Assessment and Characterisation of Ireland's Green Tides (Ulva Species). [PDF]

PLoS One, 2017
Enrichment of nutrients and metals in seawater associated with anthropogenic activities can threaten aquatic ecosystems. Consequently, nutrient and metal concentrations are parameters used to define water quality. The European Union's Water Framework Directive (WFD) goes further than a contaminant-based approach and utilises indices to assess the ...

The ever-lasting green tides: What can we do？. [PDF]

Heliyon
Macroalgal blooms (Green tides) are occurring more frequently in many regions of the world because of the combined effects of increasingly intense human activity and climate change. In the last decade, the world's largest Ulva prolifera green tide has become a recurrent phenomenon, appearing every summer in the southern Yellow Sea, China.

Green and golden seaweed tides on the rise [PDF]

Nature, 2013
Sudden beaching of huge seaweed masses smother the coastline and form rotting piles on the shore. The number of reports of these events in previously unaffected areas has increased worldwide in recent years. These 'seaweed tides' can harm tourism-based economies, smother aquaculture operations or disrupt traditional artisanal fisheries.

Impacts of green tides on estuarine fish assemblages [PDF]

Estuarine, Coastal and Shelf Science, 2018
Abstract All around the world, an increasing proportion of estuarine systems are facing massive proliferations of green macroalgae, called green tides, in response to nutrient enrichment. The consequences of this perturbation for ichthyofauna that use estuarine systems as essential fish habitats remain understudied. To estimate these consequences, we

Green tides select for fast expanding Ulva strains

Science of The Total Environment, 2020
Green tides, the phenomenon whereby large volume of marine environment is taken over by the sea lettuce Ulva spp, are a seasonal occurrence thought to be caused mainly by anthropogenic eutrophication. The aggravation of green tide occurrence since the 1970s could however be due to the amplification of fast-growing strains within these areas.

A new assessment of the algal biomass of green tide in the Yellow Sea

Marine Pollution Bulletin, 2022
The annually recurring Yellow Sea green tide causes significant economic, social, and ecological impacts in China. Currently, the magnitude of Yellow Sea green tide is usually evaluated according to the snap shot maximum algal coverage area or artificially removed algal biomass.

The “green tides” influence on the heavy metal pollution of the coastal zone

Доклады Академии наук, 2019
We confirmed the hypothesis that algal mats provoke additional accumulation of heavy metals in the bottom sediments and release of labile metals. This process, in turn, enforce a pollution of the coastal zone. Our results give a new direction to the studies of the green tides worldwide problem.

Environmental Chemistry and Chemical Ecology of “Green Tide” Seaweed Blooms [PDF]

Integrative and Comparative Biology, 2015
Green tides are large growths or accumulations of green seaweeds that have been increasing in magnitude and frequency around the world. Because green tides consist of vast biomasses of algae in a limited area and are often seasonal or episodic, they go through periods of rapid growth in which they take up large amounts of nutrients and dissolved gases ...

Spatial and temporal variability of biomass and composition of green tides in Ireland

Harmful Algae, 2019
Although nutrient enrichment of estuarine and coastal waters is considered a key factor for the development of green tides, the extent, distribution, and species composition of blooms vary among systems of similar nutrient loading, which compromises our ability to predict these events based on information about nutrient status alone. Additional factors
