Boundary processes and neodymium cycling along the Pacific margin of West Antarctica
Read more of: Boundary processes and neodymium cycling along the Pacific margin of West AntarcticaNeodymium (Nd) isotopes have been utilized as a tracer of water mass source in the modern ocean and in palaeoceanographic studies, though the oceanic cycling of Nd is not yet […]

Antiphased dust deposition and productivity in the Antarctic Zone over 1.5 million years
Read more of: Antiphased dust deposition and productivity in the Antarctic Zone over 1.5 million yearsThe Southern Ocean paleoceanography provides key insights into how iron fertilization and oceanic productivity developed through Pleistocene ice-ages and their role in influencing the carbon cycle. We report a high-resolution […]

Quantification and assessment of methane emissions from offshore oil and gas facilities on the Norwegian continental shelf
Read more of: Quantification and assessment of methane emissions from offshore oil and gas facilities on the Norwegian continental shelfThe oil and gas (O&G) sector is a significant source of methane (CH4) emissions. Quantifying these emissions remains challenging, with many studies highlighting discrepancies between measurements and inventory-based estimates. In […]

Temperature and concentration affect particle size upon sublimation of saline ice: Implications for sea salt aerosol production in polar regions
Read more of: Temperature and concentration affect particle size upon sublimation of saline ice: Implications for sea salt aerosol production in polar regionsUsing an environmental scanning electron microscope, we quantified for the first time aerosol-sized salt particles formed during the sublimation of sea ice as a function of temperature and concentration. The […]

Statistical comparison of electron loss and enhancement in the outer radiation belt during storms
Read more of: Statistical comparison of electron loss and enhancement in the outer radiation belt during stormsThe near-relativistic electron population in the outer Van Allen radiation belt is highly dynamic and strongly coupled to geomagnetic activity such as storms and substorms, which are driven by the […]
