6 files, This documentation discusses the procedures and methods used to measure total carbon dioxide (TCO2), total alkalinity (TALK), and pH at hydrographic stations during the R/V Maurice Ewing cruise in the South Atlantic Ocean on the A17 WOCE section. Conducted as part of the World Ocean Circulation Experiment (WOCE), this cruise was also a part of the French WOCE program consisting of three expeditions (CITHER 1, 2, and 3) focused on the South Atlantic Ocean. The A17 section was occupied during the CITHER 2 expedition, which began in Montevideo, Uruguay, on January 4, 1994 and finished in Cayenne, French Guyana, on March 21, 1994. During this period the ship stopped in Salvador de Bahia and Recife, Brazil, to take on supplies and exchange personnel. Upon completion of the cruise the ship transited to Fort de France, Martinique.

This dataset presents information on fish eggs and larval abundances at different layers of the water column in two surveys carried out in June and November 2005 in the NW Mediterranean Sea. The vertical distributions of fish early stages of ca. 60 taxa was investigated. The larvae of the majority of shelf species that appeared in summer showed a very superficial vertical distribution, above the thermocline, the DFM and the maximum biomass of micro- and mesoplankton, and showed no signs of diel migrations along the water column. In autumn, the vertical distributions patterns of fish larvae were slightly wider, This research was funded by project "Análisis de la estructura espacial de los primeros estadios de desarrollo de merluza, anchoa y sardina en el Mediterráneo noroccidental. Interacción con la hidrografía y la disponibilidad trófica". CTM2004-03510-C02-01/MAR, Peer reviewed

This dataset presents information on distribution, abundance and diversity of fish eggs and larvae, integrated throughout the water column, in June and November 2005 in the northwestern Mediterranean Sea. Results indicated that most fish species reproduce in early summer and fewer in the autumn mixing period. Summer samples were composed by a higher number of taxa belonging to both oceanic and shelf dwelling species, with dominance of two clupeiforms, Engraulis encrasicolus and Sardinella aurita in the shelf zone, "Análisis de la estructura espacial de los primeros estadios de desarrollo de merluza, anchoa y sardina en el Mediterráneo noroccidental.
