<p>New hydro-oceanographic data were collected in the Arctic Ocean during HIGN NORTH20 marine geophysical campaign performed in July 2020, in a COVID-19 pandemic period. HIGH NORTH20 was developed as part of the IT-Navy HIGH NORTH program, a Pluriannual Joint Research Program in the Arctic devoted to contribute to oceans knowledge in order to ensure ocean science improving conditions for sustainable development of the Ocean in the aim of United Nations Decade of Ocean Science for Sustainable development and the GEBCO - SEABED 2030 project. In order to contribute in exploration and high-resolution seabed mapping new data was collected using a multibeam echosounder (EM 302 - 30 kHz). The particular sea ice environmental condition with open-sea allowed to survey and mapping the Molloy Hole, the deepest sector of the Arctic Ocean, a key area in the global geodynamics and oceanographic context. A 3D model of the Molloy Hole (804 km<sup>2</sup>) and the detection of the deepest seafloor (5567m - 79° 08.9’ N 002° 47.0’ E) was obtained with a 10x10m grid in compliance to the IHO standards.</p>

<p>In order to study the future aerosol burdens and their radiative and climate impacts over the Arctic (>60 °N), future (2015-2050) simulations have been carried out using the GISS-E2.1 Earth system model. Different future anthrpogenic emission projections have been used from the Eclipse V6b and the Coupled Model Intercomparison Project Phase 6 (CMIP6) databases. Results showed that Arctic BC, OC and SO<sub>4</sub><sup>2-</sup> burdens decrease significantly in all simulations following the emission projections, with the CMIP6 ensemble showing larger reductions in Arctic aerosol burdens compared to the Eclipse ensemble. For the 2030-2050 period, both the Eclipse Current Legislation (CLE) and the Maximum Feasible Reduction (MFR) ensembles simulated an aerosol top of the atmosphere (TOA) forcing of -0.39±0.01 W m<sup>-2</sup>, of which -0.24±0.01 W m<sup>-2</sup> were attributed to the anthropogenic aerosols. The CMIP6 SSP3-7.0 scenario simulated a TOA aerosol forcing of -0.35 W m<sup>-2</sup> for the same period, while SSP1-2.6 and SSP2-4.5 scenarios simulated a slightly more negative TOA forcing (-0.40 W m<sup>-2</sup>), of which the anthropogenic aerosols accounted for -0.26 W m<sup>-2</sup>. The 2030-2050 mean surface air temperatures are projected to increase by 2.1 °C and 2.4 °C compared to the 1990-2010 mean temperature according to the Eclipse CLE and MFR ensembles, respectively, while the CMIP6 simulation calculated an increase of 1.9 °C (SSP1-2.6) to 2.2 °C (SSP3-7.0). Overall, results show that even the scenarios with largest emission reductions lead to similar impact on the future Arctic surface air temperatures compared to scenarios with smaller emission reductions, while scenarios with no or little mitigation leads to much larger sea-ice loss, implying that even though the magnitude of aerosol reductions lead to similar responses in surface air temperatures, high mitigation of aerosols are still necessary to limit sea-ice loss. </p>

<p><strong>Monitoring Svalbard’s environment and cultural heritage through citizen science by expedition cruises</strong></p><p>Michael K. Poulsen1, Lisbeth Iversen2, Ted Cheeseman3, Børge Damsgård4, Verena Meraldi5, Naja Elisabeth Mikkelsen6, Zdenka Sokolíčková7, Kai Sørensen8, Agnieszka Tatarek9, Penelope Wagner10, Stein Sandven2, and Finn Danielsen1</p><p>1NORDECO, 2NERSC, 3PCSC, 4UNIS, 5Hurtigruten, 6GEUS, 7University of Oslo, 8NIVA, 9IOPAN, 10MET Norway</p><p><strong>Why expedition cruise monitoring is important for Svalbard. </strong>The Arctic environment  is changing fast, largely due to increasing temperatures and human activities. The continuous areas of wilderness and the cultural heritage sites in Svalbard need to be managed based on a solid understanding.</p><p>The natural environment of Svalbard is rich compared to other polar regions. Historical remains are plentiful. The Svalbard Environmental Protection Act aims at regulating hunting, fishing, industrial activities, mining, commerce and tourism. Expedition cruises regularly reach otherwise rarely visited places.</p><p><strong>Steps taken to improve environmental monitoring. </strong>A workshop for enhancing the environmental monitoring efforts of expedition cruise ships was held in Longyearbyen in 2019, facilitated by the INTAROS project and the Association of Arctic Expedition Cruise Operators  (https://intaros.nersc.no/content/cruise-expedition-monitoring-workshop) with representatives of cruise operators, citizen science programs, local government and scientists. They agreed on a pilot assessment of monitoring programs during 2019.</p><p><strong>Results show the importance of cruise ship observations. </strong>The provisional findings of the pilot assessment suggest thatexpedition cruises go almost everywhere around Svalbard and gather significant and relevant data on the environment, contributing for example to an improved understanding of thestatus and distribution of wildlife. Observations are often documented with photographs. More than 150 persons contributed observations during 2019 to eBird and Happywhale. iNaturalist, not part of the pilot assessment, also received many contributions. The pilot assessment was unable to establish a useful citizen science program for testing monitoring of cultural remains.</p><p><strong>Conclusions relevant for monitoring and environmental management. </strong>Cruise ships collect environmental data that are valuable for the scientific community and for public decision-makers. The Governor of Svalbard isresponsible for environmental management in Svalbard. Data on the environment and on cultural remains from expedition cruises can be useful for the Governor’s office. Improved communication between citizen science programs and those responsible for environmental management decisions is likely to increase the quantity of relevant information that reaches public decision makers.</p><p><strong>Recommendations for improving the use of cruise ship observations and monitoring.</strong></p><ul><li>1) All cruise expedition ships should be equipped with tablets containing the apps for the same small selection of citizen scienceprograms so that they can easily upload records.</li> <li>2) Evaluation of data that can be created and how such data can contribute to monitoring programs, to ensure that data is made readily available in a form that is useful for institutions responsible for planning and improving environmental management.</li> <li>3) Clear lines of communication between citizen science program participants, citizen science program organizers, the scientific community and decision makers should be further developed.</li> <li>4) Developing expedition cruise monitoring is of high priority in Svalbard, but is also highly relevant to other polar regions.</li> <li>5) Further work is necessary to fully understand the feasibility and potential of coordinated expedition cruise operator based environmental observing in the Arctic.</li> </ul>

<p>This communication project aims to increase our understanding of climate processes, the Arctic and the importance of research through the active involvement of primary to junior high school students. The project is based on NERSC's ongoing activity in the Arctic Sea, collaborating with several projects and utilizing a concept introduced by the US Coast Guard. Students of four primary schools in western Norway produced a total of 230 small wooden boats.  Together with a comparable number of boats produced by US students they were subsequently launched on the ice in the Arctic Ocean by the coast guard ship KV Svalbard in August and November 2020 as part of scientific cruises. Scientific buoys were also launched, transmitting their position and surface temperature. Through a dedicated web-site students and teachers could follow the drift in near real time. Boats are uniquely branded with a web address, so they may be reported if found after drifting ashore.</p><p>The project website serves both as a communication hub between scientists and students and teachers and to reach out to a wider audience. Several films were produced in this regard. Webinars were held by NERSC scientists on climate and ocean science topics and crew members from K/V Svalbard on work and life onboard a coast guard vessel. Feedback from the teachers will also be presented.</p>
