Animal telemetry data are subject to acute data interoperability issue stemming from their characteristic paucity of file level metadata combined with the prevalence of ad hoc file formats. To address these issues, members of the COVERAGE team have been involved in a collaborative effort with UCAR-Unidata and LPRC UMASS-Boston to develop a standards-based netCDF template specification for electronic tagging instrument data files. The nc-eTAG v1.0 specification was publicly released and announced in January 2020. This technical document is available at https://doi.org/10.6084/m9.figshare.10159820 and is accompanied by associated netCDF CDL templates and some related materials available via https://doi.org/10.6084/m9.figshare.10055603. These resources provide detailed guidance on how the range of key tagging data class types can be encoded consistent with prevailing Earth Science data interoperability conventions (nc, CF, ACDD) to produce archive quality, standards compliant data files. The nc-eTAG specification was presented during a recent ESIP Marine Data Cluster webinar session, the recording of which is available here.
A demonstration video highlighting the range of COVERAGE inter-agency satellite and in-situ data sets displayed within the project’s advanced Web-based visualization tool was release on 4/13/20. Remote sensing data for various parameters are integrated and shown in relation to Atlantic Bluefin tuna, marine turtle, and bird animal telemetry data, AIS fishing vessel data, and commercial fishery spatial catch/effort series for a range of large pelagic species. Stunning movements of these organisms both horizontally and vertically through the water column as they track environmental features are displayed through this highly interactive and intuitive visualization tool. Visual exploratory analysis of the integrated, rich data layers enable the generation of hypotheses on the role of environmental seascapes, fishery activity and individual animal behavior on population level structure and dynamics.
The COVERAGE project’s perspective on approaches, technologies and considerations for integrated Web-based visualization of multi-variate ocean data was presented by Dr. Vardis Tsontos as part of a panel discussion at the Visualization Data Fair session organized by the ESIP-Federation. Panelists at this packed session included representatives from NOAA, UCSD/SIO, and JPL/COVERAGE. Discussions emphasized the need for:
- Capabilities support the spectrum of different spatial data types, ranging form gridded, vector, and discrete sampling geometry (point, profile, trajectory, time series) representations
- Consideration of not only fronted-client tolls but the importance in particular of back-end data provisioning services enabling visualization frameworks
A spirited and productive conversation ensued between the audience and panelists in the Q&A session that followed.
The COVERAGE project’s state-of-the-art Web-based data visualization tool was presented during two NASA Hyperwall sessions at the Ocean Sciences 2020 conference on 2/19 by Dr. Vardis Tsontos to a very favorable reception. Integrated visualization of oceanographic data of various types was demonstrated. These included satellite imagery for mutliple parameters, animal telemetry, research cruise, saildrone, and other in-situ data. The power of the tool for exploratory visual data analysis via this elegant and intuitive user interface was emphasized.
The COVERAGE team held a successful first consultative workshop to introduce the project and demonstrate some prototype capabilities at OSM20 on 2/18/2020. Attendees included representatives from ABOM, IOOS-MBON, IOOS-ATN, USGS, Axiom Data Science , USF, Texas A&M, Ocean Data Lab, RPS Group. We appreciate the participation of the colleagues and the positive, helpful comments received.
COVERAGE Team Kick-Off meeting
The COVERAGE Phase-B project (prototype development) officially began on in early October, 2019 with NASA support.
The COVERAGE team, based at the NASA Jet Propulsion Laboratory, held a project kick-off meeting on 9/30 to discuss the work and plan next steps.
