'By-the-wind sailor' jellies wash ashore in massive numbers after warmer winters（图）
By-the-wind sailor jellies wash ashore massive numbers warmer winters
2021/4/9
As their name suggests, by-the-wind sailor jellyfish know how to catch a breeze. Using a stiff, translucent sail propped an inch above the surface of the ocean, these teacup-sized organisms skim along...
A long-distance connection:Polar climate affects trade wind strength in tropics（图）
long-distance connection Polar climate trade wind strength tropics
2020/12/11
It has long been recognized that variations in sea surface temperature in the tropical Pacific affect global climate. The episodic warming of the tropical Pacific during El Niño events causes the...
Dust in the wind:North Pacific Ocean fertilized by iron in Asian dust（图）
Dust wind North Pacific Ocean fertilized iron Asian dust

Vast subtropical gyres -- large systems of rotating currents in the middle of the oceans -- cover 40% of the Earth. The gyres have long been considered biological deserts, with waters that contain ver...
Two important aspects of tidal currents are (1) their temporal coherence and (2) their constancy (over centuries). The first rigorous evaluation of an Ocean Surface Current Radar (OSCR) system exploit...
Besides the measurement of ocean surface currents, high-frequency (HF) radar has also been demonstrated to be effective at measuring the wind direction at scales on the order of one to several kilomet...
A Laboratory Demonstration of Coriolis Effects on Wind-Driven Ocean Currents
Wind-Driven Ocean Currents Coriolis Effects
2015/7/20
Here we study the mechanism by which the wind drives ocean circulation. We induce cyclonic and anticyclonic circulation by blowing air over the surface of a rotating tank of water using fans co-rotati...
Modeling wind waves and wave exposure of nearshore zones in medium-sized lakes
Modeling wind waves wave exposure nearshore zones medium-sized lakes
2014/4/2
We determine wind-wave properties and estimate the wave exposure along the entire shore of Lake U¨berlingen,a subbasin of Lake Constance, using a third-generation spectral wave model (SWAN), and compa...
Effects of a wind-driven cross-shelf large river plume on biological production and CO2 uptake on the Gulf of Mexico during spring
biological production Mexico during spring
2014/4/2
The plume of Mississippi and Atchafalaya River system (MARS) is normally confined to the continental shelf
and extends westward. During March 2010, while weather in North America was dominated by unu...
Evaluating the effect of wind-driven patchiness on trophic interactions between zooplankton and phytoplankton
wind-driven patchiness trophic interactions zooplankton and phytoplankton
2014/4/17
We measured spatial patterns of zooplankton and chlorophyll concentration (a proxy for phytoplankton) with continuous sensors along horizontal transects that were repeatedly sampled (n = 150) under va...
An Experimental Study on Wind Loads Acting on a Trimaran PCC
PCC trimaran wind pressure characteristics estimation method
2011/9/9
In recent years, demands for car transportation by a ship have been increasing with favorable economic conditions in auto sector, and the need of a pure car carrier (PCC) has grown quickly. A PCC need...
Investigation on Installation of Offshore Wind Turbines
wind turbine foundation style split installation overall installation
2011/9/9
Wind power has made rapid progress and should gain significance as an energy resource, given growing interest in renewable energy and clean energy. Offshore wind energy resources have attracted signif...
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...

Nonlinear dynamics of wind waves:multifractal phase/time effects
Nonlinear dynamics of wind waves multifractal phase time effects
2009/11/16
In addition to the bispectral coherence method, phase/time analysis of analytic signals is another promising avenue for the investigation of phase effects in wind waves. Frequency spectra of phase flu...
Asymmetry of wind waves studied in a laboratory tank
Asymmetry of wind waves laboratory tank
2009/11/16
Asymmetry of wind waves was studied in laboratory tank tinder varied wind and fetch conditions using both bispectral analysis of wave records and third-order statistics of the surface elevation. It is...
