Revisions allow you to track differences between multiple versions of your content, and revert back to older versions.
Overview:
The Ocean Biogeographical Information System is a catalog of global marine species inventory. The data is reported through interactive mapping software from which you can extract summary and point data.
Dataset Location: OBIS; OBIS-Spatial Ecological Analysis of Megavertebrate Populations
Site Location: Global
Site(s) Georeferenced: Yes
Timespan: 1800s - Present; large focus for 2000-2010 Census of Marine Life
Data collected: OBIS presents data from a number of layers, including layers with species enenvironmental information and others for map visualization. A complete list of layers can be found at - http://www.iobis.org/geoserver/web/.
Data layers include:
drs_with_woa - species observations are linked with the World Ocean Atlas 2005 environmental data; species name, individual count, date, location, temperature, depth, salinity, nitrogen, oxygen, silicate.
points_ex - species observations include expanded collection info acquired from the original provider record
grid_sp - gridded species distributions
summaries - gridded biodiversity (Simpson, Shannon, ES50), number of observations, number of taxa per c-square cell
Known Issues: The OBIS and OBIS-SEAMAP systems provide some barriers to automated or expansive use of the data.
There are a number of steps to access data in the OBIS GUI, including: identifying taxa and/or specific datasets within the catalog, navigating to the show results panel, and specifying download options. The OBIS-SEAMAP requires you to contact the data contributor for acces to their data.
