The ocean economy refers to the broad range of economic activities that take place in the ocean, seas, and coastal areas. It includes both established sectors such as marine transport and shipping, fisheries and aquaculture, offshore oil and gas, shipbuilding, and tourism, as well as emerging sectors such as offshore renewable energy, marine biotechnology, and deep-sea mining. These industries contribute significantly to global GDP, employment, food security, trade, and energy supply. The ocean economy also supports ecosystem services such as carbon sequestration, biodiversity, and coastal protection.
The U.S. encompasses a wide array of industries that operate in or depend on the ocean and Great Lakes. It includes sectors such as marine transportation and shipping, offshore oil and gas, living marine resources, shipbuilding, tourism and recreation, and emerging areas, including marine renewable energy. According to the National Oceanic and Atmospheric Administration (NOAA), the U.S. ocean or marine economy contributed $476 billion to the national GDP and supported around 2.4 million jobs in 2022. Additionally, advancements in offshore wind energy and maritime logistics would create new economic opportunities during the forecast period. The U.S. government is increasingly investing in sustainable ocean economy initiatives, research, and coastal resilience strategies to support long-term growth.
The U.S. ocean economy market demand is driven by the growing production of oil and gas. According to the International Energy Statistics published in March 2024, the U.S. has produced more crude oil than any nation for the past six years in a row, which directly expanded the ocean economy as energy companies required more support services, such as underwater robotics, marine construction, and supply vessels, boosting demand for specialized maritime businesses. Rising production also increased the demand for oil tankers and LNG carriers, thereby strengthening the shipping and logistics sectors. Therefore, the surge in energy production created jobs, accelerated technological advancements in offshore engineering, and reinforced the ocean economy’s role in global energy supply chains.
Expanding Coastal Infrastructure: The expansion of coastal infrastructure, including ports, harbors, and offshore terminals, is fueling the ocean economy by increasing shipping volumes and boosting demand for logistics and freight services. Enhanced coastal infrastructure is also supporting offshore wind farms and oil rigs, driving growth in the marine construction and maintenance industries. Better transportation links are further attracting fisheries, aquaculture, and tourism businesses, creating jobs and stimulating local economies. Additionally, modernized infrastructure is encouraging investments in shipbuilding, marine technology, and coastal real estate, thereby further strengthening the expansion of the ocean economy.
Increasing Seafood Demand: The rising demand for seafood in the U.S. is fueling fishing activities, prompting the aquaculture industries to expand their operations and invest in more advanced vessels and equipment. This growth is propelling the need for processing plants, cold storage facilities, and efficient supply chains, strengthening marine logistics and port services. According to the U.S. Department of Agriculture, the value of U.S. seafood imports expanded by 133% from 1995 to 2021. Higher seafood consumption is also driving innovation in sustainable fishing techniques and offshore aquaculture farms, boosting demand for marine biotechnology and environmental monitoring services. Therefore, the growing demand for seafood is fueling the ocean economy market growth in the U.S.
Based on industry type, the segmentation includes marine transport and shipping, marine tourism and recreation, fisheries and aquaculture, offshore oil and gas, government, and others. The marine tourism and recreation segment held 34.20% of the U.S. ocean economy market share in 2024 due to strong demand for coastal vacations, recreational boating, and marine wildlife experiences. The post-pandemic surge in travel, coupled with increasing disposable incomes and a growing preference for outdoor activities, fueled the dominance of the segment. Coastal states such as Florida, California, and Hawaii saw record numbers of visitors, boosting revenues from cruise lines, waterfront resorts, and recreational fishing charters. Additionally, technological advancements, such as online booking platforms and eco-tourism initiatives, made marine experiences more accessible and appealing to a broader audience, contributing to the segment’s dominance.
The fisheries and aquaculture segment is projected to register a CAGR of 4.1 from 2025 to 2034, owing to the rising demand for sustainable and locally sourced seafood and increasing investments in aquaculture facilities, especially in coastal and Great Lakes states. Federal programs, such as the National Aquaculture Plan and NOAA’s support for marine resource management, have encouraged innovation and scalability in fish farming operations. Additionally, concerns about climate change and overfishing are shifting policy and market focus toward sustainable aquaculture, thereby strengthening its future market position.
The U.S. ocean economy is a dynamic and highly competitive market, driven by industries such as offshore energy, maritime shipping, marine technology, and environmental sustainability.
