contribution of atmospheric transport to phosphorus in the East China Sea in summer

For the analysis of the main sources of phosphate in the East China Sea during summer, we choose the area between 120.93 ˚ E-125.9 ˚ E and 26.08˚ N-32.35 ˚ N as research sites . The samples were all from the voyage of the research ship (Xiangyanghong 18). Surface seawater was collected at 49 stations for δ18Op analysis by a conductivity-temperature-depth profiler. Then we utilized δ18Op to trace the source of phosphate in the East China Sea.  The δ18Op values in seawater are affected by water masses with different phosphate concentrations.We need the two-component mixing model for the analysis of water masses that control phosphate.In this research, atmospheric deposition and adjacent sea transportation were used as terrestrial and seawater end-members respectively to construct the δ18Op end-member mixing model. In order to quantify the source of phosphate in the sea, a Bayesian isotope mixing model run in the R software package (Stable Isotope Analysis in R, SIAR) was selected for analysis.

High resolution opacities for H2/He atmospheres

This set of molecular and atomic opacities has been built based on the same opacity sources used for calculating the correlated-k coefficients in the following repositories: 10.5281/zenodo.5590997 (11 windows) 10.5281/zenodo.5590995 (30 windows) 10.5281/zenodo.5590986 (180 windows) 10.5281/zenodo.5590989 (196 windows) These opacities can be used to generate high resolution spectra for the atmospheric structures computed with the correlated-k coefficients above. The set includes C2H2, C2H4, C2H6, CH4, CO, CO2, CrH, Fe, FeH, H2, H3+, H2O, H2S, HCN, LiCl, LiF, LiH, MgH, N2, NH3, OCS, PH3, SiO, TiO, and VO, in addition to alkali metals (Li, Na, K, Rb, Cs). The opacities are calculated for a grid of 1460 pressure-temperature points, from10^−6 to 3000 bar and from 75 to 4000 K, listed in the file 1460_layer_list. Each *.zip file contains one opacity file for each pressure-temperature layer, with the species’ name, the pressure, and the temperature given in the filename. The opacity is given in units of cm^2/molecule. For completeness, each *.zip file also contains a file named wavelengths.txt, listing the wavelengths corresponding to each opacity point, in units of microns. All the opacities are calculated on the same wavelength grid.  The references for the line lists used in these opacity calculations can be found in the file Opacity_references_2021.pdf. Please include these references, as well as the reference to this Zenodo repository when publishing your paper.  Resources supporting this work were provided by the NASA High-End Computing (HEC) Program through the NASA Advanced Supercomputing (NAS) Division at Ames Research Center.

Carbon absorption capacity determines the response of algal competitiveness to elevated atmospheric CO2

Although many studies have focused on the effects of elevated atmospheric CO2 on algal growth, few studies have demonstrated how CO2 interacts with carbon absorption capacity to determine the algal competition at the population level. We conducted a pairwise competition experiment of Phormidium sp., Scenedesmus quadricauda, Chlorella vulgaris, and Synedra ulna. The results showed that when the CO2 concentration increases from 400 to 760 ppm, the competitiveness of S. quadricauda increased, the competitiveness of Phormidium sp. and C. vulgaris decreased, and the competitiveness of S. ulna was always the lowest. we constructed a model to explore whether interspecific differences in affinity and flux rate for CO2 and HCO3− could explain changes of competitiveness between algae species along the gradient of atmospheric CO2 concentration. Affinity and flux rate are the capture capacity and transport capacity of substrate, respectively, which are inversely proportional to each other. Low resource concentration is beneficial to the growth and reproduction of algae with high affinity. The simulation results showed that when the atmospheric CO2 concentration was low, species with high affinity for both CO2 and HCO3− (HCHH) had the highest competitiveness, followed by the species with high affinity for CO2 and low affinity for HCO3− (HCLH), the species with low affinity for CO2 and high affinity for HCO3− (LCHH) and the species with low affinity for both CO2 and HCO3− (LCLH); when the CO2 concentration was high, the species were ranked according to the competitive ability: LCHH > LCLH > HCHH > HCLH. Thus, with the increase of atmospheric CO2 concentration, the competitive advantage changed from HCHH species to LCHH species. These results indicate the important species types contributing to water bloom under the background of increasing global atmospheric CO2, highlighting the importance of carbon absorption characteristics in understanding, predicting and regulating population dynamics and community composition of algae.
