The climate-sensitive waters of the West Antarctic Peninsula (WAP), including its many fjords, are hot spots of productivity that support multiple marine mammal species. Here, we profiled protistan molecular diversity in a WAP fjord known for high productivity and found distinct spatiotemporal patterns across protistan groups.

El proyecto FjordPhyto nace en el 2016 como una colaboración entre investigadores (principalmente de Estados Unidos y Argentina) con la Asociación Internacional de Operadores de Tours Antárticos (IAATO por sus siglas en inglés). Este proyecto de ciencia ciudadana aprovecha las embarcaciones turísticas como plataformas para tomar muestras de agua e...

Las zonas costeras de la Península Antártica se caracterizan por presentar grandes concentraciones de krill en sus aguas. El krill antártico es un crustáceo que juega un rol fundamental en estos ecosistemas, se alimenta principalmente de fitoplancton y es consumido por la megafauna, ballenas, focas, pingüinos, etc. El fitoplancton (protistas autótr...
Article
The western Antarctic Peninsula (WAP) fjords, currently threatened by climate change, are known as high krill congregation areas, however, the primary productivity in relation to phytoplankton groups in these coastal areas remains uncertain. To test this, we studied the specific composition, diversity and cellular carbon content of phytoplankton co...

The western Antarctic Peninsula (WAP) is one of the most productive regions in Antarctica. The nearshore waters, within fjords between 62-67 ºS harbor large Antarctic krill stocks that represent the main food source for higher trophic levels and, consequently overlap with breeding and feeding locations for penguin, seal and whale populations. This...
Presentation
The Western Antarctic Peninsula (WAP) hosts the largest amount of glacio-marine fjords in Antarctica, which distribute meltwater to the ocean. These environments, that are sensitive to climate warming, are expected to be dominated by flagellates, in particular cryptophytes. We studied the spatial and temporal variability of specific phytoplankton c...
Article
The impact of ice-ocean interaction on the Southern Ocean is expected to intensify in the future. However, its influence on phytoplankton community composition remains an open question. The Antarctic Peninsula fjords offer an ideal system to understand the effect of ice-ocean forcing on phytoplankton community, providing an extreme in the spatial g...
Article
Full-text available
The Antarctic Peninsula is one of the fastest warming regions in the world, with over 87% of its glaciers in retreat. The resulting influx of glacial meltwater to the coastal ecosystems may influence the succession patterns of primary producers. It is critical to document these dynamics, gathering time-series data throughout the seasonal growth per...

The western Antarctic Peninsula (WAP) is one of the most affected areas of Antarctica by climate change. The WAP fjords are home for large conglomerations of krill and whales, which suggests that they are areas of high primary productivity, although there are no studies confirming this. This work analyzed the composition of the phytoplankton commun...
Article
Full-text available
The western Antarctic Peninsula (WAP) is one of the most productive regions in the Southern Ocean. However, little is known about the phytoplankton composition in nearshore waters, in fjords and channels between 63º and 67°S, where Antarctic krill and baleen whales are conspicuous. This study represents the first attempt to describe spatial and tem...

A new variety of the marine diatom Haslea crucigeroides, H. crucigeroides var. australis, var. nov., is described here based on phytoplankton samples collected in sub-Antarctic coastal waters of the southern South America and Antarctica. The new taxon was characterized by using light and electron microscopy, and the holotype of H. crucigeroides, th...

El calentamiento climático es un fenómeno de alcance global cuya expresión se encuentra magnificada en las regiones polares (IPCC 2001). Por tales motivos, un claro incremento de grandes témpanos tabulares, provenientes de distintas barreras de hielo, ocurre principalmente en los mares de Ross y Weddell (Bindschadler & Rignot 2001, Ballantyne 2002,...

El presente proyecto versa sobre el estudio de las comunidades microalgales de distintos ambientes antárticos poco explorados por la ciencia, en estrecha relación con los fenómenos vinculados al cambio climático global. El mismo, tiene como objetivo general incrementar el conocimiento sobre la taxonomía y distribución de microalgas marinas, especialmente diatomeas, vinculadas al hielo de origen continental y marino en diversos sectores de la Península Antártica.
