This resiliency is largely dependent on the availability of sand in the beach system. In an effort to better understand the system's sand budget and processes in which this system evolves, high-resolution geophysical mapping of the sea floor in Little Egg Inlet and along the southern end of Long Beach Island near Beach Haven, New Jersey was conducted from May 31 to June 10, 2018, followed by a sea floor sampling survey conducted from October 22 to 23, 2018, as part of a collaborative effort between the U.S. Geological Survey and Stockton University. Multibeam echo sounder bathymetry and backscatter data were collected along 741 kilometers of tracklines (approximately 200 square kilometers) of the coastal sea floor to regionally define its depth and morphology, as well as the type and distribution of sea-floor sediments. Six hundred ninety-two kilometers of seismic-reflection profile data were also collected to define the thickness and structure of sediment deposits in the inlet and offshore. These new data will help inform future management decisions that affect the natural and recreational resources of the area around and offshore of Little Egg Inlet. These mapping surveys provide high-quality data needed to build scientific knowledge of the evolution and behavior of the New Jersey barrier island system. Purpose: This dataset includes the locations and grain-size analysis results of surficial sediments collected with a modified Van Veen grab on the mini-SEABed Observation and Sampling System (SEABOSS) aboard the Research Vessel (R/V) Petrel during USGS field activity 2018-049-FA (October 22-23). The sediments were analyzed at the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center using the HORIBA LA-960 laser diffraction analyzer and sieving of the >= -2-phi fraction. Supplemental_Information: Bottom still images and video were also taken at most sampling sites (see shapefiles 2018-049-FA_photos.shp and 2018-049-FA_VideoLines.shp available from the larger work citation. The sampling data were collected to ground truth (verify) acoustic data collected during USGS field activity 2018-001-FA.

Due to rounding, the sum of the aggregate class percentages (e.g., GRAVEL (wt%), GRAVEL_PCT, etc.) and the sum of the phi fraction percentages (e.g., PHI_11, PHI_10, etc.) may not always add up to exactly 100.000%. Logical_Consistency_Report: The sediment samples were all collected with the same modified Van Veen grab sampler mounted on the mini-SEABOSS. This dataset is based on the final Microsoft Excel spreadsheet received after analysis in the Woods Hole Coastal and Marine Science Center's Sediment Analysis Laboratory. These data were checked but no modifications or corrections have been made to the file. Completeness_Report: All 70 sampling sites were occupied during USGS field activity 2018-049-FA; however, physical sediment samples were only collected at 68 of the 70 sites. There is no sample location for sites 2018-049-FA-026 and 2018-049-FA-047. Sediment samples were only attempted in areas where collecting a sample would not damage the SEABOSS; therefore, no samples were collected in areas with a cobble, boulder, or rocky seabed, as identified in real time using the topside live video feed. Samples were also not attempted if the current was too strong or if the sampler accidentally tripped earlier in the deployment. Each deployment of the sampler is generally considered a unique site; however, three sites (2018-049-FA-005, 2018-049-FA-016, 2018-049-FA-064) had two separate deployments each. The sediment sample locations for these three sites are from the second deployment when a grab sample was successfully collected. Ten samples were randomly selected by the Sediment Lab technician and run as replicates using the laser diffraction analyzer for internal testing purposes. The replicate results are not included in this publication. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The R/V Petrel's Differential GPS (DGPS) system supplied navigation for survey 2018-049-FA. The GPS was set to receive fixes at a one-second interval in geographic coordinates (World Geodetic System of 1984 [WGS 84]). The recorded position of each sediment sample location is the position of the GPS antenna on the survey vessel, located on the aft starboard side of the wheelhouse, not the location of the SEABOSS sampler. The antenna was located approximately 3 meters from the deployment point of the sampler. No layback or offset was applied to the recorded position. In addition, the sampler may drift away from the survey vessel when deployed to the sea floor. Based on the various sources of horizontal offsets, a conservative estimate of the horizontal accuracy of the bottom image locations is 5-7 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The depths recorded for each sample are approximate and were derived from preliminary bathymetry from the geophysical survey 2018-001-FA.

