Item Identification

Title: Sediment Texture
Status: Completed
Publication Date: 2018-08-17
Abstract:

These data show point sample sediment location and texture within the United States Exclusive Economic Zone. This is an aggregate data product compiled from the USGS usSEABED and the East Coast Sediment Texture Database, and NOAA Electronic Navigational Charts. A new generalized texture value was compiled by normalizing across the three input data sets. Additional attributes such as Munsell coloration, grain size, and composition are available in the original sources.
Purpose:

To support ocean planning activities pursuant to the Executive Order Regarding the Ocean Policy to Advance the Economic, Security, and Environmental Interests of the United States, the Energy Policy Act, the National Environmental Policy Act, the Rivers and Harbors Act, and the Coastal Zone Management Act.
Notes:

Previously named Surficial Sediment Classification until 2022-09-15
Supplemental Information:

Bureau Code: 006:48, Program Code: 006:055

Process Steps

Process Step 1

CC ID: 1116821
Description:

Crosswalk schemas from each source into new schema as shown: Layer - (raw attribute that crosswalked to Source) - (raw attribute that crosswalked to Classification) - (raw attribute that crosswalked to AdditionalDescription). ENC - Appropriate portion of SORIND - NATSUR - NATQUA. ECSTDB - created field and populated with "USGS, East Coast Sediment Texture DataBase" - CLASSIFICATION - LITHOLOGY. PAC_EXT and GMX_EXT - created field and populated with "USGS, usSEABED" - SHEPARDCOD - FOLKCODE.
Process Date/Time: 2018-08-12 00:00:00

Process Step 2

CC ID: 1116822
Description:

Delete duplicate features (identical Shape (location) and Classification)
Process Date/Time: 2018-08-15 00:00:00

Process Step 3

CC ID: 1116823
Description:

Merge all Feature classes together
Process Date/Time: 2018-08-13 00:00:00

Process Step 4

CC ID: 1116824
Description:

Merge all ENC feature classes into one
Process Date/Time: 2018-08-09 00:00:00

Process Step 5

CC ID: 1116825
Description:

Select and delete all features that are completely outside the EEZ
Process Date/Time: 2018-08-08 00:00:00

Process Step 6

CC ID: 1116826
Description:

Project all source data into World Mercator
Process Date/Time: 2018-08-07 00:00:00

Process Step 7

CC ID: 1116827
Description:

Create and populate SampleDepth field as shown: Layer - (raw attribute) - (processing steps). ENC - attribute created and populated with "Surface" for all records. ECSTDB - T_DEPTH and B_DEPTH - add new field called "SampleDepth", convert X_DEPTH fields to text and divide by 100 to convert to meters, Concatenate text fields into SampleDepth with " to " between and " meters" at end, select by attribute to replace entries with at least one "-9999" value to "Unknown", select by attribute and replace entries where T_DEPTH and B_DEPTH are equal with "(depth) meters", select by attribute and replace any "0" values with "Surface". PAC_EXT and GMX_EXT - SAMPLETOP and SAMPLEBASE - follow same processing steps as ECSTDB, with exception of dividing by 100 (measurements are already in meters in these datasets).
Process Date/Time: 2018-08-11 00:00:00

Process Step 8

CC ID: 1116828
Description:

Identify ENC duplicates via topology. Delete one feature if category (NATSUR) attribute is the same in both features, or if one is NULL. Otherwise, mark as exception.
Process Date/Time: 2018-08-10 00:00:00

Process Step 9

CC ID: 1116829
Description:
