By using OBIS data, I agree that, in any publication or presentation
of any sort based wholly or in part on such data, I will:

1. Acknowledge the use of specific records from contributing databases
in the form appearing in the GLOBAL 'citation' attribute thereof (if any);
and acknowledge the use of the OBIS facility in one of the following
prescribed forms:

For OBIS website:

Ocean Biogeographic Information System. [date accessed]
http://iobis.marine.rutgers.edu/digir2/DiGIR.php

For data used:

Example:

2. For information purposes, provide to nwolff@usm.maine.edu
the full citation of any publication I make (printed or electronic)
that cites OBIS or any constituent part.

3. Recognize the limitations of data in OBIS:
OBIS is comparable to a scientific journal that makes data freely
available on the internet. Thus the geographic and taxonomic scope,
and quantity of data provided, depend on the scientists and
organizations that provide data. However, in contrast to data in a
journal, the 'reader' can select and combine data in OBIS from a
variety of sources. OBIS and its users give feedback on data quality
and possible errors to data providers. Because data providers are
willing to correct errors, the quality of the data will increase in
time. How OBIS provides quality assurance, who is primarily
responsible for data published in OBIS (its owners), issues to be
considered in using the data, and known gaps in the data, are
described below.

Quality assurance

Only data from authoritative scientists and science organizations
approved by OBIS are served. All data are subject to quality control
procedures before publication, and at regular intervals, with data
providers informed of any discrepancies and potential errors (e.g.
species names spelt incorrectly, mapping errors). OBIS also benefits
from user peer-review and feedback to identify technical, geographic,
and taxonomic errors in data served. However, although errors will
exist as they do in any publication, OBIS is confident that the data
are the best available in electronic form. That said, the user needs
sufficient knowledge to judge the appropriate use of the data, i.e.
for what purpose it is fit.

Many of the data published through OBIS have voucher specimens in
institutional collections and museums, images of observations, and
the original identifier of the specimens is often credited or will
be contactable from the data custodian.

Data ownership

Data providers retain ownership of the data provided. OBIS does not
own or control or limit the use of any data or products accessible
through its website. Accordingly, it does not take responsibility
for the quality of such data or products, or the use that people may
make of them.

Data use

Appropriate caution is necessary in the interpretation of results
derived from OBIS. Users must recognize that the analysis and
interpretation of data require background knowledge and expertise
about marine biodiversity (including ecosystems and taxonomy).
Users should be aware of possible errors, including in the use of
species names, geo-referencing, data handling, and mapping. They
should cross-check their results for possible errors, and qualify
their interpretation of any results accordingly.

Users should be aware that OBIS is a gateway to a system of databases
distributed around the world. More information on OBIS data is
available from the data sources websites and contact persons. Users
should email any questions concerning OBIS data or tools (e.g. maps)
to the appropriate contact person and copy this request to
nwolff@usm.maine.edu .

Data gaps

Major gaps in data and knowledge about the oceans are reflected in
OBIS' data coverage. Note the following:
Most of the planet is more than 1 km under water: this deep sea is
the least surveyed part of our world.
Coastal areas have been adequately sampled only for the distribution
of most vertebrates (birds, mammals, reptiles, larger fish).
The oceans have been better sampled in the northern than the
southern hemisphere, as reflected in the distribution of data in
OBIS.
Most marine species have not yet been recognized or named. A major
effort is required to describe marine species, especially
invertebrates and deep-sea organisms.
Of the marine species that have been described, some have been
discovered to be several species, and others combined into single
species. Thus, there are changes in the application of species names
over time. A checklist of all current marine species names is not
available but it is estimated that 230,000 have been described.
Only about half of these names have been organized into global
species checklists. OBIS includes distribution data on (a) many of
these validated names and (b) additional names that remain to be
organized into global species checklists. Thus, OBIS has some
distribution data for about one third of the known marine species.
Some species distribution data are not available in any form, as
they have not have been published nor made available for databases.
Only some of the recently collected, and less of the older published,
data have been entered into databases. Thus databases are incomplete.
Of existing databases, many are not connected to OBIS.

You can help address these data gaps by (a) recognizing and
encouraging scientists and organizations to make their data available
online so they are accessible to OBIS, and (b) advocating for and
carrying out field surveys and taxonomic studies designed to fill
geographic and taxonomic gaps in knowledge.

DiGIR is an engine which takes XML requests for data and returns a data
subset stored as XML data (as defined in a schema). For more DiGIR
information, see http://digir.sourceforge.net/ ,
http://diveintodigir.ecoforge.net/draft/digirdive.html ,
and http://digir.net/prov/prov_manual.html .
A list of Digir providers is at
http://bigdig.ecoforge.net/wiki/SchemaStatus .

Darwin is the original schema for use with the DiGIR engine.

The Ocean Biogeographic Information System (OBIS) schema extends
Darwin. For more OBIS info, see http://www.iobis.org .

Queries: Although OBIS datasets have many variables, most variables
have few values.  The only queries that are likely to succeed MUST
include a constraint for Genus= and MAY include constraints for
Species=, longitude, latitude, and time.

Most OBIS datasets return a maximum of 1000 rows of data per request.
The limitation is imposed by the OBIS administrators.

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.

Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names, followed by a collection of constraints (e.g., variable<value), each preceded by '&' (which is interpreted as "AND").

For details, see the tabledap Documentation.
