A conclusive summary of the original article: A study, pioneering in its approach and scope, has combined AI, GPS data, and satellite imagery to map human industrial activities across the world’s oceans. This research uncovers operations beyond the reach of current monitoring systems, leading to a more accurate depiction of the ocean’s industrial use.
For decades, the vastness of the ocean has kept its use by humanity partially enshrouded in mystery. With economic contributions from marine industries estimated at a hefty $1.5 trillion annually, protecting and managing this marine treasure trove has never been so vital. Yet, the sheer scale of the waters has rendered comprehensive observation impracticable—until now.
A transformative study highlights an unprecedented method of marine observation, unearthing a plethora of activities that were once invisible to the public eye. Researchers at Global Fishing Watch spearheaded a project using a trove—a staggering 2 million gigabytes—of satellite imagery and artificial intelligence to decipher the complex dance of the world’s fishing vessels, shipping traffic, and oceanic structures accumulated over five years.
The findings were captivating: around 75% of fishing activity was occurring outside the realm of public AIS monitoring systems, especially near Africa and South Asia. This elucidation dramatically altered the perceived geography of global fishing, with Asia unexpectedly dominating the seas. For non-fishing vessels, roughly a quarter were undetected by the usual tracking systems, and at least 28,000 sea-based structures, mainly pertaining to energy production, were delineated. Notably, the rise of wind turbines appeared to eclipse oil platforms, emphasizing a global shift toward renewable energy.
The consequences of this research are monumental, potentially elevating the management and conservation of marine resources on various fronts—from cracking down on illegal fishing to bolstering climate change strategies. The expansive dataset is now accessible via the Global Fishing Watch data portal, promising ongoing updates and extensions to further fortify ocean governance.
What is the significance of the new study on ocean use?
The study is pioneering in that it uses AI, GPS data, and satellite imagery to create a comprehensive map of human industrial activities in the world’s oceans. The significance lies in its ability to reveal operations that were previously beyond the reach of existing monitoring systems.
Why is the ocean’s industrial use important to monitor?
Marine industries contribute around $1.5 trillion annually to the economy. Monitoring these activities ensures effective protection and management of these valuable resources.
What methods were used in the study?
Researchers utilized a combination of artificial intelligence, satellite imagery, and GPS data to analyze the industrial use of oceans. They gathered this information from a huge volume of data—2 million gigabytes of satellite imagery—over five years.
What were the key findings of the study?
Around 75% of fishing activity was discovered to take place outside the coverage of public AIS monitoring systems, especially near Africa and South Asia. Furthermore, the study revealed that Asia is a dominant force in maritime fishing. For non-fishing vessels, about a quarter went undetected by common tracking systems, and at least 28,000 sea-based structures, mainly energy-related, were identified with a notable rise in wind turbines compared to oil platforms.
What is AIS?
AIS stands for Automatic Identification System, which is a tracking system used for identifying and locating vessels by electronically exchanging data with other nearby ships and AIS base stations.
How can the data from this study be accessed?
The dataset from the study is available through the Global Fishing Watch data portal, which promises ongoing updates to enhance marine resource management.
How might this research impact ocean governance?
The detailed mapping of ocean use has the potential to improve various aspects of ocean governance. This includes combating illegal fishing, enhancing conservation efforts, and supporting climate change mitigation strategies.
