1. Recruitment from resting stages among bloom-forming cyanobacteria
Abstract : Cyanobacteria are known to form heavy blooms in eutrophicated freshwaters and also form resting stages, associated with the sediments, during harsh growth conditions. These resting stages can serve as inoculum for pelagic populations and function as a potential source for bloom formations. READ MORE

2. Excessive Seas : Waste Ecologies of Eutrophication
Abstract : This dissertation researches how perspectives in western industrial societies communicate about and give meaning to environmental degradation through case studies on the causes and effects of cultural eutrophication—namely nutrient pollution, algal blooms, and dead zones—in the Baltic Sea. Utilizing this approach, this dissertation addresses the ecological problems of cultural eutrophication in marine ecosystems by exposing normative claims humans make about the Baltic Sea and its contents as well as detailing how seas that exceed human expectations may offer insights into negotiating differing perspectives, discrepancies in power, and ways of being among humans and non-humans in marine environments.

3. Single-cell population genetics and dispersal limitation of a bloom-forming microalga
Abstract : Microalgal range expansions are increasing in frequency and magnitude worldwide mostly due to anthropogenic factors. However, they often remain unnoticed until mass development (algal blooms) occurs due to difficulties in detection when population densities are low. READ MORE

4. Causes and consequences of Gonyostomum semen blooms
Abstract : Aquatic ecosystems provide essential ecosystem services, but are also highly vulnerable to global change. Climate change, eutrophication and browning, for example, collectively drive the increase of harmful algal blooms in freshwaters. READ MORE

5. Optimizing Ocean Feature Estimation and Tracking through Adaptive Sampling and Formation Control of Autonomous Underwater Vehicles
Abstract : Increased ocean temperatures caused by climate change are expected to lead to more frequent and severe harmful algal blooms, which deteriorate water quality, cause human illness and fish mortality. Scientific understanding of algal blooms and their dynamics is limited due to the lack of data from such ocean phenomena. READ MORE
