Data Management Plan
DMP Template v2.0.1 (2015-01-01)Please provide the following information, and submit to the NOAA DM Plan Repository.
Reference to Master DM Plan (if applicable)
As stated in Section IV, Requirement 1.3, DM Plans may be hierarchical. If this DM Plan inherits provisions from a higher-level DM Plan already submitted to the Repository, then this more-specific Plan only needs to provide information that differs from what was provided in the Master DM Plan.

5. Data Lineage and Quality
NOAA has issued Information Quality Guidelines for ensuring and maximizing the quality, objectivity, utility, and integrity of information which it disseminates.
(describe or provide URL of description):
- Water samples were collected at each location and depth with Niskin bottles and stored as described by Dickson et al. (2009) except they were not poisoned with mercuric chloride. Water was filtered through 53 m nylon sleeves placed around the exit hose on the Niskin bottle as it was collected from bottom to top with 0.5 to 1 volume overflow in pre-cleaned BOD (biological oxygen demand) bottles (after rinsing). The glass-stoppered BOD bottles were sealed with Apiezon L grease, refrigerated, and analyzed within 2 w of collection. Observation parameters did not change measurably within the 2 week measurement period. Additional water was collected unfiltered for chlorophyll measurement in brown Nalgene bottles (250 ml). Chlorophyll samples were refrigerated, filtered within 24 h of collection (0.7 m glass microfiber Whatman GF/F), placed in cryovials and stored at -80C pending analysis.
- Water samples were analyzed for pH, total alkalinity (TA), total dissolved inorganic carbon (TC) and salinity with the methods of Dickson et al. (2009). Quality assurance measures were included daily with every group of samples. These measures included sample replicates for precision and for accuracy, certified reference material (CRM) for TA, TC, and salinity (Oceanic CO2 Quality Control - Marine Physical Laboratory, Scripps Institution of Oceanography, CA).
- pH was measured in 10 cm cells with the indicator dye m-cresol purple in a UV/visible spectrophotometer (Model 8453, Agilent Technologies). A tris buffer solution in synthetic seawater served as the CRM (Oceanic CO2 Quality Control - Marine Physical Laboratory, Scripps Institution of Oceanography, CA). Typical precision, measured as the coefficient of variation, was 0.08%. Typical accuracy was 0.06%.
- Total alkalinity was initially measured by the open cell titration method with a Dosimat autopipette (Metrohm) through August 2011 and thereafter with a QC Titration Module a TitraSip System (Mantech Associates Inc.). A series of pH buffer solutions was used to calibrate the Ross pH probe (Thermo Scientific) and the probe was subsequently soaked in filtered seawater for 1 h before sample measurement. A 0.7 M NaCl solution was used as a rinse between seawater sample measurements. Conditioning soaks were not used with the manual TA analysis approach. Typical precision was 3.6% with the Dosimat and 0.5% with the Mantech. Typical accuracy was 1.3% with the Dosimat and 0.7% with the Mantech.
- Total dissolved inorganic carbon was measured with a CO2 Coulometer (CM5014, UIC Inc.) and Acidification Module (CM5130, UIC Inc.; Dickson et al. 2009). Each 20 g water sample was acidified with 6 ml of 1.5 M phosphoric acid to release the inorganic carbon as CO2 gas. An electrochemical cell with cathode/anode solutions and potassium iodide salt was used to measure the amount of CO2 (g C). Potassium hydroxide (45%) was used as a pre-scrubber and acidified potassium iodide (50% to pH 3) as a post-scrubber on the acidification module. High and low concentrations of sodium carbonate were used to calibrate the Coulometer, and a slope calibration factor was applied to each inorganic carbon value (Goyet and Hacker 1992). Typical precision and accuracy were 0.9 and 0.5%, respectively.
- Chlorophyll a was measured as described by (Parsons, Maita et al. 1984) in a fluorometer (TD 700, Turner Designs). Each sample was measured twice and results averaged. Salinity was measured with an AutoSal (Model 8400B, Guildline Instruments Limited). Each sample was measured in triplicate and results averaged. Typical precision and accuracy were 0.7 and 7%, respectively.
- Calcite and aragonite saturation levels were calculated from pH and TC measurements with the CO2sys (Lewis and Wallace). Alternative calculations as a function of TA and TC were also completed.

6. Data Documentation
The EDMC Data Documentation Procedural Directive requires that NOAA data be well documented, specifies the use of ISO 19115 and related standards for documentation of new data, and provides links to resources and tools for metadata creation and validation.

7. Data Access
NAO 212-15 states that access to environmental data may only be restricted when distribution is explicitly limited by law, regulation, policy (such as those applicable to personally identifiable information or protected critical infrastructure information or proprietary trade information) or by security requirements. The EDMC Data Access Procedural Directive contains specific guidance, recommends the use of open-standard, interoperable, non-proprietary web services, provides information about resources and tools to enable data access, and includes a Waiver to be submitted to justify any approach other than full, unrestricted public access.
There are no legal restrictions on access to the data. They reside in public domain and can be freely distributed.
Notes: The name of the Organization of the most recent Support Role of type "Distributor" is used. The support role must be in effect. This information is not required if an approved access waiver exists for this data.
Notes: This field is required if a Distributor has not been specified.

8. Data Preservation and Protection
The NOAA Procedure for Scientific Records Appraisal and Archive Approval describes how to identify, appraise and decide what scientific records are to be preserved in a NOAA archive.

Notes: This field is required if archive location is World Data Center or Other.
Notes: This field is required if archive location is To Be Determined, Unable to Archive, or No Archiving Intended.
Notes: Physical Location Organization, City and State are required, or a Location Description is required.
Discuss data back-up, disaster recovery/contingency planning, and off-site data storage relevant to the data collection
IT Security and Contingency Plan for the system establishes procedures and applies to the functions, operations, and resources necessary to recover and restore data as hosted in the Western Regional Support Center in Seattle, Washington, following a disruption.
