Sentences with phrase «glacial rebound»

So you've gone through and looked at all the individual tidal gauges, corrected for local effects like post glacial rebound from the last ice age, local subsidence due to soil compaction or groundwater removal, local soil buildup due to tidal or river silt deposition, discontinuities due to earthquakes, and the like?

Greg, «In theory glacial rebound can not be accelerating.

(In theory glacial rebound can not be accelerating.

Similarly other Zwally detractors pointed to papers such as Harig 2015 that claimed Antarctica was losing ice, but Harig 2015 used GIA models that were well known to over-estimate glacial rebound.

I realize that tidal gauge measurements for assessing sea level rise has met with some skepticism because of multiple measurement issues including tides, ground water pumping and subsidence, tectonic plate movement, glacial rebound, etc..

While it is said by NOAA sea levels rise by 1.7 - 1.8 mm per year, for coastal stations that is wrong, because NOAA adds 0.3 mm to allow for ocean floor lowering due to post glacial rebound, while this might be correct, for coastal stations the effect is more like 1.5 mm per year.

Any study of sea level needs to take into account deposition and erosion, land movement often through post glacial rebound - and tectonic activity, as these can cloud the picture.

e.g. models of eustacy («worldwide change of sea level as contrasted with local diastrophic uplift or subsidence of the land») vs isostacy (glacial rebound following glaciation / melting) vs local sinking / rising from glaciation / interglacial warming, CO2, and / or solar variations, and their causes.

Angech — Glacial rebound and subsidence not a general concern?

Oddly when sea level is calculated those declining trends Arctic ocean sea levels are typically ignored because some argue it is due to glacial rebound.

The two areas will proabaly continue to lead due to glacial rebound and tectonic movement.

If you truly believe there is a significant rise in sea level (and compensation required by «glacial rebound») then certainly these classified datasets should show the impact of 50 years of warming.

Also the error bars went away at some point even though glacial isostatic rebound is relatively new and would affect tide gauge readings prior to satellite measurement (i.e. how glacial rebound was discovered).

Wilson said that such extreme differences in mantle properties are not seen elsewhere on the planet where glacial rebound is occurring.

Not exact matches

Thomas @ 2: glacial isostatic rebound in North Carolina is essential to this research (the land there is sinking at ~ 1 mm per year, which means that there is a steady background sedimentation rate).

Some groups have tried to develop models of the rebounding land, so that sea level researchers can apply «Glacial Isostatic Adjustments» (GIA) to their data to correct for the effects.

Post-glacial rebound - The vertical movement of the land and sea floor following the reduction of the load of an ice mass, for example, since the Last Glacial Maximum (21 ka).

The area must have experienced tremendous rebound from depression by glacial ice over the past 12,000 years.]

Most GIA models assume Antarctica has been rebounding upwards since deglaciation removed the weight of glacial ice.

The comments above the Peltier's ICE - 5G glacial isostatic rebound model which has sea depth decreasing at 0.3 mms / year takes a slight beating in the paper.

Fleming, K. & Lambeck, K. Constraints on the Greenland Ice Sheet since the Last Glacial Maximum from sea - level observations and glacial - rebound Glacial Maximum from sea - level observations and glacial - rebound glacial - rebound models.
