With more than 90% of global warming occurring in the ocean, sea level rise doubling in the past 30 years, and the ever-increasing frequency and intensity of extreme events, ocean observations are essential for understanding and addressing some of these most pressing global challenges.
Global fungal diversity is estimated to range in the millions, yet it remains severely underexplored, especially in extreme environments. Fewer than 5% of species have been officially identified and characterised. Estimates suggest that 70%–90% of soil fungi remain uncultivable…
The introduction of new processes in biogeochemical models brings new model parameters that must be set. Optimization of the model parameters is crucial to ensure that model performance is based on process representation (i.e., functional forms) rather than poor choices of input parameter values.
Monitoring variability in predator diets can highlight key parameters for understanding and managing marine ecosystems. Penguin diets provide useful indicators of ecosystem variability and several species, including Adélie penguins (Pygoscelis adeliae)…

Understanding past climate is essential to our knowledge of how our current climate system operates, and how it might respond to future change. Techniques to reconstruct climate history are challenging, and both accuracy and certainty are hampered by the quality of the datasets used.
Antarctic krill (Euphausia superba) are a circumpolar species with an omnivorous diet. Knowledge of krill diet within different regions will help predict how environmental change may impact local krill populations. Krill from the Atlantic, Indian…
Precision, accuracy, and temporal resolution are key to making full use of atmospheric trace gas records in ice cores. These aspects will become especially crucial for ice cores that aim to extend the ice core record to the last 1.5?Myr, i.e., across the Mid-Pleistocene Transition…
Background: Accurate predictions of animal occurrence in time and space are crucial for informing and implementing science-based management strategies for threatened species. Methods: We compiled known, available satellite tracking data for pygmy blue whales in the Eastern Indian Ocean (n?=?38)…
Mapping Antarctic Specially Protected Areas (ASPAs) remains a critical yet challenging task, especially in extreme environments like Antarctica. Traditional methods are often cumbersome, expensive, and risky, with limited satellite data further hindering accuracy.
Due to its persistence and potential ecological and health impacts, mercury (Hg) is a global pollutant of major concern that may reach high concentrations even in remote polar oceans. In contrast to the Arctic Ocean…
