FURUNO's Blue Carbon Initiative

Blue Carbon ecosystems (seaweed beds, seagrass, mangroves) absorb atmospheric CO₂ and sequester carbon in oceans, playing a crucial role in climate change mitigation. FURUNO is pioneering comprehensive ocean health monitoring by leveraging its advanced acoustic survey technologies, including fish finders and sonar systems, to map Blue Carbon ecosystems across vast marine areas.

Through systematic mapping and monitoring of these critical ecosystems, FURUNO enables scientists, governments, and conservation organizations to assess ocean health in real-time, identify areas requiring protection, and implement targeted conservation strategies. This data-driven approach allows for proactive measures to preserve marine biodiversity and maintain the ocean's natural carbon sequestration capabilities.

FURUNO's "Ocean 5.0" vision for 2050 envisions "a future where all living beings receive ocean benefits and give back to the sea" - achieved through continuous monitoring, scientific understanding, and appropriate conservation actions based on comprehensive Blue Carbon mapping.

Advanced Acoustic Survey Technology

FURUNO's innovative approach utilizes 200kHz acoustic signals from fish finders to detect and map seaweed and seagrass ecosystems on the seafloor. This cost-effective, scalable method enables comprehensive surveys of wakame, sargassum, kelp, and eelgrass - critical Blue Carbon species along Japan's coastlines and beyond.

The technology creates detailed distribution maps by combining acoustic data with GPS positioning, calculating precise seaweed bed areas and volumes through advanced linear interpolation. This systematic mapping capability allows FURUNO to monitor ecosystem changes over time, detect environmental threats early, and provide essential data for marine conservation planning and climate action initiatives.
