Simulating snow melt inundation in urban areas

I am trying to understand how melt water from snow in urban setting gets routed. I understand that for routing rain water, one can create grid and then determine the flow direction for each cell by ...

Hypothetically, in the near future, could gas hydrate pingos erupt?

Could gas hydrate pingos erupt? If so, how quickly? And how much CH4 could they release? I'm sorry if the questions sounds silly. I'm new here and I don't know much about gas hydrates and oceanography....

Dynamic of glacier retreat? (here: in Greenland)

During the last years I have taken many pictures of obviously retreating glaciers and empty moraines in Greenland - just like this one. Looks devastating, actually. In my understanding, the current ...

How saline were the earth's oceans during the Last Glacial Maximum?

According to Wikipedia sea water is 34.7 parts per thousand salt. Between evaporation and precipitation it seems like this amount is kept largely in equilibrium but, during the last glacial maximum, a ...

Would it make sense to compare glacier fluctuations in New Zealand with Alps or Canadian rockies?

If I want to draw parallels between the glacier fluctuations between different glaciers, (considering similar size class, here, small) at a) New Zealand b) European Alps c) Canadian Rocky Mountains ...

Which depiction of the world map, with focus on dry land vs ocean do you think is more accurate? Scotese's or deeptimemaps?

Special attention paid particularly to the Arctic where the Hudson and Berent's sea are ocean in the above they are ocean, below they are land. In other places, Scotese's seems more accurate to me but ...

How is sea level rise due to a glacier melting calculated?

There's news going around (e.g. link) that the melting of the Thwaites glacier may cause sea levels to rise by 10 feet. Is that true and not exaggerated? How is the calculation made? They said the ...

Doesn't the sublimation rate on glaciers depend on the (specific) latent heat of sublimation of water ice?

On p. 6 of this article: Bliss, A.K., Cuffey, K.M., Kavanaugh, J.L., 2011. Sublimation and surface energy budget of Taylor Glacier, Antarctica. Journal of Glaciology 57, 684–696. There is an ...

What determines and confirms sensitivity of glaciers to climate change/ climate forcing?

Consider two groups of glaciers, say Group A and Group B. For simplicity, let's consider the group to fall in one size class (say 1-5 sq km), both located in the same kind of climate. We DO NOT know ...

More about hypsometry for large glaciers

I am currently reading a paper which says The elevation ranges between 1700 and 2200 m show smaller relative surface changes than the elevation ranges between 2200 and 3300 m. This has to be related ...

Is This Portion of the West Antarctic Ice Sheet Divide a Good Representation of Parallel Sided Slab on Slope Glacier

I'm trying to find data that I can use to compare to the graph in Figure 6.2 on page 88 of this source which shows temperature (found from solving the parallel sided slab on slope problem) vs height ...

How would I simulate the effects of the Antarctic ice sheet being deleted on Earth's climate?

This is a follow-up to my question If its ice sheet were removed under modern atmospheric conditions, what climatic and ice-sheet equilibrium would be re-established over Antarctica?. As it has ...

If its ice sheet were removed under modern atmospheric conditions, what climatic and ice-sheet equilibrium would be re-established over Antarctica?

Note the use of the term removed instead of melted—as in, any excess water is moved to where it can't cause trouble, either through the use of advanced technology (space elevators, et cetera) or for ...

Should I perform EOF analysis on an unevenly-spaced time series?

I have a dataset of sample concentrations of several ions/elements (Ca 2+, SO4 2-, K +, S, Ca, V, etc.) from an ice core which I am using to detect volcanic eruptions. The raw version of the dataset ...

How do you interpret Oxygen Isotope changes?

In a paper I am reading, the authors note "large (5-7%) negative shifts in the oxygen isotopic composition of geologic proxy materials" (Davis 2008, pg. 102) in several regional basins. This is then ...
