Overview and assessment
The Third Pole, like the Arctic and Antarctica, is drawing on increased attention
among the international academic communities, the decision makers and the public.
Centered on the Tibetan Plateau, the Third Pole region stretches from the Pamir and
Hindu Kush in the west to the Hengduan Mountains in the east, and from the Kunlun
and Qilian mountains in the north to the Himalayas in the south. It covers over
5,000,000 km2 in total and with an average elevation surpassing 4000 m. The Third
Pole region, with its huge geographic presence and high topography, impacts the
atmospheric circulation patterns over and beyond Eurasia. It contributes to humidity
in East and South Asia, while to aridity in Central Asia. The Third Pole environment
is currently experiencing unique changes in the cryosphere, atmosphere, hydrosphere,
and biosphere, which would seriously impact the social and economic sustainability
in the region.
The Third Pole holds the largest ice mass outside the Arctic and Antarctic regions.
These glaciers are mostly at the headwaters of big rivers such as the Yangtze, Yellow,
Brahmaputra, Mekong, Indus, Ganges, Salween Amu Darya, Irrawaddy, and Tarim
in Asia. Some of these glaciers extend north into the arid and desert region, and are
the main water sources for arid central Asia, especially for the Tarim Basin and
Qaidum Basin. Some extend south into the warmer, wetter forests and concentrate
around the Yarlung Tsangpo Rivers in the upper reaches of the Brahmaputra,
benefiting the local residents while also causing glacial disasters and other water
related problems.
Recent studies have found that glaciers in the Third Pole region are experiencing
diversified and alarming changes, with the smallest magnitude of retreat in the
interior of the region dominated by the continental climate, while the greatest one in
the southeastern Tibetan Plateau prevailed by the maritime climate. With climate
changes, glaciers are expected to experience even more dramatic changes, which
may bear large on local wellbeing of the region.
However, insufficient understandings or even misunderstandings of the
magnitude of glacial retreat and its impact on the water cycle still exist. This leads to
horrendous “forecast” of a melting-out scenario of the entire Himalayan glaciers by
2035 in the 4th IPCC report. This also leads to different interpretations of the causes
of the glacial lake expansion flood (GLEF) and glacial lake outburst flood (GLOF).
Some scientists attribute variations in glaciers and lakes to the rising temperature,
while others ascribe them to increasing precipitation and weakening evaporation.
Among the key research questions proposed by the TPE, two are directly related
to glaciers: 1) How is environmental change of the Third Pole impacting the
cryosphere (glaciers, snow and permafrost), atmosphere, hydrosphere, and biosphere?
2) What is the status of ice (glaciers, snow and permafrost) on the Third Pole and
how will glacial retreat and mass balance changes affect the water and energy cycle
and its components, and what are their environmental impacts and associated
geohazards?
During the technical meeting of Flagship Stations at the Third TPE workshop,
there were four presentations of the total seven ones talking about the glacial mass
balance flagship stations. This indicates the importance of studying glacial status in
the region. Of the seven working groups including glacier, lake, river, stable isotope,
high elevation precipitation, ecology, human activities, land-atmospheric interaction,
the scientists interested in glacier study had the common idea to hold a Glacial Mass
Balance Flagship Station Workshop.
After intensive discussion among scientists, three co-chairs organized the
workshop in Guangzhou February 19-22, 2012. The participants of the workshop
reported the ongoing mass balance studies in the Third Pole region and assessed the
status of mass balance measurement.
The workshop focused very much on the data of glacial mass balance. Profs. Yao
and Fujita and other participants pointed out that in the glacial mass balance studies
of the third pole region, the main problem we are facing is the lack of exchange of
data which results in duplicated work in some glaciers. Therefore, it is very
important to share the measuring data among different groups. Based on win-win
principles, all participants agreed to share the data they have.
The participants agreed to collect previous glaciological data to establish a
database. Data obtained from future field work will be added to the database. After
the training course in Nepal, Fujita will share the data including GPS and mass
balance data of Yala glacier and two other glaciers. Prof. Yao suggested that the
general information should be provided based on the uniform guideline.
The participants intensively discussed about the coordination of overlapping
glacial mass balance measurement. The Yala Glacier in Nepal is a good example of
coordination. There are several groups working on the Yala Glacier now. After
discussion at the workshop, Bi-annual measurements of glacial mass balance over
the glacier will be jointly carried out during pre-monsoon and post-monsoon periods
by the TPE and the academic institutions in Nepal (KU, TU and DHM). The TPE
will be responsible for pre-monsoon measurement, and the Nepalese organizations
will organize the other field observation in post-monsoon. The AWS coordination is
another good example. There are several AWSs now at Kanjing. After discussion at
the workshop, participants agreed to share the data of DHM at Kanjing station and
the TPE AWSs can be set at higher elevation.
Participants proposed that the total number and area of glaciers in Third Pole
region are unclear. Therefore, there is an urgent need to collect and compile the
glacier inventory from different countries in the Third Pole region, including China,
Nepal, India, Pakistan, Tajikistan, Afghanistan, Bhutan and Myanmar. Dr. Tayal
proposed that cross-validation of inventory is necessary to check the overlap and
missing area. Prof. Liu Shiyin will finish and publish the second Chinese glacier
inventory by the end of this year. Mr Jilani discussed the work on glacier inventory
in Pakistan. Five glaciers in Tajikistan influenced by the westerlies have been
measured by DGPS in August 2011 by TPE and will be continued.
The participants assessed the uncertainties of different methods in mass balance
studies including observations, satellite images and GPS measurement. The
participants suggest to use Landsat(TM, not ETM) images for glacier inventory in
the Third Pole region, due to its free access.
All glacial-related issues point to the necessity of long-term observation and
monitoring stations and to one of the TPE priorities, that is to establish long-term
observation and monitoring stations, particularly Glacial Mass Balance Flagship
Stations within the Third Pole region.

