Surface darkening by abundant and diverse algae on an Antarctic ice cap

open access: yesNature Communications
Algal blooms play important roles in physical and biological processes on glacial surfaces. Despite this, their occurrence and impacts within an Antarctic context remain understudied.

Microcystins in components of twelve New Hampshire lakes of varied trophic status [PDF]

open access: yes, 1999
Cyanobacteria toxins, called microcystins (MCs), were found in components of twelve, stratified New Hampshire (USA) lakes of varied trophic status during the summer of 1998.

Removal of Sea Lettuce, Ulva spp., in Estuaries to Improve the Environments for Invertebrates, Fish, Wading Birds, and Eelgrass, Zostera marina [PDF]

open access: yes, 2005
Mats (biomasses) of macroalgae, i.e. Ulva spp., Enteromorpha spp., Graciolaria spp., and Cladophora spp., have increased markedly over the past 50 years, and they cover much larger areas than they once did in many estuaries of the world.

Ecophysiological perspectives of blue-green algal blooms [PDF]

open access: yes, 2001
Blue-green algae (cyanobacteria) have had a profound and unparalled impact on the aquatic environment because of the phenomenon of bloom formation. In many countries, water management is threatened with extensive and persistent noxious blooms of blue ...

Cosmopolitan and endemic species jointly enhance the potential of producing algal blooms in Tibetan glaciers

open access: yesCommunications Earth & Environment
Snow algal blooms lead to glacier and snow surface albedo reduction and subsequent melting. To explore snow algal distribution patterns and potential to cause blooms, we investigated snow algae in the Tibetan, Antarctic, Arctic, and Alps.

Spring inter monsoon algal blooms in the Eastern Arabian sea: Shallow marine encounter off Karwar and Kumbla Coast using a Hyperspectral radiometer [PDF]

open access: yes, 2010
We encountered the presence of algal blooms in the shallow coastal waters; typical of case II conditions off Karwar (Karnataka) and Kumbla (Kerala), eastern Arabian Sea during the Inter Monsoon.

Bio-Optical Environmental Assessments of Marginal Seas - Progress Report2 [PDF]

open access: yes, 2005
Algal blooms in the Mediterranean Sea have been studied by means of SeaWiFS derived (1998-2003) data on chlorophyll-like pigment concentration. Statistics of blooming anomalies, as well as comparisons with analogous data collected in situ, were used to ...

Modelling algal blooms

open access: yes, 1993
This is the final report on the research project to develop predictive models to quantify algal blooms in relation to environmental variables. The project's objectives were to develop models simulating the impact of vertical structure and mass transfer upon the dynamics of planktonic algae, including cyanobacteria, in lakes and reservoirs, to assess ...

A Eutrophication Model of the White River Basin Above Beaver Reservoir in Northwest Arkansas [PDF]

open access: yes, 1973
With national interest focused on man’s ever increasing degradation of the waters in this nation, it is clearly evident that an accurate assessment of all parameters influencing water quality needs to be made.

A turbulent diatom vs dinoflagellate phytoplankton biomass model [PDF]

open access: yes, 2013
Phytoplankton blooms play an important role in global primary productivity and the dynamics of blooms are of interest to modellers. Diatom dominated phytoplankton blooms followed by dinoflagellate blooms are common in the Southern Benguela, and are often
