Mathematics on Ice

Welcome to the Mathematics on Ice Forum.  We meet once a month to discuss mathematical aspects of ice dynamics and bring together the community in an informal online atmosphere.

To sign up to the distribution list and receive Zoom coordinates, please fill in this form: 

See below for the upcoming schedule.  The forum is usually 4:00pm to 5:30pm UK Time, though some sessions are at a different time to accommodate people in far-off timezones.  In each meeting there are two presentations and time for discussions and ice-breaking in small sub-groups.  The typical format is:

4:00 - 4:25 First talk + questions
4:25 - 4:35 Breakout discussion / ice-breaking
4.35 - 5:00 Second talk + questions
5:00 - 5:10 Breakout discussions / ice-breaking
5:10 - 5:30 Summary questions / discussion

If you can't make it for all the time, feel free to attend while you can.

The format is intended to stem from your contributions – give a talk, join the discussions, invite further participants or send us your ideas for future meetings!  Everyone is very welcome and encouraged to contribute.  We would like to encourage in particular PhD students to present their research.

Maths on Ice Code of Practice

All Maths on Ice participants are expected to aspire and adhere to the following standards of behaviour:

  1. Treat everyone with respect.
  2. Respect your fellow participants by using good practices for intercultural collaborations.
  3. Be mindful of your surroundings and of your fellow participants.
  4. Provide your true professional identity, affiliation, and, where appropriate, contact information, at registration, and during attendance and participatory sessions, as required.
  5. Do not take screenshots, download the sessions chat, record the sessions, or share them on social media unless you obtained the permissions by the speakers.
  6. Be Accountable: When we as organizers or participants fail to meet these guidelines, we should work together to identify problems and adjust policy and practice together. Anyone not meeting expected, collaborative, respectful behaviour can be immediately removed from the online meeting and may be banned from future seminars, depending on the specifics of the unwelcomed disruptive behaviour.

Examples of unacceptable behaviour

  • Promoting or participating in harassment, bullying, discrimination, or intimidation during the meeting and/or on social media.
  • Verbal, written, or other forms of abuse of any attendee. Examples of abuse include, but are not limited to, verbal comments related to gender, sexual orientation, disability, physical appearance, body size, race, religion, national origin, or use of inappropriate images.
  • Disruption or disallowing of participation by others.
  • Criminal offenses.
  • Verbal abuse.
  • Use of social or mainstream media to target individual actions of participants in a way that could harm their privacy or professional status or open them to slander or libel.
  • Knowingly violating copyright or copying presenter information without obtaining permission.