The observations from still and video cameras and the sediment data are used to explore the nature of the sea floor and, in conjunction with high-resolution geophysical data, to make interpretive maps of sedimentary environments and validate acoustic remote sensing data. This configuration of the mini-SEABOSS incorporates a downward-looking SeaViewer HD video camera with a topside feed, two GoPro HERO4 Black cameras recording still images (one was attached to the SEABOSS frame another was extended on a removable pole that was forward of the SEABOSS approximately 1 meter in hopes of getting a clearer, unobstructed view of the seabed), a modified Van Veen sediment grab sampler, and lights to illuminate the seabed for video and photographs. The elements of this particular SEABOSS system are held within a stainless-steel frame that measures 0.9 x 0.9 x 1.25 meters. The frame has two stabilizer fins that orient the system as it drifts over the seabed. Two red lasers were set 20 centimeters apart (both as they are mounted on the SEABOSS frame and as seen in photographs and video on the seabed) for scale measurements. The red laser dots can usually be seen in the imagery depending on the bottom type and distance to the sea floor. The R/V Petrel occupied one of the target stations and the SEABOSS was deployed off the vessel's A-frame on the stern of the ship. The winch operator lowered the sampler until the sea floor was observed in the topside live video feed. The vessel and sampler then drifted with wind and current for up to a few minutes to ensure a decent image with a clear view of the sea floor was acquired. Usually at the end of a short drift, the winch operator lowered the Van Veen sampler until it rested on the sea floor. When the system was raised, the Van Veen sampler closed and collected a sample as it was lifted off the sea floor. The sampler was recovered to the deck of the survey vessel where a subsample was taken for analysis at the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center. The GoPro camera time were set to UTC; calibration photographs with the navigation system indicate that the camera time were off by an average of 5 seconds from the GPS time, so the time offsets were corrected during the geotagging process. During some of the survey, the seabed turbidity made it such that no usable images were able to be acquired. In these cases, brief glimpses of the sea floor may be visible in the coincident video files. Bottom video was recorded from the downward-looking camera directly to hard drives using an Odyssey7 video recorder. The image dimensions of the GoPro photos are 4,000 x 3,000 pixels. The imaged area is most often within 0.5 to 1.25 meters from left to right. DGPS navigation from the R/V Petrel's Hemisphere VS330 GPS receiver was logged to the ship's HYPACK computer (HYPACK version 2017a) and, as a backup, through ArcGIS using the ArcMap GPS extension. The main source of navigation data was the ship's HYPACK files. Process_Step: Process_Description: Seventy stations were occupied aboard the R/V Rafael during USGS survey 2018-049-FA with the mini-SEABOSS (Blackwood and Parolski, 2001). The mini-SEABOSS was equipped with a Van Veen grab sampler, two GoPro HERO4 Black digital cameras, and a downward-looking video camera. Physical sediment samples were collected at 68 of the 70 sampling sites. Sediment samples were only attempted in areas where collecting a sample would not damage the mini-SEABOSS; therefore, no samples were collected in areas with a cobble, boulder, or rocky seabed, as identified in real time using the top-side live video feed. At two sites (2018-049-FA-026 and 2018-049-FA-047), a sample was attempted but was not successfully collected. The sediment sample collection times were recorded in the survey log when the sampler was lifted from the seabed (the Van Veen sampler closed and collected a sample as it was lifted off the sea floor). These manually recorded times would later be used to derive the sample location. Once the sampler was recovered on deck, a subsample was taken for grain-size analysis at the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center. This process step and all subsequent steps were performed by the same person unless otherwise noted.

The DGPS was set to receive fixes at a one-second interval in geographic coordinates (WGS 84). Dates and times were recorded in Coordinated Universal Time (UTC). Sediment sample locations were determined by matching the sampling time recorded in the survey log with the time in the navigation logs using the Python Notebook Grabs_LatLong_NJ2018_HYPACK.ipynb. Approximate depth was derived by extracting the depth values from the preliminary bathymetry data collected during USGS field activity 2018-001-FA (2018001FA_Sept2018_4m.tiff) in QGIS (version 3.4) the Point Sampling Tool plugin. Process_Date: 20181113 Source_Produced_Citation_Abbreviation: Survey log Source_Produced_Citation_Abbreviation: Processed HYPACK navigation files Source_Produced_Citation_Abbreviation: Sediment sample submission spreadsheet Process_Step: Process_Description: Samples submitted