Asian dust storms (ADSs) are the major source of dust deposition in the Northwest Pacific Ocean. To gain a better understanding on how ADSs affect the ecology of picophytoplankton in this oligotrophic region, five oceanographic cruises were conducted between March 15 and April 15, 2006 on a segment of the Kuroshio Current near the shelf break of the East China Sea (25.05° N, 123.15° E). During the study period, three ADS events were recorded and increases in nutrient concentrations as well as… 

Effect of Typhoon Morakot on microphytoplankton population dynamics in the subtropical Northwest Pacific

Satellite ocean color imagery indicates that typhoons enhance sea surface chloro- phyll concentrations along their paths. However, the influence of typhoons on microphytoplank- ton community dynamics

Spatio-Temporal Variation of Synechococcus Assemblages at DNA and cDNA Levels in the Tropical Estuarine and Coastal Waters

Synechococcus is a major contributor to global marine primary production. Here, its spatio-temporal variations in abundance and phylogenetic structure were studied at three stations of the South

Differences in the Composition of Abundant Marine Picoeukaryotes in the Marginal Sea Derived from Flooding

The transient impact of flooding on the community composition of marine picoeukaryotes (PEs, cell size ≤5 μm) in the East China Sea (ECS) was revealed in this study. In a summer without flooding

Effects of Asian dust input on eukaryotic phytoplankton community structure in the open areas in the Northwestern Pacific Ocean

ABSTRACT To study the effects of aerosol particulates originated from Asian dust on the growth of eukaryotic phytoplankton in the oligotrophic open ocean, we conducted deck-board incubation

Coastal phytoplankton responses to atmospheric deposition during summer

The northern South China Sea is subject to an increasing influence of aerosol loading, particularly over the past decades owing to the fast economic growth of mainland China. To study the response of

Impact of Contrasted Weather Conditions on CDOM Absorption/Fluorescence and Biogeochemistry in the Eastern Lagoon of New Caledonia

New Caledonia (Southwest Pacific), like all tropical Pacific Island countries, is impacted by weather events, climate change, and local anthropogenic forcing. Strong erosion of particles and

Present and future global distributions of the marine Cyanobacteria Prochlorococcus and Synechococcus

The global niche models suggest that oceanic microbial communities will experience complex changes as a result of projected future climate conditions, and these changes may have large impacts on ocean ecosystems and biogeochemical cycles.

Effect of East Asian aerosol enrichment on microbial community composition in the South China Sea

The results showed that the potential stimulus of bacteria by aerosol enrichment was likely masked by a more intense grazing pressure in these treatments, which may have implications for oceanic carbon dynamics under future scenarios of increasing atmospheric deposition.

Enhanced POC export in the oligotrophic northwest Pacific Ocean after extreme weather events

To study effects of extreme weather events (EWEs, e.g., dust storm and typhoon) on the export of particulate organic carbon (POC) measured by a floating sediment trap in the oligotrophic ocean, eight



Dynamics of community structure and phosphate status of picocyanobacterial populations in the Gulf of Aqaba, Red Sea

We monitored the genetic diversity and phosphate (P) status of Prochlorococcus and Synechococcus populations during an annual cycle (1999‐2000) in the Gulf of Aqaba, Red Sea, using DNA probes and

Influence of hydrographic conditions on picoplankton distribution in the East China Sea

An investigation was made on picoplankton distributions in relation to physical and chemical conditions in the East China Sea in July 1998, and Prochlorococcus was basically associated with oceanic warm currents, and sudden changes in cell abundance often occurred within a relatively short distance of the currents.

Basin-scale distribution patterns of picocyanobacterial lineages in the Atlantic Ocean.

Analysis of the relative abundance of Prochlorococcus ecotypes and Synechococcus lineages at the ocean basin scale along an Atlantic Meridional Transect using dot blot hybridization and fluorescence in situ hybridization techniques reveals that specific picocyanobacterial lineages proliferate in similar oceanic provinces separated by large spatial scales.

Ultraphytoplankton succession is triggered by deep winter mixing in the Gulf of Aqaba (Eilat), Red Sea

The seasonal dynamics of ultraphytoplankton for the northern Gulf of Aqaba (29”28’N, 34”55’E) were investigated in detail. Monthly analysis of pigments by HPLC and cell abundances by epifluorescence

Distribution of prokaryotic picophytoplankton from Seto Inland Sea to the Kuroshio region, with special reference to Kyucho events

A 'Kyucho' (an intrusion of warm surface water) occurs in the Bungo Channel, located in southwestern Japan. The abundances of Prochlorococcus and Synechococcus during a Kyucho, together with physical
