Abstract Zooplankton transfer substantial energy in aquatic food webs and are used as indicators of environmental change. Syntheses of zooplankton community dynamics globally require datasets that span a wide range of environmental gradients; however, these datasets are limited due to methodological differences across programs, taxonomic ...

Eutrophication and proliferation of nuisance and harmful algal blooms are a major cause of water-quality impairment globally. Here, we analyze the world’s longest continuous (150-year) river water-quality dataset for the River Thames, U.K.

Abstract The demand for efficient image sorting methods has increased due to technological advancements that enable more intensive phytoplankton monitoring. Both statistical and machine learning algorithms can misidentify algal taxa in taxonomically diverse samples, in which phytoplankton morphology and image traits can vary.

Image processing for smart browsing of ocean colour data products and subsequent incorporation into a multi-modal sensing framework [PDF]
Ocean colour is defined as the water hue due to the presence of tiny plants containing the pigment chlorophyll, sediments and coloured dissolved organic material and so water colour can provide valuable information on coastal ecosystems.

Bloom-forming cyanobacteria and dinoflagellates in five Argentinian reservoirs: Multi-year sampling
Harmful algal blooms are important threats to reservoir condition. Over a 15-year period, we sampled five Argentinian reservoirs to identify the responsible species for harmful algal blooms and determine the water quality factors driving their occurrence.

Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...

Volatile Organic Compounds in Rainwater: A New Frontier in Atmosphere–Biosphere Interactions
Abstract Rainwater is a key vector of atmospheric deposition, linking the atmosphere with terrestrial and aquatic ecosystems. While the inorganic chemistry of precipitation (dominated by sulfate, nitrate, ammonium, and trace metals) has been extensively studied, organic compounds in rainwater have received less attention, and Volatile Organic Compounds

ABSTRACT Fisheries are facing increasingly frequent and severe climate change‐related stressors such as marine heatwaves, harmful algal blooms, and species distribution shifts. Many fisheries management bodies have been working to increase the capacity of their regulatory systems to adapt to these new conditions, but progress has been slow and ...
