The DR is maintained as a field unit product, therefore all information and recommendations within this report are considered preliminary unless otherwise noted. The final disposition of survey data is represented in the NOAA nautical chart products. All pertinent records for this survey are archived at the National Centers for Environmental Information (NCEI) and can be retrieved via https://www.ncei.noaa.gov/. Products created during office processing were generated in NAD83 UTM 15N, MLLW. All references to other horizontal or vertical datums in this report are applicable to the processed hydrographic data provided by the field unit.

Roman PE Etrac, Inc. This dataset reflects dredging that was conducted in 2021 outside of the Federal Channel in Berth 8, concurrent to dredging that occured in the Federal Channel under a USACE contract, by the same contractor. There were no products created for this survey. Original survey data was provided as an XYZ file in NAD83 State Plane Texas South Central (usFt) horizontal coordinate system and MLLW (usFt) vertical datum. The XYZ file was transformed to NAD83 UTM15 (meters) using VDatum. This report does not include data acquisition and processing information. All data were reviewed for DTONs and none were identified in this survey. Port Freeport contracted eTrac Inc. and submitted through the Western Gulf Coast NOAA Navigation Manager Multibeam data submission facilitated by Western Gulf Coast (Texas) Navigation Manager Quentin Stubbs from Port Freeport, Texas. No raw data was received with this survey. A 1m grid was generated based on submitted gridded point data atan approximate 2 x 2 ft spacing. The federal channel was updated on the ENC to reflect dredging from 2021, since the USACE data will have been delivered to NOAA via eHydro. The Port of Freeport is eager to see the rest of the dredged area reflected in this dataset (W00722) to be updated on the ENC, to accurately reflect the full extent of the dredging project. This survey does meet charting specifications and is adequate to supersede prior data.
