How do you calculate Sverdrups?
How do you calculate Sverdrups?
In oceanography, the sverdrup (symbol: Sv) is a non-SI metric unit of flow, with 1 Sv equal to 1 million cubic metres per second (260,000,000 US gal/s); it is equivalent to the SI derived unit cubic hectometer per second (symbol: hm3/s or hm3⋅s−1)….

What is meant by sverdrup unit?
One sverdrup is equivalent to volume transport of one million cubic meters per second. The aim of this paper is to illustrate the numbers associated with water transport over the globe in this unit.
What is Sv in oceanography?
Sverdrup (Sv) is the basic unit of volume transport used in physical oceanography and is equal to one million cubic meters of water flowing per second.
What is sverdrup theory of the oceanic circulation?
Sverdrup’s Theory of the Oceanic Circulation. ▪ The Sverdrup balance, or Sverdrup relation, is a theoretical relationship between the wind stress exerted on the surface of the open ocean and the vertically integrated meridional (north-south) transport of ocean water.
What is the difference between critical depth and compensation depth?
The Critical depth is an ecological concept applied to the whole community of plants and related to vertical mixing of the water: Page 4 4 The Compensation depth is a physiological concept: The depth at which the rate of photosynthesis for an individual plant equals the rate of respiration by that plant.
What is Ekman pumping?
The mechanism by which the effects of boundary layer momentum fluxes are communicated directly to the neighboring (essentially inviscid) fluid. The mechanism involves a forced secondary circulation referred to as Ekman pumping or Ekman suction, depending on its sign.
What is meant by 1 sverdrup discharge?
Sverdrup is a non-SI unit to quantify large-scale volume transport by oceanographers, meteorologists and atmospheric physicists. One Sverdrup is equivalent to volume transport of one million cubic meters per second.
How do you calculate transport volume?
vdz = AXHv where AX is the width of the Gulf Stream/ circumpolar current, H is the maximum depth to which the current extends and assuming that the velocity is independent of depth within this range.
How do you calculate ocean flux?
Heat flux: integral of heat*velocity over the area (here P=r w*C w*T, where T is the temperature in degrees Kelvin, and C w is the specific heat of water, i.e. C w = 4218 J/(kg.
What causes geostrophic flow?
geostrophic motion, fluid flow in a direction parallel to lines of equal pressure (isobars) in a rotating system, such as the Earth. Such flow is produced by the balance of the Coriolis force (q.v.; caused by the Earth’s rotation) and the pressure-gradient force.
How is compensation depth measured?
The compensation point, the depth where photosynthesis equals respiration can be estimated by multiplying the Secchi disk depth by about two.
Is compensation a point?
When the entire food synthesized in photosynthesis remains unutilized. Hint: Compensation point is the point at which the photosynthesis and respiration are in balance. At the compensation point, the uptake of oxygen by respiration becomes equal to the photosynthetic release of oxygen.