observations in the Third Pole region
Glacial mass balance measurement was very few before the century in the Third
Pole region. Discontinuous measurements have been carried out for the Qiyi Glacier
since the 1970s and for the Kangwure and Yala Glacier since 1990s. The Dongkmadi
Glcier and the Meikuang Glacier have been measured continuously since 1989.
Starting from 2006, glaciers for glacial measurement have been increasing. Starting
from 2006, glaciers for glacial measurement have been increasing. So far, 24 glaciers
have been discussed for mass balance measurement. The Urumqi Glacier No. 1 has
been identified as reference glacier.
1. Parlung No.10 Glacier (China/southeastern TP)
COORDINATES: 29º17´N/96º54´E
Photo taken by W. Yang, 2008
Parlung No.10 Glacier is located within the headwaters of the Parlung Zangbo River,
a tributary of the Brahmaputra River in southeastern Tibetan Plateau. It is a valley
temperate glacier flowing from 4,910 to 5,625 m, with an area of 2.1 km2 and a
length of 3.5 km. The surface is mainly exposed to the north-east. The mass balance
investigations on Parlung No.10 glacier began in the year of 2005/2006, using the
direct glaciological method in fixed period (in the end of September). A total of 11
measuring stakes have been distributed on this glacier. Recent mass balance results
show strong mass losses between 2005/06 and 2008/09, with an average of -781 mm
w.e. 2008/09 is the most negative mass balance year we have measured (-1575 mm
w.e.). The ELAs in the past four years have shifted from 5,419m to 5,500m, and
nearly reached the glacier summit in 2008/09.
2. Parlung No.12 Glacier (China/southeastern TP)
COORDINATES: 29º18´N/96º54´E
Photo taken by W. Yang, 2008
Parlung No.12 Glacier is located within the headwaters of the Parlung Zangbo River,
a tributary of the Brahmaputra River in southeastern Tibetan Plateau. It is a small
temperate cirque glacier flowing from 5,130 to 5,265 m, with an area of 0.2 km2 and
a length of 0.6 km. The surface is mainly exposed to the north-east. The mass
balance investigations on Parlung No.12 glacier began in the year of 2005/2006,
using the direct glaciological method in fixed period (in the end of September). From
1980 to 2005, the Parlung No. 12 Glacier retreated about 700 m in length and its area
reduced by approximately 55.3%. Its two branches separated from each other
sometime before 2006 and two moraine lakes emerged at its terminus. A total of 5
measuring stakes have been distributed on the right branch of this glacier. The
maximum depth of this glacier is about 40 m measured by Ground Penetrating Radar.
During field observations from 2006 to 2010, the glacier thinned by 9.5 m. The
ELAs have already risen beyond the glacier summit during the period of
measurement. This glacier is now suffering from significant mass deficit.
3. Parlung No.94 Glacier (China/southeastern TP)

