Study Notes

Pacific Background

Pacific Ocean is the largest geographical feature on Earth, encompassing nearly one-third of the planet's surface.
It holds nearly half of the Earth's seawater (46%).
The Pacific is wider than both the Moon and Mars.
The top 5cm of the Pacific Ocean holds more water than the Earth's atmosphere.
The Pacific has a greater concentration of living creatures than anywhere else on Earth.
The Pacific is 252 times larger than France (approximately 544,000 km²).
The Pacific Ocean's maximum depth is 15,000km.
Its width is 19,000km (Paris to New York is roughly 18,500 km).
The Pacific Ocean's total area is 165.2 million km².

Pacific Islands

Easter Island, while in the Pacific Ocean, is considered part of Chile, not a Pacific island nation.
The Mariana Trench is the deepest location on Earth, reaching 11km below sea level.
It is also one of the most volcanically active regions of the Earth.
The Pacific "Ring of Fire" encompasses 75% of the world's active volcanoes and over 90% of the Earth's earthquakes.
Tambora Eruption (1815) resulted in the deaths of over 10,000 directly, and an estimated 80,000 indirectly from crop failure/famine.
Atolls are ring-shaped coral reefs surrounding lagoons, with over 440 observed in the Pacific.
Coral reefs flourish in clear, shallow waters (21-29°C) with ample sunlight.
25,000 islands exist in the Pacific Ocean.
Over 1,000 islands are found in each Pacific country.
Many Pacific Islands were grouped into countries by European and U.S. colonisers in the 19th and 20th centuries.

Pacific Demography

The Pacific population is approximately 18 million (2022).
Papua New Guinea (PNG) has an estimated 9 million people.
New Zealand's population is around 5 million.

Austronesians later settled Polynesia (approximately 1,000 years ago.)
European explorers ventured into the Pacific from 1521 onwards.
Austronesian migrations across the Pacific were contemporaneous with Viking voyages across the Atlantic.
