Interface of Weather and Climate: The Great Midwest Flood of 2008

AWWA Water Science, Volume 7, Issue 5, September/October 2025.
ABSTRACT Ten days of continuous torrential rain pushed warm late Spring runoff in deltaic patterns far into Lake Michigan over two subsequent months. Repeated expeditions on the RV Neeskay documented shallow lenses of plankton‐enriched water spreading across the surface at 1 km (0.6 mi) per day for months, reaching halfway across the lake, and often ...

Sulfate Reduction in Sediments Produces High Levels of Chromophoric Dissolved Organic Matter [PDF]

, 2017
Sulfate reduction plays an important role in altering dissolved organic matter (DOM) in estuarine and coastal sediments, although its role in the production of optically active chromophoric DOM (CDOM) and a subset of fluorescent DOM (FDOM) has not been ...

Autotrophic picoplankton assemblages in subtropical reservoir: temporal and vertical dynamics in abundance and biomass

Journal of Freshwater Ecology, 2017
The composition, biomass and dynamics of autotrophic picoplankton (APP, size range of 0.2–2 μm) in a subtropical reservoir (Cerrillos, Puerto Rico) were examined from January to December 2013. Samples were collected monthly in the limnetic zone.

Unique picoeukaryotic algal community under multiple environmental stress conditions in a shallow, alkaline pan [PDF]

, 2013
Winter phytoplankton communities in the shallow alkaline pans of Hungary are frequently dominated by picoeukaryotes, sometimes in particularly high abundance. In winter 2012, the ice-covered alkaline Zab-sze´k pan was found to be extraordinarily rich

A low oxygen threshold for physiological responses and trace metal quotas of Prochlorococcus and Synechococcus

Limnology and Oceanography, Volume 70, Issue 9, Page 2569-2581, September 2025.
Abstract Continued human activity is expected to accelerate ocean deoxygenation, leading to the expansion and shallowing of oxygen‐deficient zones (ODZs). This decline in oxygen may impact both phytoplankton growth and trace metal uptake. We conducted culture experiments with Prochlorococcus MIT9313 and Synechococcus XM‐24, two numerically dominant ...

Ocean acidification reduces transfer of essential biomolecules in a natural plankton community [PDF]

, 2016
Ocean acidification (OA), a process of increasing seawater acidity caused by the uptake of anthropogenic carbon dioxide (CO 2) by the ocean, is expected to change surface ocean pH to levels unprecedented for millions of years, affecting marine food web ...

Impact of nutritional history, prey quality, and quantity on grazing and photophysiological responses in the mixoplanktonic dinoflagellate Karenia brevis

Limnology and Oceanography, Volume 70, Issue 9, Page 2603-2617, September 2025.
Abstract The mixotrophic toxic dinoflagellate Karenia brevis forms red tides almost annually along Florida's Gulf coast. We hypothesize that the nutritional status and abundance of its prey, the picocyanobacterium Synechococcus, will affect its feeding rates and growth responses, with implications for bloom dynamics.

Distinct Patterns of Picocyanobacterial Communities in Winter and Summer in the Chesapeake Bay [PDF]

, 2010
In the Chesapeake Bay, picocyanobacteria were usually 100-fold less abundant in winter than in summer. However, little is known about how picocyanobacterial populations shift between winter and summer in the bay. This is due mainly to undetectable winter

Phylogenomics Untangles the Metabolic Potential of Picochlorum tauri, a New Picoalgal Species Causing a Winter Bloom in the Mediterranean Thau Lagoon

Environmental Microbiology, Volume 27, Issue 9, September 2025.
An intense green algal proliferation with severe ecological consequences occurred during the winter season in one of the largest lagoons on the French Mediterranean coast. The study contributes to the understanding of the rise and resilience of the tiny photosynthetic eukaryote, which thrived in cool waters under low solar radiance.

Sampling microbial dynamics in the Salish Sea estuary: evaluating methods to capture cyanobacteria and cyanophage

Frontiers in Marine Science
IntroductionPicocyanobacteria from the genera Prochlorococcus and Synechococcus thrive across the globe in aquatic environments, have relatively small genomes, and have growth dynamics regulated by both viral interactions and abiotic conditions, making ...
