ARCTIC: Campaign in the Arctic Glacial Ocean
Entry ID: CNDA-ESP_ARTICO_REN2001-4909-E_ANT


Summary
Abstract: In English:

They were done 11 stations: five along the transect between the Norwegian coast
and Bjornoya island (Bjornoya transect), five along the transect to the South
of Spitzbergen (South Cap transect) and the most northern station.

Samples were taken for the following determinations:

-Diversity of eukaryotic picoplankton
Samples filtered by GF/F filters for the determination of the chlorophyll a,
and samples collected on 0.6µm pore-size for the determination of the
picoplankton by epifluorescence microscopy. Samples filtered on 0.2µm and
0.6µm pore-size to carry out FISH with stramenopilos probes. Samples
pre-filtered on 3µm pore-size and collected in filters on 0.2µm pore-size for
the nucleic acids of the picoplankton. Samples to make enrichment cultivations
of heterotrophic flagellates. During the campaign 3 experiments were done and
all the picoplankton samples by epifluorescence were counted.

-Picoplankton comparison by means of microscopy and HPLC. Samples filtered by
GF/F filters to analyzed the pigments by HPLC. Samples of 250 ml filtered with
phormol-hexamina to determinate the microplankton by invested microscopy

The following was also sampled:

Filtered samples and dried off to the air to examine the coccolithophore algae
by electron microscopy. Samples filtered by GF/F filters and frozen for the
determination of the sulphur particulated organic compounds DMSP and DMSO.

En Espańol:

Se ocuparon 11 estaciones: cinco a lo largo del transecto entre la costa
noruega y la Isla de Bjornoya (transercto Bjornoya), cinco a lo largo del
transecto al sur de Spitzbergen (transecto South Cap) y la estacion mas
septentrional.

Se tomaron muestras para las siguientes determinaciones:

-Diversidad de picoplancton eucariotico.
Muestras filtradas por filtros GF/F para la determinacion de la clorofila a, y
muestras por filtros de 0,6µm de poro para la determinacion del picoplancton
por microscopia de epifluorescencia. Muestras filtradas sobre filtros de 0,2µm
y 0,6µm de poro para la realizacion de FISH con sondas de estramenopilos.
Muestras prefiltradas por filtros de 3µm de poro y recogidas en filtros de
0,2µm de poro para los acidos nucleicos de la comunidad picoplanctonica.
Muestras para realizar cultivos de enriquecimiento de flagelados heterotrofos.
Se realizaron tres experimentos durante la campańa y se contaron todas las
muestras de picoplancton por epifluorescencia.

-Comparación del fitoplancton mediante microscopia y HPLC.
Muestras filtradas por filtros GF/F para el analisis de pigmentos por HPLC.
Muestras de 250 ml filtradas con formol-hexamina para la determinación del
microplancton por microscopia invertida.

Se recogieron ademas:

Muestras filtradas y secadas al aire para examinar las algas cocolitoforales
por microscopia electronica de barrido. Muestras filtradas por filtros GF/F y
congeladas para la determinación de los compuestos orgánicos de azufre
particulados DMSP y DMSO.
