Ocean Sampling Day (OSD) is a simultaneous sampling campaign of the world’s oceans, which took place for the first time in 2014, was repeated in 2015, and again in 2018 and 2019. The OSD samples, which are related in time, space, and collected environmental parameters, provide insights into microbial diversity and function, enriching our understanding of marine biodiversity and contributing to the blue economy through the identification of ocean-derived biotechnologies. We see OSD data as a reference data set for generations of experiments.  

The Github repository for Ocean Sampling Day 2014 and 2015 can be found here. These include

• Overview and documentation for the sequencing and analysis done (2014, 2015)
• Links to raw and (partially-)processed sequence data (2014, 2015)
• Links to metagenomic analysis results (2014)
• Links to the environmental data (2014)
• Scripts used to produce some of these datasets (2014, 2015)

(A page on ODS2016 is also included in the Github repository, however very little was done and no data are provided. The 2018 and later data are provided elsewhere.)

The OSD 2014 (meta)data can also be found in Pangea, and this includes the accession numbers for the sequences archived in ENA.
