The M=6.2 EQ in Storfjorden near Svalbard 21 FEB 2008 raised considerable scientific interest and is the background for looking into the feasibility of placing two or three temporary seismometers on Edge- and Barents Island. This web page contains some technical considerations in this regard. More background information in SIOS Working Group 5: SOLID EARTH AND LARGE TIME-SCALE PROCESSES, Final Report, 30 September 2009.

Telemetry design specifications will of course influence power supply need. The main telemetry alternatives are, listed by rising power consumption:
The various communication systems suitable must also be compared and assessed.
A tiltable mast facilitates easy maintenance and construction.
The AWAKE project installed many weather stations on Svalbard. Here are some very informative photos extracted from presentation given by Mr Øyvind Nordli, Norw. Met. Office, at Progress Meeting held November 4-5th, 2010 in Oslo. We might contact Ø.N. and ask for mast manufacturer details, and their experience so far with these mast designs. They look very robust, but that impression must be confirmed by some knowledgeable person.
The project has been extended, here is information about AWAKE-2 project.
Any constructions on East Svalbard might be visited by polar bears. Equipment must be dimensioned to safely withstand a leaning bear, as indicated below - at least!
We might consider installing additional sensor systems.
Perhaps these guys can give some advise: http://www.projects.science.uu.nl/iceclimate/aws/technicals.php
Designing instrumentation for remote and exposed locations on Svalbard is a challenging task. We have to seek advise from other institutions that have experience in this area. Here is a brief overview of existing instrumentation systems installed in remote parts of Svalbard, and the institutions that operate them. In addition, if our instrumentation is co-located with that of others, transport and logistics benefits are obvious.

The station is an Onset data logger H21-001 and Onset sensors (see http://www.onsetcomp.com). The station records data every 30 minutes." (quote from here.)
