THANKS FOR A GREAT CONFERENCE!

 

The Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) was an international, interdisciplinary Arctic scientific expedition that drifted across the central Arctic from autumn 2019 to autumn 2020. The 2nd International MOSAiC Science Conference will be held 13-17 February 2023 at the University of Colorado in Boulder, Colorado, USA. Conference objectives are to foster cross-cutting scientific analysis, address issues of spatiotemporal scaling of information, and promote advancement of modeling and predictive capabilities. The weeklong conference will offer a mix of plenary sessions with visionary keynote presentations, focused breakout sessions on a variety of thematic topics, poster sessions, flex-time for ad hoc meetings, a planetarium film viewing, and much more. The conference will build upon the 1st International MOSAiC Science Conference from April 2022. Since MOSAiC observational data are expected to be publicly available by the start of 2023, this conference is an opportunity to expand the MOSAiC science community through the use of these data. Conference participation is open to all, with the expectation that all contributions are focused on MOSAiC-related research.

1: MOSAiC Observations in the Context of Historical Data

Conveners: Myriel Vredenborg, Sinhué Torres-Valdés, John Cassano, Luisa von Albedyll

This session aims on setting the base for the interpretation of all the different kinds of MOSAiC observations and is addressed to all MOSAiC Teams. The following questions are addressed: Are the MOSAiC observations representative for the changes observed in the past years/decade? What was completely new/exceptional? Did we sample the ‘new’ or the ‘old’ Arctic? How do MOSAiC observations in general compare to historical data and what does it imply for the interpretation of our observations? What limitations or opportunities arise from these findings?

2: Process Modeling at Multiple Scales

Conveners: Amy Solomon, Roel Neggers, Niklas Schnierstein, Gijs de Boer

MOSAiC provides a unique opportunity to model key Arctic system processes using a variety of modeling tools, including: Regional coupled and uncoupled models, nested meso-scale models, large-eddy simulations, single-column models, Lagrangian approaches, and more. Importantly, by leveraging these different types of models towards common foci, enhanced progress can be made in the representation of uncertain fast processes related to mixed-phase clouds, surface heat fluxes, the influence of leads, atmospheric boundary layer structure, atmosphere-ice-ocean interactions, and ocean mixing, as well as large-scale processes related to Arctic Amplification and climate system change. This session welcomes presentations using any of these high- to intermediate-resolution model approaches. Building on the session's presentations, a discussion will aim to identify shared scientific goals and explore the collective development of targeted case studies for model analysis and assessment.

3: Numerical Model Improvements in the Next Decade

Conveners: Klaus Dethloff, Lorenzo Zampieri, Thomas Rackow

This session encourages submissions that describe the plans of leading weather forecast and climate modeling centers for improved numerical forecasts and climate predictions with state-of-the-art coupled models in the Arctic and beyond in the coming decade. Topics of interest include model assessment and forecast skills for targeted observation periods, the parameterization of coupled processes at the interface between ocean, sea ice, and atmosphere, including improved multi-category sea ice and snow models, and observational data assimilation of the coupled Arctic system. We welcome presentations on the current and next generation of weather and climate prediction systems in Arctic, with a particular focus on control of complexity, enhanced resolution, and resolved meso-scale physics. This overview will build the foundation to develop new synergies between MOSAiC observations and the modeling community for the exploitation of the unique MOSAiC datasets in future model development plans.

4: Bridging Temporal and Spatial Scales in Observations and Models

Conveners: Marcel Nicolaus, Hannah Niehaus

This session will present and discuss ideas, approaches, concepts and first results of studies that bridge scales. Most observations and models have a very specific spatial and temporal coverage and discretization. Observations are sparse and only exist under specific conditions. Depending on the scientific objectives, upscaling or downscaling is needed to merge data sets from different groups and methodologies. Also issues of different reference / coordinate systems need to be overcome and will be discussed here.

