Composition of phytoplankton in the Bransfield Strait and Elephant Island during austral summer of 1999

The authors inform about the composition and distribution of phytoplanktonic community between the first 75 m of depth in Bransfield Strait y around the Elephant island, during the ANTAR X expedition in the 1999 Austral Summer (22nd–29th January 1999). The higher cellular concentration (500 cel/mL)...

Description
Summary:The authors inform about the composition and distribution of phytoplanktonic community between the first 75 m of depth in Bransfield Strait y around the Elephant island, during the ANTAR X expedition in the 1999 Austral Summer (22nd–29th January 1999). The higher cellular concentration (500 cel/mL) was given by the autotrophic nanoplankton, with a high density mainly on the bay stations and down the first 25 m of depth. Among the most representative species we have Leucocryptos marina, Phaeocystis antarctica, the Monadas and the pennate diatoms. Se da a conocer la composición y distribución de la comunidad fitoplanctónica en los primeros 75 m de profundidad en el Estrecho de Bransfield y alrededores de la Isla Elefante, durante la Expedición ANTAR X (22-29 enero de 1999) verano austral de 1999. Las mayores concentraciones celulares (>500 cel/mL) estuvieron dadas por el nanoplancton, con núcleos de altas densidades principalmente en las estaciones marginales y en los primeros 25 m de profundidad. Las especies más representativas fueron Leucocryptos marina, Phaeocystis antarctica, Monadas y las diatomeas Pennatas.
