Periglaciation (Glaciology 🗻)

Periglaciation describes geomorphic processes that result from seasonal thawing and freezing, very often in areas of permafrost. The meltwater may refreeze in ice wedges and other structures. "Periglacial" originally suggested an environment located on the margin of past glaciers. However, freeze and thaw cycles influence landscapes...

Antarctic ice sheet (Glaciology 🗻)

The Antarctic ice sheet is a continental glacier covering 98% of the Antarctic continent, with an area of 14 million square kilometres and an average thickness of over 2 kilometres. It is the largest of Earth's two current ice sheets, containing 26.5 million cubic kilometres of ice, which is equivalent to 61% of all fresh water...

A comprehensive synthesis of satellite data reveals that the Greenland and Antarctic ice sheets lost a combined 11,309 billion metric tons of ice between 1979 and 2023.

An epishelf lake is a rare body of water where a layer of fresh water floats directly on top of denser, connected ocean salt water, trapped in place by an ice shelf acting as a dam.

⛺️ NEW: #Everest Base Camp becomes a temporary settlement of about 1,600 tents on the #Khumbu Glacier each #spring for roughly 50 days.

Heat from burned fuel and warm urine contributes to local #glacier melt, with fuel responsible for about 94% of the modeled human-caused #warming. Surface temps there are rising faster than in surrounding glacier areas, and researchers suggest the camp could be relocated.

Suncup (snow) (Glaciology 🗻)

Suncups are bowl-shaped open depressions into a snow surface, normally wider than they are deep. They form closely packed, honeycomb, often hexagonal patterns with sharp narrow ridges separating smoothly concave hollows. For a given set of suncups, the hollows are normally all around the same size, meaning that the pattern is quasi-periodic on 20–80 cm scales. The depressions are typically 2–50 cm ...

Overdeepening (Glaciology 🗻)

Overdeepening is a characteristic of basins and valleys eroded by glaciers. An overdeepened valley profile is often eroded to depths which are hundreds of metres below the lowest continuous surface line along a valley or watercourse. This phenomenon is observed under modern-day glaciers, in saltwater fjords and freshwater lakes remaining after glaciers melt, as well...

The growth and retreat of the Icelandic ice sheet over the past 230,000 years caused significant fluctuations in the seawater chemistry of the North Atlantic, specifically altering the isotopic composition of neodymium.

A recent brief period of net ice mass gain in Antarctica was driven by a temporary anomaly in tropical ocean temperatures rather than a long-term reversal of climate-driven ice loss.

Recent analyses indicate that liquid nitrogen is actively or recently rising to the surface of Pluto's Sputnik Planitia, marking the first evidence of recent liquid flows on the dwarf planet. This phenomenon creates distinct surface features comparable to meltwater channels found on Earth's glaciers.

Climate inertia (Glaciology 🗻)

Climate inertia or climate change inertia is the phenomenon by which a planet's climate system shows a resistance or slowness to deviate away from a given dynamic state. It can accompany stability and other effects of feedback within complex systems, and includes the inertia exhibited by physical movements of matter and exchanges of energy. The t...

Snow patch (Glaciology 🗻)

A snow patch, is a geomorphological pattern of snow and firn accumulation which lies on the surface for a longer time than other seasonal snow cover. Snow patches are known by a wide range of synonymous terms including snowpatches, snow beds, snow banks, and ice patches. Snowpatches are categorised by their longevity. Seasonal snowpatches melt prior to th...

Isostatic depression (Glaciology 🗻)

Isostatic depression is the sinking of large parts of the Earth's crust into the asthenosphere caused by a heavy weight placed on the Earth's surface, often glacial ice during continental glaciation. Isostatic depression and isostatic rebound occur at rates of centimeters per year. Greenland is an example of an isostatically depressed ...

Pressure ridge (ice) (Glaciology 🗻)

A pressure ridge is a linear pile-up of sea ice fragments formed in pack ice by accumulation in the convergence between floes in an oceanic or coastal environment. Such a pressure ridge develops in an ice cover as a result of a stress regime established within the plane of the ice. Within sea ice expanses, pressure ridges originate from the int...

Paraglacial (Glaciology 🗻)

Paraglacial means unstable conditions caused by a significant relaxation time in processes and geomorphic patterns following glacial climates. Rates of landscape change and sediment output from the system are typically elevated during paraglacial landscape response. When a large mass of ice melts, the newly exposed landscape is free of vegetation and is generally unstable. Often, the retreating gl...

Are you an MSc student looking for a thesis topic? Interested in Greenland/Antarctica atmosphere and ice sheet processes? Background in meteorology, geography, earth science or physics (or other quantitative discipline?

Then do I have the project for you...
I have just updated my list of open research ideas here:

https://sternaparadisaea.net/thesis-projects/

But I'm particularly at thsi stage interested in finding candidates to work on field data, satellite data, machine learning and parameterisation development and evaluation.

Not all giant icebergs, or "megabergs," release fertilizing nutrients into the ocean as they melt; their capacity to stimulate marine life and absorb atmospheric carbon varies drastically depending on their individual life cycles and histories.

Eight Swedish glaciers disappeared in 2024, expert says.

Eight of Sweden's 277 glaciers melted completely during 2024 and are now extinct due to global warming, the head of the Tarfala Research Station in northern Sweden has said.

Another 30 glaciers are at risk, glaciology professor Nina Kirchner said.

The extinct glaciers "won't come back in our lifetime and not if global warming continues", she said.

Iceberg A23a, which broke off #Antarctica in 1986 and remained grounded for over 30 years, is rapidly disintegrating as it drifts into warmer South #Atlantic waters after briefly threatening #penguin colonies near South Georgia island.

The massive #iceberg, originally twice the size of Greater #London, has shrunk to less than half its size and is expected to disappear within weeks as warmer temperatures and large waves accelerate its breakup.