5: Aggregated Datasets and Methods for Model Evaluation

Conveners:  Marylou Athanase, Michael Gallagher

The evaluation and improvement of climate models’ skills in representing the Arctic system is one prominent goal of MOSAiC. A wealth of in-situ measurements was collected during the MOSAiC drift, and comparing these observations to model output is essential for assessing the quality of simulations. This session aims to provide a forum to discuss products and methods for model evaluation using MOSAiC observations. We invite contributions focusing on but not limited to the advertisement of datasets, and discussion around the preparation of data products, including Merged Observatory Data Files (MODFs) / Merged Model Data Files (MMDFs). Contributions can additionally include multi- and cross-model evaluations focused on the MOSAiC drift. Finally, studies investigating approaches aiming to optimize the use of short-term observational campaigns like MOSAiC, such as machine learning applications or novel methodologies for model evaluation, are particularly welcome.

6: From the Ice Floe to Space – Remote Sensing and MOSAiC

Conveners: Philip Rostosky, Malin Johansson, Polona Itkin

This session aims to discuss remote sensing observations collected for MOSAiC and their applications across all scales. Besides local and regional data analysis from the remote sensing site and airborne measurements, also studies using the MOSAiC observations to evaluate and improve large scale and long-term remote sensing datasets are invited (e.g., climate data records, ice types/topography/thickness, leads and ice concentration, snow and melt pond properties). Contributions where remote sensing data is used in connection to other disciplines, e.g., lead distribution for light transmission into the ocean and impact on ecology, or ice types and thin ice to evaluate energy and gas fluxes, are welcome. Topics for contributions include cal/val activities, novel algorithm development, mission advising (e.g. CIMR, CRISTAL, ROSE-L etc.), and process studies.

7: Arctic Atmosphere-Sea Ice-Ocean Coupling and Feedbacks, including Biophysical

Conveners: Ola Persson, Wieslaw Maslowski, Daniel Watkins

One of the main goals of the MOSAiC project has been to collect observations across the key components of the Arctic System to advance understanding, modeling, and prediction of their coupling and feedbacks under a warming climate and declining sea ice cover. Various challenges exist for using these measurements, including devising methods for deducing interdisciplinary linkages or coupling between the disciplinary observations, and upscaling of collected data on individual processes and their impacts to climate-model ‘grid-cells’ and the basin-scale. Hence, extracting evidence of coupling and feedback processes from the observations is critical, as is the endeavor to realistically represent these processes, interactions, and feedbacks in Earth system models across a range of spatiotemporal scales. In this session, contributions are invited that focus on various disciplinary processes, and their coupling across the surface boundary layer interfaces, including across the bio-physical domain. Contributions are welcome from MOSAiC observational studies and from model analyses on various time and spatial scales. Studies on feedback processes involving the atmosphere, ice, ocean and bio-geochemical domains are of particular interest. Finally, the organizers invite presentations that will encourage active discussion of interdisciplinary processes and their potential role in coupling and feedbacks.

9: Evolution and Interaction of Sea Ice and Snow Properties Across Time and Space

Conveners: Anne Sledd, Marc Oggier, Ruzica Dadic, Allison Fong, Martin Schneebeli, Mats Granskog, Don Perovich, Amy Macfarlane

The MOSAiC ice, snow, and ecosystem observations highlight how Arctic sea ice and its processes are incredibly complex vertically, spatially, and temporally. Yet accurate model simulations of many associated processes are lacking. Our challenge is to harness these new observations to better understand the system's complexity, assess model quality, develop sub-grid-scale parameterizations, and thereby improve model predictive skill related to the representation of ice, snow, their ecosystems, and related processes. This session invites submissions that shed new light on how interactions within and across the sea ice impact local and regional processes that span a variety of space and time scales. We specifically invite observational and/or modeling contributions on snow and ice physics, chemistry, biogeochemistry, ecosystems, cross-cutting interactions, and more.

11: Vertical and Lateral Transport in the Ocean

Conveners: Kirstin Schulz, Zoe Koenig, Sinhué Torres-Valdés

Physical transport processes in the ocean, such as vertical turbulent mixing and lateral advection by eddies or mean currents, distribute tracers and set boundary conditions for other subsystems like sea ice, biogeochemistry and ecology. Despite the large amount of available oceanic data, the interpretation of these data sets to quantify transport pathways is not always straightforward, and is further complicated by the fact that MOSAiC was an ice drift experiment, where spatial and temporal trends in the ocean cannot be easily separated. In this session, we would like to discuss oceanic transport and dynamics, and how they affect tracer distribution of heat, nutrients, particles, oxygen, plankton, detritus, and more. Individual observations of any of these tracers with their different sources and sinks will help us to better quantify physical transport pathways, and separate regional and temporal trends along the drift path, which in turn benefits the interpretation of the spatio-temporal distribution of other tracers. We invite contributions from any discipline that are in some way related to oceanic transport acting on any temporal or spatial scale.

