Advanced services
The validated and aggregated buffers of data sets are input for the products and advanced services:
Interpolated maps as produced with DIVA software
Time series graphics for all collected data sets via WPS (Deltares)
OceanBrowser viewer (Ulg) as common service for viewing the DIVA maps and giving access to the time series graphics
Sextant catalogue (Ifremer) to document all products with metadata

Circles show data location (within depth and time range)
Circle are semi-transparent (intensity of a color gives an indication of number of observation points)

Plot of data at selected location as Time Series
Clicking on a circle Time series plots
(x-axis: time; y-axis: parameter)
Depth is represented by color

One can switch
between time series and profile view
For profiles(x-axis: parameter
and; y-axis: depth) Time is represented
by color
