Data Set Information

Data Set Scope Code: Data Set
Data Set Type: Files
Maintenance Frequency: Continually
Data Presentation Form: Table (digital)
Entity Attribute Overview:

Water column sonar data are collected by active acoustic (or sonar) technology and contain acoustic scattering information from the near-surface to the seafloor. Scientists use these data to assess physical and biological characteristics of the ocean, including the spatial distribution of plankton, fish, methane seeps, and underwater oil plumes.

Technical Environment

Description:

A variety of sonars are used by the data providers with Kongsberg's EM 122 (12 kHz) and EM 302 (30 kHz), Simrad's EK60 (18-710 kHz, split beam), and ME 70 (70-120 kHz, can be split beam) being most common. The configuration of each cruise's sonar system (e.g., beam type and angle) can be found in the file metadata.

Data Quality

Quality Control Procedures Employed:

Data includes links to sonar calibration files, sound velocity profiles and CTD data.

Data Management

Have Resources for Management of these Data Been Identified?: Yes
Approximate Percentage of Budget for these Data Devoted to Data Management: Unknown
Do these Data Comply with the Data Access Directive?: Yes
Is Access to the Data Limited Based on an Approved Waiver?: No
If Distributor (Data Hosting Service) is Needed, Please Indicate: No
Approximate Delay Between Data Collection and Dissemination: 90 Days
Actual or Planned Long-Term Data Archive Location: NCEI-CO
Approximate Delay Between Data Collection and Archiving: 90 Days
How Will the Data Be Protected from Accidental or Malicious Modification or Deletion Prior to Receipt by the Archive?:

Prior to submission, data are packaged using a data packager script, which combines metadata and data files with appropriate QC checks.

Lineage

Process Steps

Process Step 1

CC ID: 215982
Description:

The data provider uses the WCSD Packager to create a Data Package from the Instrument Files and/or user entered cruise and instrument details.

Process Step 2

CC ID: 215983
Description:

The Data Package is sent to the WCSD Data Manager at NCEI in Colorado who ingests the data for archiving.
