Nowadays it is very common to hear in the media that a climate change is taking place. But if we really want to understand what climate is like today, we must know what it was like in the past and what our planet's response was to the different climatic conditions. To study what happened in the past we have to use natural files, such as sedimentary records.

Palaeoclimatic reconstruction is possible through a wide variety of natural indicators that are present in the sedimentary records. These have a great importance in different scientific areas (physical, chemical and biological), and can be obtained by different biogeochemical processes and depending on the origin of the records that we use, we will obtain different resolutions.

The Mediterranean Sea has very peculiar characteristics. As it is a semi-enclosed basin and has contributions from different erosion zones, such as the Rif in Morocco and the Betic System in southern in Spain, it has a high sedimentation rate, making it an excellent archive for high resolution analysis in marine sediments. This is one reasom why the Sea of ​​Alboran is ideal to study the marine sedimentary record.

My research is focused in the reconstruction climate variability and paleoceanography conditions in the wester Mediterranean, in relation on develoment and use geochemist proxies for paleoenvironmental reconstruction and the understanding of biochemist cycles poorly known as the Barium, of great importance due to its relationship with the carbon cycle and global change. The results obtained have been published in high impact journals, mostly from the first quartile.
