Our work walks between paleoclimatic and computer fields. BEyOND have been designed and implemented to exploit a large amount of paleodata record and aims to contibute at the reconstriction of the Mediterranean Sea paleoclimatology and paleoceanography.
We decided to focus on the study of the most recent sapropel (S1, 10-6 ka BP) and we firstly developed a methodology that allows to bypass the age variable (not always considered when data are published) and the possibility to correlate cores even when the age is not known. This methodology is based on the core correlation interpolating the sampling depth among different sapropel in different cores by means of SQL queries.
The data introduced in BEyOND derive from other existing databases (e.g., PANGAEA or NOAA ) and published paper. In the next figure, some characteristics of the data as the data source, the basin from which the core data derive, the core depth below the sea level and data categorization are shown.
BEyOND has been implemented with a wide variety the proxies. This interactive tree diagram shows the proxies insert on database BEyOND.
The data in BEyOND has been categorized in: geochemistry, isotopes, sedimentology (sediment grain size and composition), palynology and micropaleontology (coccolithophore, dinoflagellate and foraminifera). This interactive map shows the locations of the cores as a function of this categorization.
BEyOND allows to explore huge volumes of data to extract novel and useful knowledge using data analytics (DA) techniques. In this way, numerous analysis to know about the behavior of the eastern Mediterranean Sea during sapropel deposition (S1) have been made.
Here, different TOC (Total Organica Carbon) trends across three sub-basins (Adriatic, Aegean, Levantine/Ionian) are shown. Horizontal dashed black lines represent sapropel interval (S1) where the beginning of sapropel is 1 and the top is 0 Standardized depth.
This animate plot represents the TOC trends based on the core depth of the cores in the eastern Mediterranean Sea. The horizontal dashed black lines represent sapropel interval (S1).
New analysis are coming. WORK IN PROGRESS!
