Over the past 30 years, sea ice in the Arctic has declined by 3-4% per decade, making the Arctic the area experiencing the most rapid ecological changes due to climate change. Understanding the consequences of climate change on the Arctic ecosystem is therefore part of the European Union’s (EU) wider efforts. As a consequence of rapid sea-ice loss and increasing temperatures, the abundance, diversity and distribution of low trophic level organisms will be inevitably altered, generating cascading effects through the entire marine food chain from phytoplankton to apex predators. Despite their crucial role as bio-indicators of the Arctic marine ecosystem, the capacity of Arctic cetaceans to adjust their behaviour (foraging, movement patterns) and physiology (fat storage, thermoregulation) to climate-induced perturbations remains poorly understood. By compiling a multi-species long-term dataset covering 25 years and including 2 Arctic (narwhal and bowhead whale) and 2 sub-Arctic (humpback whale and harbour porpoise) apex predators, the WARMM project aims at investigating the behavioural and physiological responses of these species to climate change. The choice of the 4 cetaceans is based on their contrasting diet, habitats and level of activity, making this dataset unique to feed a comparative analysis of how these 4 species will cope with an imminent warming ocean. I will exploit a large existing dataset that will be augmented by physiological data collected during the project to (1) identify the foraging strategies from acoustic and accelerometry data, (2) link the behaviours and physiology to the environment, to finally (3) predict the future responses of apex predators in terms of thermal stress and geographical range. Our project will constitute an unprecedented scientific baseline to advise the EU and the Intergovernmental Panel on Climate Change in mitigating the effects of climate change and safeguarding the Arctic marine biodiversity.

UPGRADE seeks to broaden the research scope of the involved teams, focusing on tackling key challenges in geotechnical and geoenvironmental engineering. Specifically, it aims to pioneer innovative solutions for repurposing waste geomaterials generated by construction and mining industries worldwide. Waste geomaterials represents half of the waste volume generated in EU. These waste geomaterials generally exhibit poor engineering characteristics that prevent their direct use at construction/mining sites. However, if adequately treated, they could represent an excellent resource for construction purposes with significant money saving and reduction in the environmental footprint, thus contributing to the establishment of a circular handling/management of geomaterials. To achieve this, UPGRADE will develop protocols, software and tools to improve the engineering characteristics of waste geomaterials, and to guarantee the performance level over the service life of geostructures built from waste geomaterials considering site-specific conditions. The fundamental concern of UPGRADE is to promote strategies for sustainable use of waste geomaterials generated by geoengineering activities, and to determine how to turn a waste geomaterial into a durable material, with a positive revenue stream. The originality of UPGRADE's approach is that not only it draws expertise on the environment and geotechnics, but also in computer sciences, geochemistry, analytical chemistry, natural resources exploitation, and in the circulatory economy. We intend to form a multidisciplinary consortium composed of 10 academic and 5 industrial beneficiaries and 6 Third Country partners which aim to address this problem. UPGRADE will create an international, interdisciplinary and intersectoral network of creative and innovative researchers and practising engineers ready to face geotechnical and geoenvironmental engineering challenges which arise in the vanguard of technological innovation.

POMP will advance the scientific understanding of how climate change impacts biodiversity and carbon sequestration potential in emerging and rapidly changing polar marine ecosystems, and, through these impacts, the project will evaluate how resilience and adaptation potential in the polar regions are being altered. The aim is to provide new quantitative knowledge of the mitigation potential of blue carbon in emerging coastal and oceanic habitats and to assess the scope for their inclusion in carbon accounting at national and international levels. Our approach is to study each step in the biological carbon flow from CO2-capture by primary producers, through transformations and intermediate storage, to long-term sequestration. We will do this by combining analyses of new and existing data at several Arctic and Antarctic Learning Sites and use this to develop and validate new ecosystem models and remote sensing algorithms. These will then be used to provide large-scale assessments of changes in blue carbon habitat distributions and their CO2 capture and sequestration potential, both now and in the future. The new knowledge generated will be presented to the scientific community and to decision makers and managers as policy briefs to guide the designation of marine protected areas that recognize both diversity and blue carbon potential. The POMP consortium is highly qualified to meet this task with world-leading experts on blue carbon and climate change impacts in the polar regions, and partners that bring together scientific expertise, extensive unpublished data, polar infrastructure, and unique sampling opportunities as well as experience and resources from several national and EU projects directly related to this call. Participation of three Canadian partners eligible for national funding assures excellent opportunities for cross Atlantic collaboration with a pan-Arctic focus.

The rapid pace of climate change in high latitude seas is promoting the emergence of novel ecosystems in coastal regions as well as in the open ocean. SEA-Quester, in accordance with the work program (HORIZON-CL6-2023-CLIMATE-01-3), will conduct field surveys, process studies and model analyses to improve our understanding of the causes and consequences of these emerging polar ecosystems; their potential for blue carbon sequestration, their implications for marine biodiversity, and their role in the global eco-bio-geo-chemical climate system. SEA-Quester will do so with a rigorous analysis of blue carbon stocks and their dynamics, laying the foundations for a fit-for-purpose blue carbon accounting with balance sheets for not just carbon sequestration, but other impacted marine ecosystem services such as fisheries production. SEA-Quester considers all forms of blue carbon in coastal, pelagic, and benthic novel marine ecosystems, living and dead, in the water column and in the sediments, and uses a mechanistic approach to reduce uncertainties in model predictions. A key outcome of SEA-Quester will be to develop a thorough means of quantifying the trade-off between harvesting marine biomass and its net contribution to carbon sequestration: the Biomass-Sequestration amplification factor. SEA-Quester will ensure effective exploitation of the project results in international scientific assessments of Blue Carbon potential and by policy-makers (specifically targeting Nationally Determined Contribution estimates), to ensure dialogue, communication and dissemination to National and European governmental bodies, European citizens and NGO’s, and to provide recommendations for optimizing the monitoring of biodiversity and ecosystem services in emerging polar environments.
