Introduction
I am interested in nutrient limitation and biogeochemical constraints on limnetic cyanoHAB toxicity. In the past, I have researched the effectiveness of Spirogyra-based phytoremediation (algal-based phytoremediation) on reducing nutrient and coliform bacterial loads in limnetic systems.

Conference Paper
Full-text available
The Chowan River (CR)-Albemarle Sound Estuary, NC has been plagued by a resurgence of toxigenic cyanobacterial harmful algal blooms (CyanoHABs) since 2015. Both N 2-fixing and Non-N 2-fixing cyanobacteria blooms have occurred in the CR blooms and, in summer 2020, potentially harmful N 2-fixing Dolichospermum spp. was dominant. To identify the nutri...
Article
In addition to obvious negative effects on water quality in eutrophic aquatic ecosystems, recent work suggests that cyanobacterial harmful algal blooms (CHABs) also impact air quality via emissions carrying cyanobacterial cells and cyanotoxins. However, the environmental controls on CHAB-derived aerosol and its potential public health impacts remai...

GeoHealth research both characterizes and predicts problems at the nexus of earth and human systems like climate change, pollution, and natural hazards. While GeoHealth excels in the area of integrated science, there is a need to improve coordinated and networked efforts to produce open science to enable environmental justice. There is a need to re...
Article
Full-text available
This article is composed of three independent commentaries about the state of Integrated, Coordinated, Open, Networked (ICON) principles in the American Geophysical Union Biogeosciences section, and discussion on the opportunities and challenges of adopting them. Each commentary focuses on a different topic: (a) Global collaboration, technology tra...

There is a need for a unified grazing method that can be used across the freshwater-to-marine continuum. To accomplish this, this research utilized dilution grazing assays across the freshwater-to-marine continuum and across the oligotrophic-to-hypereutrophic gradient by measuring size fractions of dilution-based mortality. This was investigated by...

This article is composed of three independent commentaries about the state of ICON principles (Goldman et al. 2021) in the AGU Biogeosciences section and discussion on the opportunities and challenges of adopting them. Each commentary focuses on a different topic: Global collaboration, technology transfer and application (Section 2), Community enga...

Cyanobacterial harmful algal bloom (CyanoHAB) proliferation is a global problem impacting ecosystem and human health. Western Lake Erie (WLE) typically endures two highly toxic CyanoHABs during summer: a Microcystis spp. bloom in Maumee Bay that extends throughout the western basin, and a Planktothrix spp. bloom in Sandusky Bay. Recently, the USA a...

Coastal North Carolina experienced 36 tropical cyclones (TCs), including three floods of historical significance in the past two decades (Hurricanes Floyd-1999, Matthew-2016 and Florence-2018). These events caused catastrophic flooding and major alterations of water quality, fisheries habitat and ecological conditions of the Albemarle-Pamlico Sound...
Poster
One major threat to freshwater systems is the proliferation of toxic cyanobacterial harmful algal blooms (cyanoHABs). A prolific group of cyanotoxins, the microcystins, is enriched in nitrogen (N), and their synthesis is thought to be linked to N availability. There is a need to investigate the potential roles a major watershed N source; N fertiliz...
Patent
Full-text available
The disclosure describes an algal system for improving water quality through the use of algae. In example embodiments, the algal system comprises an elongate device including algae enclosed therein and capable of reducing at least the levels of nitrates and phosphates in water directed through the device. The algae may be capable of also reducing E...

The freshwater alga Spirogyra grevilleana was used in an experimental biofiltration system to reduce levels of Escherichia coli, nitrates, and phosphates. Water collected from a 2.32 ha lake in Atlanta, Georgia, USA was pumped at a constant rate ( m3 hr-1) through the algal filtration devices with low and high concentrations of S. grevilleana. Effl...

Project
The goal of the project is to use 15N compound specific N analysis to measure N incorporation into microcystins, a prominent, high-N cyanotoxin. This will help determine if speciation of N drives toxicity of cyanoHABs.
Archived project
The goal of this project is to understanding the use of Spirogyra algae as algal-based phytoremediation for improving water quality.
