Central IT Services
IT services are provided at MPI-M by the Central IT Services (CIS) group.
The most important services of the Central IT Services are:
- Procurement, setup and management of IT hardware and software for both users (laptops, PCs) and infrastructure (servers, networks, etc.)
- Central user administration
- Provision of an efficient network (LAN, WLAN)
- Central IT help desk as a contact point for all IT-related issues
- Provision of services to support daily work (e.g. version management, project management, websites, etc.)
- Ensuring secure IT operations (failover, backup, IT security)
Detailed documentation on the IT Group’s offerings can be found in the Wiki of the institute.
An account (username and password) is required to use most IT services. Usually, an account will be created for you as soon as you have a contract with MPI-M. If you are a guest at MPI-M and need an account, your group leader at MPI can request an account for you. Further details are described in the institutes Wiki.
If you have any questions or problems using the IT systems at MPI-M, please contact the IT help desk.
Please note that questions regarding the DKRZ systems (e.g. Levante or data archive) will be answered by the DKRZ user support.

A new mechanism for synchronising Heinrich events with Dansgaard-Oeschger cycles
Using simulations with a coupled ice sheet-solid earth model that are forced with a synthetic Dansgaard-Oescher cycle, Schannwell et al. present a Heinrich event mechanism that overcomes previous shortcomings and reproduces all main characteristics of Heinrich events from the paleo record under a wide range of forcing scenarios. In their mechanism, internal ice-sheet instabilities are the underlying cause for triggering Heinrich events. The timing of these events, however, can be locked into the cooling phase of the Dansgaard-Oeschger cycle through an atmospheric perturbation (e.g., snowfall and surface temperature) that is induced by the Dansgaard-Oeschger cycle itself. The atmospheric mechanism permits a pan-ice sheet response and allows for the occurrence of synchronous Heinrich events from two ice streams of the Laurentide Ice Sheet – a characteristic from the paleo-record that previous theories revolving around the ocean as the key driver have so far failed to explain.
A distinct advantage of the atmosphere-driven mechanism is that it is applicable to both ice streams terminating in the ocean as well as ice streams terminating on land. Therefore, the mechanism could provide insights not only on episodic glacier accelerations in the past, such as Heinrich events, but also on modern-day episodic accelerations observed from mountain glaciers and ice streams draining the Greenland and Antarctic ice sheets.
