Dear all,


We hereby invite you to submit abstracts for the "Mean Surface & Marine Geoid, Bathymetry" session of the scientific Symposium on "20 Years of Progress in Radar Altimetry" that will take place in Venice from 24 to 29 September 2012.


The geoid, the Mean Sea Surface and the ocean Mean Dynamic Topography are key reference surfaces for using altimetric data. The quality of the altimetric sea level product (Sea Level anomaly, Absolute Dynamic topography) directly depends on the quality of these surfaces. Very significant improvements have been made in the last 20 years for the computation of these surfaces.


Regarding the altimetric Mean Sea Surface, the estimate of an accurate, high resolution product is getting more crucial with the growing number of altimeter satellites on non repetitive orbits as Cryosat-2, Jason-1 EOL, Envisat...Improvements are needed notably far from the past repetitive altimeter satellite tracks. This will be possible in the coming years by using data from new tracks (Envisat+, Cryosat-2, coming HY2) or reprocessed products from old and current missions. CryoSat-2 has demonstrated improved range precision relative to other Ku-band altimeters, and similar improvements in range precision may be expected from AltiKa. These data may be used to derive improved mean sea surfaces and improved estimates of marine gravity anomalies, from which improved estimates of bathymetry may be obtained.


Concerning the geoid, a number of new gravity field models have been made available based on the use of GOCE data. Although the mission is not finished, strong improvements are already visible at scales shorter than 200-300 km compared to previous GRACE geoid models.


The use of improved MSSs together with improved geoids will naturally result in a better knowledge of the ocean Mean Dynamic Topography, which is essential to reconstruct the absolute dynamic Topography, and therefore the ocean geostrophic currents, from altimetric Sea Level Anomalies.


In this session, we therefore encourage abstracts dealing with the computation of improved altimetric Mean Sea Surfaces, making use of reprocessed products and/or new missions, possibly on new tracks, as well as abstracts highlighting the impact of recent geoid models based on GOCE data (possibly in synergy with GRACE data) for altimetric use, in particular for the better estimation of the ocean Mean Dynamic Topography. Papers on improvements in the marine gravity field and derived bathymetry are also welcome. The abstract deadline is February 15, 2012. You can find more information at the symposium web site: (Abstract Submission) <>


Looking forward seeing you in Venice,


The scientific committee of the "Mean Surface & Marine Geoid, Bathymetry" session

Last reminder
Abstract deadline
Tenth International Conference on Permafrost
25-29 June 2012
Salekhard, Russia
Deadline: 10 February 2011

The International Conference on Permafrost is the premier event for
permafrost research, organized by the International Permafrost
Association every four years. The Tenth International Conference will
take place in Salekhard, located on the Arctic Circle on the east bank
of the Ob River, 25-29 June 2012.

The deadline for extended abstracts has been extended to the 10th of
February, 2012. Authors who submit an abstract will be eligible for an
oral presentation or a poster.
You can submit your extended abstract and read instructions at the
following address:

Registration to the conference will be possible until April 30, 2012 at
a reduced rate and until May 31, 2012 at full rate. Early registration
is strongly recommended to facilitate visa application.

150 young researchers who are first author on either an oral or a poster
presentation will receive a full stipend generously funded by the
Yamal-Nenets Autonomous District. The stipend will cover return travel
costs by charter flight from Moscow to Salekhard, registration fees,
student housing in Salekhard, a local field excursion during the
conference, meals and social events. The deadline for applications to
the young researcher stipend program is also the 10th of February 2011.
The application is done through the standard registration process on the

Regular registration will cover return travel costs by charter flight
from Moscow to Salekhard, conference fees, meals, social events and
housing in Salekhard, with the cost of the total package depending on
the level of accommodation selected. Discounts of 50 USD will be applied
to individual paying members of the IPA (register here:

Extended field trips will take place after the conference with the
return charter flight to Moscow taking place on July 5. The trips will
be offered at very advantageous rate.

information go to:

We look forward to seeing you at an exciting conference in Salekhard
next June!

Dear colleagues;

A gentle (and final!) reminder that abstracts for CGU session H2: Observations and Models in Canadian Glaciology are due 15 Febrary 2012.  The Canadian Geophysical Union Annual Meeting takes place from 5 - 8 June 2012 in Banff, AB, Canada.

Session Description:
Glaciers are sensitive indicators of climatic change. Recent evidence from western Canada and the Arctic reveals substantial retreat and downwasting over the last 30 years. This retreat bears directly on hydro-electric power generation, aquatic ecosystems and sea-level rise. The proposed session encourages submissions that (a) observe and model glacier mass balance; (b) use remote sensing techniques to document glacier change; (c) examine links between meteorological processes and glacier mass balance; and (d) assess the hydrologic and ecosystem impacts of glacier change.   We also welcome contributions that aim to model the fate of Canadian glaciers under future climate change scenarios.

Submission guidelines and details can be found here:

We look forward to seeing you in Banff!
