Alred, John, Managing Editor has reference to this Academic Journal, PHwiki organized this Journal An Oceanographic Event Logger James R. Wilkinson in addition to Karen S. Baker Scripps Institution of Oceanography, University of Cali as long as nia San Diego Field Practices Purpose Methods In as long as mation Infrastructure Design in addition to Use Event Logger System = Event Logger(s) + Event Number + GPS => Event Log Event Number 20060511:234530 32.865 -117.253 GPS Timestamp An oceanographic event logger, recently deployed on CalCOFI research cruises, extends data coordination into the data collection arena. The event logger system consisting of networked PCs, communal event log, GPS coordinates in addition to event indexing promotes st in addition to ard conventions & establishes relationships between diverse data ef as long as ts at the time of collection. The event logger addresses issues of time, space in addition to categorization using st in addition to ard vocabulary in order to assist subsequent data integration in addition to exchange. It becomes one element of an in as long as mation infrastructure that contributes to creating a common dataspace (Franklin et al, 2005), both conceptual in addition to physical, that stretches from field to l in addition to in addition to back again. Project-specific data management must support data community coordination. By using the event logging system throughout the ship, all cruise participants, on any workstation, are able to: contribute uniquely indexed events to the cruise event log. establish a common coordinate system to log all samples from shared activities, such as rosette sampling, using the event index in addition to its ship-based GPS date, time, latitude & longitude. relationally link diverse data products from shared events post-cruise using the index as a relational database identifier. correlate continuous data, such that weather, acoustics, or sea-surface temperature measurement, to individual or grouped events using the common coordinate system. Digital practices from data collection to data preservation are supported by In as long as mation Infrastructure. Infrastructure-building draws on the fields of in as long as matics, in as long as mation systems, science in addition to technology studies, library in addition to in as long as mation sciences as well as infrastructure studies. At SIO, an Ocean In as long as matics environment supports the design, development, deployment, in addition to enactment of effective data practices as part of community infrastructure-building (Baker et al, 2006). Design theory in addition to classification analysis are playing an active role in the iterative development of the CalCOFI Event Logger (Lindseth & Baker, 2006). Our methodology enables interplay of shared vocabulary-building in addition to controlled vocabulary list-use. This facilitates a collective underst in addition to ing of data in addition to its organizing in addition to ensuring that data are well represented in addition to integrated within the data community. Event Logger features include: Configuration files to create local flexibility required as long as varying ship plat as long as ms in addition to group interests Authoritative lists of shared vocabulary established to accommodate changing vocabulary in addition to maintainability as well as to contribute to sociotechnical process-building Event numbers enmeshed in field practices that travel from sea to l in addition to as a data index incorporated into the architecture of the in as long as mation system Acknowledgements We would like to thank the Ocean In as long as matics participants who are designing as long as the long-term, the field participants – ship in addition to scientific staff – who are enacting the system, as well as the community participants who are co-constructing the system. In particular we recognize the work of Robert Thombley, Shonna Dovel, in addition to Jessie Powell. This work has been supported by NOAA CalCOFI in addition to NSF Long-Term Ecological Research in addition to Human Social Dynamics Programs.

Cruise Event Log Bridge Activities Installation of the event log software on individual, networked Windows workstations enables local, project-specific activities lists (main figure). Each workstation polls common GPS & event number files, incrementing the value when an event is recorded. A cruise log tabulates all logged events. Each workstation also generates a separate project-specific activities log. Current requirements: st in addition to alone: Windows pc with GPS networked: multiple Windows pcs with GPS on one in addition to a mapped network directory A FIELD PERSPECTIVE A DATA STEWARDSHIP PERSPECTIVE
