Taming Toxic Algae Blooms
The trouble began for Toledo, Ohio, in the spring of 2014, when extreme storms washed an unusually high pulse of nutrients into Lake Erie. By late summer, a massive bloom of blue-green algae, otherwise known as cyanobacteria, had shut down the city’s drinking water system. Powered by nutrients from agricultural runoff and the warm, calm summer waters, the algae spread across the lake and slowly...
متن کاملSpatial Interaction Filters for Monitoring Harmful Algae Blooms
In this paper, the authors use Spatial Interaction Filters (SIF) to simulate human experts’ visual process in tracking spatial interactive objects. The algorithm includes spatial density based pixel clustering and object interaction descriptions, such as Contact Area Index (CAI) and correlation filter. The algorithm is designed to automatically track the Harmful Algae Bloom (HAB) targets. In th...
متن کاملRecurring patterns in bacterioplankton dynamics during coastal spring algae blooms
A process of global importance in carbon cycling is the remineralization of algae biomass by heterotrophic bacteria, most notably during massive marine algae blooms. Such blooms can trigger secondary blooms of planktonic bacteria that consist of swift successions of distinct bacterial clades, most prominently members of the Flavobacteriia, Gammaproteobacteria and the alphaproteobacterial Roseob...
متن کاملLizhbeth: Toward Autonomous Toxic Algae Bloom Monitoring
With the recent increase of toxic algal blooms in lakes, biologists are looking for new sampling methods to analyze their spatiotemporal dynamics. In this paper, we present an Autonomous Surface Vessel (ASV) capable of achieving longterm sampling missions covering up to now a transect plane (1.5 km wide and 20m deep). The ASV is equipped with a probe which can be lowered via a winch to measure ...
متن کاملPhysiology, ecology, and toxic properties of marine cyanobacteria blooms
Cyanobacteria blooms in marine waters are limited to only a few taxa with Trichodesmhm, Richelia, Nod&aria, and Aphanizomenon being most commonly observed. Nonhetcrocystous, nitrogen-fixing Trichodesmium spp. are found throughout low and mid-latitude oceans and seas of the Atlantic, Pacific, and Indian Oceans, and this genus is thought to be a major contributor to new nitrogen influx into these...
