The original data and metadata files were sent to CDIAC as ZIP file by the 
GLODAPv2 group in July 2016 . The data set was archived at CDIAC in 2016.
The data set was transferred to NCEI on May 11, 2017 for archive. All original 
data and metadata files were transferred to the directory of data/0-data/. NCEI 
personnel extracted the longitude and latitude data, and plotted a sampling station 
map. The GLODAPv2 map and the generated longitude latitude file were saved in the 
about/ directory. NCEI personnel also created the .xls metadata file and converted 
to .csv format and saved it in the data/1-data/ directory.
