For many years, the emphasis of data management within CalCOFI was to quality control and curate the individual datasets collected on CalCOFI cruises, and make them available to researchers and fisheries managers through printed reports and requests for data to the data curators. Today, a new goal is emerging of having CalCOFI datasets available online and, eventually, interoperable with other CalCOFI-related datasets and the larger, developing federation of the Ocean Observing System data. In this document we review the current state of data management within three of the primary CalCOFI datasets (hydrographic, ichthyoplankton, and zooplankton) and then make recommendations for moving towards the integrated online system that is envisioned, including expanding to other data types. Concrete recommendations for moving forward are summarized in Table 1 and explained in more detail throughout the text. Acknowledgements We give thanks to Rich Charter, Ralf Goericke, John Hunter, Mati Kahru, Mark Ohman, Jesse Powell, Elizabeth Venrick, Jerry Wanetick, and Jim Wilkinson for their contributions and to the CalCOFI community for supporting this work.

Introduction The purpose of this document is to overview the current state of data management within the California Cooperative Ocean Fisheries Investigations (CalCOFI) program and outline steps and recommendations for building towards an integrated, online information system for CalCOFI. It will also include consideration of how this effort could be scaled up to contribute to the emerging Pacific Coast Ocean Observing System (PaCOOS). CalCOFI is a long-term sampling program aimed at understanding the marine environment off southern California and improving living resource management in the region. It represents a consortium of the NOAA/NMFS Fisheries Resource Division of the Southwest Fisheries Science Center (SWFSC), the California Department of Fish and Game, and the Integrative Oceanographic Division (IOD) of Scripps Institution of Oceanography (SIO). A number of journal articles provide an introduction to the CalCOFI program (e.g. Ohman and Venrick, 2003; Bograd et al, 2003; Hewitt, 1988; CalCOFI, 1989, 1999) and demonstrate integrative uses of the data to address particular scientific questions (e.g. Deep Sea Research, 2003; McGowan et al, 1998; Roemmich and McGowan, 1995). The core of CalCOFI is the regular sampling: 4 times per year research vessels visit a standardized grid of 66 stations to measure physical, chemical, biological, and meteorological properties of the California Current ecosystem including censuses of organisms from phytoplankton to birds. Though the spatial and temporal scope has varied through time, this program has persisted since its inception in 1949. A program of this scope creates an enormous volume of heterogeneous data that can be valuable to a wide variety of oceanographic research and resource management applications. A recent interest in making the full range of data readily available online has led to an effort to understand holistically the current state of data management of CalCOFI data and lay a path towards building an integrated online access system. A second driver for recent CalCOFI data management interest comes from the emerging array of efforts with which to partner. Figure 1 shows some of the developing local, national, and international ocean data projects relevant to CalCOFI. In the United States, one of the larger efforts, the Integrated Ocean Observing System (IOOS),1 is in the early stages of development. The goal of IOOS is to create a unified and cost-effective approach for providing data needed to meet the suite of ocean-related challenges
