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 and
event indexing promotes standard conventions
establishes relationships between diverse data
efforts at the time of collection. The event
logger addresses issues of time, space and
categorization using standard vocabulary in order
to assist subsequent data integration and
exchange. It becomes one element of an
information infrastructure that contributes to
creating a common dataspace (Franklin et al,
2005), both conceptual and physical, that
stretches from field to land and back again.
Bridge Activities
Digital practices from data collection to data
preservation are supported by Information
Infrastructure. Infrastructure-building draws on
the fields of informatics, information systems,
science and technology studies, library and
information sciences as well as infrastructure
studies. At SIO, an Ocean Informatics environment
supports the design, development, deployment, and
enactment of effective data practices as part of
community infrastructure-building (Baker et al,
2006).
Design and Use
Purpose
- 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 and 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.
Event Number
- Design theory and 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 and
controlled vocabulary list-use. This facilitates
a collective understanding of data and its
organizing in addition to ensuring that data are
well represented and integrated within the data
community. Event Logger features include - Configuration files to create local flexibility
required for varying ship platforms and group
interests - Authoritative lists of shared vocabulary
established to accommodate changing vocabulary
and maintainability as well as to contribute to
sociotechnical process-building - Event numbers enmeshed in field practices that
travel from sea to land as a data index
incorporated into the architecture of the
information system

Cruise Event Log
Methods
- 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 - standalone Windows pc with GPS
- networked multiple Windows pcs with GPS on
one and a mapped network directory
