“…Since high BPA removal efficiency (N94%) was achieved at environmental relevant concentrations, U. prolifera might have the potential of efficiently removing BPA from coastal water within its floating area during the outbreak of green tide. Due to the high biomass (8.47 g m −2 ) and huge covered area (3.6 × 10 4 km 2 ) of the U. prolifera during the outbreak of green tide (Liu et al, 2015), the contribution of the green-tidal algae in the removal of BPA in the coastal and marine waters should be considerable.…”

“…China experienced green tides in the Yellow Sea consecutively from 2007 to 2018. In every wet season of these years, the free-floating algal patches of green tides started from the coastal area of Jiangsu Province, then moved northward progressively under wind-current action, and finally destined to the southern coastal zone of Shandong Peninsula with masses of algae being washed ashore, accompanying with various adverse impacts on indigenous biodiversity, aquaculture and tourism (Liu et al, 2015;Luo et al, 2012;Van Alstyne et al, 2015). Ulva prolifera (U. prolifera) is considered as the dominant species in green tides (Zhao et al, 2015).…”

New phycoremediation of coastal water with BPA occurred during green tide bloom. • N94% of BPA was removed by the greentidal algae U. prolifera. • BPA removal efficiency has positive relationship with light, nutrient and temperature. • High removal efficiency (N94%) was achieved at environmental relevant concentrations. • BPA concentration in green tide bloom area was much lower than that in adjacent area.

“…Despite the reported positive interactions between Ulva and the various species of bivalves in prior studies (Carroll et al, 2010;Heck et al, 2003;Sogard and Able, 1991;Wilson et al, 1990; this study), macroalgae can negatively impact bivalves and other calcifying organisms. Secondary metabolites released by Ulva can elevate mortality rates in the larval stages of bivalves (Diederich, 2005;Nelson et al, 2003), barnacles (Brock et al, 2007;Magre, 1974), crabs (Johnson and Welsh, 1985), and molluscs (Wang et al, 2011). Ulva can form "green tides" (Smetacek and Zingone, 2013) that, upon their collapse, can create hypoxic regions (Valiela et al, 1992) that can negatively affect benthic fauna (Viaroli et al, 2001).…”

Abstract. Coastal ecosystems can experience acidification via upwelling, eutrophication, riverine discharge, and climate change. While the resulting increases in pCO2 can have deleterious effects on calcifying animals, this change in carbonate chemistry may benefit some marine autotrophs. Here, we report on experiments performed with North Atlantic populations of hard clams (Mercenaria mercenaria), eastern oysters (Crassostrea virginica), bay scallops (Argopecten irradians), and blue mussels (Mytilus edulis) grown with and without North Atlantic populations of the green macroalgae, Ulva. In six of seven experiments, exposure to elevated pCO2 levels (∼1700 µatm) resulted in depressed shell- and/or tissue-based growth rates of bivalves compared to control conditions, whereas rates were significantly higher in the presence of Ulva in all experiments. In many cases, the co-exposure to elevated pCO2 levels and Ulva had an antagonistic effect on bivalve growth rates whereby the presence of Ulva under elevated pCO2 levels significantly improved their performance compared to the acidification-only treatment. Saturation states for calcium carbonate (Ω) were significantly higher in the presence of Ulva under both ambient and elevated CO2 delivery rates, and growth rates of bivalves were significantly correlated with Ω in six of seven experiments. Collectively, the results suggest that photosynthesis and/or nitrate assimilation by Ulva increased alkalinity, fostering a carbonate chemistry regime more suitable for optimal growth of calcifying bivalves. This suggests that large natural and/or aquacultured collections of macroalgae in acidified environments could serve as a refuge for calcifying animals that may otherwise be negatively impacted by elevated pCO2 levels and depressed Ω.

“…Introduction Ulva prolifera (U. prolifera) has been frequently involved in terrible green tides in the coastal areas. From 2007 onwards, green tides dominated by U. prolifera frequently flourish along the coastal regions of Jiangsu Province (China) (Liu et al, 2015), and then float northward with a fresh biomass of 100 million metric tons until land on seashore of Shandong Province, influencing the coastal ecosystems of north China. Additionally, N1000 transportation vehicles and 1600 fishing vessels were dispatched to clean up the massive bloom, causing an economic loss exceeding US $100 million in 2008 (Zhang et al, 2013b).…”

Editor: Filip M.G. Tack Rare information is available on the adsorptive removal of polycyclic aromatic hydrocarbons (PAHs) in the presence of algal detritus deposited in the coastal sediment during the outbreak of the green tide. The adsorptive removal of typical PAHs by Ulva prolifera (U. prolifera) detritus was firstly investigated since the algal detritus was of great importance for the biogeochemical cycle of coastal contaminants. The results showed that equilibrium adsorptive capacities of naphthalene, phenanthrene and benzo[a] pyrene on the U. prolifera detritus were 1.27, 1.97, and 2.49 mg kg −1 , respectively, at the initial concentration of 10 μg L −1 . The in situ monitoring using laser confocal scanning microscopy confirmed the adsorptive removal of PAHs by U. prolifera detritus. The adsorption of these PAHs was highly pH-dependent. The increase in salinity led to the increase in naphthalene removal rate, while the salinity showed scarce influence on the removal of phenanthrene and benzo[a] pyrene. There was a good linear relationship (R 2 ≥ 0.9892) between the removal efficiency of PAHs and the initial concentration of PAHs. Slow desorption kinetics and low desorption rate (b16%) indicated that the adsorptive removal of PAHs could be benign to the environment. These findings demonstrated that the occurrence of green tide could provide a new natural remediation approach for contamination of PAHs through the adsorptive removal by the detritus of green tidal algae deposited in the coastal sediment.
