Abstract
The fast decline of Arctic sea ice in the last decades is commonly viewed as manifestation of the climate change. The sea ice reduction exposes a large area of the previously ice-covered Arctic Ocean to the atmosphere, and intensifies air-ocean exchanges. This leads to changes in ocean circulation and impacts ocean ecosystems. Due to multiple influences between ocean and sea ice the future state of the Arctic ecosystem is not well understood.
The proposed project will address changes in the ocean currents in the Arctic Ocean and the regional differences the marine ecosystems between the two provinces in the Arctic Ocean: the Atlantic and Pacific sectors. Using historical data, new observations and high-resolution ocean and ecosystem models the project will investigate current changes in the ocean currents, nutrients supply and ecologically important key substances, such as CO2. The data from the "Multidisciplinary drifting Observatory for the Study of Arctic Climate" Observational Programme (MOSAiC; see also http://www.mosaic-expedition.org/) will be used. The programme is planned to take place in 2019/2020 and will cover a large part of the Eurasian Basin and central Arctic.
The project will examine nutrient supply to the upper ocean and the changes in marine ecosystems in the future climate change scenarios for the next assessment of the Intergovernmental Panel on Climate Change (IPCC) and will quantify the impact of the emerging new Arctic climate on the ecosystems, fisheries, Arctic industries and societies. The project brings together leading researchers from the UK, Germany and Sweden, building on the research expertise in the Polar Sciences. The project will facilitate a new understanding of the Arctic and climate in the UK, Europe and worldwide.

Planned Impact
The rapid decline of Arctic sea ice in the last decades is commonly viewed as manifestation of the climate change. This sea ice reduction has lead to debates in the maritime industries and beyond on the possibility of an increase industrial activities in the area, including in cargo transportation and off-shore exploration, and whether the economical benefits outweigh the risk and the potential damage to the environment. This has generated political debates over the future of the Arctic, public interest, discussions in the media and also a momentum in the Arctic research. For example there was a a Royal Society meeting on Arctic sea ice in 2014 and series of Arctic-related events, including "The Year of Polar Prediction" coordinated by the WMO and the revision of the new Polar Code for Arctic navigation completed in 2016. The knowledge of how the changing Arctic sea ice and ocean can affect the Arctic environment and what are the timescales for the change is crucial for mitigation of the climate impacts in the region and policy making. The change affects UK and international governments and businesses. Better scientifically-based predictions of Arctic sea ice, ocean and ecosystems has a substantial economical value, and also impacts social and environmental policies.
This project brings together leading researchers from the UK and Germany, with the partnership from the Sweden, capitalising on the critical mass of the expertise in the Arctic sea ice, ocean and ecosystems modelling, Arctic physical oceanography and ecosystems, and climate science.
The key practical outcome from the project will be future projections of the changes in the Arctic ecosystems during the 21st century. These projections will include analyses of model uncertainty and will quantify the impact of the emerging influence of the new Arctic physical climate on the ecosystems, helping assessments of the impact on the fisheries, Arctic industries and societies. The results will be utilised for the offshore industries, marine transport and insurance sector. They will assist making informed policy and sustainable development decisions for the Arctic regions. The principal beneficiaries will be: the climate research and forecasting centres, e.g. the UK Met Office; climate research (the IPCC); policy makers (e.g., DEFRA and FCO) and international independent advisory organisations, such as the Arctic Council and Artic Economic Council; off-shore O&G industries, shipping classification societies; environmental monitoring bodies, e.g., Arctic Monitoring and Assessment Programme of the Arctic Council Working Group and the general public and local communities.

Title | Coastal permafrost erosion model |
Description | Generic off-line pan-Arctic modelling tool of the coastal permafrost erosion has been developed in the framework of the new coupled ocean-sea ice-waves NEMO-CICE-WW3 model and can be used in other coupled and forced ocean-wave models. The developed model follows closely Wight's model (Barnhart 2014) and calculates coastal erosion due to wave action and sea level change anomalies, with added permafrost probability and adjustment for rocky/non rocky coast. The erosion rates depend on geological permafrost temperature, probability (PEX); ice content (ACDD) and marine parameters (SST, SWH, wave period). ACDD has the required variables to calculated organic carbon, nitrate and phosphate fluxes from erosion rates. The erosion model uses inputs from the coupled ocean-sea ice-waves model and land permafrost model and allows simulating permafrost erosion rates and fluxes of the terrigeneous matter, including fluxes of carbon, nutrients and contaminants. |

