Title:
Compass Port Baseline Marine Surveys: A Time-Series of Hydrographic and Current Data from a Permanent Moored Station Outside Mobile Bay (2004-2006)
Description:
Abstract:
In 2004 Compass Port LLC (Compass Port) and the Dauphin Island Sea Lab (DISL), in consultation with NOAA, developed a research plan to assess the possible ecological impacts of the proposed Compass Port liquefied natural gas (LNG) facility in lease block MO910, approximately 18 km south of Dauphin Island. As part of the overall baseline survey, a mooring was established at 30 05.410'N 88 12.694'W to collect time-series hydrographic and current data. Instruments included a vertical array of thermisters, CTDs at surface and bottom, and an ADCP at the bottom. Temperature, salinity, density, depth, and current velocity data were collected at 20-minute intervals from 2004 to 2006. Other parameters, such as dissolved oxygen, are available for portions of the time series beginning 20050215.
Purpose:
The study was designed to provide baseline information for the project area prior to construction of the proposed facility, and use the baseline information to develop an operational biological and physical monitoring program to ascertain whether predicted impacts would actually occur.
Supplemental_Information:
Compass Port LLC withdrew their proposal and ceased funding the study in 2006. However, the mooring continued to operate and collect data under DISL's FOCAL program, funded by the Alabama Department of Conservation and Natural Resources, Marine Resources Division, from 2006 to 2012. The mooring is still in operation on a shoestring budget.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Only the most preliminary QA/QC was performed on the data. Users are responsible for conducting their own QA/QC according to the needs and parameters of their particular study. For the ADCP data, four error flags are provided for each value (see EMCP in the Entity/Attributes section). In addition, pitch and roll flags (how far the ADCP was from a vertical position) are available in a separate document.
Logical_Consistency_Report:
N/A
Completeness_Report:
The vertical array consists of a surface CTD (located 4.33 m below surface), 5-10 thermisters (temperature only) spaced at mostly regular intervals through the 20 m water column, a bottom CTD, and an ADCP. A YSI for collecting near-bottom oxygen data was present for portions of the time series, beginning 20050215. Maintenance surveys were conducted at approximately 1-3 month intervals to retrieve and replace deployed instruments. Small data gaps of a few hours duration occurred during maintenance surveys. Longer data gaps occurred for individual instruments due to battery failure or other equipment malfunction, and occasionally for part or all of the array during major storm events.
Positional_Accuracy:
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Due to the design of the buoy at the mooring, the closest position to the water surface for a deployed instrument is at 4.33 m depth. The "surface" CTD is below the buoy at 4.33 m.

Process_Description:
ADCP: Collection of time-series current velocity data began on 20041123 at latitude 30 05.410'N longitude 88 12.694'W. Data were collected with an RDI Workhorse Sentinel ADCP (http://www.rdinstruments.com/sen.aspx). Data are in 20 minute increments, with each value representing an average of continuous measurements over 5 minutes at a sampling frequency of 1 Hz. Raw data were accessed through WinADCP software and converted to text for custom processing using FORTRAN to create several types of diagnostic figures.

Process_Step:
Process_Description:
CTDs, thermisters, YSI: Raw data were converted to space-delimited text using SeaBird SeaTerm or SBE Data Processing software for the CTDs and thermisters, and EcoWatch for the YSI. Data were then processed using either FORTRAN or Matlab to create simple diagnostic figures and to align the measurement times among all instruments. Data from the YSI were collected at 20 minute increments, with each value representing an average of continuous measurements over 5 minutes. For most of the time series, CTD and thermister data were collected at 1-minute intervals; these were averaged into 20-minute bins to match the time interval of the YSI and ADCP.

ECMP
Attribute_Definition:
A series of error flags represented by four dots or asterisks. E stands for error velocity, which is calculated by the ADCP for each transducer, then provided as a standard deviation, according to user-defined parameters prior to deployment (bin size, blanking distance, etc.). Low error velocity is good. Flag threshold is 3.7 cm/s, or five times a standard deviation of 0.74 cm/s. | C stands for correlation magnitude data, which give the magnitude of the normalized echo autocorrelation at the lag used for estimating the Doppler phase change. A high correlation is good. Flag threshold is 64 (on a linear scale of 0 to 255). | M stands for magnitude of echo intensity. A strong return reflection of the outgoing signal is good. Weak echo intensity might be noise. Flag threshold is 40 decibels. | P stands for percent good, or PG. Four types of PG were provided by the ADCP. PG4 is percentage of velocity data that were calculated using all four beams; backscatter echo strength was strong from all beams. PG1 is percentage of velocity data that were calculated using three beams; although one beam did not provide useable data, correlation for the other three beams were still high. A high value for PG1 + PG4 is good. Flag threshold is 80.

Overview_Description:
Entity_and_Attribute_Overview:
Data tables containing hydrographic and current data from 20041021 to 20060928, at a permanent mooring 25 km southwest of the entrance to Mobile Bay, AL. Data are averaged at 20-minute intervals. Files are space-delimited ASCII text.
Entity_and_Attribute_Detail_Citation:
The full time-series of hydrographic and current data is from October 2004 to the present, though the portion funded by Compass Port, LLC is from 2004 to September 2006. Files containing the data are in 1-3 month subsets, with beginning and ending times based on when mooring maintenance occurred. A separate space-delimited text file exists for each deployed instrument, and a typical subset includes one file for the ADCP, one file for the surface CTD, one file for the bottom CTD, one file for each thermister (between 5 and 10), one file for a YSI if there was one, and one file containing temperature data from all instruments. Additionally, there is a file for a CTD vertical profile done at the time of maintenance.
