IBAMar 2.0 is a new database created from the oceanographic data
obtained during the development of different oceanographic projects by
the Balearic Center of Spanish Institute of Oceanography (IEO) and
conducted from 1974 and ongoing in the Western Mediterranean basin
(Balearic Sea and Algerian Basin). This database collects data from 27
research projects with 134 oceanographic surveys and 6463 sampling
stations. IBAMar 2.0 database covers 36 year sampling and approximately
210,846 km2 in the Western Mediterranean Sea (WM). The effort applied
for obtaining this data was growing from less than 100 station/year to
more than 700 in the year 2009. IBAMar 2.0 database includes main
hydrographic parameters such as pressure, temperature, salinity and
others as dissolved oxygen, turbidity, chlorophyll-a and nutrients
(nitrates, nitrites, phosphates and silicates). Most of the data from
1990 until now were obtained with multiparametric CTDs, although earlier
data corresponding to cast sampling with Niskin bottles were
incorporated too. The main goal of this database is to establish a
climatology for the most significant variables to study the existence of
decadal cycles or long-term trends, trying to better understand the
behaviour of the hydrographic conditions of the Spanish Mediterranean
coast, at both seasonal and interannual time scale and long term. From
these studies is possible to provide answers on topical issues as the
thermohaline anomaly of the deep waters of WM, the spatial distribution
of dissolved oxygen minimum, or the effects of the Climate Change on the
hydrodynamics characteristics of the study area [1]. Future work
includes data quality control based on standard protocols like [2] and
publishing IBAMar 2.0 (including next surveys) on the website of the
Mediterranean Group on Climate Change of IEO
(http://www.ma.ieo.es/gcc/). There, the data could be obtained
summarized as seasonal climatology. These will include horizontal
sections at standard depths and some representative vertical sections.
Spatial and temporal resolution as well as data quality control will be
discussed. This contribution will also present some examples that may
contribute to our understanding of hydrological changes and global
warming in the Mediterranean Sea. [1] M. Vargas-Yáñez,
