Vertical distribution and ontogenetic ‘‘migration’’ in coral reef fish larvae
migration reef fish larvae Vertical distribution
2014/4/16
Vertical distribution patterns were studied in the community of coral reef fish larvae around Tetiaroa (French
Polynesia) using vertically stratified net tows within the first 100 m of the water colu...
The effect of CO2 on the photosynthetic physiology of phytoplankton in the Gulf of Alaska
CO2 the photosynthetic physiology phytoplankton the Gulf of Alaska
2014/4/16
In the high-nutrient, low-chlorophyll waters of the Gulf of Alaska, microcosm manipulation experiments were used to assess the effect of CO2 on growth and primary production under iron-limited and iro...
Aquatic metabolism in the Everglades: Dominance of water column heterotrophy
water column heterotrophy Aquatic metabolism
2014/4/16
Using high-frequency measurements of free water dissolved oxygen (O2), we assessed gross primary production
(GPP), respiration (R), and net aquatic production (NAP) in the shallow-water Everglades pe...
Molybdenum–nitrogen co-limitation in freshwater and coastal heterocystouscyanobacteria
coastal heterocystous cyanobacteria
2014/4/16
Molybdenum (Mo) is essential for the biological assimilation of inorganic nitrogen (N). We compared Mo
requirements for N2
-fixation in two species of filamentous heterocystous cyanobacteria (HC) to...
Oxygen isotopic exchange and fractionation during bacterial ammonia oxidation
fractionation during bacterial ammonia oxidation Oxygen isotopic
2014/4/16
We examined the oxygen isotopic systematics for ammonia oxidation, the first step in the regeneration of
nitrate from ammonium. In particular, oxygen isotopic fractionation and exchange with water we...
Dynamics of organic-aggregate–associated bacterial communities and related environmental factors in Lake Taihu, a large eutrophic shallow lake in China
organic-aggregate–associated aihu a large eutrophic shallow lake
2014/4/16
To investigate the spatial and temporal variations of organic-aggregate–associated bacterial communities
(OABC), a 25-month observation was conducted at two contrasting sites (Meiliang Bay and the la...
Fully Nonlinear Shallow Water Waves Simulation Using Green-Naghdi Theory
Green-Naghdi theory model fully nonlinear water waves shoaling waves
2011/9/8
Green-Naghdi (G-N) theory is a fully nonlinear theory for water waves. Some researchers call it a fully nonlinear Boussinesq model. Different degrees of complexity of G-N theory are distinguished by “...
Modeling Loads Caused by Breaking Waves Striking Vertical Walls
vertical breakwater breaking wave wave loads particle imaging velocimetry (PIV)
2011/9/9
Breaking waves can have tremendous destructive impact on vertical walls, yet they are poorly understood. By using particle imaging velocimetry (PIV) technology and high-precision pressure transducers,...
A Feasibility Study on a New Trimaran PCC in Medium Speed –Performance in Still Water and Strong Wind
trimaran Pure Car Carrier EHP drift angle speed reduction
2011/9/9
In the present paper, a new trimaran Pure Car Carrier (PCC) is proposed and a feasibility study on the ship is carried out. In this study, first, the effective horse power (EHP)/car of the PCC running...
A finite volume algorithm based on overlapping meshes for simulation of hydrodynamic problems
