Assessing the risk to aquaculture from Harmful Algal Blooms (HABs)
Harmful Algal Blooms (HABs) occur worldwide with regionally based differences in their<br/>occurrences. Some of these events have human health consequences due to associated<br/>shellfish poisoning symptoms after consumption of contaminated organisms. Negative<br/>economic implications from HABs …

From Lunar Modules to In-Situ Habs: Conceptualization & Considerations of a Developing Lunar South Pole Base
This project delves into the strategic considerations of how a Lunar base may expand over time and theorizes how in-situ resource utilization (ISRU) technologies could be used to construct more robust and protective habitation that integrates with existing prefabricated modules for supporting …

Drivers And Dynamics Of Harmful Algal Blooms: Understanding Nitrogen Fixation And Bloom Composition In Minnesota Temperate Lakes
… microbial communities, harmful algal blooms (HABs), dominated by cyanobacteria capable of producing toxins, have emerged as a growing environmental concern due to their impacts on water quality, ecosystem services, and human health. Historically, phosphorus has been considered the primary …

Environmental drivers and advective transport of harmful phytoplankton in North West European shelf seas
… formation and advection of harmful algae blooms (HABs). To minimise adverse effects of HABs it is necessary to improve our understanding of links between advection, environmental changes and HAB development. The aims of this PhD project were therefore to:<br/>1) Provide a better understanding of …

Effects Of Nutrient Overload And Environmental Conditions On Algal Bloom Formation: A Case Study Of Water Sources In Eastern Kentucky
… of these ponds observe harmful algal blooms (HABs) that release toxins into the water, potentially limiting the use of these ponds. A pilot study in summer 2018 observed a harmful algal bloom (HAB) occurring in one pond in Madison Country that roughly correlated with a rise in water sulfate …

Identifying and Characterizing Non-Coding RNAs in the Dinoflagellate <i>Karenia brevis</i>
… and are known as harmful algal blooms (HABs). A number of negative effects, including closing of recreational beaches and economic loss, are observed during HABs. Predictably, the longer a bloom persists, the greater its effects on human, environmental and economic health. Karenia …

Multi-sensor mooring development and its use to characterise physical processes relevant to harmful algal bloom dynamics in the St Helena Bay area, South Africa
Harmful algal blooms (HABs), typically attributed to dinoflagellate species, occur along the west coast of South Africa, particularly during the latter part of the upwelling season. As part of the Benguela Current Large Marine Ecosystem (BCLME) programme, a buoy has been developed locally for …

Modeling the Spread of Airborne Particles Associated with Harmful Algal Blooms and Plumes of Colored Smoke
… oceans are threatened by harmful algal blooms (HABs), caused mostly by toxic cyanobacteria. When people or animals drink the toxic water, it can be damaging to their health, potentially leading to hospitalization or even death. In some cases, these toxins are not just limited to the water, but …

Chitosan Graphene Composite Fabrication and Characterization for Treatment of Harmful Algal Blooms and Toxins
… a management strategy for harmful algal blooms (HABs) caused by various species of cyanobacteria. These chitosan graphene materials were compared to previously studied chitosan graphene-oxide composites in both material properties and HAB treatment. In previous studies, adsorption of the …

Identifying metabolic indicators of phytoplankton and comparing the temporal changes in algal community composition in two Lake Ontario areas of concern
… blooms transition into harmful algal blooms (HABs) when cyanobacteria produce toxins that impact ecosystem health. The point at which algal blooms transition into HABs is not fully understood, but I believe that the transition can be predicted by combining molecular and community-level …

The use of operational harmful algal bloom monitoring systems in South Africa to assess long term changes to bloom occurrence & impacts for aquaculture
… threats to aquaculture are harmful algal blooms (HABs), a natural ecological phenomenon often accompanied by severe impacts on coastal resources and local economies. There is a wide variety of potentially harmful blooming species in the region, with impacts resulting from both toxicity and the …

Effect of Increased Temperature and Nitrogen on the Non-N-fixing vs. N-fixing Cyanobacteria in Western Lake Erie: Implications for Competition and Climate Change
Harmful algal blooms (HABs) in freshwater ecosystems, especially of cyanobacterial species (cyanoHABs), are becoming more frequent and expanding geographically, threatening some of the world's largest and most-important water bodies, including Lake Erie in North America. HABs are the result of …

Application of Machine Learning Techniques to Forecast Harmful Algal Blooms in Gulf of Mexico
<p>The Harmful Algal Blooms (HABs) forecast is crucial for the mitigation of health hazards and to inform actions for the protection of ecosystems and fisheries in the Gulf of Mexico (GoM). For the sake of simplicity of our application we assume ocean color satellite imagery from the National …

Effects of hydrothermal liquefaction on algal toxins from harmful algae blooms
The formation of harmful algae blooms (HABs) in natural waters is an intensifying issue throughout the world and poses risks to the environment due in part to the toxins they release. A promising mitigation technique is to physically collect the HABs from the environment and convert them into …
