“…The higher turbidity, lower COD Mn , and TP contents shaped the physicochemical habitat of the Wangyu River in ratios similar to those of the Yangtze River. In the Yangtze River, the Bacillariophyta dominated the phytoplankton community in winter [29][30][31], which is consistent with the phytoplankton communities in the Wangyu River during the water diversion periods in this study ( Figure 5). However, these three physicochemical parameters only contributed a small proportion of phytoplankton community variations, most of which might be related to the inputs of the phytoplankton species from the Wangyu River and tributaries along with the Wangyu River.…”

“…During the non-diversion period of 2016, Cyanophyta dominated at the sites in the middle and lower reaches of the Wangyu River. Since Bacillariophyta is the dominant phytoplankton phyla in the Yangtze River especially in winter [29][30][31], the dominance of Bacillariophyta in the Wangyu River might be mainly ascribed to the allochthonous species input. In this study, the Cyclotella sp.…”

Abstract:To reveal the effects of water diversion from the Yangtze River to Lake Taihu on the phytoplankton habitat of the main water transfer channel of the Wangyu River, we investigated the water's physicochemical parameters and phytoplankton communities during the water diversion and non-diversion periods over the winters between 2014-2016, respectively. During the water diversion periods in the winter of 2014 and 2015, the nutrients and organic pollutant contents of the Wangyu River channel were significantly lower than those during the non-diversion period in 2016. Moreover, the phytoplankton diversities and relative proportions of Bacillariophyta during the diversion periods evidently increased during the water diversion periods in winter. The increase in the water turbidity content, the decrease in the contents of the permanganate index, and the total phosphorus explained only 21.4% of the variations in the phytoplankton communities between the diversion and non-diversion periods in winter, which revealed significant contributions of the allochthonous species from the Yangtze River and tributaries of the Wangyu River to phytoplankton communities in the Wangyu River. The increasing gradient in the contents of nutrients and organic pollutants from the Yangtze River to Lake Taihu indicated the potential allochthonous pollutant inputs along with the Wangyu River. Further controlling the pollutants from the tributaries of the Wangyu River is critical in order to improve the phytoplankton habitats in river channels and Lake Taihu.

Abstract. The distribution of the phytoplankton size class (PSC) and the variations in the size classes are key to understanding 10 ocean biogeochemical processes and ecosystem. Remote sensing of the PSC in the East China Sea (ECS) remains a challenge, although many PSC algorithms have been developed. Here based on a local dataset from the ECS, a regional model was tuned to infer the PSC from the spectral features of normalized phytoplankton absorption (aph) using a principal component analysis approach. Before applying the refined model to the real MODIS (Moderate Resolution Imaging Spectroradiometer) data, reconstructing satellite Rrs at 412 and 443 nm becomes critical through modeling them from Rrs between 469 and 555 nm using 15 multiple regression analyses. Satellite-derived PSC values compare well with those derived from pigment composition, which demonstrates the potential of satellite ocean color data to estimate PSC distributions in the ECS from space. The refined model was applied to aph derived from Rrs observations collected by MODIS over the ECS from 2003 to 2016. Seasonal images show that the PSC distribution was heterogeneous in both temporal and spatial scales. Seasonal variations of the PSC in the ECS were probably affected by a combination of the water column stability, upwelling, sea surface temperature, and the Kuroshio 20Current. Additionally, human activity and riverine discharge may also influence the PSC distributions in the ECS, especially in coastal regions.Biogeosciences Discuss., https://doi
