The registration facilitates the access decision process:
You have a Marine ID identifier but you have not accepted SeaDataNet license agreement.
Please go to the SeaDataNet data portal and proceed to the following steps:
The result of your search will show-up after a while (depending on your criteria for selection)
Please feel free to contact us if you have any problem using the SeaDataNet web portal for data downloading.
No, all data are not unrestricted and free for use.
The general case is free an open access for data, around 85% of the data are accessible. Once the user is registered and have agreed with the “SeaDataNet user Licence”, he can, by default access all data which are unrestricted or under SeaDataNet licence.
Then depending on his status, organisation…. The SeaDataNet node responsible of the user's country country will attribute him a specific role which can give him access to more restricted data.
Data Access restriction
% of the SDN dataset (Feb 2015)
The data are freely available to anybody and may be used for any purpose. Usage acknowledgement may be required.
Access to the data and usage are as specified in the SeaDataNet data policy and licence agreement
The data are withheld from general circulation and disclosure but access may be obtained on a case-by-case basis through negotiation.
The data are freely available for research and education purposes. Usage acknowledgement is usually expected.
The data are unrestricted to members of an organisation or a virtual organisation (such as project or cruise participants) but restricted to anybody else.
Access to the data cannot be negotiated.
Data are initially restricted, but the access condition relaxes to academic or unrestricted once a specified period of time after an event (such as collection, publication, completion of QC procedures or project cessation) has elapsed.
Conditions of supply and usage of the data are specified in a formal agreement.
A charge significantly exceeding the cost of data collection and delivery is made for usage of the data.

Data were provided through SeaDataNet Pan-European infrastructure for ocean and marine data management (http://www.seadatanet.org)
A record is an XML metadata document conforming to a named SeaDataNet schema describing a particular type of SeaDataNet data entity.
A meaningful collection of measurements. 'Meaningful' can have infinite different meanings that must be constrained through the definition of specific types of dataset used within the SeaDataNet data model. The following dataset types are in use:
This is the fundamental atomic entity in the SeaDataNet data model and is an aggregation of measurements or observations. It is mapped to real world measurement aggregations in different ways such that the dataset is meaningful for a specific type of data, such as a CTD profile or the time series from a single deployment of a data logger. It is described by a CDI record that is permanently associated in the SeaDataNet architecture with one or more physical data files.
This is the aggregation of CDI datasets from the activity described by a Cruise Summary Report (CSR) record.
This is the aggregation of CDI datasets from a discoverable activity described by a European Directory of Marine Environmental Datasets (EDMED) record.
This is the aggregation of CDI from a monitoring activity described by an EDIOS series record. This is the atomic level of monitoring activity such as a station within a programme.
This is the aggregation of a set of related EDIOS datasets and is described by an EDIOS programme record. Note that an EDIOS programme dataset may also be considered to be a discoverable activity and additionally described by an EDMED record.
This is the aggregation of the CDI datasets from an activity described by a European Directory of Marine Environmental Research Projects (EDMERP) record.
This is an aggregation of CDI datasets that provide the input for a SeaDataNet or EMODNET data product, such as a climatology or location time series. The aggregation will be usually be specified in terms of spatio-temporal limits and one or more observable properties (parameters).
This is a CDI aggregation guaranteed free from future change that is citable through a URN such as a Digital Object Identifier (DOI).
This is the aggregation of CDI data granules having a common data discovery parameter keyword supplied by a single data originator. It is the dataset presented to the GI-Cat brokering service.
This is the aggregation of all the CDI datasets in the SeaDataNet system.
Each user connected to SeaDataNet infrastructure (i.e which received a specific login/password) has a role which is by default ‘Public’ and which can be changed by the SeaDataNet node managing the user directory of his/her country to the available roles:
A user who is able to bypass any access control created by SeaDataNet but with no bypass rights for local access controls.
Any authenticated individual with sufficient credentials to satisfy SeaDataNet access logging requirements.
A user who accesses data on the SeaDataNet network for purposes of education or bona fide non-profit academic research.
A user who accesses data on the SeaDataNet network with the objective of making a financial profit from its use.
National and local government
A user who accesses data on the SeaDataNet network for administrative or legislative purposes within the boundaries of a nation.
A user who accesses data on the SeaDataNet network for international administrative or legislative purposes. Generally, but not exclusively, the European Union in the SeaDataNet context
A person employed by an organisation participating in SeaDataNet. This gives the right to access, create and (with ownership rights) maintain project documents and metadatabase entries.
Cruise Summary Report contributor
An individual outside SeaDataNet granted rights to create and (with ownership rights) maintain records in the SeaDataNet Cruise Summary Report repository.
One user may have several roles.
The combination of the user role and access label on one CDI determines ‘Access OK’, ‘Access to be discussed‘ or ‘Access denied’ to the data.
Each aggregated products has a DOI and can be cited as following:
Some SeaDataNet climatologies have a DOI and can be cited as following:
SeaDatanet ODV is more restrictive than ODV, some files can be uploaded in ODV, but they are not SeaDataNet ODV compliant. The SeaDatanet ODV must follow strictly the format specifications defined in the Transport format document.
Check that you have no extra 'tabulation' characters at the end of your data lines in the ODV file.
When converting the file, OCTOPUS needs to identify which type of file is your ODV input file.
The SeaDataNet ODV files can be of 3 different types : Vertical Profile, trajectory or time series. The characteristics of these types are in the document format on pages 7-8 and summarized below:
Vertical profile: a file with primary variable = Z-coordinate increasing and date and time constant = to the date and time of the start of measurement
Time series: a file with a primary variable = TIME, increasing
Trajectory: a file with primary variable = Z-coordinate, and rows are ordered by increasing time (constant date on 2 consecutive lines are detected as errors)
For a timeseries, Depth is not mandatory, but if it exists in the file it must be constant for all the duration of the time series.
If Depth varies in your measurements, you have to add another constant P01 parameter (depending of P02:AHGT) like for example: MAXWDIST, Maximum depth below surface of the water body.
