Chemical characterization (nutrients and CO2) of the water masses generated in the Antarctica. Section WOCE A-14
Listed in NASA Earthdata CMR
In English: The oceanographic cruise CITHER 3 (Circulation thermohaline 3), organised by the laboratories of Physical of the Oceans (LPO) from IFREMER-Brest and of the Dynamic and Climatology Oceanaography (LODYC) of the University of Paris, has been carried out on board the French R/V L"Atalante".
Description
The aim was the study of the nutrients distribution and their modelling using a triangular analysis of water masses mixing both with Atlantic and Antarctic origins, as well as the circulation dynamic along the east edge of the Atlantic between 4" 57' N, 11" 47' W y 45" 30' S, 8" 30' W, covering more than 5000 km along the section A14 proposed by the program WOCE (World Ocean Circulation Experiment).
During the cruise 107 stations, spacing about 30 mn, were performed. In each station a CTD cast provided with a rosette with 30 Niskin bottles of 8 L was made. The casts were carried out until the bottom, reaching more that 5200 m in the position 0" 40'N, 6" 59'W. From the 8 L of water collected by the Niskin bottles, the following variables were analyzed: CFCs (1/1 station, all depths), Helium 3 (1/7 station, about 20 depths), Oxygen (1/1 station, all depths), Total CO2 (1/3 station, all depths), Alkalinity (the same than Total CO2 + surface sample at each station), Salinity (1/1 station, all depths), Nutrients (1/1 station, all depths), Dissolved Organic Carbon ( 7 stations along the section A-14; 10 depths), Tritium (the same than Helium 3), Chlorophyll a (1/1 station, surface sample) and Phytoplankton (the same than chlorophyll).

En Espanol: La campana oceanografica CITHER 3 (Circulacion termohalina 3) organizada por los laboratorios de Fasica de los Oceanos (LPO) del Ifremer-Brest y de Oceanografia Dinamica y Climatologia (LODYC) de la Universidad de Paris, se realizado a bordo del Buque oceanografico frances "L'Atalante". El objetivo era el estudio de la distribucion de nutrientes y su modelado en un analisis de mezclas triangular que involucran las distintas masas de agua tanto las de origen Atlantico como los recientes cuerpos de agua Antarticos, asa como la dinamica de circulacion a lo largo del borde Este del Atlantico entre 4?? 57' N, 11" 47' W y 45" 30' S, 8" 30' W, cubriendo mas de 5000 km de la seccion A14 propuesta por el programa WOCE (World Ocean Circulation Experiment) Durante la campana se realizaron 107 estaciones espaciadas alrededor de 30 mn.
En cada estacion se hizo una tirada de la sonde CTD provista de una roseta de 30 botellas oceanograficas Niskin de 8 L de capacidad. Las tiradas se efectuaban siempre hasta el fondo, alcanzando mas de 5200 metros en la posicion 0" 40' N, 6" 59' W. A partir de los 8 L de agua recogidos en las botellas, se analizaron los siguientes parametros: CFCs (1/1 estacion, todas las profundidades), Helio 3 (1/7 estacion, alrededor de 20 profundidades), Oxigeno (1/1 estacion, todas las profundidades), CO2 total (1/3 estaciones, todas las profundidades), Alcalinidad (las mismas que CO2 total + la muestra de superficie en cada estacion), Salinidad (1/1 estacion, todas las profundidades), Nutrientes (1/1 estacion, todas las profundidades), Carbono organico disuelto ( 7 estaciones a lo largo de la seccion A-14; 10 profundidades), Tritio (las mismas que Helio 3), Clorofila (1/1 estacion, la muestra de superficie) y Fitoplancton (las mismas que clorofila)
