2.0 (U) BOTTOM SEDIMENT TYPE DATABASE

(U) This section presents an overview of the structure and contents of the Bottom Sediment Type Database.

2.1 (U) Scope

(U) The Bottom Sediment Type Database describes the sediment type provinces by identifying an integer value that has a one-to-one relationship with a particular sediment type. These descriptors consider the grain size, origin, and placement of bottom deposition. See Section 2.10 for a full description of the database.

2.2 (U) Source

(U) The Bottom Sediment Type data are provided at a high and low spatial resolution. The high-resolution set derives from multiple sources. These include the analyses of grabs and cores collected during surveys conducted by NAVOCEANO, National Imagery and Mapping Agency (NIMA) charts, side scan imagery, seismic, bathymetry, and public literature. See Section 2.10 for additional information.

(U) The low-resolution set is assembled from various high-level sources, including maps, atlases, and regional studies of ocean basins. The data sources are provided below:

2.3 (U) Application

(U) The Bottom Sediment Type Database is provided in four files: Enhanced, Standard, Reduced, and High Frequency Environmental Acoustics (HFEVA). Each file is unique, and it is incumbent upon the user to select the appropriate one based on requirements.

(U) The Enhanced dataset serves as the base-level sediment category set. The Standard, Reduced, and HFEVA files are each derived by reclassification of the Enhanced categories (see Appendix B, Table B-1). The Enhanced file is based on a global set of more than 400 sediment categories. Their derivation is described in Section 2.10. The Enhanced is the actual database that is maintained by NAVOCEANO. It is suitable for researchers and developers with technical geologic knowledge, or in cases where the most detailed geologic information is desired. It is normally not suitable for operational users.

(U) The Standard file is a reclassification of the Enhanced. It consists principally of approximately 30 rationalized sediment grain-size and sediment-mixture categories repeated in two compositional classes, Terrigenous (land-derived particles, primarily composed of silicate minerals) and Carbonate (composed mainly of calcareous minerals created by marine organisms or marine chemical reaction). The Standard sediments are useful when a full spectrum of sediment types with a consistent and comprehensible nomenclature is desired.

(U) The Reduced dataset is also a reclassification of the Enhanced. It employs a simplified classification of 15 categories. The sediment grain-size nomenclature corresponds to the Wentworth grain-size scale as commonly used by geologists and engineers in the United States.

(U) The HFEVA dataset is another reclassification of the Enhanced. It consists of 23 “standard sediment types” based on grain-size and sediment mixtures. These types correspond to a set of six geoacoustic parameters that are inputs to the Comprehensive Acoustic Simulation System/Gaussian Ray Bundle (CASS/GRAB) high-frequency acoustic performance prediction model. The HFEVA dataset is designed specifically for high-frequency acoustic performance prediction. Its use for other purposes is not recommended; users who wish to do so should fully understand the derivation of the HFEVA types.

2.4 (U) Coverage

(U) The Bottom Sediment Type Database covers selected areas throughout the world. The specific areas of the 6-second coverage are shown in Figures 2.4-1 through 2.4-3. The coverage area for the 5-minute resolution data is worldwide (See Figure 2.4-4).

2.5 (U) Resolution

(U) The spatial resolution of the Bottom Sediment Type Database is 1/600º [6 seconds ()] of latitude and longitude and 1/12º [5 minutes ()] of latitude and longitude.

(U) Cautionary Note: The 6-second resolution and the 5-minute resolution data are not merged datasets. Consequently, when extracted, there may be a discontinuity in the sediment provinces at the boundary between two datasets. When extracted, the highest resolution for a given point, trackline, radial, or area will be provided by default.

2.6 (U) Organization

(U) The Bottom Sediment Type Database is stored in a geographic projection organized by sediment category as four separate files: Enhanced, Standard, Reduced, and HFEVA. Each file contains the bottom descriptor integers and a table of the associated category descriptions. The number of categories in the Enhanced dataset have been reclassified to 70, 15, and 23 categories in the Standard, Reduced, and HFEVA datasets, respectively. The user may decide on the level of precision based on the application desired.

(U) The following example demonstrates how the reclassification procedure works. The categories 1228, 1243, 1244, 1245, and 1257 in the Enhanced dataset can all be reclassified to 1212, 62, and 3 in the Standard, Reduced, and HFEVA datasets, respectively.

2.7 (U) Size

(U) The Bottom Sediment Type Database covers approximately 1.1 billion 1/600°-grid cells in each of the four files and 6.5 million 1/12°-grid cells in each of the four files.

(U) All geographic coverages require approximately 545 megabytes of data storage. Table 2.7-1 provides the extraction tool and database file names with their respective sizes.

