Improved seasonal prediction of harmful algal blooms in Lake Erie using large-scale climate indices

Communications Earth & Environment, 2022
A machine learning approach based on nutrient loading observations and physical large scale climate indices improves early seasonal prediction of harmful algal bloom activity between July and October in Lake Erie, which can help local fisheries ...

Finding Plankton: A Marine Science Scavenger Hunt for Local Communities

Limnology and Oceanography Bulletin, EarlyView.
Abstract At a time of increasing political polarization and rapidly accelerating climate change, it is important to build public knowledge and empathy toward nature to foster behavioral changes; however, addressing a knowledge deficit can be insufficient to affect these changes.

Assessment of GCOM-C Satellite Imagery in Bloom Detection: A Case Study in the East China Sea

Remote Sensing, 2023
The coast of the East China Sea (ECS) is one of the regions most frequently affected by harmful algal blooms in China. Remote sensing monitoring could assist in understanding the mechanism of blooms and their associated environmental changes.

Statistical filtering to aid in the sorting of phytoplankton: The effects of image library size and phytoplankton shape

Limnology and Oceanography: Methods, EarlyView.
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.

Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems

Limnology and Oceanography: Methods, EarlyView.
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 ...

Harmful algal blooms are preceded by a predictable and quantifiable shift in the oceanic microbiome

Nature Communications
Harmful algal blooms (HABs) have become a worldwide environmental and human health problem, stressing the urgent need for a reliable forecasting tool. Dynamic interactions between algae, including harmful algae, and bacteria play a large role regulating ...

Harmful Freshwater Algal Blooms, With an Emphasis on Cyanobacteria [PDF]

The Scientific World JOURNAL, 2001
Suspended algae, or phytoplankton, are the prime source of organic matter supporting food webs in freshwater ecosystems. Phytoplankton productivity is reliant on adequate nutrient supplies; however, increasing rates of nutrient supply, much of it manmade, fuels accelerating primary production or eutrophication.

Sustainable Metal Recovery From E‐Waste: Exploring Greener Leachates in Hydrometallurgical Processes

MetalMat, EarlyView.
Recycling of electronic waste to synthesize valuable metals using green leachate. ABSTRACT The accumulation of electronic waste (e‐waste) poses environmental hazards and leads to the loss of valuable metals such as gold, silver, copper, and rare earth elements.

Forecasting the impact of food‐provisioning and other stressors on a marine top‐predator population

Oikos, EarlyView.
Wildlife tourism can alter animal behavior, affect vital rates and diminish population viability but its impact in the context of other human‐ and environmental disturbances, remain largely unstudied. Using simulation models and leveraging a robust long‐term dataset spanning eight years, we evaluated the contribution of wildlife feeding, in the context
