Gateways 2020 is scheduled from October 12 to October 23, with the tutorial and workshop track during the first week and the main conference track during the second week. This fifth Gateways annual conference is an opportunity for gateway creators and enthusiasts to learn, share, connect, and shape the future of gateways, while supporting and growing our community. Register for the conference by October 5.

The default time zone is Eastern Time. You can adjust it to your time zone on the right side of the schedule underneath the search box (or in the top bar, depending on the width of your screen).

A3: IsoMAP - A Science Gateway for Isotopic Landscape Modeling

Stable isotopic landscape (aka isoscape [1]) modeling brings new insights into the study of a wide array of research questions in multiple disciplines. However, the adoption of isoscape modeling has been hindered by the obstacles individual researchers face in collecting, compiling, and integrating heterogeneous environmental and isotopic data over large spatial and temporal scales and in developing and interpreting geostatistical models. To help address these challenges, we developed IsoMAP (http://isomap.org/), a science gateway for online isoscape modeling, analysis and prediction. IsoMAP accesses and integrates a number of diverse datasets and enable users to develop isoscape models over selected spatial and temporal domains using geostatistical algorithms, predict maps for the stable isotopic ratios of water and plants, and associate a sample’s isotope value with its most likely geographic origin. Up until now, there are more than 2400 registered users who have run around 14,000 simulations in the IsoMAP gateway. In this demo, we will demonstrate how researchers can use the IsoMAP gateway to develop isoscape models, run the developed models to generate map predictions for H and O isotopes in precipitation water and plant water, and map a sample’s origin.
