About VentDB

1.1 What kinds of data can I obtain through VentDB?

VentDB provides access to analytical data of chemical and physical properties of seafloor hydrothermal springs. The Search application allows you to extract customized datasets with your selection of analyzed parameters and samples. This is a proto-type of the data system with a limited amount of data, but new data is continuously being added. The analytical values are complemented by associated metadata (commonly defined as data about data), providing information on how the data was obtained, including information about the sample, analytical method, flow type, literature reference, and geographic location.
 

1.2 How do I know these data are reliable?

VentDB will contain data that have appeared in the public record, including journal articles, monographs, ODP briefs, masters and doctoral theses or tables have been submitted directly to us in supplemental format (e.g. data tables providing raw data for figures). VentDB cannot guarantee the accuracy of reported data beyond peer review at the publication and committee level. We strongly urge users to use the same level of critical judgment as they would with any other kind of published data.
 

1.3 Where can I get more information about parameters and sampling devices used in VentDB?

A description of several parameters, sampling devices, and other information is at www.ventdb.org/help/moreinfo

 

Basic Searches and Functions

2.1 How do I query for End-member data?

  • Select: Sample Characteristics>By Sampling Technique>Calculated>Apply>Continue to data Selection> Select Items>Submit.
or
  • Select: Sample Characteristics>By Material Type>Fluid>end-member>Add>Apply>Continue to data Selection> Select Items>Submit.

2.2 How do I query for geographically specific data?

e.g. I want all data from the Juan de Fuca Ridge.
There are several ways to do this, the simplest is to select:
  • Use the GEOGRAPHICAL NAME filter. Select SPREADING_CENTER>JUAN DE FUCA RIDGE>Add>Apply>Continue to data Selection> Select Items>Submit. Results will be displayed in a data table that can easily be downloaded to your desktop.
or
  • Use the LATITUDE/LONGITUDE filter to define a bounding box for the JdF. Click SET Latitude/Longitude> Enter: 48N, 42S, -133W, -129E>Apply>Continue to data Selection> Select Items>Submit.

2.3 How do I query by flow type?

e.g. I want data from black smokers only.
  • Click “Sample Characteristics”>By Flow Type>scroll down to “focused_flow:black_smoker>apply>Continue to data Selection> Select Items>Submit.

2.4 How do I query by sampling device?

  • Select: Sample Characteristics>By Sampling Technique>Sampler:Fluid:GasTight>Apply>Continue to data Selection> Select Items>Submit.

2.5 How do I query by vent or vent field?

  • For a Vent: Geographical Name> Vent>KM2>Add>Apply>Continue to data Selection> Select Items>Submit.
  • For a Vent Field: Geographical Name> Vent_Field>KILO MOANA>Add>Apply>Continue to data Selection> Select Items>Submit.

2.6 How do I check method metadata and reliability?

  • Follow any of the paths above e.g. Click “Sample Characteristics”>By Flow Type>scroll down to “focused_flow:black_smoker>apply>Continue to data Selection> Select Items>Submit.
  • Click on any chemical value in the data table and a pop-up will display method-relevant metadata.
