International collaboration for magnetotelluric data and model sharing and interoperability
Abstract
We discuss emerging international collaborations that promote sharing of magnetotelluric (MT) data and models and interoperability of services provided by various national projects. Each of these projects aims to serve their data to the public in a self-descripting, well-documented, efficient and searchable manner. To that end, data formats and archiving strategies are being developed. International collaboration and convergence on metadata content and archiving strategies will allow interoperability between their respective formats and databases, to ensure a smooth data interaction experience for the user. Strategies involve common or consistent metadata models, mirroring of each other's servers, development of format conversion tools, and other pathways to ensure enhanced backup and accessibility of international data.
In Europe, the European Plate Observing System (EPOS) is a Research Infrastructure through which science communities will make data and services available. Data provided through EPOS will conform to common standards and be available from a single portal, to support cross-disciplinary research. This includes MT data and conductivity models. Luleå University of Technology is responsible for implementation of MT Data And MOdels (MTDAMO) service within EPOS. The Geophysical Instrument Pool Potsdam, Germany (GIPP) Experiment and Data Archive is the platform for long-term archiving of geophysical experiment data. In the United States, EarthScope MT (2006-2018) is a program of the National Science Foundation (NSF), led by Oregon State University (OSU). Collaboration between OSU and the U.S. Geological Survey generated the first open database of searchable MT data (http://ds.iris.edu/spud/emtf). NSF's EarthCube is an ongoing initiative focused on enabling data sharing, interoperability and reproducibility across the geosciences. In Australia, AuScope (2007-2018) provides access to MT instruments to allow researchers to image the subsurface of the Earth. Geoscience Australia, State and Territory Geological Surveys and research organizations collect MT data under government programs. All make MT data accessible as traditional file downloads from their sites and some use the National Computational Infrastructure for Virtual Laboratories and HPC processing of MT data.- Publication:
