66197 Data Set Published / External 37232 MarineCadastre Project Completed 2018-08-17 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. 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.

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. 2018-08-12T00:00:00 2 Delete duplicate features (identical Shape (location) and Classification) 2018-08-15T00:00:00 3 Merge all Feature classes together 2018-08-13T00:00:00 4 Merge all ENC feature classes into one 2018-08-09T00:00:00 5 Select and delete all features that are completely outside the EEZ 2018-08-08T00:00:00 6 Project all source data into World Mercator 2018-08-07T00:00:00 7 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). 2018-08-11T00:00:00 8 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. 2018-08-10T00:00:00 9 Delete all records that lack a meaningful value in both Classification and Description. 2018-08-14T00:00:00 66198 Entity gov.noaa.nmfs.inport:66197 Brianna Key 2021-12-22T05:39:15 SysAdmin InPortAdmin 2025-05-15T19:16:13 2021-12-22 Office for Coastal Management OCM 1002 Public No No 2021-12-22 1 Year 2022-12-22
