Phycocyanin detection from LANDSAT TM data for mapping cyanobacterial blooms in Lake Erie
Abstract Algorithms were developed from LANDSAT 7 ETM+ data for the July 1, 2000 overpass and LANDSAT 5 Thematic Mapper (TM) data for the September 27, 2000 overpass for Path 20 Row 31 (including… Expand

A mesoscale phytoplankton bloom in the polar Southern Ocean stimulated by iron fertilization
Changes in iron supply to oceanic plankton are thought to have a significant effect on concentrations of atmospheric carbon dioxide by altering rates of carbon sequestration, a theory known as the… Expand

Lake Superior Supports Novel Clusters of Cyanobacterial Picoplankton
ABSTRACT Very little is known about the biodiversity of freshwater autotrophic picoplankton (APP) in the Laurentian Great Lakes, a system comprising 20% of the world's lacustrine freshwater. In this… Expand

Role of iron, light, and silicate in controlling algal biomass in subantarctic waters SE of New Zealand
Phytoplankton processes in subantarctic (SA) waters southeast of New Zealand were studied during austral autumn and spring 1997. Chlorophyll a (0.2–0.3 μg L−1) and primary production (350–650 mg C… Expand

Increasing stoichiometric imbalance in North America's largest lake : Nitrification in Lake Superior
more than 600 times the mean requirement ratio for primary producers. We examine the rate of [NO3 ] increase relative to budgets for NO3 and fixed N. Nitrate in Lake Superior has continued to rise… Expand

Responses of the photosynthetic apparatus of Dunaliella tertiolecta (Chlorophyceae) to nitrogen and phosphorus limitation
Nitrogen (N) and phosphorus (P) limitation affect the photosynthetic apparatus of Dunaliella tertiolecta in markedly different ways. When grown at 0.25 d−1 (18% of the resource-saturated maximum… Expand

Phosphorus and trace metal limitation of algae and bacteria in Lake Superior
We performed a set of nutrient-enrichment bioassay experiments using metal-clean protocols, testing for macronutrient and micronutrient limitation of algae and bacteria in western Lake Superior. Our… Expand

Effects of increasing nitrogen and phosphorus concentrations on phytoplankton community growth and toxicity during Planktothrix blooms in Sandusky Bay, Lake Erie.
Sandusky Bay experiences annual toxic cyanobacterial blooms dominated by Planktothrix agardhii/suspensa. To further understand the environmental drivers of these events, we evaluated changes in the… Expand

FeCycle: Attempting an iron biogeochemical budget from a mesoscale SF6 tracer experiment in unperturbed low iron waters
[1] An improved knowledge of iron biogeochemistry is needed to better understand key controls on the functioning of high-nitrate low-chlorophyll (HNLC) oceanic regions. Iron budgets for HNLC waters… Expand

Identification, enumeration and diversity of nitrifying planktonic archaea and bacteria in trophic end members of the Laurentian Great Lakes
Oligotrophic Lake Superior and mesotrophic Lake Erie are trophic end members of the hydrologically connected Laurentian Great Lakes system, and as such exhibit different profiles of dissolved… Expand
