For smaller oysters with crisp, clean flavors, you'll want oysters from colder, cleaner
waters and narrower, smaller waterways, she says: «Think:
glaciers and fjords, places
where you can see through the
water.
This warm
water reaches the coastline in places,
where it triggers substantial melting of the floating parts of
glaciers and leads to thinning of the ice upstream.
Glaciers deliver that ice from the inner reaches of the continent to the ocean,
where massive frozen shelves float atop the
water.
«We still don't know exactly
where the meltwater came from, but given that the average temperature at the nearest weather station has risen by about 1.5 degrees Celsius (2.7 degrees Fahrenheit) over the last 50 years, it makes sense that snow and ice are melting and the resulting
water is seeping down beneath the
glacier,» Thompson said.
He recently took that experience to Nepal,
where he collected
water samples from the Himalayan
glacier - fed Kosi River as part of an expedition led by the Mountain Institute.
But reliable data on how much
water the
glaciers release or
where that
water goes have been difficult to develop.
Based on his experience in the Rio Santa —
where it was once assumed that 80 percent of
water in the basin came from
glacier melt — Mark said he expects to find that the impact of monsoon
water is greatly underestimated in the Himalayas.
«If you haven't had proximity to these
glaciers, if you haven't thought about
where water comes from, it would be easy to understate or underestimate the implications of glacial ice loss in a state that has predominantly a semi-desert climate and certainly by contemporary climate models is going to be pretty significantly impacted by climate change,» said Jacki Klancher, a professor of environmental science at Central Wyoming College.
«We predicted in our study that most
glaciers will be gone or much diminished by the end of the century — so
where will the
water come from in the dry season?
«
Where mid-depth
waters from the deep ocean intrude onto the continental shelf and spread towards the coast, they bring heat that causes the
glaciers to break up and melt.
The most obvious example of this is the case of calving
glaciers where their gross behaviour may relate more to
water depth at the calving front than small - scale climate variations.
Because, and this is the crux of the new paper, scientists have discovered deep channels
where warmer
water can flow right under the
glacier.
Where the face of a
glacier meets the ocean, warm
water can melt it
They found signs that ocean
water is pushing miles deeper under the ice than we realized in near a location
where both
glaciers meet, raising some uncomfortable prospects about how their futures could be intertwined.
French Prime Minister Manuel Valls visited the Mer de Glace (the Sea of Ice) Friday on Mont Blanc,
where the retreating
glacier has been documented for more than a century, through
water colors painted before the invention of the still camera, black - and - white photos depicting a then - modern steam locomotive chuffing alongside the ice and today's high - definition satellite photos.

Stop in breathtaking Lake Louise,
where cold
waters mirror the surrounding mountains and
glaciers.
Other factors would include: — albedo shifts (both from ice >
water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly warm, rain fall on ice; — «stuck» weather systems bringing more and more warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of
glaciers; — sea
water getting under parts of the ice sheets
where the base is below sea level; — melt
water lubricating the ice sheet base; — changes in ocean currents -LRB-?)
The most obvious example of this is the case of calving
glaciers where their gross behaviour may relate more to
water depth at the calving front than small - scale climate variations.
IPCC AR4 WG1 SPM says (under «Fresh
water resources and their management» of «C. Current knowledge about future impacts») In the course of the century,
water suppries stored in
glaciers and snow cover are projected to decline, reducing
water availability in regions supplied by meltwater from major mountain ranges,
where more than one - sixth of the world population currently lives.
in a SciAm Item for the fact that a series of under - the - icesheet Volcanoes were causing the emmisions of large quantities of
water from under the edge of the
glaciers,
where they meet the sea, and the fact that these eruptions were causing rapid advances in the sheets march toward the sea.
I'm thinking that ice floats (esp in salt
water, I suppose), and since this
glacier bed is below sea level, and if sea
water were to get into it (or even at front edge points
where it meets the sea), a rising sea level might put even more upward pressure on the
glacier.
The stunning documentary «Chasing Ice» conveys the drama and mystery in all that melting, and the impact of warmer sea
water on the areas
where Greenland's
glaciers meet the sea.
At this point, the hotter
waters are locked below the surface
where they go to work eating away at the
glacier base.
The
glacier goes afloat at the grounding zone
where bedrock, till, and ice meet the ocean
waters about 600 meter below sea level (Rignot, 1996).
Notably, the only region within Baffin Bay
where we currently see cooler surface
water is in the major
glacier melt zone near Jakobshavn.
Kelly D. Alley: The Himalayas is a place of majesty
where glaciers hug the world's tallest mountains, snow melt and precipitation combine to form the
water of many vibrant river systems, and millennia of cultural and linguistic diversity guide human life ways.
In the Nigardsbreelva watershed in Jostedalen,
where 75 percent of the catchment area is covered by
glacier,
water flow approached flood levels throughout much of August.
In the Amundsen Sea Embayment region of West Antarctica,
where glaciers terminate in the ocean and extend over the
waters via floating ice tongues, six major
glaciers are experiencing rapid rates of retreat.
While I am sure some of the
glaciers drain toward the drier areas of Pakistan and Afganistan, these are not the areas
where 2 billion people were supposed to have their
water supply threatened (India and S China).
In the course of the century,
water supplies stored in
glaciers and snow cover are projected to decline, reducing

Algae grow on other ice surfaces in areas such as the Himalayas,
where they reside on
water - producing
glaciers.
Ice has a huge albedo compared to everything else, and represents an enormous reservoir of cold fresh
water deposited on continent - sized chunks of the globe (not to mention winter snowfall in regions
where it isn't «permanent» and
glaciers where it is).
One result is that the
water that traditionally evaporated from the Southern Ocean and rained down over New South Wales is now being pulled back into Antarctica — drying out the southeastern quadrant of Australia and contributing to the buildup of
glaciers in the Antarctic — the only area on the planet
where glaciers are increasing.
Cryosphere All regions on and beneath the surface of the Earth and ocean
where water is in solid form, including sea ice, lake ice, river ice, snow cover,
glaciers and ice sheets, and frozen ground (which includes permafrost).
«Most

We are already seeing the effects of this in Peru
where severe
water shortages have followed the melting of Andean
glaciers.
We know it from direct measurements of land and
water, from shifts in
where animals and plants live, from rapid increases in
glacier and ice sheet melt, from sea level rise (due less to melting ice, and more to expansion as the
water warms).
We need to know, because it is these strong currents at 200 to 300 meter depth that move the heat of warm and salty Atlantic
waters towards coastal
glaciers where they add to the melting of Greenland.
Finding out
where the ducks were retrieved might help the experimenters figure out
where water flowing beneath the
glacier ends up.
This
water then serves as a lubricant between the
glacier and the earth underneath it, allowing the
glacier to shift to lower, warmer altitudes
where more melt would occur.

Thus we have berm, a lovely word for a longish mound used for landscaping; pingos, if you're up north,
where they'll be rather large conical upthrusts of ice covered with some soil (and, of course, given the yin / yang of this business, further south also a circular depression typically filled with
water); further south still you'll trip over drumlins, formations made up of till left by receding
glaciers, and not to be confused with eskers, which seem to have formed within holes inside
glacier.
