Detail

The EU Funding & Tenders Portal presents a Horizon Europe (HORIZON) call, specifically Call 02, a single-stage call for 2027 identified as HORIZON-CL6-2027-02. The topic is "Unlocking a safe operating space for Antarctica and the Southern Ocean" with the specific identifier HORIZON-CL6-2027-02-CLIMATE-04. This call focuses on HORIZON Research and Innovation Actions (HORIZON-RIA) and utilizes a HORIZON Action Grant Budget-Based [HORIZON-AG] Model Grant Agreement (MGA). The planned opening date for submissions is April 20, 2027, with a deadline of September 23, 2027, at 17:00:00 Brussels time.

The expected outcomes of projects funded under this topic include:

Improved multidisciplinary scientific understanding of the Southern Ocean and Antarctic cryosphere, including their interaction, impact, and vulnerability to changes in regional and global climate systems in the near-term (∼2030), mid-term (2050–2060), and long-term (after ∼2060).
Significant contributions to key ocean, cryosphere, climate, and biodiversity monitoring indicators that support international, regional, and global assessments. Development of a regional approach to polar ocean, climate, and biodiversity observations, monitoring, and reporting.
Informed policies for environmental conservation and climate resilience, enabling evidence-based decision-making on polar ocean governance at regional, European, and global levels.
Sustained European leadership in ocean–climate–biodiversity-cryosphere science.
Significant contributions to global scientific assessments (e.g., IPCC, IPBES, and WOA), as well as to the UN Decades of Action of Ocean (2021-2030) and Cryospheric (2025-2034) Sciences, the Antarctica InSync programme (2027 and 2030), the International Polar Year (2032-2033), UN SDGs 13 and 14, and European polar science coordination efforts.

The scope of the proposals should include:

Resolving uncertainties and improving projections of the future of the region, considering irreversible, abrupt, and committed changes in the near-, mid-, and long-term, and their impacts on the Earth’s System.
Advancing understanding of complex interactions and feedbacks between the ocean, atmosphere, sea ice, ice shelves, and land ice dynamics, focusing on Antarctic continental shelves and regions for bottom water formation.
Advancing knowledge of Southern Ocean and sea ice dynamics in the near-, mid-, and long-term, to reduce uncertainties in projected future changes of large-scale ocean circulation and transport. This includes extreme events, fluxes between the ice sheet and the ocean, and the future dynamics of oceanic carbon pools.
Exploring the vulnerability of Southern Ocean ecosystems, including the impacts of climate change, pollution, and other anthropogenic activities on marine biodiversity and ecosystem dynamics. This includes improved control variables for the diversity of all life forms and the development of long-term monitoring systems.
Developing mechanisms to distinguish human-induced environmental changes from natural ones and strategies to protect the Southern Ocean environment, as well as establishing the efficacy of conservation measures.
Improving key monitoring indicators and fostering a regional approach to polar ocean and climate observations, and further the representation of multi-scale interactions in Earth System Models (ESMs) and regional coupled atmosphere–ocean–sea ice–land models.
Advancing capabilities to provide evidence, proposals, and recommendations for policy and protection to prevent the Southern Ocean and its ecosystems from reaching a point of no return.

The actions should contribute to the evolution of the EU Digital Twin of the Ocean and Destination Earth and interface with the Southern Ocean Observing System (SOOS). All in-situ data collected should follow INSPIRE principles and be available through open access repositories (Copernicus, and EMODnet). Efforts should be made to ensure data is FAIR (Findable, Accessible, Interoperable, and Re-usable).

Breakdown

Eligible Applicant Types: All international organisations are exceptionally eligible for funding. A number of non-EU/non-Associated Countries that are not automatically eligible for funding have made specific provisions for making funding available for their participants in Horizon Europe projects. See the information in the Horizon Europe Programme Guide. The eligible applicants are expected to be those capable of resolving uncertainties, improving projections and quantifications of the future of the region, looking at changes in the near-, mid- and long-term (irreversible, abrupt and committed changes), their likelihood, timing, rate, amplitude, and impacts on the Earth’s System (decadal to millennial climate projections, global sea level, ocean circulation, global carbon budget); advance understanding of the complex interactions and feedbacks between the ocean, the atmosphere, sea ice, ice shelves, and land ice dynamics, considering multiple scales and processes simultaneously, with focus on the Antarctic continental shelves where conditions are or will change rapidly and on regions for bottom water formation; advance the knowledge of Southern Ocean dynamics and sea ice dynamics in the near-, mid- and long-term. Better understand the distribution, underlying mechanisms and impacts of changes in the Southern Ocean and sea ice to reduce uncertainties in projected future changes of large-scale ocean circulation and transport, including abrupt, irreversible change/tipping elements and thresholds, collapse of the overturning circulations, regional and global climate and weather systems. This should include extreme events and mid-latitude weather; fluxes between the ice sheet and the ocean; the future dynamics of oceanic carbon pools; explore the vulnerability of Southern Ocean ecosystems, including the impacts of climate change, pollution and other anthropogenic activities on marine biodiversity and ecosystem dynamics changes in the near (∼2030), mid (2050–2060) and long-term (after ∼2060). This includes improved control variables for the diversity of all life forms incorporating also the microbiome and functions (functional diversity), as well as the biocomplexity suitable for measuring biosphere integrity in different facets. Proposals should also contribute to the development or strengthening of long-term, continuous monitoring systems for Southern Ocean biodiversity and ecosystem functioning, in synergy with existing observation infrastructures; develop mechanisms to distinguish human-induced environmental changes from natural ones and develop strategies to protect the fragile environment of the Southern Ocean from human activities and climate change, as well as comprehensively establish the efficacy of Southern Ocean conservation measures for preserving evolutionary potential and those properties that best anticipate change; further improve key ocean, cryosphere, climate and biodiversity monitoring indicators that support international, regional and global assessments and foster the development of a regional approach to polar ocean and climate observations, monitoring and reporting, and further the representation of multi-scale interactions in Earth System Models (ESMs) and regional coupled atmosphere–ocean–sea ice–land models representing key physical, biogeochemical, and biological processes in the polar ocean regions; advance capabilities to provide evidence, tractable proposals and recommendations for commensurate policy and protection, restoration and long-term sustainable management responses to prevent the Southern Ocean and its ecosystems and cryosphere from reaching a point of no return.
