Rapid Subsurface Ocean Warming in the Bay of Fundy as Measured by Free-Swimming Basking Sharks
Measured Free-Swimming Basking Sharks
2015/7/17
It is widely recognized that the western North Atlantic has recently warmed very rapidly. Sea surface temperatures (SST) in 2012 were measured to be 1–3°C higher than the 1982–2011 average (Mills et a...
islands of ice: influence of Free-drifting Antarctic icebergs on pelagic Marine ecosystems
pelagic Marine ecosystems Antarctic icebergs
2015/7/15
regional warming around West Antarctica,
including the Antarctic peninsula, is related
to the retreat of glaciers that has resulted in
significant ice mass loss in recent decades
(de Ange...
Stability and consistency of nonhydrostatic free-surface models using the semi-implicit
theta-method stability accuracy artificial damping free surface nonhydrostatic pressure ocean modeling
2015/6/30
The -method is a popular semi-implicit finite-difference method for simulating free-surface flows. Problem stiffness, arising because of the presence of both fast and slow timescale processes, is eas...
Comparison of zooplankton vertical migration in an ice-free and a seasonally ice-covered Arctic fjord: An insight into the influence of sea ice cover on zooplankton behavior
zooplankton vertical migration sea ice
2014/4/16
We present observations of zooplankton diel vertical migration (DVM) over a period of 2 yr in an ice-free and
a seasonally ice-covered Arctic fjord. The contrasting environments permitted assessment ...
The effect of functional loads on free spanning pipeline’s VIV response
free spanning pipeline VIV functional load internal flow
2011/9/13
During the operation and installation of offshore pipelines, high axial forces and pressures are experienced, and their effects cannot be neglected. In this article, the effect of internal flow veloci...
Evidence for the role of methane-derived carbon in a free-flowing, lowland river food web
a free-flowing methane-derived carbon
2014/4/17
We measured the d13
C values of dominant primary consumers and their potential food sources in a
groundwater-fed lowland river. The d13
C of most consumers, such as Gammarus and Simulium, reflected...
Two-Dimensional Free Oscillations in Natural Basins
Two-Dimensional Free Oscillations Natural Basins
2009/4/3
A method is designed to calculate normal modes of natural basins. The purpose is to determine the period and configuration of free oscillations in a way that provides for the full two-dimensionality o...
Tracking a Gulf Stream Ring with a Free Drifting Surface Buoy
Gulf Stream Ring Free Drifting Surface Buoy
2009/3/7
A newly developed buoy which is free drifting and tracked by satellite was successfully used to measure the movement of a Gull Stream ring. The buoy, launched in a young ring at 36°15′N, 58°00′W, loop...
Free, Stable Continental Shelf Waves in a Sheared, Barotropic Boundary Current
Stable Continental Shelf Waves Free Barotropic Boundary Current
2009/3/7
The dispersion characteristics of stable, discrete, barotropic, continental shelf wave (CSW) modes propagating in a barotropic boundary current are strongly modified by the dynamical effects of nonuni...
Numerical Computation of Three-Dimensional Circulation in Lake Erie：A Comparison of a Free-Surface Model and a Rigid-Lid Model
Three-Dimensional Circulation Free-Surface Model Lake Erie
2009/2/23
The three-dimensional time-dependent flow in the Western Basin of Lake Erie has been calculated numerically by means of both a two-mode free-surface model and a rigid-lid model. Detailed comparisons o...
Turbulent Free Convection in Fresh and Salt Water：Some Characteristics Revealed by Visualization
Turbulent Free Convection Salt Water Visualization
2009/2/23
Tracers were used to reveal the motions within the boundary layer on water in turbulent free convection. The technique of obtaining a thin sheet of light with an inexpensive laser and a cylindrical le...

Free Topographic Rossby Waves Continental Margins Wedge
2009/2/18
An analytical model has been constructed to study the propagation of free waves of subinertial frequency in an infinite wedge filled with a uniformly stratified fluid. The problem is found to transfor...
Gulf Stream Trajectories Measured with Free-Drifting Buoys
Gulf Stream Trajectories Free-Drifting Buoys
2009/2/10
During 1975–78, 35 free-drifting buoys measured surface currents in the Gulf Stream region. The buoy trajectories trace numerous paths of the Stream and show that the Stream is strongly influenced by ...
The Free Kelvin Wave with Lateral and Vertical Viscosity
Free Kelvin Wave Lateral Vertical Viscosity
2009/2/6
Free Kelvin wave solutions of the linear shallow-water equations are described, for an f-plane. Lateral and vertical viscous effects are represented by terms ν2u and du, respectively, where (u,v) is t...
