Oceanography of the Strait of Bransfield: Environmental parameters, productivity and description of plankton communities
Entry ID: CNDA-ESP_ANT93-0997-HE001


Summary
Abstract: In English:

The objectives of this campaign were:

- Study of the distribution of oxygen, temperature and salinity.
- Determination of nutrient concentration.
- Study of phytoplankton productivity.
- Study of the metabolic activity of microplankton.
- Study of the composition and faunistic aspects of zooplankton.
- Study of the distribution and abundance of icthyoplankton.
- Monitoring of plankton nychthemereal migrations.
- Study of currents and hydrodynamics in South Bay.

Activities

The area studied consisted of 30,000 Km2. A sampling net covering the
Bransfield Strait and South Bay (Livingston Island) was used.
A station where periodic sampling over 36 hours could be done was set up
on the north side of the Gerlache Strait. The following working protocol
wasobserved at each of the stations:- Recording of the vertical profile,
temperature, salinity, conductivity and oxygen by means of a CTD probe.

- Water sampling for salinity, oxygen and nutrient analysis, using Ninskin
bottles at depths of 1, 10, 25, 50, 75 and 100 m.

- Filtration of water samples to determine biomass and peak activity and
nannoplankton.

- Vertical zooplankton catches with a WP2 net.

- Stratified catches with a Bioness multi-seine net to obtain samples of
zooplankton and icthyoplankton.


En Espanol:

Los objetivos de esta campana fueron:

- Estudio de distribucion de oxigeno, temperatura y
salinidad. Determinacion de concentracion de nutrientes.

- Estudio de productividad fitoplanctonica.

- Estudio de la actividad metabolica del microplancton.

- Estudio de la composicion y aspectos faunmsticos del
zooplancton.

- Estudio de la distribucion y abundancia del ictioplancton.

- Seguimiento de las migraciones nictamerales del plancton.

- Estudio de las corrientes y de la hidrodinamica de Bahia
Sur.

Actividades realizadas

El area estudiada comprendio unos 30.000
km2. estableciendose una red de muestreo que cubria el
Estrecho de Bransfield y Bahia Sur (Isla Livingston). La estacion
donde realizar los muestreos periodicos durante 36 horas, fue
establecida en la parte norte del Estrecho de Gerlache. En cada una de
las estaciones se llevo el siguiente protocolo de trabajo:

- Registro del perfil vertical, temperatura, salinidad, conductividad y
ox?geno mediante una sonda CTD.

- Toma de muestras de agua para analisis de salinidad, oxigeno
y nutrientes, mediante botellas Ninskin a 1, 10, 25, 50, 75 y 100 m de
profundidad.

- Filtrado de muestras de agua para determinacyon de la biomasa
y actividad del pico y nanoplancton.- Pescas verticales con una red WP2 para
obtener zooplancton.

- Pescas estratificadas con una multimanga Bioness para
obtencion de muestras de zooplancton e ictioplancton.
