Rapid decline in Arctic sea ice coverage and thickness represents one of the most visible indicators of climate change to-date, with profound consequences for global climate, Arctic ecosystems and its people. PHOTA will improve our understanding of climate change impacts in ice covered regions by using innovative technologies to address important knowledge gaps on the bio-physical properties of sea ice and their relationship to food web functioning in ice covered marine ecosystems. PHOTA will be implemented in, benefit from, and provide substantial added value to, two ongoing projects: RCN funded HAVOC (Norwegian contribution to MOSAiC,) and NERC-BMBF funded DiatomARCTIC (see Appendices). PHOTA will also be closely linked and contribute to highly relevant projects, such as the Nansen Legacy, Fram project FADE, Belmont Forum-BiodivERsA funded ACCES, and RCN funded FAABulous. It will mark a new chapter in the study of sea ice in the polar oceans, going beyond others by integrating extensive field-based studies and innovative laboratory experiments into models of habitat suitability and biogeochemistry. The outcomes of PHOTA are highly relevant to a range of stakeholders from the local to the global scale, and will increase the knowledge base on climate-induced changes to marine ecosystem, which is necessary for sound ecosystem-based management by Norway in its regional seas.
