NewsBloomNet turns lake data into early algal bloom warnings
A research team has developed BloomNet, an interpretable deep-learning framework that forecasts harmful algal blooms at hourly resolution up to 72 hours ahead while also showing how risk changes over time.

NewsSouth Australian algal bloom species the world’s most toxic harmful microalga yet recorded
The marine microalgae responsible for the most devastating effects of the South Australian harmful algal bloom (HAB) has now been shown to be the most toxic species of its kind ever studied.

NewsStudy provides detailed assessment of shifts in toxin producing phytoplankton abundance
Researchers in the UK have shown how the distributions of two phytoplankton groups – known to produce natural toxins that can halt shellfish harvesting – have changed in the North East Atlantic over the last six decades.

NewsAlgal bloom crisis shows climate risks need evaluative governance
Identifying and analysing climate risks is a necessary function of governments, but researchers argue such processes will not lead to effective action without taking additional steps to understand which risks are considered unacceptable by the community and prioritising responses accordingly.

NewsFrom sediment to surface: How invisible plumes trigger harmful algal blooms
A new study shows that algal blooms can begin days earlier than previously recognized, originating from chlorophyll-rich plumes rising from lake sediments before any surface discoloration appears.
-
NewsCAROSEL offers new ‘spin’ on monitoring water quality in real time - and tracking harmful algal blooms
Researchers can continuously track the exchanges of different forms of nitrogen between bottom sediments and the overlying water. Their novel approach enables measuring how much ammonium (NH₄⁺) is released from sediments in real time, multiple times a day, over an extended period.

NewsNew study finds concerning sea star response to an algal neurotoxin
Researchers found potentially concerning concentrations of the neurotoxin domoic acid in sea stars even in the absence of the algal blooms that are thought to drive DA outbreaks.
-
NewsHarmful algae blooms have secret to success over other algaes
An alga that threatens freshwater ecosystems and is toxic to vertebrates has a sneaky way of ensuring its success: It suppresses the growth of algal competitors by releasing chemicals that deprive them of a vital vitamin.

NewsIlluminated sugars show how microbes eat the ocean’s carbon
A team of scientists have designed a molecular probe that lights up when a sugar is consumed. They described how the probe helps to study the microscopic tug-of-war between algae and microbial degraders in the ocean.

NewsFecal samples from bowhead whales link ocean warming to rising algal toxins in Arctic waters
Rising toxins found in bowhead whales, harvested for subsistence purposes by Alaska Native communities, reveal that ocean warming is causing higher concentrations of algal toxins in Arctic food webs.
-
NewsLiving near harmful algal blooms reduces life expectancy with ALS
Living close to cyanobacterial harmful algal blooms — which are present US-wide but are more common in coastal and Great Lake states — heightens the rate of dying from amyotrophic lateral sclerosis, or ALS, a study suggests.
-
NewsAffordable real-time sensor system for algal bloom detection
Engineers have developed a real-time, low-cost algal bloom monitoring system utilizing inexpensive optical sensors and a novel labeling logic. The system achieves higher accuracy than state-of-the-art AI models such as Gradient Boosting and Random Forest.
-
NewsWater researchers develop prediction system for harmful algae
Researchers are collaborating on a next-day prediction model to warn and inform water managers about harmful algal blooms. Using water samples and computer algorithms, the team developed prediction models based on two water sources feeding the Caloosahatchee River.
-
NewsStudy uncovers how the plastisphere can influence growth of harmful algal blooms
A new study published in Sustainable Microbiology delves into how the age and size of microplastics affects the growth of harmful algal blooms.
-
NewsBacterial villain behind Lake Erie’s ‘potent toxin’ unveiled by study
In Lake Erie, cyanobacteria can proliferate out of control, creating algal blooms that produce toxins that can harm wildlife and human health. Researchers have IDed the organism responsible for the toxins: a cyanobacteria called Dolichospermum.
