Sentences with word «eustatic»

Glaciers dominate eustatic sea - level rise in the 21st century.

Eustatic change (as opposed to local change) results in an alteration to the global sea levels due to changes in either the volume of water in the world's oceans or net changes in the volume of the ocean basins.

Working with forams in UK salt marshes, the big problem is the whole teasing apart of isostatic / eustatic influences — I noted the correction for subsidence in the paper, but are you confident in not accounting for other sources?

Rates of seafloor spreading may however contribute (over geologic time) to significant eustatic sea level variation.

I guess, the they are quoting eustatic SLR, right?

The USGS, in one estimate, has stated that a total collapse of both the Greenland and Antarctic ice sheets could potentially raise eustatic sea - level 260 feet.

... The Intergovernmental Panel on Climate Change attributes about 6 cm century to melting and other eustatic processes, leaving a residual of 12 cm of 20th century rise to be accounted for.

► Eustatic sea - level rise is a change in global average sea level brought about by an increase in the volume of the world ocean.

Note that these trends may include a component of subsidence / uplift of the islands themselves and so are the numbers most relevant for local planning (not eustatic sea level change).

Hubberten, H.W., and N.N. Romanovskii, Terrestrial and offshore permafrost evolution of the Laptev sea region during the last Pleistocene - Holocene glacial - eustatic cycle, in Permafrost response on economic develoopment, environmental security and natural resources, edited by R.

On Earth, incised valleys are commonly cut and filled during falling and rising eustatic sea level, respectively.

Cross-cutting relationships are observed at the valley - scale, indicating multiple episodes of water level fall and rise, each well over 50 meters, a similar scale to eustatic sea level changes on Earth.

We obtain a value for the global, eustatic sea - level rise contribution of about 3.3 meters, with important regional variations.

We reassess the potential contribution to eustatic and regional sea level from a rapid collapse of the ice sheet and find that previous assessments have substantially overestimated its likely primary contribution.

Hamilton et al. (2001) suggested that the marine ancestors of Inia, subsequent to their divergence from Pontoporia, invaded freshwater ecosystems of Amazonia during eustatic sea - level highs of the middle Miocene, and evolved freshwater habits prior to the subsequent drop in eustatic sea - level late in the Neogene.

Our approach estimates the eustatic sea - level contribution to the palaeobathymetry curve by placing constraints on total subsidence and decompacted sediment accumulation.

A dynamic (relative to the geoid) SLR induced by the weakening of the MOC is imposed on the global steric (density - dependent) and eustatic (mass - dependent) SLRs, thereby greatly enhancing the SLR rate on the northeast coast of the U.S..

This time interval is marked by the Florida or Roman emergence in the eustatic record about the bce — ce boundary and succeeded by a transgression.

This interval, extending roughly from 1250 to 1500, corresponds to the Paria Emergence in the eustatic record and has been called one of the «little ice ages» by certain authors.

So, there is a major problem in calculating what the overall global (called «eustatic») sea level trend is — different tidal gauges suggest linear trends ranging from as much as -10 mm / year to +10 mm / yr.

[An «isostatic» sea level change is a local change, as opposed to «eustatic» or global sea level changes].
