title: COAST: Heat flow derived from Bottom Simulating Reflectors (BSR) at the Cascadia Subduction Zone (investigators H. Paul Johnson, Evan Solomon, Robert Harris, Marie Salmi)

description: This heat flow data set was derived from Bottom Simulating Reflectors (BSR) imaged using active-source multi-channel seismic data acquired during the Cascadia Open Access Seismic Transects (COAST) survey conducted in 2012 along the Southern Cascadia Margin during R/V Langseth expedition MGL1212. The heat flow data and processing steps are described in Salmi et al., 2017. From each multi-channel seismic profile, the seafloor and BSR travel times were picked, and assuming 50% lithostatic/hydrostatic pressure and normal saline water, the temperatures were estimated. Thermal conductivity was assumed to follow the relationship provided by Davis et al., 1990 which correlates well with borehole data off Vancouver Island. The data file is in ASCII format and contains individual profile line number, common depth point (CDP), latitude, longitude, heat flow and its uncertainty, and seafloor depth derived from multibeam bathymetry also collected during cruise MGL1212. Funding was provided by NSF grants OCE11-44164 and OCE12-49552. Raw geophysical and seismic data can be downloaded from the Lamont-Doherty Earth Observatory Web site (http://www.marine-geo.org/tools/search/entry.php?id=MGL1212). Seismic profiles processed shipboard through post-stack time migration can be downloaded from the University of Texas Institute for Geophysics seismic database (http://www-udc.ig.utexas.edu/sdc/cruise.php?cruiseIn=mgl1212).

title: Southwest Indian Ridge mantle Bouguer and residual mantle Bouguer gravity anomaly data (netCDF format) between 61°-67°E

description: Off-axis geophysical surveys provide a 26-m.y.-long record of axial tectonic and magmatic processes over a 660-km-long and melt poor portion of the ultraslow Southwest Indian Ridge. The data reveal a new type of seafloor (the smooth seafloor) that forms at minimal ridge melt supply, with little or no axial volcanism. The gravity data were primarily collected during Marion Dufresne cruise 135 in 2003 (https://campagnes.flotteoceanographique.fr/campagnes/3200080/). Details of the processing of the gravity data are provided in the Supplement Material section of Cannat et al. (2006). The residual mantle Bouguer anomaly (RMBA) was calculated from free-air ship gravity data by first subtracting the effect of topography of a constant crustal thickness (3.4 km; the mean seismic crustal thickness determined near 66°E (Muller et al., 1999)), constant density (2700 kg/m3) crust, and then the effect of upper mantle cooling with age (using magnetic anomaly picks). The thermal correction model assumes a simple square root of age mantle cooling law (Parsons and Sclater, 1977). The thermal model was cut off 25 km off-axis, and a constant temperature gradient used in the intervening axial region. The data files are in GMT-compatible netCDF grid format. The "mba" grid is the mantle Bouguer anomaly data and the "rmba" grid is the residual mantle Bouguer anomaly grid.

title: Processed PROBE multi-channel seismic dip and strike profiles acquired in 1986-1987 along the Lake Malawi (Nyasa) Rift

description: There are 28 Multi-Channel Seismic lines, collected in 1986/87 across the Central and South Basins of the Lake Malawi Rift as part of the PROBE project (Proto-Rifts and Oceanic Basin Evolution) of Duke University. All files are in SEG-Y format, with coordinate reference system and navigation information in the headers. The projection is UTM-36S. The record length is 6 seconds two-way travel time, 4 ms sample rate. Profiles are generally oriented east-west across multiple rift segments. Data were acquired aboard R/V Nyanja, a 36-foot-long dedicated geophysical vessel transportable by cargo aircraft. Source was a single 140 cubic inch EERI airgun, or 3x40 cubic inch array of GSI sleeve guns. Streamer was a GECO custom-built 960 m active-length cable comprising 48 groups (20 m group interval); lead-in cable length varied from 250-440 m. Streamer depth was nominally 10 m and controlled a buoy suspension system. Fold coverage was nominally 24-fold. Acquisition was via Texas Instruments DFS-V, at 2 ms sample rate. Navigation was by transit satellite, radar, automatic speed log and deduced reckoning. Navigational accuracy ranges from &lt;100 m to several km in places. Every line is controlled by a minimum of two fixes and a 40-80 km line is controlled by 5-8 good fixes. Chief Scientist was Bruce R. Rosendahl. Data were recovered from 9-track tape and archived on modern media under the supervision of Christopher A. Scholz, Syracuse University. Legacy time processing at Duke University was completed with Digicon DISCO 50 software on a DEC VAX 11/750 computer, applying the following workflow: Demultiplexing, Resample, Geometry Definition, Trace Edit, Sort, Deconvolution, Filter, Velocity Analysis, Stacking, Mute, Migration, Display. Deconvolution is a predictive gap deconvolution, occasionally spiking deconvolution is used. Filtering was variable, typically a bandpass filter with a Hanning taper was employed with typical cutoffs of 6-10 Hz at the low end, and 50-55 Hz at the upper end. Some lines received time-variant filtering and occasionally notch filters were used. Select lines were subjected to a post-stack finite difference time migration routine. Funding for data collection and processing was from multiple 1980s-era oil and gas companies.
