More than 100 years of Arctic sea ice volume reconstructed from ships' logbooks（图）
Arctic sea ice volume reconstructed ships logbooks
2019/10/21
Our knowledge of dwindling sea ice coverage in the Arctic Ocean comes mostly through satellites, which have imaged sea ice from above since 1979. The University of Washington Pan-Arctic Ice Ocean and ...
Ships Passing in the Night or a Marriage Made in Heaven?
Ships the Night Marriage Made Heaven
2015/8/4
This issue of Oceanography celebrates a seminal event: the joint conference of The Oceanography Society (TOS) and Oceanology International Americas 2001 (OIA2001). The TOS membership is intimately fam...
The ocean has provided an important means of commerce and transport for centuries and does so to this day. With the ocean covering roughly 70% of Earth's surface, much maritime activity occurs well ou...
Leonhard Euler and the Theory of Ships.
The Arctic is home to a growing number of whales and ships, and to populations of sub-Arctic whales that are expanding their territory into newly ice-free Arctic waters.
Chaotic Roll Motions of Ships in Regular Longitudinal Waves
parametric resonance Lyapunov characteristic exponents longitudinal waves.
2011/9/9
Parametric resonance can lead to dangerously large rolling motions, endangering the ship, cargo and crew. The QR-factorization method for calculating (LCEs) Lyapunov Characteristic Exponents was intro...
Uncertainties in wind speed dependent CO2 transfer velocities due to airflow distortion at anemometer sites on ships
wind speed dependent CO2 velocities airflow distortion anemometer sites ships
2010/8/13
Data from platforms, research vessels and merchant ships are used to estimate ocean CO2 uptake via parameterisations of the gas transfer velocity (k) and measurements of the difference between the par...
Applying the vantage PDMS to jack-up drilling ships
Vantage PDMS component database rate database bolt jack-up drilling ships
2011/9/13
The plant design management system (PDMS) is an integrated application which includes a database and is useful when designing complex 3-D industrial projects. It could be used to simplify the most dif...

Update on emissions and environmental impacts from the international fleet of ships: the contribution from major ship types and ports
international fleet of ships major ship types ports
2009/3/31
A reliable and up-to-date ship emission inventory is essential for atmospheric scientists quantifying the impact of shipping and for policy makers implementing regulations and incentives for emission ...
Classifying ships by their acoustic signals with a cross-bispectrum algorithm and a radial basis function neural network
acoustic vector signal cross-bispectrum feature extraction RBFNN ship classification
2011/9/9
An algorithm for estimating the cross-bispectrum of an acoustic vector signal was formulated. Composed features of sound pressure and acoustic vector signals are extracted by the proposed algorithm an...
Research on roll stabilization for ships at anchor
at anchor anti-rolling lift-generation model fluent simulation
2011/9/14
With the increasing importance of ocean exploitation,providing anti-rolling stability for ships at anchor has become more and more important. The lift-generation theory of traditional fin stabilizers ...
Global model simulations of the impact of ocean-going ships on aerosols, clouds, and the radiation budget
ocean-going ship aerosol cloud radiation budget
2008/12/22
International shipping contributes significantly to the fuel consumption of all transport related activities. Specific emissions of pollutants such as sulfur dioxide (SO2) per kg of fuel emitted are h...
