Description:
Abstract:
In summer 2014, the U.S. Geological Survey conducted a 21-day geophysical program in deep water along the Atlantic continental margin by using R/V Marcus G. Langseth (Field Activity Number 2014-011-FA). The purpose of the seismic program was to collect multichannel seismic reflection and refraction data to determine sediment thickness. These data enable the United States to delineate its Extended Continental Shelf (ECS) along the Atlantic margin. The same data can also be used to understand large submarine landslides and therefore assess their potential tsunami hazard for infrastructure and communities living along the eastern seaboard. Supporting geophysical data were collected as marine magnetic data, gravity data, 3.5-kilohertz shallow seismic reflections, multibeam echo sounder bathymetry, and multibeam backscatter. 
The survey was conducted from water depths of approximately 1,500 meters to abyssal seafloor depths greater than 5,000 meters. Approximately 2,761 kilometers of multi-channel seismic data was collected along with 30 sonobuoy profiles.
This field program had two primary objectives: (1) to collect some of the data necessary to establish the outer limits of the U.S. Continental Shelf, or Extended Continental Shelf, as defined by Article 76 of the United Nations Convention of the Law of the Sea and (2) to study the sudden mass transport of sediments down the continental margin as submarine landslides that pose potential tsunamigenic hazards to the Atlantic and Caribbean coastal communities.
Purpose:
This shapefile contains common mid-point (cmp) navigation for approximately 2,761 kilometers of multi-channel seismic data collected by the U.S. Geological Survey during USGS survey 2014-04-FA. These data were collected off the U.S. Seaboard Atlantic as part of the U.S. Extended Continental Shelf project and investigations of tsunami hazards. The unique common mid-point (cmp) navigation is generally used to aid in interpretation. The common mid-point (cmp) navigation allows features in the seismic data to be correlated to features visible within coincident geophysical data.

Data_Quality_Information:
Logical_Consistency_Report:
Field work is inherently unpredictable, and the original cruise plan was modified to accommodate a hurricane, a medical evacuation, and extreme feathering of the streamer due to the Gulf Stream. While the original cruise plan identified sequentially numbered cruise tracks, interruptions to data collection necessitated the renaming and renumbering of seismic lines to include A and B segments, and the exclusion of lower-priority lines (like 4 and 5). Regardless of name, seismic lines were collected in a consistent manner.
Although data quality was in general excellent, there are several known problems with the data, including noisy channels (up to 71 channels out of 636 in the 8-km configuration, and 65 channels out of 480 in the 6-km configuration), extreme feathering of the streamer on lines which crossed the Gulf Stream, occasional reduced source size for maintenance on the airgun strings, and one 12-minute power down for a protected species. Rough weather also produced wave noise on the streamer. The events, and timing of these events are too numerous to list here, and the logs archived on the Rolling Deck to Repository Archive system (http://www.rvdata.us/catalog/MGL1407) should be referenced for the exact timing of events effecting the quality of the data presented here.
Completeness_Report:
This shapefile contains common mid-point (cmp) navigation for all of the multi-channel seismic data collected during USGS field activity 2014-011-FA. 16 multi-channel seismic lines were collected in total, and the lines are not sequentially numbered, and some lines are partitioned into A and B sections.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Navigation was acquired using the R/V Marcus G. Langseth's fully integrated multicomponent navigation system, consisting of echosounder, speedlog, Differential Global Positioning System (DGPS), gyrocompass, POS/MV Integrated Navigation System, Kongsberg Seapath 200 Inertial Navigation System and Lamont Data Systems (LDS) data logger. All survey positions use the World Geodetic System 1984 datum (WGS84), and both global and local geodetic calculations utilized the WGS84 reference ellipsoid with a semi-major axis of 6378137.0 m and an inverse flattening of 298.257224. Streamer geometry calculations were performed in Universal Transverse Mercator (UTM) northern hemisphere projection 19 North . Water bottom topography in stacked sections agrees well with multi beam bathymetry data gridded to 50 m, implying that these CMP locations are accurate to <50m.

Multi-channel seismic data were acquired with a 36-element, 6600 cubic inch airgun source array, and 8-km-long solid state digital hydrophone streamer towed behind the R/V Marcus G. Langseth. The source air guns were configured in four parallel, 9-gun strings and towed at the rear of the ship at a depth of 9 meters. The Sentry Solid Streamer Sercel hydrophone cable consists of 12 hydrophones, which are summed in analog, and the spacing between the center of these groups is 12.5 m. Streamer depth was set to 9 m for all lines. Approximately 2,761 km of data were collected. Data were recorded at a 4-millisecond (ms) sample rate and in Society of Exploration Geophysicists D (SEG-D) format.
Source and receiver positions were determined by LDEO staff using Concept Systems's Spectra multichannel seismic navigation software. Source positions were logged using differential GPS antennas on three of the four source sub arrays. Receiver positions were calculated using data from Digicourse Digirange acoustic pods on the source array and on the head, middle, and tail of the streamer; depth and heading data from Digicourse depth control birds located every 300 m along the streamer; and a differential GPS on the streamer tail buoy. All survey positions use the World Geodetic System 1984 datum (WGS84), and both global and local geodetic calculations utilized the WGS84 reference ellipsoid with a semi-major axis of 6378137.0 m and an inverse flattening of 298.257224.

Streamer geometry calculations were performed in Universal Transverse Mercator (UTM) northern hemisphere projection 19 North . Source-receiver midpoints were calculated using source and receiver positions from the processed P190 seismic navigation. All midpoint and bin calculations were made in UTM 19N coordinates using Shearwater’s OpenCPS (version 3.3.0) seismic processing software. To handle extreme streamer feathering, CMP bin assignments were made using 1000-m wide rectangular bins spaced every 6.25m along prescribed CMP lines. Midpoints that fall outside these 6.25x1000m bins were assigned CMP=0 and were excluded from processing. CMP lines were drawn to maximize the number of midpoints from source-receiver offsets of <1000m in each bin (i.e., fold).

Process_Description:
SEG-D format shot gathers were imported into OpenCPS (version 3.3.0) software, and processed through a standard sequence of trace editing, common-midpoint (CMP) sorting, bandpass filtering, deconvolution, velocity analysis, normal moveout correction, stretch muting, stacking, and post-stack time migration. True group and source locations were taken from the P190 navigation files provided by the crew of the R/V Marcus Langseth. Files were written to SEG-Y format using OpenCPS (version 3.3.0) seismic proicessing software. Processing step specifics are written into the SEG-Y text header for each line:

Process_Step:
Process_Description:
Coordinates were converted to Universal Transverse Mercator (UTM) northern hemisphere projection 19 North for streamer geometry calculations (calculation of cmp position). While the data extends beyond the singular UTM Zone 19N, the selected UTM zone is central to the majority of the data. Projected coordinates are often used for binning, and CMP calculation as the units (meters) are easier to use than fractional degrees of latitude and longitude. CMP locations were converted back to geographic coordinates. CMP locations were written as geographic coordinates (WGS84) to a text file (*.csv) using a Python script within OpenCPS (version 3.3.0) , and then imported into Esri ArcMap 10.3 using ArcCatalog, Create Feature Class from XY Table, specifying geographic coordinates, WGS84 coordinate system (EPSG code 4326).
