Title: Houston Ship Channel 1993-1994
Short Name: Houston Ship Channel 1993-1994
Status: Completed
Abstract:

Between May 5, 1993 and September 19, 1994, we collected quantitative 1-m2 area drop samples and measured a variety of habitat attributes using field surveys and aerial photography to characterize three existing marshes (Atkinson Island, Hog Island, and Cedar Point) in Galveston Bay. We also compared nekton densities among different types of intertidal and shallow subtidal habitats (pond, channel, cove, open bay, and four marsh types). The vegetated surface consistently contained more species and dominant species exhibited at least some degree of habitat selection. To maximize fishery habitat, we recommend placing greater emphasis on constructing low marsh edge habitat by creating large areas of Spartina alterniflora and Scirpus maritimus marsh interspersed with a dense network of shallow channels and interconnected ponds.

Purpose:

The purpose of this study was to document and compare the use by nekton of marsh and adjacent open-water areas within a shallow region of Galveston Bay, Texas.

Data Quality

Accuracy:

Data were entered into spreadsheets and checked against the raw data sheet to avoid entry errors

Quality Control Procedures Employed:

Each sample was assigned a unique identification code. Field collected samples were tagged redundantly (e.g. one label inside container and a matching label attached to outside of container). The sample identifier and associated information (e.g., date, location, habitat) was recorded on the field data sheet. Once a sample arrived at the laboratory, the label remained with the sample throughout the various stages of sample processing. Sample data were entered into an Excel spreadsheet or similar database manager, and the information was printed out and compared against the field data sheets by two biologists. Corrections were made at this time. The electronic file was also sorted and examined by the Lab Supervisor or other project personnel in a variety of ways to look for outliers, missing data, and other potential errors.

Data Management

Have Resources for Management of these Data Been Identified?: No
Approximate Percentage of Budget for these Data Devoted to Data Management: 0
Do these Data Comply with the Data Access Directive?: Yes
Is Access to the Data Limited Based on an Approved Waiver?: Yes
If Distributor (Data Hosting Service) is Needed, Please Indicate: No
Approximate Delay Between Data Collection and Dissemination: 365
If Delay is Longer than Latency of Automated Processing, Indicate Under What Authority Data Access is Delayed:

This data is currently wavered under the current NOAA guidelines for relational databases.

Actual or Planned Long-Term Data Archive Location: To Be Determined
If To Be Determined, Unable to Archive, or No Archiving Intended, Explain:

The archival process is currently under development.

Approximate Delay Between Data Collection and Archiving: 365
How Will the Data Be Protected from Accidental or Malicious Modification or Deletion Prior to Receipt by the Archive?:

The data resides on a secure government network requiring multi-factor authentication for network access.

Lineage

Process Steps

Process Step 1

CC ID: 284903
Description:

After sample collection, field data were entered into an Excel spreadsheet or database file (DBF) using database manager software. A text file was created to describe these data and associated variables. Entered data were checked against the field sheets by two biologists to minimize entry errors. Samples were processed in the laboratory, sorted, specimens identified and measured, and information was entered into an Excel spreadsheet or DBF file. Files were printed out and compared against original data sheets by two biologists for data entry errors. Corrections were made at this time, the electronic file was saved, and a back-up copy made. Hard copies of the QCd files were printed and stored in the project folder along with the original field and laboratory data sheets. The electronic file was also sorted and examined by the Lab Supervisor or other project personnel in a variety of ways to look for outliers, missing data, and other potential errors. Verified data files were then saved electronically on the Galveston Laboratory server and backed-up as needed.
