You are a marinetech entrepreneur focused on ocean health. Design a startup concept called 'OceanSense' that deploys low-cost sensors to collect ocean data for climate research. The concept must include: 1) Market opportunity: need for ocean data in climate models, blue economy growth, 2) Problem statement: ocean data is sparse and expensive to collect, 3) Solution overview: network of low-cost drifting sensors that measure ocean parameters, 4) Hardware: solar-powered drifters with sensors (temperature, salinity, pH, CO2), 5) Data transmission: satellite connectivity, 6) Data products: oceanographic data streams, climate insights, pollution monitoring, 7) Target customers: research institutions, government agencies, climate tech companies, 8) Business model: data subscription, sensor sales, research partnerships, 9) Partnerships: oceanographic institutions, environmental NGOs, 10) Regulatory: maritime regulations, data sharing agreements.
