Uncovering Hidden Activities on the High Seas

Illegal fishing is a major problem that threatens the health of our oceans and undermines the livelihoods of honest fishermen. To combat this issue, Global Fishing Watch is harnessing the power of big data and satellite technology to shed light on suspicious ship activity on the high seas.

Using Satellites to Monitor Suspicious Activity

Global Fishing Watch collects and analyzes billions of satellite signals broadcast by ships. These signals provide valuable information about ship movements, speeds, and locations. By using artificial intelligence and machine learning algorithms, Global Fishing Watch can identify patterns and anomalies that may indicate illegal fishing activities.

Tracking Transshipments: A Major Avenue for Illegal Fish

One of the key targets of Global Fishing Watch’s monitoring efforts is transshipment, the practice of transferring fish from one vessel to another at sea. Transshipment can be used to launder illegally caught fish into the legal supply chain, making it difficult to track and prevent such activities.

Global Fishing Watch’s analysis of satellite data has identified over 90,000 potential transshipment encounters in international waters, far beyond the reach of any single country’s jurisdiction. These encounters involve refrigerated cargo vessels (known as reefers) and fishing vessels operating in close proximity or rendezvousing in suspicious patterns.

Uncovering the Use of “Flags of Convenience”

Another tactic used by illegal fishing operators is the use of “flags of convenience.” These vessels are registered in countries with lax regulations, allowing them to evade stricter controls and accountability measures in their home countries.

Global Fishing Watch’s data reveals that nearly half of the reefers tracked were flying flags of convenience, indicating that the true ownership and origin of these vessels may be obscured. This makes it more challenging to enforce regulations and hold accountable those responsible for illegal fishing.

Empowering Stakeholders to Take Action

Global Fishing Watch’s data is freely available to third parties, including regional fishery management organizations, researchers, and even ordinary citizens. By providing access to this information, Global Fishing Watch empowers others to take action against illegal fishing and improve the transparency and accountability of the seafood supply chain.

Reducing the Sale and Consumption of Illegally Caught Fish

The ultimate goal of Global Fishing Watch’s efforts is to reduce the sale and consumption of illegally caught fish. By shining a light on hidden activities on the high seas, Global Fishing Watch aims to make it more difficult for illegal operators to profit from their activities.

Improving Accountability and Sustainability

Global Fishing Watch’s data is helping to improve accountability in the seafood industry. By tracking transshipments and identifying vessels using flags of convenience, Global Fishing Watch is providing valuable information to regulators and enforcement agencies.

This information can be used to hold accountable those responsible for illegal fishing, deter future offenses, and promote more sustainable fishing practices.

Conclusion:

Global Fishing Watch’s innovative use of big data and satellite technology is transforming the fight against illegal fishing. By providing transparency and accountability to the high seas, Global Fishing Watch is empowering stakeholders to take action and protect the health of our oceans for future generations.

Origins of Humans

Archaeologists have shifted their focus from Europe to Africa to uncover the origins of humans. The discovery of the Taung Child in South Africa in 1924 revolutionized our understanding of human evolution, pushing the focus to Africa’s “Cradles of Humankind.”

Today, there are several fossil candidates for the earliest hominin, dating back 5-7 million years ago. The discovery of “Ardi” in 2009 provided new insights into the evolution of walking in hominins.

Human Evolution

The pace of archaeological discovery is faster than ever before. New research has led to significant revisions of our understanding of human evolution.

In Africa, discoveries of new hominin fossils have expanded our knowledge of our ancestors. Australopithecines like Australopithecus deryiremeda and Australopithecus sediba have reshaped the human family tree.

Perspectives on Homo sapiens have also changed. Fossils from Morocco suggest that our species emerged in Africa around 300,000 years ago, earlier than previously thought. Discoveries from Europe and Asia, including the enigmatic “hobbits” on Flores and the Denisovans in Siberia, indicate that our ancestors may have encountered other hominins as they spread out of Africa.

Ancient DNA

The rise of ancient DNA has revolutionized archaeological research. Since 2010, the sequencing of ancient human genomes has provided new insights into our species’ origins and early history.

Ancient DNA has revealed that modern humans and Neanderthals interbred during the last Ice Age, with many people today possessing some Neanderthal DNA. It has also identified the mysterious Denisovans, who interbred with us and Neanderthals.

Ancient DNA is now being extracted from a variety of sources, including cave dirt and chewing gum, providing new perspectives on individual and family relationships, as well as ancient diets and diseases.

Biomolecules

DNA is not the only molecule revolutionizing the study of the past. Paleoproteomics, the study of ancient proteins, has linked a 9-foot tall, 1,300-pound extinct ape to today’s orangutans.

Dental calculus has revealed information about ancient diets, including the consumption of milk, and has shed light on the human gut microbiome. Lipid residues trapped in pottery have provided insights into the origins of milk consumption and the use of ancient pots as baby bottles.

Big Data

Archaeologists are also using big data to reveal large-scale patterns. Aerial photography and satellite imagery enable researchers to discover new sites and monitor existing ones at risk. Drones provide detailed views of sites, helping to understand their construction and combat looting.

LIDAR technology creates 3D maps of landscapes, revealing ancient cities hidden in dense vegetation. Ground Penetrating Radar detects buried structures without excavation. Teams of archaeologists are combining large datasets to understand human impacts on the planet over thousands of years.

New Connections

Advances in technology are fostering new connections between researchers. Artificial intelligence is being used to identify ancient images in Peru. Crowdsourcing is helping to find new archaeological sites.

Partnerships between archaeologists and scientific specialists are leading to innovative research. The Open Science movement promotes data sharing and accessibility. Public archaeology programs, community digs, and digital museum collections are making archaeology more accessible.

Studying the Past to Change Our Present

Archaeological research provides insights into climate change and how ancient peoples coped with challenging environments. Studies have shown that traditional practices like transhumance can promote biodiversity and healthy landscapes.

Archaeologists are contributing their methods, data, and perspectives to create a vision for a less damaged, more just planet. By studying the past, we can learn from the successes and failures of our ancestors and work towards a better future.
