Sentences with phrase «on ocean densities»

Furthermore, by knowing the mass of a planet from radial velocity measurements and the radius of a planet based on how much starlight it blocked, it is a simple calculation to determine a planet's density, which can tell astronomers whether that planet is rocky or gaseous in nature, or whether it has a small core and a thick atmosphere, or whether it has a large core covered in deep oceans.

During a postdoctoral fellowship at MIT, Cambridge USA, his research interest focused on the interaction between ocean eddies and deep convection regions and their respective heat and density transports.

Images of the ocean first appeared in Celmins» work in 1968, with a series of graphite pencil on paper drawings that experimented with variations in the density and tone of graphite.

The oceans are stratified, warmer water floats on top of the huge volume of deeper ocean that is at maximum density and minimum temperature.

Density currents are also caused by differences in the amount of salt (salinity) on the ocean water.

Ocean water density depends on its temperature and its salinity.

Salinity changes within the ocean also have a significant impact on the local density and thus local sea level, but have little effect on global average sea level change.

Second, the ocean absorbs CO2 on average all across the lower density surface as the waters cool by radiation to space on their return to the poles.

One limitation for improving surface fluxes at all latitudes is that they have not yet been classified as essential climate variables (ECVs) or essential ocean variables (EOVs) for use by the United Nations or the Intergovernmental Panel on Climate Change, meaning that specific measurement standards have not been established for minimum spatial and temporal density of observations, accuracy, and long - term stability.

As for heat hiding in the ocean depths, one must first heat water and at the same time increase its density, otherwise it will just float on the denser, colder water below.

Even if the system did not prevent that entirely it would take many thousands of years to have any measurable effect on the oceans at all due to the huge density differential between air and water and the volume of water involved.

Ice - ocean model simulations, on the other hand, have requirements with respect to data density and quality, e.g., for observed ice thickness fields used in initialization of model runs, that are currently not being met by existing data sources (with the exception of, e.g., satellite - observed ice concentration fields).

For me, that means I'd like to see it broken down, which Coby has done well so far, by (these are just examples i'd like to see): Factors and evidence supporting or effectively debunking a) ocean acidity, which in itself has produced a number of alarming effects including less saline density in turn causing a slowing of thermohaline circulation (such as the gulf stream) b) photosynthesis - carbon sinks vs. sources or any direction that you'd like to take using what science knows CO2 to have an effect on.

Now, if you were to say looking at the salt density changes of the ocean... They do have an effect on the evaporation and precipitation on a rotational planet that have many different velocities.

In the ocean and in the lakes, the coldest particles, or rather those whose density is the greatest, are continually tending downwards, and the motion of heat depending on this cause is much more rapid than that which takes place in solid masses in consequence of their connecting power.

We assumed only that due to the biological and physical effects the ratio fabsorbed (t) / (total CO2 content of then air) is more or less constant, hence a simple response pulse response exp -LRB-- t / lifetime) is applied to the anthropic time series of coal, gas, oil and cement which have different delta13C As the isotopic signature of (CO2 natural)(t) is slowly decreasing because plants living days or centuries ago are now rotting and degassing and as molecules entered in the ocean decades ago are now in the upwellings after a slow migration along the equal density surface from the high latitudes where those surface are surfacing at depth zero, there are common sense constraints or bounds on the possible evolution of the delta13C of the natural out - gassed CO2 molecules.

It, too has significant transverse structure and is a global transporter of heat as complex currents move water around based on its temperature, salinity / density, wind direction at the surface, heat sources at depth, evaporation, the coriolis force, the shape of the ocean bottom, and freshwater contributions from e.g. rivers and melting ice.

For global average sea level, the main control on water density over these times is ocean temperature, with warming causing thermal expansion by roughly 0.4 m per degree C (Levermann et al., 2013).

Based on detailed reports of TCs that were generated in the Southern Ocean and hit Australia since 1970, from the Australian Bureau of Meteorology, Seo constructed damage estimates «using the reported financial loss, destruction of houses and capital goods, and losses of agricultural crops and livestock after a careful examination of the detailed individual cyclone reports,» which also included «local area income and population density where the storm hit.»

On the contrary, whatever warm, hypersaline water sinks below the surface because of its great density is mixed relatively quickly by winds into the upper layer of the ocean, where it transfers its heat to colder parcels by conduction.

If a crack opens up in the ocean floor down to clathrate deposits, the pressure on these deposits is reduced since the density of the sediment that formerly kept the pressure at a certain level is 2.5 times as much as the water which fills the crack.

Johnston and Lambeck (1999) concluded that a solution consistent with geological evidence, including constraints on sea level for the past 6,000 years (Section 11.3.1), is for a non-steric sea level rise (i.e., not resulting from ocean density changes) of 1.0 ± 0.5 mm / yr for the past 100 years, with 5 to 30 % originating from Greenland melting.
