In situ community dynamics influences the temperature- and light- dependent succession of seasonal phytoplankton
To assess the importance of these two parameters experimentally, microcosms were14 conducted on seven picoplankton communities (

Rivers of Brine in Antarctic Sea Ice Provide Homes for Tiny Organisms
Published in Frontiers for Young Minds
Antarctic sea ice is more than just frozen seawater at the ocean surface. It is an important home for many tiny-sized marine organisms! When seawater freezes, tiny salty rivers and streams form inside the sea ice. These are called brine channels. To live in these channels, organisms must be smaller than a pinhead. Some organisms can live their whol...
Phytoplankton responds to environmental variables in Bali Straits, Indonesia
Published in IOP Conference Series: Earth and Environmental Science
The ecological significance of phytoplankton within the small pelagic ecosystem cannot be overstated, as it serves as a vital food source for various marine biota, including larvae, juveniles, and small pelagic fish. This study marks the first investigation in the Bali Straits concerning the relationship between phytoplankton abundance and in situ ...
Importance of nanophytoplankton biomass during summer 2019 in a retreating marine-terminating glacier-fjord system, Mari...
Published in Frontiers in Marine Science
The biogeochemical dynamics of fjords around Antarctica are strongly influenced by cryospheric, climatic, and oceanographic processes that occur on a seasonal scale. Furthermore, as global climate change continues, there is a growing awareness of the impact of ocean warming on glacier melting, which is expected to affect the composition of phytopla...
Alveolate species of Mastogloia (Bacillariophyceae, Mastogloiales), including M. frickei Hustedt 1933 from Guam and two ...
Published in Botanica Marina
Mastogloia frickei Hustedt was found in Guam and studied with scanning electron microscopy. A species known by that name in Florida/Bahamas is shown to be a different species and is described as Mastogloia floridensis sp. nov. Both have alveolate striae, which is unusual in the genus. A third alveolate species was present in Florida samples and had...

The effects of sea-bottom plowing on phytoplankton assemblages: a case study of northern Hiroshima Bay, the Seto Inland ...
Published in Frontiers in Marine Science
Sea-bottom plowing is originally a method used to oxidize sediment by stirring the bottom with a trawl fishing tool, and its effect in increasing primary productivity of the water column was investigated in the western part of the Seto Inland Sea of Japan. Preliminary field sampling showed that diatom resting stage cells were abundant in the sedime...
Counteracting effects of nutrient composition (Si:N) on export flux under artificial upwelling
Published in Frontiers in Marine Science
To keep global warming below 1.5°C, technologies that remove carbon from the atmosphere will be needed. Ocean artificial upwelling of nutrient-rich water stimulates primary productivity and could enhance the biological carbon pump for natural CO2 removal. Its potential may depend on the Si availability in the upwelled water, which regulates the abu...
The V-type ATPase enhances photosynthesis in marine phytoplankton and further links phagocytosis to symbiogenesis
...
Diatoms, dinoflagellates, and coccolithophores are dominant groups of marine eukaryotic phytoplankton that are collectively responsible for the majority of primary production in the ocean.1 These phytoplankton contain additional intracellular membranes around their chloroplasts, which are derived from ancestral engulfment of red microalgae by unice...
