anic and earthquake activity
sometimes referred to as the "Pacific Ring of Fire"; subject to
tropical cyclones (typhoons) in southeast and east Asia from May to
December (most frequent from July to October); tropical cyclones
(hurricanes) may form south of Mexico and strike Central America and
Mexico from June to October (most common in August and September);
cyclical El Nino/La Nina phenomenon occurs in the equatorial
Pacific, influencing weather in the Western Hemisphere and the
western Pacific; ships subject to superstructure icing in extreme
north from October to May; persistent fog in the northern Pacific
can be a maritime hazard from June to December

Environment - current issues:
endangered marine species include the dugong, sea lion, sea otter,
seals, turtles, and whales; oil pollution in Philippine Sea and
South China Sea

Geography - note:
the major chokepoints are the Bering Strait, Panama Canal, Luzon
Strait, and the Singapore Strait; the Equator divides the Pacific
Ocean into the North Pacific Ocean and the South Pacific Ocean;
dotted with low coral islands and rugged volcanic islands in the
southwestern Pacific Ocean

Economy Pacific Ocean

Economy - overview:
The Pacific Ocean is a major contributor to the world economy and
particularly to those nations its waters directly touch. It provides
low-cost sea transportation between East and West, extensive fishing
grounds, offshore oil and gas fields, minerals, and sand and gravel
for the construction industry. In 1996, over 60% of the world's fish
catch came from the Pacific Ocean. Exploitation of offshore oil and
gas reserves is playing an ever-increasing role in the energy
supplies of the US, Australia, NZ, China, and Peru. The high cost of
recovering offshore oil and gas, combined with the wide swings in
world prices for oil since 1985, has led to fluctuations in new
drillings.
