Description:

Abstract:

CTD (Conductivity Temperature Depth) data were collected offshore of California and Oregon from October to November 2018 during NOAA cruise SH-18-12 on the R/V Bell M. Shimada (USGS field activity 2018-663-FA).
This data release supersedes version 2.0, published in September 2021 at https://doi.org/10.5066/P99DIQZ5. Versioning details are documented in the accompanying VersionHistory_P99MJ096.txt file.

Purpose:

These data were collected as part of the on-going Expanding Pacific Research and Exploration of Submerged Systems (EXPRESS) project, a multi-year, multi-institution cooperative research campaign in deep sea areas of California, Oregon, and Washington, including the continental shelf and slope. EXPRESS data and information are intended to guide wise use of living marine resources and habitats, inform ocean energy and mineral resource decisions, and improve offshore hazard assessments. The ultimate goal of EXPRESS is to develop comprehensive digital elevation models, habitat maps, and geologic maps, which are needed to address important issues associated with marine spatial planning, ecosystem assessments, geohazards, and the impact on sensitive ecosystems of offshore infrastructure development. This particular NOAA cruise focused on deep-sea corals, sponges, and associated habitats.

Data_Set_Credit: Joanne Ferreira, U.S. Geological Survey
Native_Data_Set_Environment:

Raw data from the Sea-Bird SBE 9 CTD were processed using the manufacturers software, Seasave V 7.23.2.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report: The CTD was calibrated according to the Sea-Bird user manual.

Logical_Consistency_Report: No formal logical accuracy tests were conducted.
Completeness_Report:

Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the metadata for each part of this data release carefully for additional details.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. The horizontal accuracy is based on ship's position using the navigations system; MX420 DGPS (Differential GPSP) with an accuracy of 1 m.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

A formal accuracy assessment of the vertical positional information in the data set has not been conducted. Depth was determined using a SeaBird CTD digiquartz pressure sensor with a stated accuracy of 0.015 percent.

Process_Step:

Process_Description:

Conductivity, salinity, and depth (CTD) data were collected with a SeaBird SBE-9 CTD Profile. Data were accumulated into .cnv tab-delimited ASCII text files. Data collected when instruments were out of the water were removed during post-processing. Files are named with a convention that uses a multi-element alphanumeric code delimited by dashes. The first element of this dataset consists of the instrument deployed CTD followed by the number indicating the cast and then the abbreviation for the research vessel (SH for Shimada). The second element is the year of the field activity; the third element the cruise number of the vessel.

Process_Step:

Process_Description:

This data release supersedes version 2.0, published in September 2021 at https://doi.org/10.5066/P99DIQZ5. Versioning details are documented in the accompanying VersionHistory_P99MJ096.txt file. For the revision, this particular metadata file was updated to reflect the new doi number, URLs, download links, and updated PID. No data value changes from ver. 2.0 to ver. 3.0 were made to the CTD data file (SH-18-12_raw_CTD.zip). The metadata available from a harvester may supersede metadata bundled within a download file. Users are advised to compare the metadata dates to determine which metadata file is most recent.
