Step 1. This step is the same for all surveys included in this grid except as noted for RB0904, NF-11-04-NC, MGL1512, NF1208_USGS, H12490, and H12491. Downloaded the raw data files from the National Centers for Environmental Information (NCEI) for each survey listed below. Line files are archived in the geographic coordinate system and loaded into CARIS HIPS (v. 7.1-9.0, Software was updated as new versions were available over the course of this project). All surfaces created in HIPS used a 100 meter grid cell resolution and the Mercator projection with a central longitude of 72.0 degrees West, and a latitude of true scale of 45.0 degrees North that is more suitable for the spatial extent of this project than the geographic coordinate system.
Where:
Survey=Cruise Name
Source=the address of the National Centers for Environmental Information archive location where raw data were downloaded.
Download Date=The calendar date the raw data were downloaded.
Download Format= the version of MB-System format of the data downloaded.
Output Surface= The name of the final CARIS surface (in .csar format) that was used in the combine function.
Surface 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
Surveys in Version 1 (ambath100) that are included in Version 2 (AMBath100m_V2.tiff). These data are included in "AtlanticMarginOFRBath100m5Feb13.csar" described in processing step 7 below.
VERSION EXPLANATION:
The follwing surveys are included in Version 1 of this grid, but were superceded with newer, higher resolution dat in Version 2: B00218, B00219, B00220, B00308, B00309.
The Surveys listed below were included in Version 1 and are also included in Version 2. Some of the surveys were updated for version 2 to either include additional lines from the same survey, that are now with in the larger extent covered by version 2, or further edited to improve data quality. An explantion of updated surfaces are included with each updated entry below.
