The overarching objective of the Solid Earth Response and influence on Cryospheric Evolution (SERCE) scientific research programme is to:
Advance understanding of the interactions between the solid earth and the cryosphere to better constrain ice mass balance, ice dynamics and sea level change in a warming world.
This objective will be accomplished through integrated analysis and incorporation of geological, geodetic and geophysical measurements into models of glacial isostatic adjustment (GIA) and ice sheet dynamics. The programme is designed to synthesize and integrate the extensive new geological and geophysical data sets obtained during and subsequent to the International Polar Year with modeling studies, in a timeframe to contribute to IPCC AR6.
More information about the SERCE goals and objectives can be found in the implementation plan.
Statement on Antarctic geodetic infrastructure: SERCE urges national agencies to expand and maintain existing geodetic infrastructure across Antarctica. The long-term deployment of geodetic infrastructure across Antarctica is required to measure three-dimensional Earth deformation and gravity fields. Datasets with high spatial resolution from sites operating continuously is especially critical in regions of low mantle viscosity and ongoing ice loading changes (e.g. West Antarctica and Antarctic Peninsula).
Statement on Antarctic seismic infrastructure: SERCE urges national agencies to support the spatially extensive and regionally targeted deployment of broadband seismometers across Antarctica. Spatially wide-spread observations are required to determine mantle and crustal properties, including rheology and geothermal heatflux.
Statement on data provision: SERCE strongly encourages the open and freely available provision of datasets relevant to its aims, notably seismic data relevant to sensing the interior properties of the solid Earth and geodetic data allowing measurements of solid Earth deformation or gravity field change. Where such datasets are not provided immediately upon collection we urge data collection agencies to provide metadata in an open repository. Example data and metadata repositories include the SCAR GNSS database (https://data1.geo.tu-dresden.de/scar/index.shtml), UNAVCO (www.unavco.org) and IRIS PASSCAL (http://www.passcal.nmt.edu)
