title: Processed multichannel seismic data along the southern Alaskan margin, acquired during the R/V Maurice Ewing survey EW0408 (2004)

description: As part of a site survey for a proposed IODP program to drill marine sediments associated with late Cenozoic climate change and tectonic activity along the southern Alaskan margin, the researchers combined efforts with an already funded piston coring and shallow imaging cruise. The purpose was to acquire additional piston cores and high-resolution seismic images at proposed Gulf of Alaska drill sites. The marine seismic data is to be used in sequence stratigraphic correlations and baseline characterization of the proposed IODP drill sites. Funded by NSF grants OCE02-41828, OCE02-42084, OCE03-51043, OCE03-51062, OCE03-51075, OCE03-51089, OCE03-51096, OCE03-51620, and OCE04-55183.

title: Processed multichannel seismic data across the Chicxulub impact structure on the Yucatan Peninsula, Mexico, acquired during the R/V Maurice Ewing survey EW0501 (2005)

description: This combined reflection-refraction seismic experiment was a joint project between UTIG, University of Arizona, Imperial College (UK), Cambridge University (UK), UNAM (Mexico), and CICY (Mexico). The goals were: 1) to determine the direction of approach and angle of the Chicxulub impact as modeling has shown that a 15-20 time greater amount of airborne particles are produced by low-angle impacts; 2) to map the deformation (faults and broken rock) recorded in the upper crust near the crater center that may explain the way the surface of the Earth is damaged by large meteor or comet impacts; 3) to image the key features in the northwest portion of the crater to enable better understanding of the Chicxulub impact structure and prepare for possible future sampling to examine the melted and shattered rocks deep within the crater; 4) to model the 3-D collapse of the crater to examine both the deformation and the environmental effects of the impact to better understand how such an impact can cause worldwide mass extinctions. Funded by NSF grants OCE02-21101 and OCE02-20474, the Natural Environment Research Council, UK, and the Universidad Nacional Autonoma de Mexico.

title: Broadband ocean bottom seismometer (BBOBS) data, off North Carolina, acquired during R/V Marcus G. Langseth expedition MGL1408 (2014) as part of the Eastern North America Community Seismic Experiment (ENAM CSE)

description: Part of the Eastern North America Community Seismic Experiment (ENAM), broadband ocean bottom seismometers (BBOBS) were deployed and recovered during R/V Endeavor cruises EN537 and EN544. This experiment augments the Earthscope Transportable Array (TA) with 30 broadband ocean bottom seismometers (OBS) spanning a 400 x 500 km area offshore North Carolina, with three addition onshore broadband stations on the Outer Banks to span the gap between the TA and the OBS network. The seismometers recorded the airgun shots from the 2014 R/V Langseth expedition (MGL1408) as it collected MCS data off North Carolina and Virginia while the R/V Endeavor (EN546) collected OBS data. The goal was to collect data to image geological structures beneath the seafloor to learn about the evolution of continental margins and their geohazards. Funding was provided by NSF grants OCE13-47498, OCE13-48454, OCE13-48124, OCE13-48342, OCE13-48228, and OCE13-47310. Notes: Only the geophone part (not hydrophone) of the data were archived. Data from BBOBS station B01 were not archived. The data in this dataset are in conventional SEG-Y format. All of the ENAM seismic data that has been archived as SEED at the IRIS DMC has been assigned a separate DOI and can be accessed via the landing page, http://www.fdsn.org/networks/detail/YO_2014/ .

title: Processed multichannel seismic data at 14 degrees 15'S along the East Pacific Rise south of Garrett Fracture Zone, acquired during the R/V Maurice Ewing survey EW9102 (1991)

description: This Two-ship Experiment on a Ridge Axis (TERA) provided the first detailed geophysical constraints on the crustal structure along the East Pacific Rise south of the Garrett fracture zone, a major focus of the RIDGE initiative. The R/V Maurice Ewing&lt; and Thomas Washington (TERA01WT) were to collect three types of data: (1) 20 closely-space, single-ship multichannel seismic reflection profiles along the EPR; (2) 25 two-ship expanding spread profiles along and parallel to the rise axis in this same area; and (3) a 700-km-long multichanel seismic reflection profile along the EPR from the Garrett fracture zone to the large overlapping spreading center at 20.5S. The objectives were to use these data to test the spreading rate dependence of magma chamber size; to examine the relationship between crustal magma chambers and along-axis changes in morphology, segmentation and basalt geochemistry; and to resolve better how the first-order seismic structure of oceanic crust, including Moho and seismic layer 3, developed during the first few hundred thousand years after crustal formation.

title: Processed multichannel seismic data in the Woodlark Basin and D'Entrecasteaux Islands region, off Papua New Guinea, acquired during the R/V Maurice Ewing survey EW9203 (1992)

description: This was a study of the extensional mechanisms in the Woodlark basin where westward propagation of seafloor spreading is accompanied by active continental extension in the D'Entrecasteaux islands and flanking basins immediately landward of the propagator. The overall objective was to investigate continental breakup and initiation of seafloor spreading in a region where it is presently active. The aims of the project were to determine: (1) whether intra-continental extension is occurring along low-angle detachment faults or normal faults, (2) whether seismogenic faults can be correlated with faults observed in the seismic sections, (3) the whole crustal geometry of structures that bound the core complexed of Goodenough and Fergusson islands, and (4) whether the transition from intra-continental extension through to continental breadup reflect an evolution of extensional mechanisms. Data collection was funded by NSF grant OCE90-12730. Processing of this data set was funded by NSF OCE 0525671.

title: Processed multichannel seismic data in the Bering and Chukchi seas off Alaska, acquired during the R/V Maurice Ewing survey EW9410 (1994)

description: Stanford University, in conjunction with the U.S. Geological Survey, and with participation by the Institute of the Lithosphere and the Institute of the Russian Academy of Sciences, and the Geodynamics Research Institute of Texas A and M University, conducted deep seismic investigations of the continental crust beneath the Bering and Chukchi Seas, Alaska, during the month of August, 1994. The data was recorded to two-way travel-times of 15 to 23 seconds, with 50-75 m shot spacing. Two north-south transects were profiled. The eastern transect extended from 58 degrees 50'N, 168 degrees 32'W, well within the continental shelf of the Bering Sea, north of the Pribilof Islands, to just south of the shelf edge north of Barrow, Alaska, at 71 degrees 49'N, 154 degrees 33'W. Ice prevented continuation of the line beyond the shelf edge. The western transect extended from the central Chukchi Sea, well within the shelf at 71 degrees 23'N, 163 degrees 00'W, into the Aleutian basin at 58 degrees 00'N, 178 degrees 30'W, near Navarinsky Canyon. An additional short line crossing over the Beringian margin a second time was recorded near Zemchung Canyon east of the western transect. The profiles cross important strike-slip faults, possible terrane boundaries, two continental margins, and several Cretaceous/Tertiary sedimentary basins (Norton, Hope, Chukchi, and Navarin Basins). Together with the preceding cruise EW9409, the profiles provide a continuous transect across the North American continent, from the Pacific to Arctic Ocean. Most of the multi-channel (MCS) data is of high quality, but bad weather, strong currents, and recording problems sometimes presented difficulties during data acquisition. Gravity, magnetic, and sonobuoy data were also recorded along the profiles. Wide-angle recording was done in conjunction with the seismic profiling, at recording sites located along the central west coast of Alaska and the Chukchi Peninsula, as well as on islands in the Bering Strait and Bering Sea. The purpose was to conduct deep seismic investigations of the continental crust beneath the Bering and Chukchi Seas. Funded by NSF grant OCE93-17087.
