El visor permite la visualización interactiva de los datos de abundancia de zooplancton obtenidos cada mes en las campañas RADIALES (llamadas RADCAN o RCAN desde 2013 en el caso de los tres transectos del Cantábrico: Santander, Gijón y Cudillero). Muestra un panel lateral, donde se puede seleccionar la opción deseada para una serie de variables (estación, año, tipo de representación gráfica, …) y un panel principal donde aparecen los gráficos. Está organizado en cuatro pestañas: [1] ‘Plot’ presenta los datos de una única estación (la lista de todas las estaciones y sus coordenadas geográficas están en https://seriestemporales-ieo.net, y representadas en un mapa en la última pestaña de este visor). [2] ‘multipanel’ muestra simultáneamente los gráficos individuales de todas las estaciones, facilitando la comparación entre ellas. Permite seleccionar el tipo de gráfico. [3] ‘Sampling dates’ representa gráficamente los meses, desde el inicio del proyecto, en que hay datos de abundancia de zooplancton disponibles. [4] ‘Stations Map’ muestra el mapa con la posición de todas las estaciones.

Monthly survey to study thermohaline and biological characterization of water masses in the East-North Atlantic.
Assessment of small pelagic species resources in the Gulf of Lion using echo-integration and trawl hauls to identify the observed echoes. This falls under the SIDEPECHE project.
Characterizing the variability of hydrological and current features and particulate fluxes on the continental rise of the Gulf of Lion and in the deep convection zone. Monitoring of deep benthic communities in the western canyons and on the continental rise of the Gulf of Lion. This cruise was associated with the HERMES and EXTREMA projects.
The area in between the Audierne and St. Nazaire canyons (Gascogne) along the Armorican margin was one of the areas where the "massifs coralliens" were described for the very first time. Within the framework of the HERMES (EC FP6), MiCROSYSTEMS (ESF) and GeNeSis (FWO) projects, this area will be surveyed using multibeam and high resolution seismics during LEG 1. Based on this site survey, the ROV Genesis will be deployed to carry out detailed mapping of these deep-water "hot-spots". Also the hydrography and sediment dynamics of this area will be studied with respect to the steering of the present ecosystems. LEG 2 will focus on the Galicia bank. This location has been assigned as reference area within the ESF project BIOFUN. In addition to a bathymetric and seismic surveying, also biological sampling and experiments are planned here.
The main testable hypothesis of the proposed work is: Atmospheric inputs control rates of primary production and microbial diversity in oceanic waters where nutrients are limiting. The objectives of the project are to: 1. Obtain an improved temporal and spatial estimate of atmospheric dust inputs to the tropical N Atlantic through collections on a dedicated SOLAS process cruise. 2. Obtain an improved estimate of the seawater dissolution of N, P, Fe and Zn species from aerosol dust. 3. Determine the impact of atmospheric dust derived micronutrients on microbial community production and species diversity in the surface microlayer and underlying waters. In addition, researchers from the Archer/Geider group were on-board. The overall aim of their research was to determine the extent to which the photoprotective roles of DMSP and QAs influence their production rates in marine surface waters and hence, the production of their volatile breakdown products. The cruise objectives for this work were to: 1. relate DMSP and QAC concentrations to plankton community structure, light regime, photoinhibition, xanthophyll cycle and MAA accumulation in varying oceanic provinces and over diel cycles. 2. determine the potential for photoinhibition and DMSP/GBT turnover in natural phytoplankton in contrasting oceanic provinces. The cruise departed Tenerife on February 5, 2008, and we have conducted regular stations (typically 2 per day) along the cruise track. The track took us into the oligotrophic Atlantic waters, productive Cape Verde waters, and tropical waters with very high nitrogen fixation (judged initially from the Trichodesmium concentrations). The various researchers and groups have also started a range of biological experiments at different sites along the cruise track. We have encountered a major dust event in week 2, and then from week 3 of the cruise we encountered large amounts of dust. We have visited the TENATSO time series site near the Cape Verdes and have undertaken an extensive set of measurements there. We have collected the atmospheric dust for elemental analyses (at UEA and NOCS), and also to produce leachates which are used on board for biological experiments. We have undertaken sampling of the water column to analyse for dissolved and particulate metals, nutrients, dissolved organic matter, amino acids, hemes, thiols and phytochelatin synthase expression. In addition, nitrogen fixation measurements were undertaken, in tandem with nifh gene sampling. Nitrate uptake experiments have been conducted. Furthermore, bacterial phosphate uptake experiments have been undertaken using addition of collected dust. Halocarbon and DMS gas measurements have been conducted during the cruise. In addition, experiments have been undertaken by the Archer/Geider group on effects of high sun light exposure on DMS and GBT production. The cruise has been very successful with a minimum of lost time.
