PlanktoScope: Affordable Modular Quantitative Imaging Platform for Citizen Oceanography

Frontiers in Marine Science, 2022
The oceans represent 97% of all water on Earth and contain microscopic, drifting life, plankton, which drives global biogeochemical cycles. A major hurdle in assessing marine plankton is the planetary scale of the oceans and the logistical and economic ...

Three-dimensional turbulence effects on plankton dynamics behind an obstacle [PDF]

Eur. Phys J. Plus 137:184 (2022), 2021
We study a predator-prey model of plankton dynamics in the two and three-dimensional wakes of turbulent flows behind a cylinder, focusing on the impact of the three-dimensional character of the carrying velocity field on population variance spectra and spatial distributions.

Long-Term Trends in Calcifying Plankton and pH in the North Sea [PDF]

, 2013
Relationships between six calcifying plankton groups and pH are explored in a highly biologically productive and data-rich area of the central North Sea using time-series datasets.

Bioprospecting Marine Plankton [PDF]

Marine Drugs, 2013
The ocean dominates the surface of our planet and plays a major role in regulating the biosphere. For example, the microscopic photosynthetic organisms living within provide 50% of the oxygen we breathe, and much of our food and mineral resources are extracted from the ocean.

The Effect of Various Salinities and Light Intensities on the Growth Performance of Five Locally Isolated Microalgae [Amphidinium carterae, Nephroselmis sp., Tetraselmis sp. (var. red pappas), Asteromonas gracilis and Dunaliella sp.] in Laboratory Batch Cultures

Journal of Marine Science and Engineering, 2021
After a 1.5-year screening survey in the lagoons of Western Greece in order to isolate and culture sturdy species of microalgae for aquaculture or other value-added uses, as dictated primarily by satisfactory potential for their mass culture, five ...

The Plankton Lifeform Extraction Tool: a digital tool to increase the discoverability and usability of plankton time-series data [PDF]

Earth System Science Data, 2021
Plankton form the base of the marine food web and are sensitive indicators of environmental change. Plankton time series are therefore an essential part of monitoring progress towards global biodiversity goals, such as the Convention on Biological ...

Response of the Ciliates Fabrea salina and Condylostoma sp. to Different Salinities and Microalgal Feeds

Ecologies, 2022
In the quest of finding local strains of marine ciliates that can be easily cultured under a broad range of salinity and fed with microalgae, Fabrea salina Henneguy, 1890 and Condylostoma sp. Bory de St.

Impacts of Microplastics on the Swimming Behavior of the Copepod Temora turbinata (Dana, 1849)

Fluids, 2020
Zooplankton are prone to the ingestion of microplastics by mistaking them for prey. However, there is a lack of knowledge about the impacts of microplastic availability on zooplankton behavior.

Planktonic communities and chaotic advection in dynamical models of Langmuir circulation [PDF]

, 1998
A deterministic mechanism for the production of plankton patches within a typical medium scale oceanic structure is proposed and investigated. By direct numerical simulation of a simple model of Langmuir circulation we quantify the effects of unsteady ...

Fungal parasitism on diatoms alters formation and bio–physical properties of sinking aggregates

Communications Biology, 2023
Fungal parasites are found to effectively control the fate of phytoplankton-derived organic matter, potentially enhancing remineralization and reducing sedimentation in freshwater and coastal systems.