2.9 (U) Data Storage

(U)The Bottom Sediment Type Database uses the Hierarchical Data Format (HDF), Version 5, Release 1.2.1 (HDF5) for data storage. The HDF includes Input/Output libraries - Application Programming Interfaces (APIs), supported by the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign.

(U) The HDF5 data module is implemented as a file family. This feature allows the family of data files (called members) to be accessed as one logical HDF5 file. HDF5 files are organized in a hierarchical structure of groups and datasets referred to as objects. Access to a group is by way of a pathname. A dataset is a multidimensional array of data elements. Both groups and datasets may have associated attributes.

(U) The Bottom Sediment Type Database is composed of four HDF5 files: Enhanced, Standard, Reduced, and HFEVA. There are two resolutions of sediment data stored within each of the four HDF5 files: a coarse resolution of data at 5.0 minutes and a finer resolution of data at 6.0 seconds. The integer bottom descriptor values are stored in one degree tiles at the lowest level of the database file structure, and the metadata is stored at the higher levels. The associated category descriptions are stored in an internal lookup table. The organization of all files is identical and is illustrated in Figure 2.9-1.

2.10 (U) Data Quality

(U) The Bottom Sediment Type Database is a compilation of sediment information obtained from a world-wide range of sources. Fundamental to the database are nautical chart annotations describing the nature of the seabed. NIMA, National Oceanic and Atmospheric Administration (NOAA), and British Admiralty charts are the principal sources. The chart annotations are augmented with sediment data from open scientific literature (papers published in scientific journals), from technical literature (academic and agency technical reports, theses, and related databases), and from holdings of national and other agencies (e.g., National Geophysical Data Center (NGDC) of NOAA, U.S. Army Corps of Engineers), academic institutions, and from samples collected and processed by NAVOCEANO.

(U) The gathered sediment information exists in a variety of diverse and sometimes incompatible formats. It includes sample point data, areal coverage, and acoustic data.

(U) First-order point data is based on an observation or sample from a unique geographic location. Point data may be a simple verbal description (e.g., “s” for sand, on a nautical chart) to a detailed laboratory grain-size analysis, with its associated technical sediment-property descriptors. Location accuracy of point data varies widely, from chart annotations (in which a chart maker may take some license for positioning an annotation), to samples located with relatively inaccurate and now obsolete navigation methods, to contemporary Global Positioning System- (GPS) located samples. Various geoids employed in the past and in various parts of the world further affect location accuracy.

(U) Second-order areal-coverage data are point data that were previously interpreted and mapped to a specific classification and nomenclature. As such, they are useful in the process of creating sediment provinces, but suffer in that they may not contain the source (point) data.

(U) Sediment classification and the ensuing nomenclature are the core issues in creating a sediment-coverage database of sediment provinces. The NAVOCEANO sediment classification derives from a classification devised by the Joint Oceanographic Institutions for Deep Earth Sampling (JOIDES) Sedimentary Petrology and Physical Properties Panel (SP4) and documented in Ocean Drilling Project (ODP) Technical Note 8: Handbook for Shipboard Sedimentology, 1988. To assimilate the diverse sediment descriptions of the source data and still retain the original descriptions, NAVOCEANO created an “Enhanced” categories set. This set includes virtually all commonly-used sediment nomenclature, including chart annotations, sediment grain-size terminology (Wentworth-scale), sediment-mixture classifications (Shepard, Folk), generic mixtures, as well as depositional environment and compositional descriptors (see Appendix B.1). Consequently, the Enhanced set is large, is in part redundant, and causes ambiguities in nomenclature, but does retain the essence of the source descriptions. For normal operational use, the Enhanced set is rationalized through the creation of simplified, focused sediment category sets, such as Standard, Reduced, and HFEVA and by reclassifying each Enhanced category to the simplified sets.

11UNCLASSIFIED

UNCLASSIFIED

(U) NAVOCEANO has taken the province approach in creating the Bottom Sediment Type Database. Provinces are initially created in the Enhanced category format. The compiled point and coverage data are interpreted and defined into provinces by subject experts. Consideration of source data, data quality, bathymetry, regional geology, relevant geologic and oceanographic processes, and expert knowledge all contribute to province creation.

(U) The province approach represents an attempt to convey, at a base level, what likely is the predominant sediment type over an approximate area. The user must keep in mind that quality of province locations, boundaries, and associated sediment categories will vary considerably depending on the quality and quantity of source data. It is also possible that considerable small-scale variations may occur within provinces, or that provinces are misdefined on the basis of inadequate or erroneous data. The user must also be aware that province descriptors and boundaries are conceptual. Actual sediment variations that define provinces may be gradational, interlaced, and even distinct in some cases. Users who require more accurate, higher-resolution sediment information should request from NAVOCEANO information on additional, newer, or revised datasets that are currently not in OAML. NAVOCEANO acquires and compiles historical and newly collected data, including regional databases, bottom samples, acoustic imagery, and other bottom information on a regular basis.

