This grid is a compilation of 8 separate surveys conducted between 2002 and 2013. Data were collected using different vessels and sonars, however, the data were processed and editing using the same methods detailed below.
Process_Step:
Process_Description:
Step 1: Collect data and import multibeam line files into CARIS Hydrographic Information Processing System (HIPS) (versions is year-dependent). Multibeam line files were collected, and processed by onboard USGS personnel during the surveys, except for NF-07-05-CRER and were later archived with NOAA NGDC by NOAA. Basic information about each survey and the surface produces is listed below:
Where:
NGDC Cruise Name= The name assigned by NGDC for the survey if they were NOAA-related surveys.
USGS FAN= The USGS Field Activity Number assigned by USGS Woods Hole Science Center for the survey (if USGS personnel were involved)
Archive= the address of the National Geophysical Data Center archive location where raw data were archived by NGDC after the survey. If data are not archived with NGDC this link is the USGS Field Activity Report that provides basic survey information.
Survey Date= The calendar dates of the survey and data collection by on board USGS personnel.
Output Surface= The name of the final CARIS surface (in .csar format) that was used in the combine function.
Creation Date= the calendar date the latest surface was created for input to the combine function.
If any edits were made to a surface, it is rebuilt, interpolated, and a new creation data is recorded. Format = YYYYMMDD

Process_Description:
Step 2: Import multibeam line files into CARIS HIPS for processing:
This step is the same for all eight surveys in this grid and summarized below. Produced new CARIS HIPS project (version varies depending on year) for each of the eight surveys and imported the line files by Julian day. Line files were recorded using the geographic coordinate system (WGS 84). During the import process a tide elevation of zero was merged into each line and no further tide corrections were applied. Separate Field Sheets were produced in HIPS using the Universal Transverse Mercator (UTM) Coordinate System, Zone 19 (WGS 84). Depth surfaces were produced (150 m resolution) for each survey using all the lines in the survey in the CARIS Spatial ARchive (csar) format. Processing took place during 2002, 2003, 2005, 2007 and 2013.

Process_Description:
Step 3: HIPS editing:
All line files in each survey were reviewed using the HIPS Swath Editor feature to filter and remove inaccurate soundings. Further editing was completed using the 3-D subset editor. Corrections to the speed of sound were applied using the Refraction Editor if required. Finally, the depth surfaces were rebuilt after all editing was complete and interpolated using a 5x5 matrix size and at least 6 neighboring cells.

Step 4: Combine 2003 Ronald Brown surfaces.
Using CARIS Base Editor (v. 4.0.9), the depth surfaces produced from the two 2003 Ronald H. Brown surveys were combined using the "Start Date is Greatest" Criteria. This criteria applied during the combine process puts the surface with the oldest date of data collection on the bottom (RB2003Cube150m_Interp2.csar) and the newest data(RB03_05Cube150m_Interp.csar) on top during the combine function. This combine criteria dictates the cell value that remains when two or more cells overlap from different surfaces.
Note: A complete record of the source surfaces used to produce the final grid (prbathofr150) are in the "PRBathSource.shp" shapefile published in this report.

Using CARIS Base Editor (v. 4.0.9), the depth surfaces produced from the 2002, 2003, and 2006 Ronald H. Brown surveys were combined using the "Start Date is Greatest" Criteria. This criteria applied during the combine process puts the surface with the oldest date of data collection on the bottom (RB2002Cube150m_Interp.csar) and the newest data on top (RB2006Cube150m_Interp.csar) during the combine function.

Using CARIS Base Editor (v. 4.0.9), the depth surfaces produced from the four Ronald H. Brown surveys was combined with the 2005 Hespérides surface using the "Creation Date is Greatest" Criteria. This criteria applied during the combine process puts the surface with the oldest creation date (Hesp05_150mInterp.csar) on the bottom and the surface with newest creation date (RB03_SDIG.csar) data on top during the combine function. This combine criteria dictates the cell value that remains when two or more cells overlap from different surfaces.

Step 7: Final combine
Using CARIS Base Editor (v. 4.0.9), the depth surfaces produced from the Nancy Foster, Nautilus, Ronald H. Brown, and Hespérides surveys were combined using the "Creation Date is Least" Criteria. This criteria applied during the combine process puts the surface with the most recent creation dateRBHesp_150_Interp.csar) on the bottom and the older surface on top (OFR_Nautilus150m.csar)during the combine function. This combine criteria dictates the cell value that remains when two or more cells overlap from different surfaces.

Process_Description:
Edits to the metadata were made to fix any errors that MP v 2.9.32 flagged. 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.). A link in the horizontal accuracy report was changed - the link that was there was no longer valid. The depth resolution value of "unknown" was changed to 9999 to meet standard requirements. Minor fixes to the attribute format for some attributes were needed. 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.