Provided To Others? | Yes |
Impact | The pan-Arctic model of the coastal permafrost erosion model can provide data on erosion rates for the current and future climate states and leads to the improved simulations of the marine biogeochemistry by accounting for the input of the land biogeochemical fluxes and land contaminants into the marine environment. The model provides coastal permafrost retreat data which allows assessing risks for the shore stability, shore settlements, on-shore structures and installations and can help coastal infrastructure development planning and climate impacts mitigation. The model can used for the ice barrier erosion assessments in the Antarctica. |

Title | Model to assess combined risks from ocean currents, tides, waves and sea ice for offshore operations in the polar oceans and ice-covered seas |
Description | Off-line model method and tool to calculate critical loads and safety limits to navigate in sea ice has been developed in the framework of the new coupled ocean-sea ice-waves NEMO-CICE-WW3 model by Drs Stefanie Rynders and Yevgeny Aksenov. The model uses inputs from the coupled ocean-sea ice-waves model and applies newly developed dynamical and static ice loads calculations, along with the safety ice navigation limits for different ship classes and critical loads from combined effects from currents and waves. |
Type Of Material | Improvements to research infrastructure |
Year Produced | 2022 |

Title | Intercalibrated dataset of in situ dissolved organic matter fluorescence from CTD casts in the Central Arctic (2012 and 2015) during Dana cruise NAACOS and POLARSTERN cruise PS94 |
Description | Here we present a merged and calibrated dataset of temperature, practical salinity and dissolved organic matter (DOM) fluorescence obtained from several Ice Tethered Profilers (ITPs) deployed across the central Arctic (2011-2016). The data offer a unique spatial coverage of the distribution of DOM in the surface 800 m below Arctic sea ice. A total of 5044 profiles are gathered. The ITP data are level 3 data products pressure-bin-averaged at 1-db vertical resolution with depth down to either 200 or approximately 750 m. Data (max 800m depth) from CTD casts made during two oceanographic cruises are also included. These were used as part of the calibration and validation of the ITP calibration routines. The cruises were PS94 (ARK-XXIX/3) with POLARSTERN in 2015 and NAACOS with DANA in 2012. The presented DOM fluorescence data are smoothed, corrected for instrument drift and calibrated to provide intercomparable data across the sensors. Fluorescence is reported in Raman Units (nm-1), and comparable to laboratory measurements conducted according to current community recommendations. |

The ITP data are level 3 data products pressure-bin-averaged at 1-db vertical resolution with depth down to either 200 or approximately 750 m. Data (max 800m depth) from CTD casts made during two oceanographic cruises are also included. These were used as part of the calibration and validation of the ITP calibration routines. The cruises were PS94 (ARK-XXIX/3) with POLARSTERN in 2015 and NAACOS with DANA in 2012. The presented DOM fluorescence data are smoothed, corrected for instrument drift and calibrated to provide intercomparable data across the sensors. Fluorescence is reported in Raman Units (nm-1), and comparable to laboratory measurements conducted according to current community recommendations. |

Title | NOC FRONTIER ARC36 NEMO-SI3 coupled sea ice-ocean model and tests with three rheology settings |
Description | NOC FRONTIER ARC36 NEMO-SI3 coupled sea ice-ocean model and tests with three rheology settings (aEVP, EAP and EAP-isotropic) are archived on ARCHER-II and BODC. Code, configuration settings are on ARCHER-II and at https://zenodo.org/record/6628486#.ZAn6fxP7RT4 |
Type Of Material | Database/Collection of data |

Impact | The model integrations show that sea ice concentration, lead positions (and linear kinematic features LKFs), and ice drift divergence are different in all the three rheology options. EAP shows more LKFs than the aEVP with more acute intersection angles, in better agreement with observations. In EAP LKFs change significantly in response to wind forcing variations on sub-daily scales, with aEVP less so. EAP simulations show a large degree of ice anisotropy. Isotropic settings (anisotropy is set constant=0) of EAP show a different pattern of more stepped leads, which also appear in real sea ice. This points out the key role of sea ice anisotropy evolution for realistic simulations. EAP provides a promising alternative for high resolution sea ice modelling, simulating ice plates dynamics impact on ocean eddies. |
Title | Off-line model to assess combined risks from ocean currents, tides, waves and sea ice for offshore operations in the polar oceans and ice-covered seas |
Description | Off-line model to calculate critical loads and safety limits to navigate in sea ice has been developed in the framework of the new coupled ocean-sea ice-waves NEMO-CICE-WW3 model by Drs Stefanie Rynders and Yevgeny Aksenov (NOC). The model uses inputs from the coupled ocean-sea ice-waves model and applies newly developed dynamical and static ice loads calculations, along with the safety ice navigation limits for different ship classes and critical loads from combined effects from currents and waves. The model is generic and can use netcdf input from any ocean-sea ice-wave models. The model produces timeseries and spatial maps of the loads and maps safety areas for marine operations, including ships navigation and fixed off-shore structures exploitation. |
Type Of Material | Computer model/algorithm |

