| Research Abstract |
We create a dataset which is the basic dataset to draw more accurate spatial distribution of nutrients in global ocean. During the study period we conducted 6 cruises in which reference material of nutrients in seawater was used, precision of nutrients analyses is better than 0.2 % and station-station comparability was ensured. We also collected all of the cruises in which nutrients data were available. We did crossover analyses at 243 crossovers where our cruises were reference to decide factors to adjust nutrients concentration obtained in other cruises. In addition we included dissolved oxygen as an additional parameter of the dataset. Finally, we got the dataset of 0.5 deg. by 0.5 deg. mesh, 136 layers up to 6500 meters depth for nitrate, phosphate, silicate and dissolved oxygen, respectively.
