Scientific Cross-Cutting Groups


The number of scientists working on MOSAiC data is permanently increasing. Collaboration and cooperation is typically "science question based" resulting in  cross-cutting and interdisciplinary groups of scientists who are working on specific topics. New topics and corresponding cross-cutting groups are welcome but also new members to existing groups. The group communication is realized by mail lists managed by the group leaders of the individual groups. Once a cross-cutting group and a corresponding mail list is established, interested researches can self-(un)subscribe to the mail lists according to the following description. Established cross-cutting groups are listed below.

Subscription / Unsubscription

Interested people can subscribe and un-subscribe themselves to the working group mail lists by writing a message to from the address they want to subscribe to the list/un-subscribe from the list. 

In the subject line of your message, type in: subscribe nameofthelist FIRSTNAME LASTNAME (replace 'nameofthelist' by the name of the list you want to subscribe to and indicate your own first name and last name; leave the message body blank). Individual nameofthelist attribute of established mail lists is given in the table below.

Creating a new cross-cutting group & mail list

If you would like to establish a new cross-cutting group or to create a new mail list please write us via the contact form the group name (max. 2 words), group leader (first name, last name, affiliation) and a description of the group (<150 words). MOSAiC office will create a mail list with standard settings and publish these 3 information here on the website, so that interested people can find it. Communication via the mail list is managed by the group leader.




Leader: Bonnie Light

Mail list (nameofthelist): 


Optics working group includes individuals who either contributed to the Optics measurement program or are interested in using optical data from MOSAiC. These individuals are from different MOSAiC Teams (ICE, ECO, BGC, ATMO). 

RISE  (responsible science initiative)

(former Sustainability Group) 

Leader: Amy Macfarlane

Mail list (nameofthelist): 


RISE was born from a group of participants in the 2019-2020 MOSAiC research expedition to consider how to minimize the environmental impacts of their research while maximizing the scientific impact. The scientific community widely agrees that polar research is essential for understanding and protecting sensitive environments, but considering and weighing the consequences has been largely undiscussed. We are currently taking the initial step to reduce the environmental impact of expeditions by conducting an environmental impact assessment of the MOSAIC expedition. In parallel to this, we have i) written opinion article directed towards funding bodies on the steps they can take to reduce expedition impacts and ii) created a RISE-APECS project group to provide opportunities to early career researchers to influence and contribute to the current shift in fieldwork sustainability. The aim of this RISE-MOSAiC group is to create a network of environmentally responsible fieldwork researchers and work towards providing education and awareness to the scientific community.

Meltwater Layer 

Leader: Madison M. Smith

Mail list (nameofthelist):


Working group on meltwater layers and near-surface stratification observed during the MOSAiC expedition. Thin (< 1 m) layers of relatively fresh (salinity < 10) meltwater were observed during Legs 4 and 5 under-ice, in leads, and in melt ponds. Group activities include quarterly meetings, coordination of interdisciplinary manuscripts, networking and planning for future activity.

Heat Budget

Leader: Linda Thielke

Mail list (nameofthelist):


The winter heat budget group includes scientists working on the physics of the ocean, sea ice and snow, and atmosphere. We work with in-situ, airborne, and satellite-borne observations and collaborate with experts from the modeling community. This group aims to calculate the “full” winter heat budget from MOSAiC data. Our discussions are about temporal and spatial variability, comparison of different approaches, quantifying residuals and uncertainties, and determining how the results from the observations can be included in models. Are you interested in contributing to the understanding of the winter heat budget? Please join our email list and stay updated.

Single Column Modeling

Leader: David Clemens-Sewall

Mail list (nameofthelist):


Single column modeling of MOSAiC provides an opportunity to compare model physics with observations. These models require merged datasets from observations for their initial conditions, forcing, and to validate their output. MOSAiC provides a wealth of observations for these merged datasets. However, if different model simulations use different initial conditions, forcing, and validation datasets it will be difficult to disentangle whether differing results arise from different model physics or different datasets used to drive the models. The purpose of this working group is to address this problem by developing shared datasets for driving single column models. These merged datasets will be formatted in NetCDF consistent with the MDF standards ( and shared within the working group. Finalized datasets will be published in a data repository with a doi.

Ice Dynamics

Leader: Jennifer Hutchings

Mail list (nameofthelist):


The ice dynamics group formed out of the snow and ice teams “ice dynamics” task. Members of the group include those who managed data collection during that task as well as those who implement methods to observe sea ice kinematics in the wider region around the MOSAiC central observations by tracking buoys in the distributed network or from remote sensing. The group has expanded to include all who are working with the data collected on research projects investigating sea ice dynamics and mechanics at MOSAiC. The group includes members with remote sensing, modelling and observational focus. While our goals are on improving understanding of sea ice dynamics, we do have interests in serving the wider MOSAiC community with products and knowledge on sea ice deformation, lead opening and ridging, floe size and the mechanical redistribution of sea ice thickness to allow tracking of the evolution of the icescape. 

Early Career Researchers

(<5 years of receiving the PhD)

Leader: David Clemens-Sewall (support Alexander Schulz) 

Mail list (nameofthelist):


The mail list allows us to reach out directly to ECRs in and around MOSAiC.
