Sentences with phrase «based ocean mass»

Not exact matches

We don't know exactly how much plastic is floating in our oceans because of the huge mass of plastic produced in the earth on a yearly basis.

Visitors can enter models of the explorers» base camps and view a computer map of Antarctica outlining the ocean currents around the continent and the land masses and mountains that lie hidden beneath the ice.

By linking worldwide data on solid waste, population density, and economic status, we estimated the mass of land - based plastic waste entering the ocean.

The extent of the ice in the Arctic has always been very uncertain but, through this work, we show how the sea ice in the Arctic Ocean developed before all the land - based ice masses in the Northern Hemisphere were established,» Jochen Knies explains.

The only time period that remotely resembles the ocean changes happening today, based on geologic records, was 56 million years ago when carbon mysteriously doubled in the atmosphere, global temperatures rose by approximately six degrees and ocean pH dropped sharply, driving up ocean acidity and causing a mass extinction among single - celled ocean organisms.

However, if the remaining ice shelf collapses or starts losing mass more rapidly, it could effectively unplug the glaciers next to the shelf, sending land - based ice into Southern Ocean, and contributing to sea level rise.

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.

Omega - joint — based on chicken and flaxseed providing masses of absorbable Omega - 3's, as is the Omega - derm — from Vetologica, makes a big difference to some of these cats and is not depleting our oceans of fish.

Consistent with how I was reading things, pleasantly — barring some cautious hedging I'd made, based on the possibility that salinity could reflect mass changes, either when fresh water was added to the ocean via glacial melt or impoundment decreases (ocean mass increase) or via increased evaporation rates (ocean mass decrease).

This estimate is based on the carbon mass in the atmosphere and up take rates for the oceans and terrestrial biosphere.

Sea level change based on satellite altimetry is measured with respect to the Earth's centre of mass, and thus is not distorted by land motions, except for a small component due to large - scale deformation of ocean basins from GIA.

That may be true on a total mass basis, however, the comparison of the water mass versus the mass of only the top crust, that part that is visible for example, down a few kilometers, say to the depth of the deepest part of the ocean — water would be a significantly higher proportion of the mass than you have stipulated.

We know from satellite measurements that the Greenland and West Antarctic ice sheets (GIS and WAIS respectively) are losing mass in response to global warming, and that, in the case of the partly sea - based West Antarctica ice - sheet, basal melting of the ice by warmer ocean - water is likely to be a key mechanism.

We quantify sea - level commitment in the baseline case by building on Levermann et al. (10), who used physical simulations to model the SLR within a 2,000 - y envelope as the sum of the contributions of (i) ocean thermal expansion, based on six coupled climate models; (ii) mountain glacier and ice cap melting, based on surface mass balance and simplified ice dynamic models; (iii) Greenland ice sheet decay, based on a coupled regional climate model and ice sheet dynamic model; and (iv) Antarctic ice sheet decay, based on a continental - scale model parameterizing grounding line ice flux in relation to temperature.

I would suggest that a new proxy for heat being stored (or lost) from the Earth climate system be developed based on Total System Enthalpy, using a combination of moist enthalpy in the troposphere (after Pielke Sr.), ocean heat content, and total ice mass on the planet.

To conduct the research, a team of scientists led by John Fasullo of the US National Center for Atmospheric Research in Boulder, Colorado, combined data from three sources: NASA's GRACE satellites, which make detailed measurements of Earth's gravitational field, enabling scientists to monitor changes in the mass of continents; the Argo global array of 3,000 free - drifting floats, which measure the temperature and salinity of the upper layers of the oceans; and satellite - based altimeters that are continuously calibrated against a network of tide gauges.

The extent of the ice in the Arctic has always been very uncertain but, through this work, we show how the sea ice in the Arctic Ocean developed before all the land - based ice masses in the Northern Hemisphere were established,» Jochen Knies explains.

I said: - 3oC warmer oceans = mass reef death - 3oC warmer earth = very large sea level rise - acidic oceans are threat to marine life You say this is only based on models.

But we can infer the sign and (rough) magnitude of the present and past (integrated) TOA imbalance from the combined effect on ocean heat content and the mass of the land based cryosphere.

The Introduction to Levitus et al (2005) begins: Based on the physical properties and mass of the world ocean as compared to other components of Earth's climate system, Rossby [1959]...