12: Storms and Airmass Intrusions to the Arctic during MOSAiC

Convener: Sandro Dahlke, Daniel Watkins, Chris Cox, Julia Schmale, Gunilla Svensson

MOSAiC was affected by a number of cyclones and air masses, many having extra-polar origins. These synoptic events are characterized by distinct, high-amplitude, short-term variations in the atmosphere, and may be associated with distant sources of moisture transported poleward.  Such transport has been linked to Arctic amplification through changes in sea ice concentration caused by intense warming events during springtime. The impacts and mechanisms of these events span a range of spatial scales – ranging from local modulations of the chemical, cloud, precipitation, boundary layer, and thermodynamics structure to spatially widespread impacts on the sea ice drift, deformation, surface albedo, sea-ice properties, radiation, humidity anomalies, ocean circulation, stratification, and stratospheric dynamics. This session welcomes contributions focused on impacts, feedbacks, variability, and processes pertaining to synoptic events from both observational and modeling perspectives.

14: Atmospheric Boundary Layer: Structure and Processes

Conveners: Gina Jozef, Ola Persson

The Arctic atmospheric boundary layer (ABL) is the interface between the free troposphere and the sea-ice. As such, its structures and processes are key for the transport and mixing of heat, momentum, moisture, aerosols, and gases in both directions between the sea ice and the free troposphere, and characterizes the unique Arctic atmospheric near-surface environment. This session on the atmospheric boundary layer invites presentations describing the ABL structure observed during MOSAiC, processes that modulate this structure (e.g., cloud interactions, synoptic conditions), key mixing processes, and ABL interactions with the free troposphere and different surface types. Presentations showing the effects of ABL processes on other observed features, such as the evolution of chemical or gas constituents, surface energy budget, etc., are welcome.

16: Dynamical and Chemical Controls on Arctic Atmospheric Composition and Aerosols

Conveners: Laurens Ganzeveld, Hélène Angot, Sjoerd Barton, Julia Schmale

The MOSAiC campaign has yielded a full seasonal cycle of observations on atmospheric composition in the Arctic including boundary layer (BL) and free tropospheric aerosol, reactive compound concentrations and climate-active trace gas surface fluxes. Given the crucial role of BL dynamics as well as long-range transport of aerosols and trace gases, analysis of these observations requires careful consideration of local- versus large-scale contributions to observed concentrations and fluxes. This can be inferred from observations on BL dynamics, trajectory analysis and model experiments, e.g., using Large Eddy Simulation, 1-D or 3-D models. We invite presentations that aim at interpretation of MOSAiC’s atmospheric composition observations, possibly supported by modelling experiments and trajectory analysis to assess the role of BL dynamics and long-range transport in explaining these observations.

19: Carbon Transformations and Fluxes, and their Dependency on Biodiversity

Conveners: Hauke Flores, Barbara Niehoff, Pauline Snoeijs-Leijonmalm, Allison Fong

MOSAiC offered the opportunity to address many open questions about the high-Arctic ecosystem, including those focusing on patterns of biodiversity, abundance of organisms from microbes to large fish and squid, and the quantities of carbon and nitrogen channeled through the food web. We invite submissions which highlight key processes with controls on pools of carbon quantified during MOSAiC and beyond that will enable us to map fluxes of carbon through the Arctic ecosystem, including transformations of carbon via chemical and biological activities from microbes to macrofauna. We also encourage contributions sharing results on genomic, organismic, and functional biodiversity from genes to whole metazoans, its related physiology, community structure, trophic fluxes, primary and secondary productivity, and the role of biodiversity for elemental cycling and other ecosystem functions. If carbon is not your primary currency, we also welcome submissions on other elements and compounds to complement and foster discussions on our understanding of material transformations and fluxes.