(U) The 5-minute resolution database provides an estimate of the most likely sediment to be found on a broad, regional basis. Although the database resolution is 5 minutes, the underlying source-data resolution is uneven and far lower, typically by an order of magnitude. Therefore, the database cannot guarantee that the sediment category identified in any cell is absolutely correct, only that the category represents the prevailing sediment within the defined region.

2.14 (U) Extraction/Retrieval

(U) One application is delivered with the Bottom Sediment Type Database to perform data retrievals. The extract program is used to select a sediments database file, set retrieval parameters, and extract data by point, trackline, radial, or area. See Appendix C for a full description of the extract program. Point, trackline, and radial extractions return output to the user’s screen. Area extractions are output to a binary format, known as CHRTR, defined in Table 2.14-1. CHRTR is a gridded file format consisting of header information defining the grid extents and cell size followed by a data value for each cell in that grid. The data values start at the southwest corner of the grid and proceed from west to east, row by row, ending at the northeast corner of the grid.

A.1 (U) Introduction

(U) This appendix describes the inputs and the expected outputs for testing the implementation of the Bottom Sediment Type Database.

(U) This appendix provides the user with five test cases that can verify the correct implementation of the Bottom Sediment Type Database. The data files were generated on a SGI IRIX 6.5 UNIX-based operating system.

(U) Each test case focuses on positions within an area of interest. Four data results are provided for each position. Columns 1 and 2 contain the input latitude and longitude. Columns 3, 4, 5, and 6 indicate the output of the Enhanced, the Standard, the Reduced, and the HFEVA datasets, respectively. The values cited in columns 3, 4, 5, and 6 are associated with the center of a 6-second by 6-second cell.

(U) Reader software is not provided with the data files. See Section 2.14 and Appendix C for data extraction information.

C.1 (U) Introduction

(U) The extract program facilitates data extraction from a geographic area of the database. The program features point, trackline, radial, and area data extraction functions. The user is also provided with options to examine the database metadata and to define database extraction properties. The resolution properties will default to retrieval of the best resolution of data for all extraction requests.

(U) Syntax

extract [database_path] [script_file_path]

where:

database_path (U) This input parameter is the path to the database. If this parameter is missing on the command line, the extract program will prompt for the database path.

script_file_path (U) This input parameter provides the optional script file name that eliminates typing commands at the command prompt. The file path and file name must be provided for the program to locate the script file. The script file should contain the same commands that are typed at the command prompt in interactive mode.

(U) Description

(U) This program enables users to interactively extract the contents of a database. Once the database is opened, the program displays a command prompt and waits for user input unless input is provided from an optional script file. The command prompt displays the database name followed by the % symbol. For example, if the database located at /databases/test.h5 has been opened, the prompt is displayed as:

test.h5%

(U) An overview of command keywords and their descriptions is provided in Table C-1.

C.3 (U) Set Maximum Resolution Extraction Property

(U) Syntax

test.h5 % set maxres new_maxres

(U) Description(U) The maximum resolution property specifies the finest resolution, in minutes, to search for data values. Any resolution finer than the maximum resolution property will be ignored in data extractions. By default, this property is set to the finest resolution in the database.

(U) Example

test.h5% set maxres 0.1

New maximum resolution (minutes): 0.100000

C.4 (U) Set Minimum Resolution Extraction Property

(U) Syntax

test.h5 % set minres new_minres

(U) Description

(U) The minimum resolution specifies the coarsest resolution, in minutes, to search for data values. Any resolution coarser than the minres setting is ignored in data extractions. By default, this property is set to the coarsest resolution in the database.

(U) Example

test.h5% set minres 5.0

New minimum resolution (minutes): 5.000000

C.5 (U) Extract Point

(U) Description

(U) The point extraction command extracts a single data point from the database that is nearest to the x, y position. If the data point is found, the utility will display the security level of the data point.

C.9 (U) Extract Radial

(U) Syntax

test.h5 % radial center_y center_x downtrack_spacing radial_length start_azimuth end_azimuth azimuth_increment

(U) Description

(U) The radial extraction retrieves data points for radials starting at the start azimuth and ending at the end azimuth. Each radial is a geodesic trackline path that begins at the center x, y coordinate, has a length specified by the radial length parameter, and has a direction determined by the current azimuth. See Section C.5 for the coordinate formats. The downtrack_spacing defines the distance between points along the radial tracklines and is expected to be entered in meters. The radial_length defines the trackline length and is also expected in meters.
