Hydro-Geodesy Synthesis Workshop Application Deadline

Aug 04, 2017

Geodetic techniques are becoming increasingly important for observing the hydrological cycle. The GRACE satellite mission has been monitoring changes in terrestrial water storage (TWS) over the entire Earth for the past 15 years, and GPS measurements of surface deformation are helping to increase the resolution of these TWS change estimates.  Additionally, GPS reflectometry is in operational use for monitoring soil moisture and snow depth at continuous GPS stations in the western USA and Canada. Reflectometry can also yield measurements of lake and reservoir height changes, and NASA’s upcoming SWOT mission will monitor surface water levels over the entire planet. Finally, interferometric synthetic aperture radar (InSAR) is in widespread use for monitoring anthropogenic groundwater extraction and recharge, as well as surface water level changes in wetlands.

In light of these developments, NSF’s EarthScope program is sponsoring a workshop to forge collaborations between geoscientists and hydrologists interested in crossing disciplinary boundaries to gain new insights into their domains.  Thematic topics will include new observations of hydrological budgets, scales and fluxes; teleconnections between terrestrial and oceanic phenomena; deformation and stresses from hydrological loading and groundwater extraction/recharge; and removing hydrological signals from geodetic time series. Workshop attendees will assess the scientific and operational potential of new techniques, provide guidance for future methodological developments, and plan for the dissemination and use of new observations as they become available.  

The workshop will be held at the Scripps Institution of Oceanography in La Jolla, CA on October 25-27, 2017. Please visit http://www.earthscope.org/research/synthesis_workshops/Hydro_geodesy to apply; deadline is by 11:59 PM AKDT Friday, AUGUST 4, 2017.
