Meeting 8 November 2013, 14:30 pm

Google Hangout

Present: GP, Lino, Fabrice, Edward

Notes

Use Case document was produced by Edward, and available from http://goo.gl/fxVbtv. It will be placed on the wiki and integrated with the other pages on Environmental Data Enrichment.

Fabrice introduced us to the work Terradue has done with OGC Observations and Measurements (O&M - http://en.wikipedia.org/wiki/Observations_and_Measurements), and with the SOS service (http://en.wikipedia.org/wiki/Sensor_Observation_Service and http://blog.52north.org/2013/10/18/sos-4-0-0-rc1-released/). There is some expertise within Terradue for O&M. SOS was identified as a good candidate to be used as a service; it would take Terradue roughly 1 month to deploy SOS. We will all have a closer look at the information available through the links, and have an informed discussion on the use of O&M and SOS in our next meeting, in two weeks' time.

We'll start experimenting with extracting SST and Chlorophyll data, as suggested by Julien during last meeting. Also bathymetry would be easy to make available; we'll also check again what bottom data are available from GOLD (Global Ocean Life Distribution, see also http://www.grida.no/marine/news.aspx?id=5290 and http://geoiq.grida.no/maps/1136). Terradue will explore extra parameters that are low-hanging fruit. Edward will investigate the potential of some species of Pteropoda (pelagic molluscs) as candidates for an exercise in data enrichment, and feeding into the earlier suggested use cases on Species Data Modelling/Environmental Envelope Modelling (see http://wiki.i-marine.eu/index.php/Environmental_Data_Enrichment and http://wiki.i-marine.eu/index.php/Calcifiers).

A first exercise would be to extract data for the same parameter from different sources, and compare the holdings of these sources.

Lino will make one machine available to Terradue for this activity; Fabrice will pass specifications.

Extracting data using O&M and SOS is the first step in the process; we'll still have to do the step of interpolation. The idea is to build experience with extracting data, and to familiarise ourselves with the data coming out of these extractions. This will make our planned conversation with NODC folk on interpolation more concrete. We're only looking at surface or bottom data right now, so we miss the 'fourth dimension' of the water column; we'll deal with this later on.