Impact | The model allows assessments of the combined navigational and structural integrity risks of the fixed and floating off-shore installations from sea ice drift and compressions, ocean waves, currents and tides regionally and globally in all the seasons, as for the present day conditions, as well as for the future climates. This is essential for the marine safety planning and forecasting. |

Title | Off-line pan-Arctic model of the coastal permafrost erosion |
Description | Off-line pan-Arctic model of the coastal permafrost erosion has been developed in the framework of the new coupled ocean-sea ice-waves NEMO-CICE-WW3 model. The erosion model uses inputs from the coupled ocean-sea ice-waves model and land permafrost model and allows simulating permafrost erosion rates and fluxes of the terrigeneous matter, including fluxes of carbon, nutrients and contaminants. The developed model follows closely Wight's model (Barnhart 2014) and calculates coastal erosion due to wave action and sea level change anomalies, with added permafrost probability and adjustment for rocky/non rocky coast. The erosion rates depend on geological permafrost temperature, probability (PEX); ice content (ACDD) and marine parameters (SST, SWH, wave period). ACDD has the required variables to calculated organic carbon, nitrate and phosphate fluxes from erosion rates. |
Type Of Material | Computer model/algorithm |

Impact | Arctic coastal erosion is an increasing problem via threat to infrastructure, also it affects the marine environment. Arctic coast is mainly soft sediment permafrost. Sea ice protection is decreasing, leading to increased erosion from waves and melting. The pan-Arctic model of the coastal permafrost erosion model leads to the improved simulations of the marine biogeochemistry by accounting for the input of the land biogeochemical fluxes and land contaminants into the marine environment. The model offers quantitative assessments of the future erosion trends, informing mitigation scenarios of the coastal structure integrity and settlements safety. The model can be used to assess melting and collapse of the ice barrier from the waves in the Antarctica and sea level rise. |

Title | ARC36 stand-alone SI3 Arctic configuration |
Description | SI3 regional configuration of the Arctic This is a configuration of the NEMO community ocean model based on the ORCA2_SAS_ICE reference configuration. The NEMO code is available from https://forge.nemo-ocean.eu/nemo/nemo. This configuration has a resolution of 1/36 degree and is a cut-out of the global 1/36 configuration: https://github.com/immerse-project/ORCA36-demonstrator. The code base is a pre-4.2.0 NEMO version, the model source code can be found in the file src_tar. Model setup Follow the instructions on https://sites.nemo-ocean.io/user-guide/index.html to download and install the NEMO model version 4.2.0. Swap the src directory for the one in the tar file src_tar. Compile the ORCA2_SAS_ICE reference configuration. Put the rest of the files in this zenodo archive in the EXP00 directory, except the namelist_cfg_for_DOMAINcfg file which goes into tools/DOMAINcfg along with the grid files to be downloaded later. The files provided include example configuration namelist files namelist_cfg and namelist_ice_cfg. The atmospheric forcing used is the Drakkar forcing set (DFS) version 5.2, year 2008. The atmospheric forcing is interpolated on-the-fly, using the weights files. The weights were calculated using the nemo WEIGHTS tool. For the ocean (bottom) boundary the World Ocean Atlas 2018 multidecadal monthly averages are used. The data is already interpolated onto the ARC36 grid. Interpolation was done using the SOSIE tool. Files provided are monthly averages of sea surface salinity and temperature. Finally, the model grid domain_cfg.nc needs to be created. Download the ORCA36 files from ftp://ftp.mercator-ocean.fr/download/users/cbricaud/BENCH-ORCA36-INPUT.tar.gz, see the ORCA36 demonstrator github page. The necessary files are the coordinates and bathymetry files. To cut out the Arctic domain use ncks -F -d y,7000,,1 in.nc out.nc. Put in tools/DOMAINcfg and use the DOMAINcfg NEMO tool to create the domain_cfg.nc file using the file namelist_cfg_for_DOMAINcfg as namelist_cfg. The resulting file is large (122GB) therefore executing in parallel mode is required. The individual processor files need to be merged into one, use the REBUILD_NEMO tool. Put the resulting domain_cfg.nc file into EXP00 and run NEMO following the instructions. The ARC36 configuration was set up and run on ARCHER2 using 594 NEMO processors and 12 XIOS processors. |