to the sediment analysis laboratory for grain size analysis using the Horiba laser diffraction unit (LA-960) and sieving of the ≥ -2 phi fraction are assigned unique analysis identifiers (ANALYSIS_ID) and divided into batches of no more than 30 samples. Each batch is entered into a Microsoft Excel data entry spreadsheet (LD Worksheet Template_xxxx.xlsx, where xxxx is the identifier assigned to the sample submission) to record the initial and dried sample weights, as well as the sieved coarse fraction weights. Each batch is also entered into macro-enabled Microsoft Excel data entry spreadsheets (GrainSizeWorksheet_LD1-30_xxxx(batch_yy).xlsm or GrainSizeWorksheet_LD31-600_xxxx(batch_yy).xlsm, where xxxx is the identifier assigned to the sample submission, 'LD1-30' and 'LD31-60' refer to the pre-labeled and weighed glass laser diffraction vials the samples will be run in, and 'batch_yy' refers to the sample batch) to record the measurement data coming from the laser diffraction unit and incorporate the initial, dried, and sieved weights. About 10-15 grams of wet sediment are placed in a pre-weighed beaker and the gross weight is recorded. The sample is wet sieved through a 4 mm (No. 5) sieve. If there is any coarse fraction remaining in the sieve, the coarse material is oven dried at 100°C in a pre-weighed beaker and weighed again when dry. This coarse fraction is dry sieved to determine the individual weights of the -2 to -5 phi fractions, and the weights are recorded in the data entry spreadsheet LD Worksheet Template_xxxx.xlsx. The fine fraction in water is collected in a pre-labeled and weighed glass laser diffraction vial. If there is any coarse fraction remaining in the sieve from wet sieving, this vial is also oven dried at 100°C and weighed when dry. If there is no coarse fraction remaining from wet sieving, the sample can proceed directly to processing for analyses by the Horiba laser diffraction unit (LA-960). Fine fractions ready for analysis by the Horiba laser diffraction unit are rehydrated with distilled water if they've been dry. Fifteen (15) ml of pre-mixed 40 g/l sodium hexametaphosphate [(NaPO3)6] are added to each sample. If the height of the fluid in the laser diffraction vial is less than 5 cm, more distilled water is added to raise the level to no more than 8 cm in the vial. The samples are gently stirred, covered, and allowed to soak for at least 1 hour (for samples that were not dried) up to 24 hours (for samples that were dried). Soaked vials are placed into an ultrasonic bath and run for 10 minutes at a frequency of 37 Hz with a power level of 100. If the samples appear to be fully disaggregated, they are placed into pre-determined autosampler locations, and are run using the Horiba LA-960 for Windows software to get the fine fraction grain size distributions. The fine fraction distribution data are added to the appropriate data entry spreadsheets (GrainSizeWorksheet_LD1-30_xxxx(batch_yy).xlsm or GrainSizeWorksheet_LD31-600_xxxx(batch_yy).xlsm). The spreadsheet is used to calculate a continuous phi class distribution from the original fractions.

Detailed_Description: Entity_Type: Entity_Type_Label: 2018-049-FA_samples.shp Entity_Type_Definition: Simplified sediment sample analyses in shapefile format created by removing the attribute fields for STDEV, SKEWNESS, KURTOSIS, MEDIAN and other Method of Moments Statistics [e.g. D10], and the individual phi measurements [e.g., PHI_11] from the csv file. Description of the attribute fields remaining in this shapefile are the same as listed for the csv file above. Entity_Type_Definition_Source: U.S. Geological Survey Overview_Description: Entity_and_Attribute_Overview: The shapefile is a simplified version of the CSV file of the laser diffraction analysis results (2018-049-FA_samples_GS-LD.csv) with fewer attribute fields. Specifically, STDEV, SKEWNESS, KURTOSIS, MEDIAN and other Method of Moments Statistics [e.g. D10], the individual phi measurements [e.g., PHI_11], QUALITY_GR and QA/QC_COMM were removed. All the other attributes in the shapefile have the same definitions as the CSV file attributes (see the detailed description section for the 2018-049-FA_samples_GS-LD entity for definitions of the CSV file attributes). The following fields are included in the shapefile: ANALYSIS_I (truncated field name for ANALYSIS_ID), SAMPLE_ID, PROJECT, FAN, SUBMITTER, AREA, SUBMISSION, LATITUDE, LONGITUDE, DEPTH_M, T_DEPTH, B_DEPTH, DEVICE, DATE COLLE (truncated field name for DATE_COLLECTED), ANALYSIS C (truncated field name for ANALYSIS COMPLETION DATE), ANALYSIS M (truncated field name for ANALYSIS METHOD), WEIGHT WET, GRAVEL (wt, SAND (wt %, SILT (wt %, CLAY (wt %, CLASSIFICA (truncated field name for CLASSIFICATION), MEAN, ANALYST, QUALITY GR and QA/QC COMM. If you open the shapefile in ArcGIS software, the field names may be slightly different than described above as the softwares truncate field names differently. ArcGIS will also have two additional attributes, FID and Shape, which have the following descriptions: Attribute: Attribute Label: FID Attribute Definition: Internal feature number.
