The Subantarctic Zone of the Southern Ocean plays a disproportionally large role on the Earth system. Model projections predict rapid environmental change in the coming decades, including ocean acidification, warming, and changes in nutrient supply which pose a serious risk for marine ecosystems.

5 p, 522.5 KB Novel combination coccospheres from Helicosphaera spp indicate complex relationships between species / Sturm, Daniela (The Marine Biological Association of the United Kingdom) ; Langer, Gerald (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Wheeler, Glen (The Marine Biological Association of the United Kingdom)
Coccolithophores play an important role in global biogeochemical cycling, but many aspects of their ecology remain poorly understood, including their heteromorphic haplo-diplontic life cycle. The presence of combination coccospheres in environmental samples, which represent a transition between the lightly calcified haploid (HOL) and heavily calcified diploid (HET) life phases, provides crucial evidence linking the two life cycle phases of a particular species. [...]

The Little ice age (LIA) is the last episode of a series of Holocene climatic anomalies. There is still little knowledge on the response of the marine environment to the pronounced cooling of the LIA and to the transition towards the 20th century global warming. [...]

13 p, 2.2 MB The Role of ocean acidification in Emiliania huxleyi coccolith thinning in the Mediterranean Sea / Meier, K. J. S. (CEREGE (Agency)) ; Beaufort, L. (CEREGE (Agency)) ; Heussner, S. (Centre de Formation et de Recherche sur les Environnements Méditerranéens) ; Ziveri, Patrizia (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Ocean acidification is a result of the uptake of anthropogenic CO₂ from the atmosphere into the ocean and has been identified as a major environmental and economic threat. The release of several thousands of petagrams of carbon over a few hundred years will have an overwhelming effect on surface ocean carbon reservoirs. [...]
