Getting Started


1.1 How do I register a username and choose a namespace?

At the homepage http://www.geosamples.org, click on the new user? button on the right hand side. You will be redirected to the GeoPass page, where you can register for an account that will give you access to SESAR as well as other EarthChem applications.


Your username is the email address with which you register. The first time that you log into SESAR, you will be prompted to choose your five-character namespace. All newly-created namespaces will begin with IE and be followed by 3 letters and/or numbers of your choosing. The namespace is not case sensitive. Common namespaces are initials or abbreviations of a large project.


1.2 How do I register my samples?

From the SESAR homepage, click the right-most option in the headerbar, LOGIN TO MYSESAR. You will see your personal SESAR page, mySESAR. Along the top of the page, you will see several tabs for navigating in your SESAR space. Click on the tab for Sample Registration.


From the Sample Registration Page, you can choose to register an individual sample or to create a batch file template. Click here for more information on Sample Registration.


1.3 How are IGSNs assigned?

After choosing to register an individual sample, you will be able to choose from two options: letting SESAR assign the IGSN, or assigning the IGSN yourself. If you choose the first option, SESAR will generate the 5-character code after your namespace (counting up in order, alphanumerically).


In a batch upload, you have the option to specify your own IGSNs into the IGSN field of the template, or leave the column blank to have them assigned by SESAR. We strongly recommend that you allow SESAR to automatically generate IGSNs for you, rather than specifying your own.


1.4 How do I set private vs public settings on my samples?

When you register your sample(s), you can now set release dates for your sample metadata. Release dates determine when sample metadata is publicly accessible and searchable. If no release dates are specified, sample metadata will be publicly accessible immediately (recommended). SESAR strongly recommends that sample metadata become available immediately upon sample registration or within two years of registration.


1.5 What metadata fields are built into SESAR?

Please see the metadata list here.


1.6 What metadata fields are mandatory?

The only mandatory metadata fields are Object Type and Sample name. We recommend filling in more metadata to take advantage of search and organization capabilities of SESAR. We recommend filling in at least Collection Method and Geolocation (Lat/Lon), as these are commonly searched fields.


Searching Samples


2.1 How do I search for samples?

The search page is accessible from the SESAR home page and from MySESAR.


If the search window is slightly shaded, it means that suggestive-search occurs for that field: Start typing and a drop-down list of possibilities will appear.

3.1 When and how do I cite samples that I use from SESAR?

IGSNs can be used in publications as a unique identifier for a sample. Readers of the publication can then use SESAR to find out more information about the sample, and find related samples.


The suggested format for citing SESAR samples is .... "IGSN: XXXXXXXXX"


3.2 What is the difference between material and object?

The Object, or Sample Type, is often related to how the sample was obtained, while the Material is the actual substance that was analyzed. Material is sometimes known as "Medium."


3.3 How are parent and sibling relationships defined?

A parent sample is a sample from which subsequent smaller samples are derived. Examples of children samples are: splits, rock powders, thin sections. Multiple parent-child relationships are allowed: (Grandchildren, Great-grandchildren.)


The parent-child relationship is NOT automatically encoded in the IGSN number because the number follows strict length rules. However, if you choose your own IGSN, you can select the alphanumeric characters in a way that has meaning to you.


Sibling samples are defined as samples with the same parent.




4.1 I submitted a batch upload template but have not heard anything. What happened?

If you uploaded a batch registration template but do not receive an email from SESAR confirming the registration after a few days, please contact info@geosamples.org with your name and namespace.


4.2 How do I submit a comment or bug notification?

Please submit all comments or bug notifications to info@geosamples.org.
