Data on dissolved organic matter, sea ice and environment in surface water of Antarctic Ocean
On behalf of my coauthors, I am pleased to submit a manuscript entitled “Sea ice melting is a factor driving dissolved organic matter change in surface waters of Antarctic Ocean close to the Prydz Bay”. The South Ocean (or Antarctic Ocean) is the largest sink for atmospheric CO2, and is sensitive to...
