Maritime Zones Explained: The Boundaries of Our Seas

The concept of maritime zones is a cornerstone of international maritime law, defined primarily by the United Nations Convention on the Law of the Sea (UNCLOS). These zones determine the extent of a coastal state’s rights, responsibilities, and jurisdiction over the waters and resources adjacent to its shores. Background • Maritime zones were established to resolve disputes over navigation, resource ownership, and national security. • Boundaries are measured from a country’s baseline (usually the low-water mark along the coast). • The key zones include: • Internal Waters – full sovereignty like land territory. • Territorial Sea – up to 12 nautical miles. • Contiguous Zone – up to 24 nautical miles. • Exclusive Economic Zone (EEZ) – up to 200 nautical miles. • Continental Shelf – may extend beyond 200 nautical miles depending on natural features. Purpose • Internal Waters – treated like land territory, full state control. • Territorial Sea (12 nm) – authority over navigation, resources, and law enforcement. • Contiguous Zone (24 nm) – enforcement against smuggling, illegal entry, and security threats. • Exclusive Economic Zone (200 nm) – exclusive rights to explore and exploit resources (fish, oil, gas). • Continental Shelf – rights over seabed resources even beyond EEZ. Importance • Safeguards national security and territorial sovereignty. • Ensures sustainable use of marine resources (fisheries, oil, gas). • Provides control over shipping routes and trade lifelines. • Strengthens sovereignty in disputed waters (vital for nations like the Philippines). • Globally, reduces conflict, promotes order and cooperation, and protects the marine environment.

Anti-Exposure Suit

An anti-exposure suit is a specialized protective garment used in the maritime environment to safeguard individuals from the dangers of cold water, extreme weather, and emergency situations at sea. It is typically bright orange for high visibility and made from waterproof, fire-resistant materials that help reduce heat loss and protect the wearer from harsh conditions while performing rescue or evacuation duties. Designed to cover almost the entire body except the head and hands, these suits often include gloves and a hood, and they must be capable of being put on quickly usually within 2 minutes without assistance. They provide inherent buoyancy and thermal protection so that if someone enters cold water, their body temperature drops slowly, helping prevent hypothermia. Anti-exposure suits are also built to allow the wearer to climb ladders, jump into water, swim short distances, don a lifejacket, and carry out evacuation or rescue duties effectively even under stress.

UNDERSTANDING ABOUT ISPS CODE

Introduction The International Ship and Port Facility Security (ISPS) Code is a comprehensive set of measures designed to enhance the security of ships and port facilities. It was adopted by the International Maritime Organization (IMO) under the framework of the International Convention for the Safety of Life at Sea (SOLAS), specifically through an amendment introduced in December 2002. The ISPS Code officially came into force on 1 July 2004, marking a turning point in maritime safety and global security.
