The Great Calcite Belt (GCB), a region of high calcite concentration from coccolithophores, covers 60 % of the Southern Ocean area. We examined the influence of temperature, macronutrients, and carbonate chemistry on the distribution of mineralizing phytoplankton in the GCB. Coccolithophores occupy a niche in the Southern Ocean after the diatom spring bloom depletes silicic acid.... Continue Reading →
Wind-driven ocean dynamics impact on the contrasting sea-ice trends around West Antarctic
Since late 1978, Antarctic sea-ice extent has overall expanded in all seasons in stark contrast to the retreating Arctic sea-ice extent. However, while the sea-ice extent around East Antarctica has increased monotonically, the sea-ice around West Antarctica exhibits regionally and seasonally inhomogeneous trends. For instance, Antarctic sea-ice extent in the East Pacific has decreased substantially... Continue Reading →
