Coastal CarbonData Clearinghouse

Coastal Carbon Data Clearinghouse



Data Management Plan (Version 1)

The CCRCN strives for transparency with methods of data archival and management. Here we overview data types and structure associated with the Network, and procedures for data storage and quality control.

Database Structure (Version 1)

An exhaustive description of the naming convention for attributes and variables recommended by the CCRCN.

Coastal Carbon Atlas

Data Products

The Network recognizes three classes of data: (i) data that we curate, (ii) data that we ingest, and (iii) synthesis products we create. Data that we curate will be hosted on Smithsonian Institution (SI) servers, but the original data submitter and funding sources will be credited as the dataset’s creators. Data that we ingest will include both data we curate and data from any outside sources that meet basic availability, archiving, and metadata standards.

See below for a list of CCRCN data products.

Testimonials to Data Contribution


“The Coastal Carbon Research Coordination Network dataset has been invaluable in our recent research identifying global drivers of variability in coastal wetland carbon cycling. The Network’s dataset greatly complemented our own previous data collation efforts, filling important gaps in our record. The availability of a comprehensive and well-curated dataset allowed us to focus on the analysis and interpretation of data, deriving important new insights in global patterns of carbon storage.”

- Jeffrey Kelleway, Department of Environmental Sciences, Macquarie University

"The CCRCN database is a key cornerstone in accelerating the pace of discovery for coastal carbon cycling.  I recently downloaded version 1, and have begun analylzing it and intercomparing its features with other national and global sets on soil core characteristics. As it focuses only on soilcores from tidal wetland, it is the single largest and spatially explicit empirical dataset, globally, for populating carbon stock assessments or testing models across space and time. For coastal lands, it is an invaulable asset for scientists and managers alike.  The developers of the dataset and platform should be commended, as should the many community contributors who are fueling advances in science and practice by sharing their data."

"[The CCRCN administrators] are doing an amazing job at this organization and promoting inclusivity. I am floored by your intuition and abilities. You are the natural heirs to this community-building."

- Lisamarie Windham-Myers, U.S. Geological Survey
