Image processing for smart browsing of ocean colour data products and subsequent incorporation into a multi-modal sensing framework [PDF]

open access: yes, 2010
Ocean colour is defined as the water hue due to the presence of tiny plants containing the pigment chlorophyll, sediments and coloured dissolved organic material and so water colour can provide valuable information on coastal ecosystems.

Thresholds of terrestrial nutrient loading for the development of eutrophication episodes in a coastal embayment in the Aegean Sea [PDF]

open access: yes, 2008
Thresholds of terrestrial nutrient loading (inorganic N and P) for the development of eutrophication episodes were estimated in an enclosed embayment, the gulf of Kalloni, in the Aegean, Eastern Mediterranean.

Algal Blooms in Lakes Increase After Wildfire Smoke Events in the Contiguous United States

open access: yesGlobal Change Biology Communications, EarlyView.
Temporary pulses of surface chlorophyll‐a are identified following wildfire smoke events in lakes and reservoirs across the United States. ABSTRACT Area burned by wildfire has increased in the contiguous United States and in many places globally in recent years, impacting communities and ecosystems nearby and even far downwind of fires. We examined the

Responses of nuclear receptor HR96 to the toxic dinoflagellate Prorocentrum lima in Crassostrea ariakensis

open access: yesEcotoxicology and Environmental Safety
Diarrhetic shellfish toxins (DSTs) are widely distributed and the most common algal toxins and their metabolic detoxification mechanism in shellfish remains poorly understood.

Drivers and food web effects of Gonyostomum semen blooms [PDF]

open access: yes, 2013
The flagellate Gonyostomum semen forms dense late-summer blooms in humic lakes and is a nuisance to swimmers because it forms a slimy coat on the skin, causing irritation in sensitive individuals. Increasing occurrence and bloom incidence of G. semen has

Cyanobacteria blooms cannot be controlled by effective microorganisms (EM) from mud- or Bokashi-balls [PDF]

open access: yes, 2002
In controlled experiments, the ability of ‘‘Effective Microorganisms (EM, in the form of mudballs or Bokashi-balls)’’ was tested for clearing waters from cyanobacteria.

Review of Harmful Algal Blooms in the Coastal Mediterranean Sea, with a Focus on Greek Waters

open access: yesDiversity, 2021
Anthropogenic marine eutrophication has been recognized as one of the major threats to aquatic ecosystem health. In recent years, eutrophication phenomena, prompted by global warming and population increase, have stimulated the proliferation of ...

What is “accuracy”? Rethinking machine learning classifier performance metrics for highly imbalanced, high variance, zero‐inflated species count data

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Machine learning has opened the door for the automated sorting (classification) of images, holograms and acoustic backscatters of individual plankton, invertebrates, fish and marine mammals. However, this field is complicated by decades of paradoxically promising reports of classifier performance that do not correlate with real‐world uptake of

Polystyrene microplastics exacerbated the toxicity of okadaic acid to the small intestine in mice

open access: yesEcotoxicology and Environmental Safety
Microplastics (MPs) and okadaic acid (OA) are known to coexist in marine organisms, potentially impacting humans through food chain. However, the combined toxicity of OA and MPs remains unknown.

HABNet: Machine Learning, Remote Sensing-Based Detection of Harmful Algal Blooms

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
This article describes the application of machine learning techniques to develop state-of-the-art detection and prediction system for spatiotemporal events found within remote sensing data; specifically, harmful algal bloom (HAB) events.
