Danforth, W.W. Foster, D.S. Sherwood, C.R. 2009 1.0 online Open-File Report 2008-1288 Reston, VA U.S. Geological Survey https://pubs.usgs.gov/of/2008/1288/ The USGS Woods Hole Science Center conducted a nearshore geophysical survey offshore of the southern coast of Martha's Vineyard, in the vicinity of the Martha's Vineyard Coastal Observatory (MVCO) in August 2007. This mapping program was part of a larger research effort supporting the Office of Naval Research (ONR) Ripples Directed-Research Initiative (DRI) studies at MVCO by providing data collection and modeling. The geophysical data will be used to provide initial conditions for wave and circulation models for the study area. Ultimately, geophysical mapping, oceanographic measurements and modeling will help to improve our understanding of coastal sediment-transport processes. The geophysical mapping utilized a suite of high-resolution instrumentation to map the surficial sediment distribution, depth and sub-surface geology: dual-frequency 100/500 KHz sidescan-sonar system, 234-KHz interferometric sonar, and 500 Hz -12 KHz chirp sub-bottom profiler. The survey was conducted aboard the M/V Megan Miller August 9-13, 2007. The study area covers 35 square kilometers from about 0.2 km to 5-km offshore of the south shore of Martha's Vineyard, and ranges in depth from ~ 5 to 20 meters. This sample data set is used to support the Office of Naval Research (ONR) OASIS (optical and acoustic sediments in situ) and Ripples Directed Research Initiative (DRI) projects near the Martha's Vineyard Coastal Observatory (MVCO). Specifically, sample data were collected to mark the boundary between coarse and fine sediment prior to deployment of instrumented tripods, after retrieval of tripods, and to document physical characteristics of the beach.

Warner, J.C. 2009 online Woods Hole, MA U.S. Geological Survey https://woodshole.er.usgs.gov/project-pages/sediment-transport/ Onshore beach samples were collected within approximately 0.5 kilometers of the MVCO Meteorological Mast in September 2005. Seafloor samples were collected in the vicinity of the Martha's Vineyard Coastal Observatory (MVCO) 12-meter node and ASIT in August and October 2007. Beach samples were collected by hand, seafloor samples were collected by SCUBA divers using short (30-cm) push cores or by Van Veen grab sampler. All samples were processed by the U.S. Geological Survey sediment laboratory. All sample data collected in September 2005, August and October, 2007 are included in this ESRI shapefile. Navigation was provided by the R/V Connecticuts GPS system for samples collected in August and October 2007, (http://www.marinesciences.uconn.edu/MSTC/Vesselops/rv_specs.html). GPS (no Selective Availability) is considered to provide roughly 10 meters positional accuracy (http://www.navcen.uscg.gov). The location of beach samples was estimated from Google Earth images (2005). Water depth of sample locations were recorded from the ship's echosounder to provide a general depth for each sample. Nominal depth (meters, relative to MLLW, probably accurate to +/- 1 m). Information unavailable from original metadata - assumed USGS unknown Information unavailable from original metadata 2009 publication date Information unavailable from original metadata In August, 2007 USGS deployed instrumented tripods at two locations within the geophysical survey area. Prior to tripod deployment, seafloor sediment samples were collected at the tripod locations, to define the boundary between coarse and fine sediment. The sample locations were dictated by the investigative needs of the OASIS (optical and acoustic sediments in situ) and DRI projects, and were not collected to ground-truth the 2007 geophysical survey area. In October, 2007 the tripods were recovered and additional sample locations were collected. Beach samples collected in 2005 are also included. All samples were processed for grain size in the WHSC sediment lab using sieve and coulter counter techniques (Poppe, and others, 2005). Beach samples (top 2 cm) were hand-sampled with a Teflon-coated scoop. Most other samples were obtained by SCUBA divers with short (~15 to 30-cm long x 4.5-cm diameter) push cores, but a few were collected with a modified Van Veen grab sampler and subsampled to obtain representative material from the top 2 cm. Samples were collected in September, 2005 and August and October, 2007. Only samples collected in August, 2007 are associated with a USGS, Woods Hole Science Center, Field Activity Number (07028). Sediment sizes are reported in phi units, which are defined as: size [phi] = -log2( size [mm] ). Beach samples were obtained by R. Horwitz. USGS diver samples were obtained by D. Blackwood and C. Worley. Samples were also provided by A. Hay (Dalhousie University) and P. Traykovski (WHOI). Sample analyses were performed by K. McMullen. A Microsoft Excel 2004 spreadsheet containing sediment analysis and additional acquisition information was exported as a comma-delimited text file (*.csv). The comma-delimited text file was then imported to ArcGIS 9.2 using Tools - Add XY Data, creating an event theme referenced to the Geographic Coordinate System WGS84. The event theme was then exported as a point shapefile. 2009 Jane F. Denny U.S. Geological Survey Geologist mailing and physical address

This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Reordered the links in the identification section so a landing page link is first. Attempted to modify http to https where appropriate. The source information was incomplete and had to be modified to meet the standard. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent. 20171019 U.S. Geological Survey VeeAnn A. Cross Marine Geologist Mailing and Physical

The key for the other samples is: First letter C or F indicates coarse or fine sediment patch, D indicates dividing line between coarse and fine at the USGS 11-m site. Two-digit number 08, 11, 12, 16 indicates nominal water depth (meters, relative to MLW). Next letter C or T (if present) indicates location of sample on crest or trough of a ripple. Final letter T or B (if present) indicates top or bottom of diver push core. Column B FIELD_NO This column contains the original sample information recorded in the field. In some cases, it includes a date and a sample number; in others, it provides more information on sample location. In the case of the beach samples, KB indicates Katama Beach. Sediment samples were collected on south-facing Katama Beach in Edgartown, MA on September 16, 2005. Samples were collected in three parallel transects, roughly 5m apart. Each transect started at the base of the dune and ran to the low-tide water level (12:50pm EDT), totaling 7 samples at 5m intervals, zero to 30 meters from the dune base. Samples at 0m are labeled dune then +5, +10, +15, etc. The second number identifies the transect, with transect 1 farthest west. Definitions of the fields within the sediment sample shapefile were provided by Chris R. Sherwood, USGS. Jane Denny U.S. Geological Survey Geologist mailing and physical address
