Steps to Submit Ocean Acidification Data to NCEI
Prepare your metadataPlease download the Metadata submission form and fill out your metadata information into the spreadsheet (Column C). Here is a filled out submission form with example contents, in case you find it useful. The submission form can be applied to most types of ocean acidification data including chemical, experimental, and model output data.
- We encourage you to fill out as much information as possible, although only those marked with red are required. If a section does not apply to you, you can ignore the section entirely, even though some of its elements are marked red.
- Please avoid using special characters, e.g., μ, ±, ℃, etc. wherever possible.
- The main component of the template is the "variable metadata section" (check out Row #211-230 for an example). Here, a variable refers to a measured/derived property only. For example, temperature, oxygen, growth rate are variables, but date, longitude, latitude, bottle number, quality flags, standard deviations, etc. are not considered variables in this section of the template.
- For biological studies, the bounding box and geographic name fields are for the location where the organisms are collected.
- If you need help with a specific metadata element, please refer to the Instructions file. You can use the help reference numbers in Column D of the submission form as a key to find their definitions in the Instructions file.
Alternatively, you could fill out the XML template file (not recommended). Once downloaded, please change the file extension from ".txt" to ".xml". We recommend to use notepad++, or an xml editor to fill out your information. Please do not use rich format editor, such as Microsoft Word.
Tips: Want to start with someone else's metadata? No problem. First, click here to see a list of data packages that have already been published at OADS. Once you are at the main page of a specific data set, click the "Download data" button to download the metadata file (Excel spreadsheet) to your computer and start preparing your metadata from there. If you want to get the XML file instead. Right click anywhere on the page, and choose "View Page source".
Prepare your data files
No specific file format is required. We recommend using ASCII character encoding (e.g., comma-separated values (CSV), Excel, etc.) or NetCDF file format. Please avoid the use of commercial proprietary data file formats.For in situ observational water chemistry data, please follow the below data templates (feel free to add or remove variables as needed) as much as you can:
- Underway data: Column header names description (data file (csv) example)
- Profile data (e.g., CTD, discrete bottle water samples, etc): Column header names description (data file (csv) example)
- Mooring data (e.g., buoys): Column header names description (data file (csv) example)
When ready, send your metadata and data files to NCEI
If your data files are small (less than 20MB), please feel free to send them to us in an email. You shall send your e-mail message to nodc.dataofficer (a) noaa.gov, and cc noaa.ocads (a) noaa.gov. Please indicate that this is an Ocean Acidification data set in the email. If you are submitting multiple data sets, please send out one email for each submission, and be sure to use different email subject lines.
If your data files are too big to be sent as email attachments, we recommend you to send your data via File Transfer Protocol (FTP). We have set up a dedicated ftp address for submission of NOAA OAP data to NCEI at ftp://ftp.nodc.noaa.gov/pub/incoming/oads/. See sample FTP data submission. When done, please send an e-mail message to nodc.dataofficer (a) noaa.gov, and cc noaa.ocads (a) noaa.gov to let us know that an ocean acidification data set was submitted for archival at NCEI.
