Automatic plankton quantification using deep features [PDF]

open access: yes, 2019
The study of marine plankton data is vital to monitor the health of the world’s oceans. In recent decades, automatic plankton recognition systems have proved useful to address the vast amount of data collected by specially engineered in situ digital ...

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

open access: yesJournal 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 ...

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

open access: yesFluids, 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.

PlanktoScope: Affordable Modular Quantitative Imaging Platform for Citizen Oceanography

open access: yesFrontiers 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 ...

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

open access: yesCommunications 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.

Biological activity in the wake of an island close to a coastal upwelling [PDF]

open access: yes, 2008
Hydrodynamic forcing plays an important role in shaping the dynamics of marine organisms, in particular of plankton. In this work we study the planktonic biological activity in the wake of an island which is close to an upwelling region.

Predicting plankton net community production in the Atlantic Ocean [PDF]

open access: yes, 2009
We present, test and implement two contrasting models to predict euphotic zone net community production (NCP), which are based on 14C primary production (PO14CP) to NCP relationships over two latitudinal (ca.

The summertime plankton community at South Georgia (Southern Ocean): comparing the historical (1926/27) and modern (post 1995) records. [PDF]

open access: yes, 2008
The earliest comprehensive plankton sampling programme in the Southern Ocean was 32 undertaken during the early part of last century by Discovery Investigations to gain a 33 greater scientific understanding of whale stocks and their summer feeding ...

Plankton lattices and the role of chaos in plankton patchiness [PDF]

open access: yes, 2004
Spatiotemporal and interspecies irregularities in planktonic populations have been widely observed. Much research into the drivers of such plankton patches has been initiated over the past few decades but only recently have the dynamics of the ...
