Multidisciplinary, multi-investigator studies of the structure and function of ecosystems are fundamental to MEERC. The success of the Center depends on the free exchange of data and information among investigators and in mutual trust that data collected by any individual will not be used by others without the express permission of that individual. Timely submission of data for archival, attention to QAQC, access to data, and the sharing of data among investigators are vital to the research interests of all MEERC investigators.
For the purposes of this policy, data generated by MEERC investigators falls into two categories: "core" data collected as part of multi-investigator, ecosystem experiments and data collected by faculty and their students as a part of research projects funded by MEERC.
Timely Submission of Data and QAQC
"Core" data on the following variables are collected as part of multi-investigator ecosystem experiments: air temperature and relative humidity; water temperature, salinity, pH, dissolved inorganic nutrients, dissolved oxygen, particulate organic nitrogen and carbon, phytoplankton pigments, and phytoplankton abundance. These data are to be incorporated into the MEERC data base and will be available to all investigators within two months of the completion of each experiment. QAQC for these data is the responsibility of the MEERC Data Manager.
All data from measurements made specifically for projects conducted by students and faculty are the property of the individual(s) conducting the research. These individuals have the responsibility for QAQC and timely submission of data. These data will also be available to all MEERC investigators upon request.
Publication of Data
All publications and reports that use data generated as a part of projects funded by MEERC must acknowledge MEERC support. All publications and reports by students who derive their primary support from MEERC must acknowledge this support. Core data that have been approved by the MEERC Data Manager are available for publication by all MEERC investigators. Data generated as a part of research projects conducted by students and faculty are the property of the individuals who conducted the experiment or made the measurements and may not be used for publication without the permission of the responsible investigator for a period of three years following the collection of data (faculty) or following departure from the graduate program (students) for any reason (completion of degree requirements, transfer to another institution, leaving graduate school, etc.). Once the "statute of limitations" has been satisfied, data will be available to anyone on request.

The QAP component is responsible for working with MEERC investigators to insure the quality, archival, and dissemination of data in a timely fashion. P/B and S&M studies involve the use of physical (experimental ecosystems) and mathematical models to ex plore scale-dependent ecosystem responses to external forcings. Parallel projects are intended to provide information on specific processes or populations in experimental ecosystems, to explore problems that will influence the design and interpretation o f ecosystem experiments, and to develop general ecosystem models for the prediction of ecosystem behavior and evaluations of ecosystem health. In consultation with the Science Advisory Committee, the administrative component is responsible for setting MEERC priorities and goals, for funding projects that will achieve these goals in a cost-effective manner, for the coordination of these research efforts, and for insuring the timely reporting and dissemination of their findings.
