Improving ocean-glider's payload with a new generation of spectrophotometric PH sensor

Ocean gliders have clearly become nowadays useful autonomous platforms addressed to measure a wide range of seawater parameters in a more sustainable and efficient way. This new ocean monitoring approach has implied the need to develop smaller, faster and more efficient sensors without reducing key features like accuracy, resolution, time-response, among others, in order to fit the glider operational capabilities. This work is aiming to present the latest development stages of a new spectrophotometric pH sensor, its integration process into a Wave Glider SV3 platform and the preliminary results derived from an offshore mission performed in subtropical waters between the Canary Islands and Cape Verde archipelagos.Peer Reviewe

ESTUDIO INTERDISCIPLINAR DE LA TUMBA AV DEL ASENTAMIENTO NEOLÍTICO DE LA ESPARRAGOSA (CHICLANA DE LA FRONTERA, CÁDIZ, ESPAÑA) (Interdisciplinary Study of the Tomb AV from the Neolithic Settlement of La Esparragosa (Chiclana de la Frontera, Cadiz, Spain))

El yacimiento de La Esparragosa se encuentra ubicado en la provincia de Cádiz (España), en plena orilla norte del Estrecho de Gibraltar. La tumba que nos ocupa constituye un caso excepcional para la denominada «cultura de los silos», ya que se ha podido documentar en este enterramiento en fosa la existencia de un individuo cubierto por una capa de 477 ejemplares de Ruditapes decussatus (almeja fina). Presentamos un avance del estudio interdisciplinar con dataciones de 14C AMS (una de las cuales es inédita) y TL, antropología física, arqueozoología, funcionalidad y análisis polínico. Estos estudios ponen de relieve la importancia que desempeñó el medio marino para esta comunidad tanto a nivel económico como a nivel ideológico. ENGLISH: The archaeological site of La Esparragosa is located in the province of Cadiz, Spain, on the northern shore of the Strait of Gibraltar. The tomb under consideration is an exceptional example, within the context of the so-called “Silos Fields culture”. Excavations have attested a burial pit for one individual, who was found covered by a layer of Ruditapes decussatus (clam) (477 specimens in total). This article presents the first results of the multidisciplinary studies carried out on this burial, including 14C AMS and TL datings, physical anthropology studies and archaeozoological, archaeometrical, use-wear and pollen analysis. These studies highlight the importance of marine resources for this community, both in economic and ideological terms