20: Optical Properties and Processes in the Arctic Air-Ice-Ocean-Eco System

Conveners: Bonnie Light, Radiance Calmer, Patrick Taylor, Hanna Niehaus

The optical properties of the atmosphere, snow, sea ice, ocean, and associated biota strongly modulate the partitioning of shortwave solar radiation in the Arctic system. The albedo and transmittance of the MOSAiC ice cover were measured to help constrain radiative energy budgets between air, ice, and ocean. These were characterized from sun up through freeze-up. Additionally, novel techniques for measuring light attenuation within the ice and ocean were used to collect data on the physics of radiative transport. When integrated, these measurements form a basis for quantifying the surface radiative heat budget, improving interpretation of remotely sensed data, enhancing the representation of spatial and temporal complexity of radiation in regional and climate models, and improving our understanding of the fundamental physics of light transport by an ice cover known to vary both seasonally and interannually. Contributions related to the measurement and modeling of the optical properties of the various elements of the Arctic system are solicited. We are particularly interested in contributions that (1) help knit together individual components of the surface radiative heat budget during polar day, (2) scale-up optical point measurements for use with larger scale observations, and (3) advance the state of optical property modeling in the Arctic.

23: Interdisciplinary Processes across Strong Physical Gradients

Convenors: Emelia Chamberlain, Jessie Creamean, Maddie Smith

The goal of this session is to highlight interdisciplinary work that advances our understanding of coupled processes in the Central Arctic. This session combines interdisciplinary topics that span strong environmental gradients and physical shifts which were observed during MOSAiC. These topics include: (1) the seasonal transition from late spring (polar night) to early summer (polar day); (2) strong stratification of thin meltwater layers during the melt season; and (3) episodic or fine-scale events at habitat interfaces including light variability, sea ice dynamics, melt, freeze, and storm activity. Strong temporal and spatial gradients drive unique responses in atmospheric, oceanic, sea ice, and ecological processes. This session aims to boost synergies across projects, institutions, and disciplines, which will help the MOSAiC and broader science community accelerate understanding of how fine-scale processes can help explain the trends within the MOSAiC time series.

Early career researchers (ECR) are important contributors to, and participants in, MOSAiC science and their presence at the MOSAiC Conference is essential. The Conference will have multiple ways to support and engage ECRs.  

Early Career Researcher Session and Evening Activity

There will be a dedicated session and activities for Early Career Researchers on Tuesday, 14 February starting at 18:30. The ECR organizers are anonymously soliciting ideas for the ECR session in this form. We welcome anyone's input!

Talking with Journalists about Science

Are you interested in communicating more with the media? Do you think you will interact more with journalists in the future?  On Thursday, 16 February at 18:30-19:30 there will be a discussion for ECR with a few journalists from a special journalist program at the University of Colorado. It will touch on how journalists use scientific information and how scientists and journalists can work together to better communicate information to the public.   

Student Presentation Awards

To support best practices in giving presentations and making posters, and to provide valuable feedback to our student participants, the Conference will have a best student presentation competition. Awards of recognition will be given to the best oral and best poster presentation. The competition is open to all current students. To sign up for the competition, please check the appropriate box on the registration form when registering for the Conference.  And for those who are non-students: We would appreciate you volunteering to serve as judges, which can also be done during the registration process.  

Early Career Travel Support Program

To support and enable active ECR participation in the conference there is an ECR travel support program. The program is open to researchers who are students or within 7 years of receiving their PhD. Note: this 7 year definition for ECR is an extension beyond the typical 5 year definition to help accommodate career challenges related to COVID and other issues in the past few years. Awards for this competitive program will range from a fixed travel stipend to full travel support. Award recipients and amounts will be decided by a small committee, based on the applicant's contributions to MOSAiC science, contributions to the MOSAiC conference (i.e., session convening, flex time sessions, etc), and need for support (or lack of other support). The application due date for this program has passed, such that no further applications will be accepted.

Participation in the conference is possible both "in-person" and "virtually", and requires registration. All registered participants will receive virtual connection information via email in the week prior to the conference.

IN-PERSON PARTICIPATION:  Registration fee = $550.  Deadline: January 11, 2023 (23:59 MTN)

Includes all Plenary, Parallel, and Poster sessions, and Flex time discussions. Also includes the Welcome Reception and Fiske Planetarium Show, Conference Banquet, and Coffee Breaks.

VIRTUAL PARTICIPATION:  Registration fee = $350.  Deadline: February 12, 2023 (23:59 MTN)

Includes virtual access to high-quality, real-time Plenary and Parallel sessions. Live questions, answers, and discussions will be available to support remote participation.
