Title: When can we expect the Greenland glacier to melt?

Room: VR-II,V-258
Time: Tuesday 27nd August, 11:00hrs

Abstract:

It was suggested by Rose (2005) that because of the migratory and responsive nature of the capelin, a small pelagic fish that is key to the ecology and fisheries of the North Atlantic, it can be viewed as the “canary in the coalmine” to detect signals of environmental changes in the Arctic Ocean. In this talk we will combine analysis of data and extensive simulations of the migrations of the capelin and its physiology to analyze the changes in the ocean environment taking place over the last half-century. The environmental data for the last thirty year is obtained from a database called Copernicus, constructed by the European Union. Our goals will be to understand and predict the migrations of the capelin and its interactions with the ocean environment. We will explain how these have changed over time and how they are likely to change in the future. Then we will explain how our simulations can be compared with data, with the aim of finding out the rate of the temperature changes in the Arctic Ocean and when thresholds for major disruptions in Arctic environments are likely to be reached. The recent changes in the spawning routes of the capelin lead to a startling prediction.

The Icelandic Mathematical Society will hold a meeting on Thursday April 23 at 16:45 in the lecture room V-158 in the building of the School of Engineering and Natural Sciences, University of Iceland, at Hjardarhagi.

We follow our traditions by starting the meeting with a cup of coffee or tea, but at 17:15 Finnur Larusson, University of Adelaide, Australia, will give a lecture:

Flexibility and rigidity in holomorphic geometry
An international conference in complex analysis and complex geometry will be held at the University of Iceland April 24-26. The goal of this talk is to give a general audience some insight into new research in this area, with a focus on two fundamental themes in complex geometry: flexibility and rigidity. The talk should be accessible to anyone who has done an undergraduate course in complex analysis. The talk will be given in English.
