      The speed of growth of nodules is one of the slowest (around centimeter by a few million years). The age of nodules of the central Pacific Ocean is about 2 to 3 million years. II Chemical composition. Chemical analysis showed that nodules consist of various chemical elements, including: manganese (%), iron (%), nickel (% 4. Depth: How deep is the Pacific Ocean?The Pacific is not only the biggest but also the deepest ocean with the deepest trenches. The average depth is about 3, metres/12, Challenger Deep in the Marina Trench, which is located to the West of the Philippines and north of New Guinea, is the deepest point in the Pacific Ocean wm/35,://

      The Antarctic Ice Sheet has greatly affected global climate, sea level, ocean circulation, and southern hemisphere biota during Cenozoic times. Much of our understanding of the evolution of the ice sheet has been inferred from isotopic studies on distant deep-ocean sediments, because few Cenozoic rocks are exposed on the Antarctic ://   The Arabian Sea (AS) is a unique, low-latitude oceanic ecosystem because it is influenced by monsoonal winds that reverse their direction seasonally reversing winds

      To date, the only loggerhead populations for which the migratory routes of their post-hatchlings have been resolved are for rookeries located on the western side of ocean basins, i.e. the northwestern Atlantic Ocean (Mexico, southeastern USA), and the northwestern (Japan) and southwestern Pacific Ocean   The Pacific Decadal Oscillation (PDO) is a long-term fluctuation that occurs in the Pacific Ocean every 20 to 30 years that is characterized by variable sea-surface temperatures in the north-central Pacific and near the Gulf of Alaska. The PDO mainly affects weather patterns in the U.S. Pacific

Twelve genera and 19 species of deep-sea ostracods from the Shatsky Rise, north-western Pacific, were examined and illustrated for taxonomy. Three new species, Cytheropteron nasutum sp.

nov., Poseidonamicus shatskyensis sp. nov. and Legitimocythere stellae sp. nov., are described. Based on these Shatsky Rise ostracods and a comprehensive literature survey of synonyms, we discuss Mesozoic ( Ma) mid-ocean ridge basalt (MORB) recovered from five Deep Sea Drilling Project sites in the central and northwestern Pacific Ocean.

Seawater alteration is responsible for much of the major element variability in these basalts, but magmatic variations are still discernible. Major element modeling of the least altered   Seamounts are important deep ocean entities that serve as reservoirs for varied types of habitats and fauna.

During the Chinese cruises in the northwestern Pacific seamount areas, a new starfish species of order Brisingida, Astrolirus patricki, was found at 1,–2, m depth.

First Online 20 April This chapter describes the measurements of internal tides in the Pacific Ocean together with modeling of the generation and propagation of internal tides in some important regions of the Pacific.

As for corals, the greatest fish biomass and largest fish occur on the uninhabited and protected atolls of the Central and North Central Pacific that may never have been severely degraded (Table 2).

Since the late s, exploration of the deep sea and the sub-seafloor structure has changed our view of the ocean basins dramatically, eventually resulting in the concept of plate tectonics.
