Toxicity of violacein-producing bacteria fed to bacterivorous freshwater plankton
bacterivorous freshwater plankton violacein-producing bacteria
2014/4/18
Chemical defenses have been hypothesized to be widespread among aquatic bacteria, but few studies have
assessed the susceptibility of pelagic consumers to bacterial secondary metabolites. In this stu...
We develop an age-structured model for two krill populations near the Antarctic Peninsula and estimate the
relative recruitment events that reproduce observed trends in krill abundance and age struct...
Carbon sequestration and stoichiometry of motile and nonmotile green algae
Carbon sequestration nonmotile green algae
2014/4/17
Actively motile, flagellated phytoplankton taxa often exploit vertical gradients in the availability of light and
nutrients. The ability to move actively usually goes along with low investment in str...
Towards understanding the relationship between wind conditions and plankton patchiness
Towards understanding wind conditions
2014/4/17
We used (1) water temperature (a proxy for water movement), (2) chlorophyll (a proxy for phytoplankton),
and (3) zooplankton (bulk, small, and large size classes) to investigate the relationship betw...
Modeling the duration of intermittent ice cover on a lake for climate-change studies
climate-change studies intermittent ice
2014/4/17
A generalized empirical approach to the problem of the prediction of intermittent lake ice cover for climatechange studies is presented and applied to historical ice data from Mu¨ggelsee, a shallow la...
Variability of biological production in low wind-forced regional upwelling systems: A case study off southeastern Australia
Variability of biological production regional upwelling systems
2014/4/17
Temporal variability of upwelling activity and primary production is examined for a southeastern Australian
upwelling system off the Bonney Coast (36.5uS–38.5uS, 138uE–142uE). Three indices of upwell...
Shallow water dissolution of settling calcite at Station ALOHA
settling calcite Station ALOHA
2014/4/17
The dissolution of settling calcite at the Hawaii Ocean Time-Series Sta. ALOHA in the North Pacific is
examined using a calculation of the calcite saturation state based on 5 yr of alkalinity measure...
Cross-basin comparison of phosphorus stress and nitrogen fixation in Trichodesmium
phosphorus stress nitrogen fixation
2014/4/17
We investigated the phosphorus (P) status and N2 fixation rates of Trichodesmium populations from the North
Pacific, western South Pacific, and western North Atlantic. Colonies of Trichodesmium were ...
Application of a compound controller based on fuzzy control and support vector machine to ship’s boiler-turbine coordinated control system
ship boiler-turbine coordinated system support vector machine inverse control compound control
2011/9/9
Multivariables, strong coupling, nonlinearity, and large delays characterize the boiler-turbine coordinated control systems for ship power equipment. To better deal with these conditions, a compound c...
Capacity of surface warship’s protective bulkhead subjected to blast loading
protective bulkhead blast loading energy method
2011/9/9
The protective bulkhead of the large surface warship need to be designed working in the membrane mode. In this paper, a formula is derived for calculating the plastic deformation of the protective bul...
Development and case studies of the new submarine electric sounding system
submarin electric sounding survey system analysis system marine
2009/3/5
Submarine electric sounding, which is conducted by towing a measuring cable behind a survey vessel, is a kind of electrical survey methods below sea surface. This method is applied to investigate dre...
Geoelectromagnetic observation at the seafloor—Present and future
seafloor geoelectromagnetic observation natural-source magnetotellurics controlled-source
2009/3/5
It has been almost three decades since geoelectromagnetic observation at the seafloor was enabled. The objective of this article is to make an overview of the present status of the seafloor electroma...
隐含变量新反演方法及在海洋资料中的应用
重构相空间 条件概率密度 标准化
2009/2/5
利用混沌系统单物理参量时间序列的重构相空间点条件概率密度及其标准化分析, 提出了一种新的隐含变量标准化资料的反演方法. 通过应用于Lorenz混沌系统和4维R?ssler混沌系统, 对该方法在反演相关系数的定量分析及反演功率谱的定性分析两方面进行检验, 结果表明: 该方法可靠, 简单易行, 具有较强的反演能力. 同时, 对南海的表层水温进行分析得到了南海风速的标准化资料及其功率谱.
