“…The term valley is typically used to describe the "path of a channel reach as a straight line between two points" (Flood and Damuth 1987), essentially a construct used to measure aspects of a channel system. Canyon is defined as "long, deep, relatively narrow steep-sided valley confined between lofty and precipitous walls in a plateau or mountainous area, often with a stream at the bottom" (Jackson 1997) and a channel is defined as " an erosional feature "that may be meandering and branching and is part of an integrated transport system (Pettijohn and Potter 1964). Although fluvially generated and deep-water generated morphologic features do share several apparent similarities to deep-water morphologic features (Peakall et al 2000) one must utilize caution in the use of these terms lest one thing the use of the term implies certain processes or deposits in common with similar subaerial deposits.…”

The largest valley formed in five main stages: initiating from narrow channel incision, widening through lateral incision and sidewall slumping, straightening, and finally flooding and infilling. The valley system is ~20,000 feet across and ~ 1,400 feet deep, with what look like well-developed levees ranging from 700 to 1300 feet at their thickest point extending ~19000 feet away from the channel. This system is underlain by a ~700 foot thick mass transport complex and overlain by younger, low sinuosity leveed channel systems. Both of these systems appear to have been sourced by large submarine drainages, originating from a shelf edge sediment source system to feed the rugose slope with deep-water channel pathways uninhibited by salt wall inflation at the time of valley deposition.Major phases of salt thrusting along the southern edge of the Atwater were contemporaneous with the formation of these large, through-going valley system, which appear to be associated with the period of sheet thickening and development of monoclinal basinward dip related to rafted mini-basin docking.Well log signatures show evidence for armored clay drapes along the valley margins as well as a flattening of lateral accretion packages toward the distal end of the system. The flattening of these packages seems to signal proximity to the fan terminus, which would serve as an important indicator of spatial extent of plays in deep-water.vii

“…Rather, runzlemarken appear to represent both ''bedding deformed by penecontemporaneous processes'' (after Pettijohn and Potter 1964) and the former. Therefore, runzlemarken cannot be classified within the framework of Noffke et al's (2001) proposed scheme.…”

“…Terminology of sedimentary structures is generally that of the Pettijohn and Potter (1964) atlas and glossary. The term turbidite is used for graded, partly laminated, sandy beds and laminated silt and clay beds, commonly containing grains of various lithologies (such as foraminifer tests, palagonite grains, large shards, etc.)…”

The DSDP program in the Pacific Ocean for [1973][1974] was based on the plans of the JOIDES Pacific Advisory Panel, within the operational constraints of the DSDP and the long-term objectives of the JOIDES Executive and Planning committees. The Pacific Advisory Panel had assessed a number of first-order scientific problems of broad interest to earth scientists. Topical problems and regional problems were arranged in a matrix so that many sites in the Pacific could be chosen where the highest-priority topical problems could be investigated by drilling where regional information might also be obtained. The major topical problems, not listed in any order of priority, are: (1) composition, structure, and physical properties of oceanic basement; (2) plate genesis and evolution; (3) plate motions; (4) diagenesis and geochemical evolution of sedimentary rocks; (5) structure, history, and origin of various continental margins; (6) biostratigraphy; (7) paleooceanography; and (8) geodynamics and geophysics. PROGRAM AND OBJECTIVES OF LEG 32The northwestern Pacific Ocean is the largest expanse of old oceanic lithosphere, and so the principal theme of Leg 32 set by the Pacific Advisory Panel was the late Mesozoic history of the Pacific Ocean. The main scientific goals originally set for the leg were to: 1) Determine the development of the very deep sea floor of the western Pacific, including the nature of its basement rocks and the age, lithology, and fossil content of the sedimentary rocks overlying acoustic basement. Patterns of linear magnetic anomalies that do not match the sequence of well-dated latest Cretaceous to presentday reversals are present east of Japan, west of the Hawaiian Ridge, near the Phoenix Islands, and bordering the North Atlantic. A principal aim of Leg 32 was to test correlations of these old anomalies by drilling specific sites on the Japanese and Hawaiian sets.2) Establish standard mid-Mesozoic to Recent paleontological-biostratigraphic reference sections for the (present-day) northwest Pacific. Shatsky Rise and Hess Rise are the northern-most of the few broad and irregularly shaped areas of the sea floor that are sufficiently shallow so calcareous fossils are likely to be preserved and yet are isolated from dilution by terrigenous components.3) Determine the paleolatitude for a specific period of volcanicity on Köko Guyot of the Emperor Seamount Chain, which, when compared with the paleolatitude of Midway Islands and the present-day latitude of the active volcanoes on Hawaii, can test a version of the hotspot theory-that a source of magma generation has remained fixed in the earth's mesosphere while the Pacific lithospheric plate has moved across it, with resultant volcanoes forming first the Emperor Seamounts and, after a change in direction of plate motion, the Hawaiian Ridge.Several other geological and operational goals were to include: tracing the paleoequator in the stratigraphic records at the deep-water and rise sites; gathering cores for isotope analysis for paleooceanography studies; det...
