,” wrote Julien on his website. “This painting reminds us about connections, in the world, between the elements and how whatever we do as humans has implications on all other creatures in the world.”

The Demo Day will run from 10 a.m. to 5 p.m, with companies divided between three stages. More information can be found here.
