Information Management


The California Current Ecosystem LTER Information Management (IM) component provides core data and information management services in addition to supporting various scientific, outreach and LTER network needs through the continued development of a comprehensive information management environment. Our primary goals include (1) providing well documented, quality data to the public in a timely manner, (2) continuing to develop a data system that provides effective access to core site and related data, (3) providing support for site science through flexible and innovative data product development and access and (4) maintaining a data and information management that ensures long-term stability and integrity.

Submitting Data

Data that are collected or produced with full or partial funding provided by the CCE LTER project are required to be archived and made publicly available. If you have collected data aboard a CCE LTER process cruise, or through other assistance from the project, please visit the Submitting Data section for information, guidance and metadata forms.

Data Availability

The primary data access and catalog system for CCE is Datazoo.  Built using open source technology (MySQL, PHP, Apache, JavaScript) Datazoo provides an integrated data access and documentation system for all of CCE’s core data. Datazoo’s relational model supports the current LTER standards and best practices and integrates the LTER Controlled Vocabulary and Unit Registry NIS (Network Information System) components to support standardized search terms and scientific units across network sites.  Datasets from Datazoo are currently being published to the LTER network archive (PASTA) using Ecological Metadata Language (EML 2.1.1). Datazoo supports finding datasets via queries utilizing full-text indexing and weighting across a number of metadata elements, in addition to an intuitive faceted search interface that supports project-specific categories for data organization.  Datasets can be queried, previewed, plotted and downloaded (CSV, Excel) through Datazoo’s interface. Both the data querying and data plotting functions of Datazoo were built as modular system components that support generalized offline processing for producing large data results and a variety of plots.

Additional systemsFileFinder is an application for indexing large and more complex file collections and provides an interface for searching, packaging and downloading data.  FileFinder permits access to CCE’s processed Moving Vessel Profiler (MVP) data.  In addition, the Cooperative Zooplankton Dataspace is home to two applications for querying, plotting and downloading data from two extensive zooplankton and euphausiid collections, ZooDB and the Brinton and Townsend Euphausiid Database (BTEDB), in addition to the SIO Pelagic Invertebrates Collection and other resources pertinent to marine zooplankton.

Data Policies

Data Use

The data available here are intended for scholarly use by the research community, with the express understanding that data users will properly acknowledge the originating investigator. Use or reproduction of any material herein for any commercial purpose is prohibited without prior written permission from the responsible party.

Data Acknowledgment

Data from  CCE LTER data systems were supported by NSF Grants NSF/OCE-04-17616 and NSF/OCE-10-26607.

Data Availability

Our goal is to release the long-term datasets associated with core research within 2 years of collection. Data together with their metadata will be available for download from our website. Other datasets relating to site research are prioritized and released as support permits.
