For online participation for the International Antarctic Ice Rises Workshop, we will be using the GoToMeeting Platform (www.gotomeeting.com). If you have not used this system before, we suggest logging on ~15 minutes before the start of the first day - a small plugin will need to be downloaded from the web and installed on your computer the first time you use it (after that you should not need to reinstall the plug in). You have the ability to test your audio to make sure we can hear you, etc. There is a chat box that you can use to ask questions, chat to other online participants, etc. You will be able to hear the presenter and see the slides - and we are hoping to have video of the presenter as well (that part will depend on the bandwidth of participants, etc).
If you would like to ask a question or provide a comment during the meeting, please us the chat box to alert the online moderator that you would like to speak so we can get that attention of the presenter. We will then give you the floor to ask your question to the room. Please be sure to mute your line (by clicking the microphone icon) when you are not speaking to reduce background noise.
If you have participated in an online meeting before, you know that there can sometimes be technical glitches and challenges to overcome. We will do our best to make sure everything goes smoothly, but if at anytime during the meeting you have suggestions on how we can improve sound quality, etc, please send Jenny Baeseman a text: +47 4821 8095.
We will also keep the online meeting going during the breakout sessions, so we hope you will be interested in participating in that as well. You can log in and out as many times during the meeting as you would like, so if you need to leave and want to join back in later, that is no problem.
To join the meeting, simply click on the link corresponding to the day and follow the instructions.

The workshop will be composed of scientific sessions and outreach/education sessions. The latter are organized by Association of Polar Early Career Scientists (APECS). The motivations and topics are indicative and not intended to be exclusive. In each session, following key note speech and one or two oral presentations, all attendees are invited to participate in interactive discussion to identify remaining open questions and approaches to solve these questions. This session will provide the feedback to help researchers place their work in an Earth Systems context.
We invite all participants to present their recent findings, research tools, and ongoing and near-future projects in the poster session; the posters are presented throughout the workshop and we reserve ample of poster viewing/discussion time during the lunch and coffee breaks.
1. Ice rise glaciology While the flow of ice rises is apparently quite simple, do more detailed observations show complexity. Is this expected or enigmatic? New understanding of the grounding line has yet to be applied to ice rises; what else is required in such modelling to fully interpret the field data? Alternatively, what field data are necessary to fully constrain the model?
2. Satellite remote sensing (thinning rates, velocities, scars, lineations)
How should we be focusing the analysis of the wealth of new satellite data to improve our understanding of ice rises? Where do the data need to be improved, and how long does the instrumental record need to answer the key questions?
3. Ice shelf and rumples
The complexities of ice-shelf flow arise from transiency in ice streams, the presence of ice rises and the distribution of sub-shelf melt. What parts of the ice shelf is sensitively affected by them and how? What do these complexities record, and what more is needed to understand how ice-rises interact mechanically with the large ice-sheets?
4. Interactions between ice rises and ocean/sea ice (effect of ice-rises on sub-shelf flow, distribution of melt/freeze-on relative to ice-rises)
How do ice-rises affect sub-shelf ocean circulation and the distribution of melt? Under what conditions can melt near the grounding lines of ice rises strongly affect the evolution of the ice rise?
5. Geology, geophysics and post-glacial rebound, origin of topographic highs
How long have the topographic highs responsible for ice-rises existed; are they erosional remnants or due to uplift? How might these features have evolved during the life of the West Antarctic Ice Sheet (WAIS)? What geophysics do we need to do solve this? Can we measure post-glacial rebound on ice-rises?
6. Palaeoclimate, including ice cores and ice-core-related modeling
What have we learnt about Antarctica and the surrounding oceans from existing cores; what information they do provide about ice-sheet palaeo-geometry and southern ocean sea ice?; what can other locations offer?
7. Surface mass balance, local climate
How are ice-rises expected to affect precipitation patterns locally and regionally; what can palaeo-precipitation patterns inferred from radar layers tell us about the operation of the climate system? How does this affect interpretations of an ice core from an ice rise?
Pick up Framsenteret. A trip by a 50 seats coach. We start with a short cityguiding of Tromsø. Then we bring you out of the city and over to the island of Kvaløya. On the trip we have several stops. Also some where we will walk a bit around in the nature.
During the trip we will have a stop at a local café for a dinner and coffee/cake. Of course it is local food. Meanwhile waiting for the meal you can have a look around the building where you find a local artist producing art from glass.
After the meal and drinking the coach will bring us to another spot trying to find The Northern Lights. It is a bit early in the season but if we are lucky we will have a short hour where we can study this fantastic show. After trying to spot The Northern Lights we will be back at the latest 0130.
The settlement in the area of Tromsø is about 9000 years old. We are located close to 70 degrees north. To survive up here people had to have the knowledge how to handle the long and dark winters and the short and cold summers.
We try to give you an answer for questions like: What kind of resources did people use to survive? What could you eat up here 2000 years ago? How can you use the natural resources to get an income?
We will focus on the landscape/nature. Try to teach you a little about “reading the landscape”. The first settlements and the rock carvings: Why do they settle just there and why did they do the rock carvings just there?,
What about the Vikings? Did they come so far north? What about farming so far north? What can you grow? How important is fishery? Is it still plenty of fish in the see?
“It looks like wilderness. But actually it is the garden for the local people!”
Clothing: We recommend you to use some solid shoes. You do not need hiking boots. Bring warm clothes like a good sweater, a good jacket and a hat. If it is raining we recommend a Gore Tex jacket or something similar.
