### Overview This dataset contains simulated significant wave height data generated from the WaveWatch III model run from 2020 up to 2070. It was produced to predict future environmental hazards threatening maritime navigation within the Arctic. Four unique simulations were produced using different Coupled Model Intercomparison Project Phase 6 (CMIP6) climate models' wind and sea ice projections along the shared socioeconomic pathways 5-8.5 (SSP5-8.5) future emissions scenario. The climate models used include: CNRM-CM6-1-HR, EC-Earth3, MPI-ESM1-2-HR, and MRI-ESM2-0. For each climate model, data is organized into yearly files written to NetCDF format. The data is contained on a spatially-varying unstructured triangular mesh which spans from 50° North (N) to 89.9°N and 180° West (W) to 180° East (E). The 'hs' variable presents the significant wave height (highest one thirds of wave heights) to occur for each node during the simulation in 6 hour intervals. ### Access Data files can be accessed via: [https://arcticdata.io/data/10.18739/A2ST7DZ74/](https://arcticdata.io/data/10.18739/A2ST7DZ74/)

The High-resolution (6 km) Ice-Ocean Modeling and Assimilation System (HIOMAS), 2010-2069
The High-resolution (6 kilometer (km)) Ice-Ocean Modeling and Assimilation System (HIOMAS) is used to simulate the evolution of sea ice for the Arctic Ocean and adjacent areas, including the Barents Sea, Norwegian Sea, Greenland Sea, Baffin Bay, and waters along Northwest Passage, over the period 2010 to 2069. The hindcast and future forcing over the period is from one of the Coupled Model Intercomparison Project Phase 6 (CMIP6) models, the CNRM-CM6-1-HR global climate model (GCM) run at the National Center for Meteorological Research, Météo-France and CNRS Laboratory (CNRM). Monthly mean sea ice thickness (meters (m)) is provided over 2010 to 2069 in NETCDF file format, with model grid information such as latitudes and longitudes of model grid cells included. I have archived future projection of monthly mean sea ice thickness files over 2010 to 2069 in https://pscfiles.apl.uw.edu/zhang/HIOMAS_6km/. The files are in netcdf format, which are created by running HIOMAS using the future projection forcing of the CNRM-CM6-1-HR GCM run conducted at the National Center for Meteorological Research, Météo-France and CNRS Laboratory (CNRM). Martin interpolated the forcing onto the new, expanded HIOMAS grid. There is a readme.txt file.

This dataset includes annual, gridded Arctic sea ice seasonal transition metrics (dates and periods) for fifteen Coupled Model Intercomparison Project version 6 (CMIP6) models and the Community Earth System Model version 1.1 (CESM1.1) Large Ensemble (CESM LE) (Kay, et al., 2015). Seasonal transition dates include melt onset, opening, break-up, freeze onset, freeze-up and closing. Seasonal transition periods include the melt period, the seasonal loss-of-ice period, the freeze period, the seasonal gain-of-ice period, the melt season, the open water period and the outer ice-free period. Data are provided for one ensemble member of the following models: Australian Community Climate and Earth System Simulator CM2 (ACCESS-CM2), Beijing Climate Center Climate System Model 2 MR (BCC-CSM2-MR), Beijing Climate Center Earth System Model 1 (BCC-ESM1), Community Earth System Model 2 (CESM2), Community Earth System Model 2 FV2 (CESM2-FV2), Community Earth System Model 2 Whole Atmosphere Community Climate Model (CESM2-WACCM), Community Earth System Model 2 Whole Atmosphere Community Climate Model FV2 (CESM2-WACCM-FV2), Centre National de Recherches Météorologiques ESM 2-1 (CNRM-ESM2-1), Centre National de Recherches Météorologiques CM 6-1 (CNRM-CM6-1), EC-Earth3, Meteorological Research Institute Earth System Model 2-0 (MRI-ESM2-0), Norwegian Earth System Model 2 LM (NorESM2-LM) and Norwegian Earth System Model 2 MM (NorESM2-MM). Data are provided for 40 members of the Community Earth System Model Large Ensemble (CESM LE), 35 members of Canadian Earth System Model 5 (CanESM5) and 30 members of Institut Pierre Simon Laplace CM6A LR (IPSL-CM6A-LR). The data is stored in netcdf format, and includes metadata in the netcdf files. The raw CMIP6 and CESM LE model output that these transition metrics are calculated from are publicly available at https://esgf-node.llnl.gov/projects/cmip6/ and https://www.earthsystemgrid.org/ respectively. This dataset was created to evaluate climate model projections of Arctic sea ice using seasonal transition metrics in the context of both observations and internal variability. It is used in the article Smith, Jahn, Wang (2020), Seasonal transition dates can reveal biases in Arctic sea ice simulations, The Cryosphere, in press. The discussion paper with a link to the final paper can be found at https://doi.org/10.5194/tc-2020-81. This work was conducted at the University of Colorado Boulder from 2019-2020.more » « less

