1. Salinity, along with temperature, determines the density of seawater, and hence its vertical flow patterns in thermohaline circulation. 2. Salinity records the physical processes affecting a water mass when it was last at the surface. a. precipitation/evaporation – salts excluded from vapor b. freezing/thawing – salts excluded from ice 3.
Density is usually calculated using a mathematical function of temperature, salinity, and pressure, sometimes called an equation of state. For many years the internationally accepted...
Definition. T-S diagrams are graphic representations of two main properties of water masses: Temperature and salinity. Usually, the salinity is plotted on the X-axis and the temperature on the Y-axis. Those two properties are the main factors of a third one, the density.
15 Φεβ 2021 · Monthly Isopycnal & Mixed-layer Ocean Climatology (MIMOC): Animations show pycnocline (temperature and salinity) data of different parts of the world. The NASA animations provide views of how salinity, temperature, and density change over the course of a year.
The Equations of Oceanic Motions derives and systematically classifies the most common dynamic equations used in physical oceanography, from those describing large-scale circulations to those describing small-scale turbulence.
A T-S diagram is a graph showing the relationship between temperature and salinity as observed together at, for example, specified depths in a water column. Isopleths of constant density are often also drawn on the same diagram as a useful additional interpretation aid.
Temperature, Salinity, and Water Density. Key Ideas. Ocean water circulates in currents. Surface currents are driven by wind and affect the uppermost 10% of the ocean. Circulation of the other 90% of the ocean is driven by gravity, as dense water sinks and less dense water rises.
