The University of Puerto Rico Mayagüez - Department of Marine Sciences Isla Magueyes Laboratories staff and director Ernesto Otero provided critical facilities and logistical support during this field activity. The expert seamanship and knowledge of local waters provided by Captain Orlando Espinoza and the crew of the R/V Sultana were instrumental in the success of the program.
This dataset contains source shot, common mid-point (CMP) and trackline navigation, profile images, and stacked SEG-Y trace data for approximately 227 km of multichannel seismic-reflection data collected by the U.S. Geological Survey during USGS field activity 2020-014-FA offshore of southwest Puerto Rico. Images of each seismic profile were generated in order to provide portable and easily viewable alternatives to the SEG-Y versions of the data. Each profile image can be hyperlinked to its corresponding trackline navigation contained within the Esri polyline shapefile '2020-014-FA_MCS_cmpTracklines.shp'. CMP and tick marks along the top of the PNG images correlate to the positions of 500 CMP intervals within the Esri point shapefile '2020-014-FA_MCS_cmp500.shp'. This information allows for spatial correlation of MCS seismic-reflection profiles images with other geophysical and sample data for investigating sea-floor morphology and stratigraphy in the area.
