title: Processed multichannel seismic data in the Venezuelan Basin and over the Beata Ridge, acquired during the R/V Maurice Ewing survey EW9501 (1995)

description: This cruise collected data in the Venezuelan Basin and over the Beata Ridge. The cruise had multiple purposes. Venezuela Basin: 1) Define the rough/smooth basement boundary better and examine the spatial and temporal relationship between the different crustal types. 2) Ascertain the crustal velocity structure. 3) Determine crustal thickness variations acrooss the rough/smooth boundary. 4) Image Moho, sub B, and Cretaceous to early Tertiary sediment reflectors. 5) Examine the link between the observed magnetic lineations and structural lineations. Beata Ridge: 1) Determine if crustal thickness variations can explain the differential topography between Beata Ridge and the Venezuelan and Columbian Basins. 2) Determine if additional deformation affected the region due to differential plate motion. 3) Ascertain whether the additional deformation and the resulting topography was due to tensional or compressional forces. 4) Address the history of the relative motion of the Caribbean plate and discern whether the azimuthal and deformation data can be better explained by one or two plates for the Caribbean region by determining the deformational history of the Beata Ridge. Funded by NSF grant OCE93-02578.

title: Processed multichannel seismic data, including SCREECH Transact 1, crossing the Newfoundland margin, acquired during the R/V Maurice Ewing survey EW0007 2000)

description: This data set consists of SCREECH Transect 1 (1MCS) and lines 101, 102, and 103. This ODP site survey on the Newfoundland margin was a joint project, SCREECH (Studies of Continental Rifting and Extension on the Eastern Canadian SHelf), between the University of Wyoming, WHOI, Dalhousie University, and Danish Lithosphere Centre scientists. The Ewing acquired MCS, magnetic, gravity, and multibeam bathymetric data while the Oceanus acquired wide-angle reflection/refraction data via ocean-bottom seismometers/hydrophones (OBS/Hs). This cruise was to provide a critical dataset for testing models of continental rifting, breakup, and initiation of seafloor spreading in a non-volcanic rifted environment. Its objectives were to: 1) characterize the nature of the crust transitional between oceanic and continental crust in the region; 2) provide a comparison with the Iberian margin, thereby allowing testing of models of pure-shear vs. simple-shear during rifting; and 3) determine the amount of igneous material intruded and extruded during rifting, providing comparative data with other volcanic rifted margins, such as the East Greenland margin. Funding was provided by NSF (grants OCE98-19599 and OCE98-19053), Dalhousie University, Geological Survey of Denmark and Greenland, Danish National Research Foundation (Danmarks Grundforskningsfond), and the Natural Sciences and Engineering Council of Canada.

title: Ocean bottom seismometer (OBS) data on the Mid-Atlantic Ridge, acquired during the R/V Maurice Ewing survey EW9704 (1997)

description: This 1997 Ewing expedition to the Mid-Atlantic Ridge, part of the Nobel at the Mid-Atlantic Ridge Seismic Experiment, collected ocean bottom seismic refraction and single-channel seismic data. The purpose was to measure the reflected and refracted arrivals of seismic energy from sections of the mid-ocean ridge spreading center which have known, previously sampled, rock compositions. These data could then be used to identify and map rock types and test existing models for subsurface ridge structure, possibly providing a 3-dimensional map of the structure of a slow-spreading mid-ocean ridge.

description: This data set was acquired with the LDEO Portable HiRes Multi-Channel Seismic during R/V Cape Hatteras expedition CH0698 conducted in 1998 (Chief Scientist: Dr. Gregory Mountain). A joint project between LDEO and Rutgers University, this project was a detailed, high resolution seismic study of the New Jersey margin. The cruise served as a site survey for IODP Expedition 313. The project had a series of objectives, including seismically tying land drilling to offshore work; mapping spatial variability in imaged Tertiary sediments; examining sea-level fluctuation in seismic data; and surveying shallow water sites for potential future drilling. Data were acquired as part of the project: High-Resolution Nested Imaging of Nearshore Sequences, New Jersey Inner Continental Shelf: Linking Onshore and Offshore Sea-Level Studies, and funding was provided by NSF grant: OCE97-12191.

title: Processed multichannel seismic data in the Woodlark Basin, acquired during the R/V Maurice Ewing survey EW9510 (1995)

description: This was an ODP site survey (prior to leg 180) to characterize the rift-to-spreading transition in the Woodlark Basin. The purpose was to study the structural and volcanic processes and the dynamics of the upper mantle that are associated with the splitting of continents. The lateral variation from continental rifting to seafloor spreading within the Woodlark Basin makes it an ideal area to investigate the active process of rifting and spreading center propagation into a continent. The results of this study will provide necessary site survey data with which to plan drilling in the Woodlark Basin. Funded by NSF grant OCE92-01691.

title: Processed multichannel seismic data in the Solomon Islands convergent zone, Southwest Pacific Ocean, acquired during the R/V Maurice Ewing survey EW9511 (1995)

description: A U.S.-Japan cooperative program to map crustal and perhaps upper mantle structures in the Solomon Islands convergent zone. Due to a major cable loss on the previous cruise the cable configuration varied between 112 and 128 channels as new sections were repaired or on-loaded (see cruise report). Japanese OBS's were used in this experiment along line SI-1. The primary objective of the MCS study and an independently proposed OBS study by Drs. K. Suyehiro and colleagues at the Ocean Research Institute in Tokyo, Japan, is to test two models for the formation of the Malaita anticlinorium - the deformed wedge of Cretaceous-Cenozoic pelagic limestone, basalt, and clastic rocks that most previous workers agree to be an emergent part of the Ontong Java Plateau. One model predicts tectonic wedging of the Solomon island arc beneath the Ontong Java plateau. A second, alternative model predicts a more familiar oceanic accretionary wedge geometry with northeastward (plateauward) offscraping and thrust imbrication of plateau rocks. Our proposed MCS-OBS study focusing on the Malaita anticlinorium and North Solomon trench will use state-of-the-art data acquisition and processing techniques to address fundamental questions concerning the subduction/accretion/fragmentation of oceanic plateaus at subduction zones and their deformational effects on the overriding island arc-including collision-related arc polarity reversal. Answers to these questions are important for understanding how oceanic plateaus may contribute to growth of continents through time and how subduction zones initiate by polarity reversal.

title: Reprocessed 4-channel seismic data offshore the Nicoya Peninsula, Costa Rica margin, acquired in 2002 during the R/V Melville survey VANC02MV

description: This 2002 Melville cruise, which collected 4-channel MCS data, was part of a multidisciplinary investigation of the thermal state of the subducting lithosphere offshore of the Costa Rica margin. Funded by the U.S. NSF (grants OCE00-01892, OCE00-01941, and OCE00-02031). Its companion cruise, Ticoflux I, was on board the R/V Ewing in 2001. The goals were to determine the comparative thermal state of the subducting lithosphere in these regions, the associated heat and fluid fluxes responsible for the subducting slab thermal states, and how these variables affect subduction zone processes, including chemical flux rates. The data were later reprocessed by Jared Kluesner such that the shot spacing and the CDP (or CMP) spacing (half of channel spacing) is forced to be the same (~30 m), resulting in 4 fold data (4 traces per CDP gather).
