TLDR
Understanding is increased about how the green tide declined gradually in the North Yellow Sea, and chlorophyll contents and fluorescence activity of free-floating thalli in theNorth Yellow Sea were both significantly lower than that in the South Yellow Sea.About:

Spatial and temporal nutrient variations in the Yellow Sea and their effects on Ulva prolifera blooms
TL;DR: In this paper, the spatial and temporal distributions of dissolved inorganic nutrients (DIN, PO 4 -P and SiO 3 -Si) and dissolved organic nutrients (DON and DOP) were analyzed through field surveys in the southern Yellow Sea (SYS), particularly in the Subei coastal area, during green tide occurrences.

The origin of the Ulva macroalgal blooms in the Yellow Sea in 2013
Jianheng Zhang,Yuanzi Huo,Hailong Wu,Kefeng Yu,Jang K. Kim,Charles Yarish,Yutao Qin,Caicai Liu,Ren Xu,Peimin He +9 more
TL;DR: It is concluded that the significant biomass of Ulva species on the Pyropia rafts during the harvesting season in radial tidal sand ridges played an important role in the rapid development of blooms in the Yellow Sea.

Changes in morphological plasticity of Ulva prolifera under different environmental conditions: A laboratory experiment.
TL;DR: The results demonstrate conclusively that U. prolifera can acclimatize in the laboratory to the changes of environmental factors (salinity and temperature) by morphology-driven physiological and biochemical variation and suggest that the morphological plasticity of U. proliferation may be an important factor for it to outcompete other algal species in a changing ocean.

Microplastics in bloom-forming macroalgae: Distribution, characteristics and impacts.

TL;DR: The trapping of MPs by drifting Ulva prolifera in the Yellow Sea during the green-tide period showed a high tolerance to MPs, indicating that the plastics trap in drifting macroalgae can alter the spatio-temporal distribution of MPs in the oceans.
Journal ArticleDOI
Annual patterns of macroalgal blooms in the Yellow Sea during 2007-2017.
TL;DR: It is suggested comprehensive utilization of the macroalgal blooms is a feasible way to control them after analysis of annual variations of Pyropia aquaculture area in the Southern Yellow Sea revealed that a great expansion in “Sansha” regions was mainly responsible for the initial blooms in 2007.

Copper enzymes in isolated chloroplasts. polyphenoloxidase in beta vulgaris
TL;DR: Evidence that a copper enzyme, polyphenoloxidase (otherwise known as tyrosinase or catecholase), is localized in the chloroplasts of spinach beet (chard), Beta vu?garis is presented.

Chlorophyll fluorescence—a practical guide
Kate Maxwell,Giles N. Johnson +1 more
TL;DR: An introduction for the novice into the methodology and applications of chlorophyll fluorescence is provided and a selection of examples are used to illustrate the types of information that fluorescence can provide.
Supporting Online Material for Spreading Dead Zones and Consequences for Marine Ecosystems
Robert J. Diaz,Rutger Rosenberg +1 more
TL;DR: The formation of dead zones has been exacerbated by the increase in primary production and consequent worldwide coastal eutrophication fueled by riverine runoff of fertilizers and the burning of fossil fuels as discussed by the authors.

Spreading Dead Zones and Consequences for Marine Ecosystems
Robert J. Diaz,Rutger Rosenberg +1 more
TL;DR: Dead zones in the coastal oceans have spread exponentially since the 1960s and have serious consequences for ecosystem functioning, exacerbated by the increase in primary production and consequent worldwide coastal eutrophication fueled by riverine runoff of fertilizers and the burning of fossil fuels.

World-Wide Delivery of River Sediment to the Oceans
John D. Milliman,Robert H. Meade +1 more
TL;DR: The authors showed that rivers with large sediment loads (annual discharges greater than about $15 \times 10^{6}$ tons) contribute about $7 −times 10 −9$ tons of suspended sediment to the ocean yearly.