number of measuring stakes over the whole glacier has progressively increased from
16 stakes in 2005 to 28 stakes in 2010. The Bn were negative for each year of the
past five balance years, but differ in magnitude significantly between years. The
2005/2006, 2007/2008 and 2008/2009 balance years show particularly high mass
deficits, while the 2006/2007 and 2009/2010 balance years show much less mass
loss. The 2008/2009 balance year stands out from the other hydrological years, with
an annual mass balance of -2018 mm w.e. The ELAs in the past five years have
shifted from 5,333m to 5,600m, and nearly reached the glacier summit in 2008/09

area of 0.96 km2, with a length of 1.8 km (Figure S10a). Its altitudinal range is
between 5,235 and 5,940 m. A total of 13 measuring stakes have been spatially
distributed on this glacier. Due to lack of measurement in 2009, we take the average
between 2008/09 and 2009/10 for 2008/09 and 2009/10, respectively. The spatial
distributions of net balance are positive almost on the whole glacier during the
period, except in 2002/03

17. East Rathong Glacier(India/ Middle Himalayas)
COORDINATES: 28°40'N/88°40'E
This glacier experiences the strongest influence of the monsoon circulation. Snow
Accumulation between June and September accounts for around 80% of annual
accumulation, because it is wet in summer due to monsoon and dry in winter. But,
the ablation season also occurs simultaneously, which leads to immediate melting of
accumulated snow. This causes difficulty in direct observations of accumulation and
ablation separately.
18. Kolahai Glacier(India/ Kashmir)

3. Proposed sites for Glacial Mass Balance
Flagship Stations in the Third Pole region
The participants discussed issues relating to glacier mass balance flagship stations
and proposed the sites.
1. Criteria for Flagship Station
Two groups of criteria are proposed:
Group one: climatic information and mass balance
1)
2)
3)
4)
5)
6)
Geographically representative, atmospheric circulation systems
Small to medium size glacier, between 2 and 10 km2
Clean, debris free and no crevasses
Easily accessible
Single branch
Ice caps should be considered
Group 2: Water resources from ice
1) Debris covered glacier
2) Large glacier
2. What to measure
Beside the Mass balance by traditional method including annual mean mass balance, specific
mass balance with altitude, accumulation area and ratio for subsequent years, ELA, stake
position map, the following measurements are recommended:
1) Ice volume by new technologies such as satellite data
2) Ice surface profile by GPS and Radar
3) Ice thickness
4) Glacial melting discharge
5) DEM Radar measurement
6) Meteorological data
7) Ice temperature
8) Ice velocity
3. How many sites to be measured
29 sites are proposed for glacier mass balance flagship stations (see the table for details).
4. Principles of implementation
1) Regular measurement at least annual
2) Inexpensive, cost-effective
3) To be carried out by the local institutions, with outside help
4) Sharing of instruments such as GPR, drill system for measuring stakes
5. Funding
Yala is funded to 2017, Rikha Samba is funded to 2015; Kizyldangi in Tajikistan is funded to
2017; Kolahoi is funded to 2014; Muztagh Ata and Gilgit will be continue to 2030; Urumqi
Glacier No.1 will be continued to around 2100. All other sites in China are funded at least to
2017. Two other sites in India and two candidate sites in Bhutan are looking for funding.
3. TPE community academic knowledge
sharing
The participants discussed about TPE community academic knowledge sharing and proposed the
following:
1) TPE mass balance data combined with other data
2) Respect the data owner and share the data after two or more years of the data acquisition
3) Data provided with the publication of papers
4) Data published should be cited on the principle of the original data provider
5) Mass balance data from china will be shared after publication
6) ICIMOD HKH cryosphere knowledge hub
7) Indian scientist will check the national data sharing policy
8) Data users properly cite the data which are published or co-author a paper.
9) With respect to Pakistan mass balance data combined with other data will be forwarded to
concerned authority in Pakistan for its international publication
10) Further discussion can be made at the forthcoming conference and workshop on cryosphere
knowledge HKH region during 14-18 May
