The Iceland Greenland Seas Project (IGP) has added 4 datasets. These are served from contributing data centres and further information is available at https://yopp.met.no/metadata_search/?quid=3143132bf3a94052d2dfbf17cbe15fb3c0e37f26f7429a25194c21ef6cba24c61598977038.

First week of July the search interface and results tabulation was updated. The search interfaces has received

• improved support in the map search (including map projections),
• the list of institutions is made more manageable,
• all fileds are expanded by default but can be collapsed by the user,

results tabulation now includes

• a map presentation of location of datasets
• improved visualisation of time series which now includes dynamic plotting (including readout of values)
• improved data dump to CSV

The YOPP Guidance for Data Centres manual has been updated. The updated manual is available at here. Specific elements that are updated include how to link datasets hosted external to the YOPP data portal to the catalogue. Options to connect datasets that are not served through discovery metadata interoperability interfaces are described.
