Questions Asked and Needs • Managing living and non-living resources, monitoring environmental changes in the sea and protecting the marine environment, require long time series of observations of: Dissolved Oxygen: low oxygen levels in the upper layers, can result in reduction of higher life forms, release of toxic forms of metals and pathology in living organisms. Nutrients: changes in nutrient fluxes can alter primary production and bio-diversity, and can directly affect aquaculture and fishing activity. Temperature and Salinity: are the primary indicators of climate change and allow the computation of other derived parameters such as density, sound velocity, and geostrophic current, widely used in scientific and technical studies. • The need for marine database and appropriate data management is particularly crucial in the Mediterranean and Black Sea : for environmental studies, for qualification of new data that requires statistics of expected values, for initialisation and qualification of numerical models • When the project started, not all of the data collected by the scientific laboratories of the bordering countries were inventoried and safeguarded. Data never archived in a public data bank are in danger of being lost. Studies show that without appropriate safeguarding, about 30% of them will be lost within 10 years. Data collected in variable environment cannot be remade.
Objectives and Tasks • Task 1: to inventory from a common cruise catalogue, compile, safeguard and make available historical data sets of : Temperature, Salinity, Oxygen, Nitrate, Nitrite, Ammonia, Total Nitrogen, Phosphate, Total Phosphorus, Silicate, H2S, pH, Alkalinity, Chlorophyll-a • Task 2: to make the archived data sets comparable and compatible by using the common MEDATLAS protocol for formatting and quality checking • QC involves automatic and visual checks and takes into account regional statistics • Task 3 : to prepare and disseminate qualified value added products by developing and using efficient gridding, and mapping methodology developed with the Variational Inverse Model of MODB (MAS2-CT93-0075-BE) • Task 4: to publish the observed data, gridded data, maps, software and documentation on CDrom for further scientific, educational, industrial, governmental use • Task 5: to develop and document a common methodology for data and meta-data formatting and qualifying, in conformity with the internationally agreed standards. This protocol aims to be adapted to the historical data management of different data types, as well as new real time data.
Time Schedule and Data Flow Data Flow • Bench Mark 1 : test the format of national data sets • Bench Mark 2 : test the format, codes and overall coherence between regional QC centres and the global assembling centre • Bench Mark 3 : test of the bio-chemical data sets processing • Bench Marck 4 : test of the complete data set and the full processing Final processing of the complete data set • Reference protocol manual Time Schedule
Definition of a Common Protocol for data formatting, checking and processing (Task V) • Objective : to insure coherence and compatibility between data sets from various sources • Methodology : • development of existing international standards (IOC, ICES, MAST) • workshop and job training in regional intercalibrated data centres • Content • common MEDATLAS exchange format, which According to ICES/IOC should: • be autodescriptive • be independant of the computer • be flexible and accept (almost) any number of parameters • keep track of the source and history of the data • allow the processing of each profile independantly • quality checks procedure with automatic and visual checks, and quality flags as a result This protocol is now used in several Mediterranean projects
