The first community workshop and science planning meeting for the Hercules Dome ice core project will take place on May 10-11, 2021, using a virtual platform. This is both a planning meeting and an open science meeting, which will provide an opportunity to hear about some of the latest Antarctic ice core research, and to begin to develop new collaborations.

The Hercules Dome project is a major investment by the U.S. National Science Foundation (NSF), and represents a community platform for research, rather like an oceanographic cruise or a spacecraft mission. Hercules Dome follows in the long tradition of deep ice core projects supported by the NSF, including the GISP2 project in Greenland, the WAIS Divide project in West Antarctica, and the recently-completed South Pole (SPICEcore) project, all of which have led to substantial scientific advances.

Drilling at Hercules Dome is not expected to begin until 2024, at the earliest. This means that there is time to develop novel ideas, and to find ways to get involved in the project, whether through measurements on the ice core, modeling related to the ice and climate dynamics, meteorological observations in the field, innovative community engagement and education work, or other ideas.

The community workshop and science planning meeting will include a small number of invited speakers and substantial opportunities for participants to present their ideas and to network with others involved in Antarctic glaciological research, including, but not limited to, ice core science. Those working on the communication of polar science are also strongly encouraged to attend.

In preparation for the meeting, the Hercules Dome lead team will be hosting two informational webinars on March 23 at 1:00 p.m. and March 31 at 9.00 a.m. (both Pacific time) that will include Q&A sessions. The goal of these webinars is to provide more background on the project and answer questions that will enable interested participants to contribute more fully to the meeting in May. The webinars will have the same content, but will provide two different opportunities for people to attend. To register for one of the webinars, use one of the following links:

  • March 23 webinar (1:00 pm Pacific) registration is now closed
  • March 31 webinar (9:00 am Pacific) registration is now closed


On April 15 at 5:00 pm London time (12:00 pm Eastern, 9:00 am Pacific), we will have a special webinar lecture by Professor Eric Wolff of Cambridge University entitled “New frontiers in Antarctic ice core research”.

  • April 15 special webinar lecture (5:00 pm London time; 12:00 pm Eastern; 9:00 am Pacific) registration is now closed
