These samples, collected across a several-thousand km transect from the North Atlantic through the Panama Canal and ending in the South Pacific yielded an extensive dataset consisting of 7.7 million sequencing reads (6.3 billion bp).
The number of interesting biological observations and novelties is lower than expected for such a giant project (Roland once mentioned this discrepancy for metagenomic studies) but there is still much potential in the data for further analyses.
Update: The video of the press conference is online now. Pedro followed it live and blogged some comments. This publication brought up again some voices questioning the (expensive) general metagenomic method. Working with this noisy data I can tell that it is often quite a pain. But to get the big image even if it would just show us we have seen already everything we have to go that way. Hopefully improving technologies - I once mentioned single-cell sequencing combined with microfluid separation systems - will make it easier for us to explore the unknown wold out there.
