Bedrock Ocean, a California-based ocean exploration company, has raised $25 million in a Series A-2 round led by Primary and Northzone, according to reporting by TechCrunch.

Using its proprietary mission software and autonomous underwater vehicles, or AUVs, Bedrock conducts nearshore geophysical surveys and provides its customers with high-resolution seafloor data. Its services support offshore wind, oil and gas projects as well as maritime research and security.

Brandon Mah, Bedrock’s COO, told TechCrunch that two of the company’s AUVs can cover the same area as one of the large ships traditionally used for mapping the ocean floor. The machines are powered by lithium-ion batteries and can run for 10 to 12 hours as they use sonar and magnetic sensors for surveying.

The company’s new capital will help to advance its mission of making ocean mapping efficient, affordable, safe and more accessible.
