Data were collected as the RVPS towed a marine sparker sound source along seven depth site transects in water depths ranging between 25 and 600 meters. The R/V San Lorenzo (RVSL; receive vessel) maintained a nearly stationary position at the midpoint along the seven depth site transects and recorded sound with a calibrated hydrophone. Navigation data and survey geometry information are presented in csv format as well as a trackline shapefile. Purpose: This two-vessel survey was designed to quantify the decay of sound emitted from the SIG ELP790 minisparker (powered at 700 joules) and from the Applied Acoustics Delta Sparker (powered at 1.0 and 2.4 kilojoules) as a function of distance during marine geophysical surveys. Seven transect sites were surveyed at five different water depths (25, 50, 100, 200, and 600 meters) to compare the effects of water depth on peak sound level. The source vessel (RVPS) towed the sparker sound source as well as a calibrated hydrophone (TC4034) to record the near-field outgoing signal along the transects. The receive vessel (RVSL) maintained a nearly stationary position at the midpoint of each transect and continuously recorded sound with a calibrated hydrophone (CR3101 or CR3102) at depths between 10 and 20 meters, depending on deployed cable length.

Browse_Graphic_File_Type: PNG Data_Set_Credit: The authors acknowledge our fellow participants of the sparker testing field activity 2021-619-FA (Pete Dal Ferro, Gerry Hatcher, Jared Kluesner, Rachel Marcuson, Jenny McKee, Dan Powers, and Rob Wyland) and our team involved in survey planning and execution (Jackson Currie, William Danforth, Jane Denny, Tim Elfers, Dave Foster, Nathan Miller, Eric Moore, and Carolyn Ruppel). Native_Data_Set_Environment: Navigational data (raw GGA format) were recorded using an Applanix PosMV Elite (https://www.applanix.com/downloads/products/specs/posmv/POS-MV-ELITE.pdf) positioning system . Tektronix SignalExpress software (v. 2015) continuously recorded TDMS files aboard the source vessel (RVPS). Anaconda (v. 4.10.1), Python (v.3.7), Jupyter notebook (v. 6.0.0), and SQLite (version 3.21.0) were used to process the source vessel navigation. Data are presented in csv format as well as a trackline shapefile produced with ArcGIS Pro (version 2.4.1). Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Source vessel (RVPS) navigation files (raw GGA format) were imported and sorted into an SQLite database and the attribute fields were assigned in a Python notebook utilizing the Python tool PyProj.Geod WGS84. Source vessel navigation tracklines are also described in the accompanying shapefile (see 2021-619-FA_RVPS_SrcNavTrackline_shapefile.zip). Logical_Consistency_Report: Quality control was conducted during acquisition and processing to ensure consistency of the vessel position and UTC time of acquisition. Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: An Applanix POS-MV (Position and Orientation System for Marine Vessels) Elite was used to position the source vessel during data collection. The Applanix POS-MV Elite has a stated positional accuracy of 0.5-2 meters (https://www.applanix.com/downloads/products/specs/posmv/POS-MV-ELITE.pdf). Accuracies of final products may be lower due to total propagated uncertainties of the mapping systems, which include position and motion compensation system and navigation error.

Process_Step: Process_Description: Navigation data were acquired using an Applanix PosMV Elite differential Global Positioning System (DGPS) while the source vessel (RVPS) made several passes along seven planned survey tracklines ranging between 25 and 600 meters water depth. A unique code name was given to each navigation line where PS=the source vessel R/V Parke Snavely; L=line followed by 2- or 3-numerals representing the water depth (the water depth may be followed by an A denoting a planned replicate transect line); S=SIG ELP790 700-joule minisparker source, D10=1.0 kilojoule Delta sparker source, or D24=2.4 kilojoule Delta sparker source; subsequent passes are followed with a, b, c, d, and a numeral as needed. Process_Date: 20210427 Process_Step: Process_Description: Navigation data were recorded in raw GGA format. and in a series of Python notebooks the UTC timestamp, latitude, and longitude were extracted. The layback position of the sparker source was calculated to be 20 meters from the stern of the vessel, based on the measured length of the source cable deployed. The Python tool PyProj.Geod WGS84 was used to merge the data frames of the source layback latitude and longitude positions (lbsrc_lat and lbsrc_lon, respectively) and to calculate and assign the offset distance between the position of the sparker source (source layback) and the hydrophone deployed from the nearly stationary receiver vessel (RVSL) for each UTC time sample (utc_dt).