Abstract Observations show predictive skill of the minimum sea ice extent (Min SIE) from late winter anomalous offshore ice drift along the Eurasian coastline, leading to local ice thickness anomalies at the onset of the melt season—a signal then amplified by the ice–albedo feedback. We assess whether the observed seasonal predictability of September sea ice extent (Sept SIE) from Fram Strait Ice Area Export (FSIAE; a proxy for Eurasian coastal divergence) is present in global climate model (GCM) large ensembles, namely the CESM2-LE, GISS-E2.1-G, FLOR-LE, CNRM-CM6-1, and CanESM5. All models show distinct periods where winter FSIAE anomalies are negatively correlated with the May sea ice thickness (May SIT) anomalies along the Eurasian coastline, and the following Sept Arctic SIE, as in observations. Counterintuitively, several models show occasional periods where winter FSIAE anomalies are positively correlated with the following Sept SIE anomalies when the mean ice thickness is large, or late in the simulation when the sea ice is thin, and/or when internal variability increases. More important, periods with weak correlation between winter FSIAE and the following Sept SIE dominate, suggesting that summer melt processes generally dominate over late-winter preconditioning and May SIT anomalies. In general, we find that the coupling between the winter FSIAE and ice thickness anomalies along the Eurasian coastline at the onset of the melt season is a ubiquitous feature of GCMs and that the relationship with the following Sept SIE is dependent on the mean Arctic sea ice thickness.more » « less

A three-dimensional numerical model of the Amundsen Sea (Antarctica) was used to simulate the period Jan.2006-Mar.2022 under consistent atmospheric/oceanic forcings, bathymetry/ice shelf topography, and model equations/parameters. The model is an implementation of the Regional Ocean Modeling System (ROMS, https://www.myroms.org/) with extensions for sea ice (Budgell 2005) and ice shelves (Dinniman et al. 2011). It simulates the ocean hydrography and circulation, sea ice thermodynamics and dynamics, and the basal melt of the ice shelves, with a uniform horizontal mesh of 1.5km and 20 topography-following vertical levels. Forcings include the ERA5 reanalysis (3-hourly), 10 tidal constituents from CATS 2008, and ocean/sea ice conditions at the edges of the model domain taken from the 5km-resolution circumpolar model of Dinniman et al. 2020 and from daily SSM/I satellite images. The model outputs are divided into nine directories each containing two years worth of model results (run661-669) in the NetCDF format. Each directory contains: daily-averaged model fields (roms_avg_xxxx.nc), instantaneous snapshots every 3 hours for select fields (roms_qck_xxxx.nc), and instantaneous snapshots every 30 days (roms_his_xxxx.nc). All the metadata information necessary for the interpretation of the model outputs (dimensions, units, etc) is included inside the NetCDF files. The NetCDF files follow the CF conventions and can be opened with various software that are open source and freely available over the Internet. In addition to the model outputs, this archive includes the computer code as well as the input files necessary for reproducing the model outputs of this archive.more » « less

In this study, we developed a 1D Delft3D-FLOW model to simulate the temporal development of the Colville River Delta, Alaska during the most active Arctic seasons: break-up/freshet (spring), open-water (summer), and freeze-up (fall). Simulations focused on the deltaic clinoform (i.e., the cross-sectional view of a delta) and used a floating barge structure to mimic the effects of sea ice on surface waters. Delft3D simulations were coupled with modules written in MATLAB and outputs were process in MATLAB. Arctic delta morphology is impacted by seasonal sea ice coverage which significantly limits wave and river influences and alters river-to-ocean sediment dispersal. However, our knowledge of the morphologic influences of ice on delta morphology is relatively limited. To assess the role of sea ice, our study used a model to explore long-term Arctic delta development under seasonal ice, river, and wave conditions. Delta developmental simulations (spanning 1500 years) included ice-free and ice-affected cases. These cases consisted of simulations with and without waves to separately examine and compare sea ice, river, and wave impacts on Arctic delta evolution. Long-term delta developmental simulations showed ice-affected deltas form a compound clinoform morphology – a coupled subaerial and subaqueous delta separated by a subaqueous platform that resembles the shallow 2 meter platform observed offshore of Arctic deltas. In the model, the presence of nearshore sea ice and river forcing promoted sediment bypassing during break-up, forming a depocenter up to 6 km away from the river mouth and were the key drivers behind platform formation. Furthermore, six varying sea-ice characteristics (extent and thickness) were evaluated to examine effects on delta development for the first 500 years. We found that the compound clinoform morphology modulated by sea ice was heavily dependent on ice conditions, with closer and thicker sea ice produced a more elongated subaqueous platform. In addition to long-term delta developmental simulations, we examined two future scenarios (spanning 450 years) to assess future Arctic delta morphology with less seasonal sea ice coverage and larger waves as predicted by climate models. Modeled future simulations showed Arctic deltas may lose the shallow 2 meter platform feature on centennial timescales by (1) sediment infill or (2) wave erosion. This study highlights the importance of sea ice on Arctic delta morphology and the potential morphologic transitions these high-latitude deltas may experience as the Arctic continues to warm. The dataset includes an example model run file (Delft3D-FLOW and MATLAB) and output of results from the described simulations. Files include: 1) Example Delft3D-FLOW model setup file, MATLAB run script, and ice files for a 1500-year simulation. 2) Processed MATLAB structures and metadata for model results A) Long-term Delta Developmental Outputs (1500-year simulations) i) Ice-free ii) Ice-affected iii) Ice-free with waves iv) Ice-affected with waves B) Varying Sea Ice Characteristics Outputs (500-year simulations) i) Ice matrix (six simulations) C) Future Arctic Delta Scenarios Outputs (450-year simulations) i) Scenario A ii) Scenario Bmore » « less
