Glossary ... for newbies and others
« on: March 23, 2013, 04:49:39 PM »
I realized that it may be difficult for our new readers to understand most of abbreviations used here. So I suggest making a glossary !

For more terms you can refer to NSIDC's Glossary. Or peruse the Global Croysphere Watch Glossary (4141 entries from 26 sources; over 2200 are unique).

Please add terms and definitions below, I'll try to compile them in this first message (except the jokes). Please also provide links when you can.

An other Glossary is available for Antactic here

AO - Arctic Oscillation

AW - Atlantic water

ASI - Arctic Sea Ice - all the Ice floating in the Arctic Seas.

The Antarctica Main Glaciers (or Ice Streams)

*FRIS - Filchner-Ronne Ice Shelf, Atlantic part of WAIS (Filchner the eastern outlet, Ronne the western by the peninsula (both having gently sloping submarine outlets)
*RIS - Ross Ice Shelf, Pacific part of WAIS (with at least 3 gently sloping submarine outlets)

The 'backdoors'(aka 'weak underbelly') to both of them (There's a gap in the Antarctic Mountains) are:
*PIG - Pine Island Glacier, Blocking one specific steep and deep outlet of WAIS below sea level, and the other sensitive outlet nearby is
*Thwaites glacier. These are also the most northern outlets of  the

*WAIS - The whole West Antarctic Ice Sheet

for 'completeness' sake...
*EAIS - East Antarctic Ice Sheet with two largest outlets
*Mertz Glacier (that shed the C-28 iceberg just 2010) and
*Lambert Glacier (to
*Amery Ice Shelf towards Indian Ocean)
and numerous minor ones (most sit firmly on rock.)

OK, first set of compilation done (jokes apart).

Please add links when you can...

I'd also love to have clear and simple graphs about :
- AO and AMO,
- extent and area,
If anyone can provide some images or links ? Perhaps on Wikipedia ?

Ivica, what is ZIS ?? Never read about this...

Common chemical abbr.

CO2 = Carbon Dioxide

CH4 = Methane

SO2 = Sulfur Dioxide

Methane Clathrate =  Methane Yydrate, Hydromethane, methane ice, fire ice, natural gas hydrate, or gas hydrate. A solid clathrate compound (more specifically, a clathrate hydrate) in which a large amount of methane is trapped within a crystal structure of water, forming a solid similar to ice (CH4•5.75H2O)

Common Mass/Volume abbr.

ppm = parts per million (mass/molar fraction)

mkm2 = one million square kilometers

Mt = Megatonne = one million metric tonnes (unit of mass) = MMT (million metric tonnes)

Gt = Gigatonne = one billion metric tonnes (unit of mass) i.e. 24.5 GtCO2 (twenty four billion, five-hundered million tonnes of carbon dioxide)

km3 = one cubic kilometer (unit of volume)

1 km3 of water = 1 kGt of water
1.0 km3 of ice = 0.90 Gt

Common Weather abbr.

hPa = 100 Pascals (unit of pressure) = 100 N/m2 (100 Newtons per square meter) Normal pressure usually borders around 1000 hPa

kPa = 1000 Pascals

Bar = 100,000 Pa or 1000 hPa or 100 kPa

millibar = Mbar = 0.001 of a Bar

albedo: the reflectivity of a surface, measured as the ratio of reflected light to incident light, with 0 indicating perfect absorption and 1 indicating perfect reflection. http://en.wikipedia.org/wiki/Albedo

Useful reference values:

.04 charcoal
.50-.70 sea ice
.80-.90 fresh snow

It doesn't work like that. 

For SIE, the sensor looks at a given pixel of ice and measures the percentage of ice within that pixel.  If it's over 15%, then it counts as ice, and if it's below 15% it counts as open water.

So in theory, you could have  a pixel that's 15.00001% covered in ice, and there happens to be a 100 metre square polynya within the ice-covered part, which would push it down below the threshold and thus the whole pixel would now be counted as water.

Alternatively, you could have a long thin polynya (say a crack that's 1km wide and 50km long) that stretches across multiple pixels but doesn't bring any of them below the 15% threshold, in which case it would be entirely missed by the SIE measure.

Sea ice area weights each pixel by the percentage coverage, and so will in theory pick up polynyas of any size, no matter how big or small - however that measure is easily confused by melt ponds.

Hi chalambar, and welcome.

Export is transport of ice floes out of the Arctic Ocean towards the Atlantic Ocean through Fram Strait (between Greenland and Svalbard) and Victoria Channel (between Svalbard and Franz Josef Land) where waters are warmer and the ice melts completely.

There can also be some export through Nares Strait towards Baffin Bay, or through the channels and straits of the Canadian Arctic Archipelago, but melting out is not guaranteed.

Next time ask under The Forum in the Off-topic Category, please.

What does "Charctic" mean?  As in "Charctic SIE loss today is 1.63 million Km^2"
and http://nsidc.org/arcticseaicenews/charctic-interactive-sea-ice-graph/

There are some other funny jargon words used on this blog.  Sure wish folks who use them would define them here!

a low resolution labeled picture showing which areas of the arctic are refereed to by each of the area graphs would be nice

as eg : https://en.wikipedia.org/wiki/Barents_Sea doesn't list actually what area is talked about, but we're quite happy to list the amount of ice in it at https://sites.google.com/site/arcticseaicegraphs/regional

perhaps something like a labeled version of the following?

For my work on regional area and extent I needed a name for ice that is not in those 14 well-known regions. Instead of lumping them as  "other", I defined a few more regions (inspired by NSIDC's MASIE).

Extra regions are:

pacf: Open Pacific Ocean     
japn: Japanese/Yellow Sea       
alsk: Gulf of Alaska             
atln: Open Atlantic Ocean     
main: Gulf of Maine             
balt: Baltic Sea                 
lake: Lakes

The lakes should have been defined anyway as a separate domain anyway, IMO.

And add to that the acronyms that had me baffled in the beginning:
ESS = East Siberian Sea
CAA = Canadaian Archipelago
CAB = Central Arctic basin

I've added CAB. The other two were already in there.

CAA is the Canadian Arctic Archipelago, for those interested in the detail.

FJL - Franz Josef Land
WLA - ? (http://forum.arctic-sea-ice.net/index.php/topic,1493.msg73948.html#msg73948)


Does anyone use FJL as an acronym? I've added it to the glossary nonetheless. Yes, and I saw that WLA too and had no idea what it meant.  :D

Kann es sein dass Plinius vergessen hat dass hier nicht deutsch gesprochen wird? WLA koennte WarmLuftAdvection  heissen.

my guess is that WLA is the german for Warm Air Advection

Das wäre schon möglich, Andreas!

From the context I figured he meant something along those lines.

Hello,

Could you also explain what is the lower line in the JAXA AMSR2 Artic Sea Ice Melt and total extend made by Wipneus ?
Thanks,

Etienne

Hi Etienne,

The answer is in the Home brew AMSR2 thread, and in my latest blog post on the ASIB. Basically it's a graphical display of the blue and grey on those JAXA maps that show where the surface is melting.

Cheers,

Neven

Sea Ice Glossary
by C. A. Linder and associated with a 2003 expedition to the far South.

Defines about 30 types of sea ice and related terms, but doesn't include melange!
