📖 1. Maritime Zones Governance

🔑 Key Concepts & Definitions

Maritime Zone
An area of the sea designated for specific legal and governance purposes, extending from a country's coast to various distances offshore, governed by international law.

Territorial Sea
A maritime zone extending up to 12 nautical miles from a coastal state's baseline, where the state exercises full sovereignty, including control over navigation and resources.

Exclusive Economic Zone (EEZ)
A zone extending up to 200 nautical miles from a country's baseline, where the coastal state has rights to explore, exploit, and manage natural resources, both living and non-living.

High Seas
Areas of the ocean beyond national jurisdiction, considered international waters, governed by international law (UNCLOS), open to all states for navigation, fishing, and resource extraction.

Continental Shelf
The extended landmass of a continent under the sea, beyond the shoreline, where states have rights to seabed resources up to 350 nautical miles from the baseline, subject to international agreements.

Governing Body (UNCLOS & International Law)
Organizations and legal frameworks, such as the United Nations Convention on the Law of the Sea (UNCLOS), that regulate rights, responsibilities, and dispute resolution concerning maritime zones.

📝 Essential Points

• Maritime zones are defined by distance from the coast, with specific rights and restrictions.
• UNCLOS (1982) established legal standards for maritime zones, including sovereignty, resource rights, and navigation freedoms.
• Overlapping EEZs often lead to disputes; boundaries are typically negotiated or determined by median lines.
• The Arctic and South China Sea are hotspots for conflicts over maritime zones due to resource interests and strategic importance.

💡 Key Takeaway

Maritime zones are legal constructs that balance national sovereignty and international rights, but overlapping claims and geopolitical interests often complicate governance and lead to disputes.

📖 2. UNCLOS Framework

🔑 Key Concepts & Definitions

• United Nations Convention on the Law of the Sea (UNCLOS)
  An international treaty (1982) establishing legal frameworks for maritime boundaries, navigation rights, resource rights, and dispute resolution in oceans and seas.

• Maritime Zones
  Legally defined areas of the sea around a coast, including territorial seas, exclusive economic zones (EEZs), and high seas, each with specific rights and regulations.

• Territorial Sea
  The area extending up to 12 nautical miles from a coast, where a state has sovereignty similar to land territory, including control over airspace and seabed.

• Exclusive Economic Zone (EEZ)
  An area extending up to 200 nautical miles from a coast, where the coastal state has exclusive rights to exploit marine resources such as fish, oil, and minerals.

• Continental Shelf Rights
  Rights over the seabed and subsoil extending beyond the territorial sea, up to 350 nautical miles or beyond, for resource extraction like oil and minerals.

• International Seabed Area
  The region beyond national jurisdiction, managed by the International Seabed Authority, designated for peaceful use and resource regulation.

📖 3. EEZ Boundaries

🔑 Key Concepts & Definitions

• Exclusive Economic Zone (EEZ):
  An area extending up to 200 nautical miles from a coastal state's baseline, within which the state has special rights over marine resources such as fishing, mining, and exploration, while sovereignty over the water itself remains limited.

• Baseline:
  The low-water line along the coast from which the breadth of the EEZ is measured; typically the low tide mark on the coast.

• Overlapping EEZs:
  Occur when two or more states' EEZs extend into the same maritime area, often leading to disputes; boundaries are then delineated through negotiations or international agreements.

• Median Line:
  An agreed boundary line equidistant from the nearest points of two states' baselines, used to resolve overlapping EEZ claims when states are less than 400 nautical miles apart.

• Territorial Sea:
  A belt of sea adjacent to a coast, extending up to 12 nautical miles, where the coastal state has sovereignty similar to land territory.

• Continental Shelf:
  The extended perimeter of a continent, which can be claimed for resource rights up to 350 nautical miles from the baseline, subject to international law and geological criteria.

📝 Essential Points

• EEZs grant coastal states exclusive rights to exploit marine resources within 200 nautical miles, but do not grant full sovereignty over the waters themselves.
• When EEZs of neighboring states overlap (less than 400 nautical miles apart), boundaries are typically negotiated or established via median lines.
• Disputes over EEZ boundaries are common, especially in regions with numerous small islands or closely spaced coastlines, such as the South China Sea.
