Abstract The evolution and resulting morphology of a contourite drift system in the SE Pacific oceanic basin is investigated in detail using seismic imaging and an age-calibrated borehole section. The Nazca Drift System covers an area of 204 500 km2 and stands above the abyssal basins of Peru and Chile. The drift is spread along the Nazca Ridge in water depths between 2090 and 5330 m. The Nazca Drift System was drilled at Ocean Drilling Program Site 1237. This deep-water drift overlies faulted oceanic crust and onlaps associated volcanic highs. Its thickness ranges from 104 to 375 m. The seismic sheet facies observed are associated with bottom current processes. The main lithologies are pelagic carbonates reflecting the distal position relative to South America and water depth above the carbonate compensation depth during Oligocene time. The Nazca Drift System developed under the influence of bottom currents sourced from the Circumpolar Deep Water and Pacific Central Water, and is the largest yet identified abyssal drift system of the Pacific Ocean, ranking third in all abyssal contourite drift systems globally. Subduction since late Miocene time and the excess of sediments and water associated with the Nazca Drift System may have contributed to the Andean orogeny and associated metallogenesis. The Nazca Drift System records the evolution in interactions between deep-sea currents and the eastward motion of the Nazca Plate through erosive surfaces and sediment remobilization.

A new genus and species of marine crayfish, Palibythus magnificus, is described from deep water off Western Samoa. Palibythus is placed in the Palinuridae, among the 'Stridentes' group of genera, because of the well-developed stridulatory organ. It differs from all other known genera, except Palinurellus, by the flat triangular rostrum and the narrow thoracic sternum; Palinurellus, however, lacks a stridulatory organ. The relationships of Palinurellus are discussed and the Synaxidae is replaced in synonymy with the Palinuridae. Palinurellus wieneckii is recorded from New Guinea and Solomon Islands waters for the first time.

This research applies a literary anthropology approach that focuses the study on the uniqueness of Queqeeq character represented in Moby Dick (Mellvill, 1962). That uniqueness contains physical characteristics as a Polynesian, cultural behavior, belief, and dialect. Queqeeq character is described as a very sober man, consistent in his words and manners, and referring to Polynesid race, with large black eyes, natural dark skin, and unworldly tattoos. Quegeeq is represented as a character of a hard worker, agile, and tough as a seaman in the Pacific ocean. In religion, Queqeeq is described as a primitive ritual-religion person, who is serious in fasting; not to eat and talk in the Ramadan time, prays ritually through a wooden idol, following the ritual-religion custom of Polynesian. Generally, it can be concluded that Melville in Moby Dick (1962) succeeds in representing the specific characteristics of Polynesian culture through character and characterization of Queqeeq
