To understand the fate of ice algal diatoms released from fast ice, we investigated the abundance and sinking loss of diatoms and the grazing impact on diatoms by heterotrophic dino- flagellates (HD) under the ice near Syowa Station, Antarctica, during the austral summer of 2005-2006. After a rapid increase, diatoms showed a clear declining phase. Among the diatom assemblage, Porosira pseudodenticulata and Pseudo-nitzschia cf. turgiduloides were abundant in the water column but low in the…

In an effort to identify the key mechanisms controlling biological productivity and food web structure in the Chesapeake Bay estuarine turbidity maxima (ETM), we measured plankton community



Role of heterotrophic dinoflagellate Gyrodinium sp. in the fate of an iron induced diatom bloom

Iron enrichment to high‐nutrient low‐chlorophyll (HNLC) regions is being considered as a possible way of atmospheric CO2 sequestration to the deep sea. Mesoscale iron‐enrichment to the HNLC subarctic

Variation in the diatom community under fast ice near Syowa Station, Antarctica, during the austral summer of 1997/98

Variations in abundance and community structure of diatoms under the fast ice near Syowa Station were investigated almost daily during the austral summer of 199 7/9 8. Two periods of high chlorophyll

Microbial dynamics in coastal waters of East Antarctica: Herbivory by heterotrophic dinoflagellates

Values measured in the present study are tenable, comparing well with other in situ measurements, and illustrate that heterotrophic dinoflagellates play an important part in the biotic control of phytoplankton production and therefore of carbon flux through the food web of coastal waters of East Antarctica.

Population dynamics of an ice-associated diatom, Thalassiosira australis Peragallo, under fast ice near Syowa Station, East Antarctica, during austral summer

A clear shift from vegetative cells to auxospores and resting spores in Thalassiosira australis was observed in the water column and sinking fluxes under the fast ice near Syowa Station in the

Heterotrophic dinoflagellates: a significant component of microzooplankton biomass and major grazers of diatoms in the sea

Evidence is presented that phagotrophic dinoflagellates appear able to grow on diverse prey taxa and to persist at low food abundance, and that these protists may be able to survive during non-bloom conditions and then grow up when phytoplankton blooms occur.

Carbon budget of sea‐ice algae in spring: Evidence of a significant transfer to zooplankton grazers

The fate of ice-bottom algae, before and after release from the first-year sea ice into the water column, was assessed during the period of ice-algal growth and decline in Resolute Passage (Canadian

The low contribution from the fast-ice of Ellis Fjord to the phytoplankton is similar to results from other AntarcticFast-ice communities but is not necessarily reflective of processes occurring within either Antarctic or Arctic pack ice communities.

The results suggest that the pelagic food webs under the extensive ice-covered areas in coastal Antarctic regions are not short but complex.
