Deep-Sea Bioluminescence Blooms after Dense Water Formation at the Ocean Surface

2013

The deep ocean is the largest and least known ecosystem on Earth. It hosts numerous pelagic organisms, most of which are able to emit light. Here we present a unique data set consisting of a 2.5-year long record of light emission by deep-sea pelagic organisms, measured from December 2007 to June 2010 at the ANTARES underwater neutrino telescope in the deep NW Mediterranean Sea, jointly with synchronous hydrological records. This is the longest continuous time-series of deep-sea bioluminescence ever recorded. Our record reveals several weeks long, seasonal bioluminescence blooms with light intensity up to two orders of magnitude higher than background values, which correlate to changes in th…

Evolución de la conductividad en la Albufera de Valencia entre 1985 y 2018

2021

La laguna costera de la Albufera de Valencia es una masa de agua oligohalina rodeada de un antiguo marjal, transformado en cultivo del arroz desde hace más de 200 años. La presión de las aportaciones superficiales mantiene la conductividad en valores estables en torno a la media anual, modificada puntualmente al alza sólo en los periodos de sequía. La concentración de cloruros es la variable más relacionada con la conductividad. En el estudio de la serie temporal se observa que en el último decenio hay una tendencia significativa al aumento de los valores mínimos de la conductividad, lo cual indicaría una disminución de la cantidad de agua dulce que llega a la laguna. La medida de esa varia…
