Kilauea lava fuels phytoplankton bloom off Hawaii Island（图）
Kilauea lava fuels phytoplankton bloom Hawaii Island
2019/10/18
The 2018 Kilauea volcano eruption injected millions of cubic feet of molten lava into nutrient-poor waters off the Big Island of Hawaii. The lava-impacted seawater contained high concentrations of nut...
The IOC International Harmful Algal Bloom Program: History and Science Impacts
History and Science Harmful Algal Bloom Program
2015/7/8
Harmful algal blooms (HABs) have become an important subdiscipline within oceanography. Heightened attention to this topic as well as significant research advances reflect the global nature of the pro...
Spring plankton bloom hitches ride to sea's depths on ocean eddies
Spring plankton bloom sea's depths ocean eddies
2015/4/1
Just as crocus and daffodil blossoms signal the start of a warmer season on land, a similar "greening" event--a massive bloom of microscopic plants, or phytoplankton--unfolds each spring in the North ...
Grazing resistance allows bloom formation and may explain invasion success of Gonyostomum semen
Grazing resistance bloom formation may explain invasion success Gonyostomum semen
2014/4/3
The nuisance alga Gonyostomum semen (Raphidophyceae) has expanded in the Nordic countries during the last decades and can dominate lake phytoplankton communities almost completely. A possible explanat...
Increased cellular brevetoxins in the red tide dinoflagellate Karenia brevis under CO2 limitation of growth rate: Evolutionary implications and potential effects on bloom toxicity
Increased cellular brevetoxins Karenia brevis
2014/4/2
Karenia brevis blooms impair human health, marine ecosystems, and coastal economies in the Gulf of Mexico
via their production of carbon-based neurotoxins (brevetoxins), which contain no nitrogen (N)...
Large salp bloom export from the upper ocean and benthic community response in the abyssal northeast Pacific: Day to week resolution
Large salp bloom export upper ocean benthic community response abyssal northeast Pacific Day to week resolution
2014/4/2
A large bloom ofSalpaspp. in the northeastern Pacific during the spring of 2012 resulted in a major deposition of tunics and fecal pellets on the seafloor at,4000 m depth (Sta. M) over a period of 6 m...

Mg2+对Bloom综合症解旋酶与G4DNA结合的影响研究
BLM解旋酶 G4DNA Mg2+ 荧光偏振技术
2014/1/10
利用荧光偏振技术检测了Mg2+对G4DNA、BLM-G4DNA复合物和BLM642-1290解旋酶与G4DNA结合的影响．结果表明，G4DNA荧光偏振值随着Mg2+浓度的增加而增加(〖WTBX〗P〖WTBZ〗<0.01)；BLM-G4DNA复合物的荧光偏振值随着Mg2+浓度的增加出现下降—升高—下降的变化趋势(〖WTBX〗P〖WTBZ〗<0.01)；G4DNA与BLM642-1290...
Avoidance, movement, and mortality: The interactions between a protistan grazer and Heterosigma akashiwo, a harmful algal bloom species
Avoidance movement mortality
2014/4/4
A reduction in predator-induced grazing pressure may be a mechanism that facilitates the formation and
persistence of harmful algal blooms. Here, the hypothesis was tested that the heterotrophic cili...
Coccolithophore dynamics in non-bloom conditions during late summer in the central Iceland Basin (July-August 2007)
Coccolithophore dynamics non-bloom conditions late summer central Iceland Basin
2014/4/17
Measurements of primary production (PP), calcification (CF), and coccolithophore abundance were made during late summer (July-August 2007) in the Iceland Basin. Low numbers of coccolithophore cells an...
Optical Characterization of an Eddy-induced Diatom Bloom West of the Island of Hawaii
Optical Characterization an Eddy-induced Diatom Bloom West the Island of Hawaii
2010/1/21
Optical properties were collected along a transect across cyclonic eddy Opal in the lee of Hawaii during the E-Flux III field experiment (10–27 March 2005). The eddy was characterized by an intense do...
Dissolved iron (II) in the Baltic Sea surface water and implications for cyanobacterial bloom development
Dissolved iron Baltic Sea surface water cyanobacterial bloom development
2010/1/21
Iron chemistry measurements were conducted during summer 2007 at two distinct locations in the Baltic Sea (Gotland Deep and Landsort Deep) to evaluate the role of iron for cyanobacterial bloom develop...
Distribution of calcifying and silicifying phytoplankton in relation to environmental and biogeochemical parameters during the late stages of the 2005 North East Atlantic Spring Bloom
calcifying and silicifying phytoplankton environmental and biogeochemical parameters Atlantic Spring Bloom
2010/1/21
The late stage of the North East Atlantic (NEA) spring bloom was investigated during June 2005 along a transect section from 45 to 66° N between 15 and 20° W in order to characterize the contribution ...
Influence of elevated CO2 concentrations on cell division and nitrogen fixation rates in the bloom-forming cyanobacterium Nodularia spumigena
elevated CO2 concentrations cell division nitrogen fixation rates bloom-forming cyanobacterium
2010/1/21
The surface ocean absorbs large quantities of the CO2 emitted to the atmosphere from human activities. As this CO2 dissolves in seawater, it reacts to form carbonic acid. While this phenomenon, called...
