Observations and Data
NorEMSO aims to deliver high-quality water column observations in the Nordic Seas.
Main content
The fundamental purpose of NorEMSO is the long-term production of high-quality observational data, which are fully integrated into the EMSO ERIC by establishing an operational data flow. A data management and implementation plan will ensure curation, preservation and sustainability.
By adhering to the Open Research Data Pilot under the H2020 of the European Commission and the FAIR data management principles following the 鈥榞old鈥� standard, the NorEMSO data management plan also ensures free and open access to all metadata and data (NRT and delayed mode) and results generated.

Data management
Data and metadata management听of Slocum gliders
听
Mission听metadata are submitted听OceanGliders听() following听the听JCOMMOPS metadata requirements.听听
A Slocum glider log full resolution data internally but a subset of this data at a 60s interval is sent from the glider each time it surfaces (every 1-3hrs).听This reduced data from the flight and science data files are sent from the glider via听Iridium to a听data hosting听service through听Teledyne Webb.听The data听are听transferred to UIB servers听and pulled by听the Norwegian Marine Data Centre at the Institute of Marine Research in Bergen,听where near-real-time听(NRT)听processing听is performed to听produce data files in听Everyone's Gliding Observatories (EGO,听)听format. The EGO gliders听NetCDF听format ()听is听based on the听Climate and Forecast (CF) specification.听NRT data are听then pushed听daily听to the听Coriolis听data portal (), where the data are stored.听Data is also delivered on GTS through the Norwegian Meteorological Institution.听These NRT听data听are听open access with CC BY 4.0听(Creative听Commons听Attribution听4.0鈥疘nternational)听license and听are听also used for听assimilating in operational models.听Coriolis coordinates the听MyOcean听in-situ Thematic Assembly Center and provides in-situ data needed to constrain and validate the听MyOcean听global and regional Modelling and Forecasting Centers听(so-called COPERNICUS Marine Core Service).听听
Once a glider is recovered听the completed mission is reported to JCOMMOPS. The post-processing of the glider听data听is typically听finalized听within 6 months听after the mission ended. The quality control, the final product (so-called Delayed Mode data) are then submitted to听the Norwegian Marine Data Centre听() in听open access with CC BY 4.0 license, where it is stored and听uniquely听identified with a DOI.听Overall,听we aim to follow听the听FAIR data鈥痬anagement听principles听following听the听鈥榞old鈥� standard.

Slocum with听Microrider
听
The science sampling strategy is flexible and will depend on deployment duration but a likely regime would be听CTD: sampling 4s interval on dive and climb.听
Microrider: default rate of 512Hz for fast sensors. Sampling during dive, then dive and climb in key areas, possibly turned off during the last leg.听 听
A subset of this data at a 60s interval is sent from the glider each time it surfaces (1-3hrs), note turbulence data is averaged and only useful for indicating the health of the instrument. Flight and science data files (sbd听and听tbd听respectively) are sent from the glider via iridium (both RUDICS and PSTN) to a server hosting the glider piloting application SFMC.听
Data is transferred from SFMC to UIB servers where near real-time processing produces data files in EGO format which is then pushed to the open-access Coriolis platform.听
