New ideas are all around us, but only a few will change the world. That’s our focus at JPL. We ask the biggest questions, then search the universe for answers—literally. We build upon ideas that have guided generations, then share our discoveries to inspire generations to come. Your mission—your opportunity—is to seek out the answers that bring us one step closer. If you’re driven to discover, create, and inspire something that lasts a lifetime and beyond, you’re ready for JPL.

Located in Pasadena, California, JPL has a campus-like environment situated on 177 acres in the foothills of the San Gabriel Mountains and offers a work environment unlike any other: we inspire passion, foster innovation, build collaboration, and reward excellence.

JPL is unique among NASA Centers in that its staff are Caltech employees, yet can access NASA technical resources. Cross-discipline teamwork is standard here: colleagues across JPL's science and engineering organizations and on Caltech's academic campus often work together. Learning to speak and understand other disciplines' languages is a doorway to the creativity needed to do what has not been done before. JPL staff are encouraged to create mission concepts that address humanity's core questions through a combination of science and technology. They are supported in developing ideas into proposals and hardware, and in communicating funded missions' results to the scientific community and the broader public. JPL seeks to employ scientists and engineers who are passionate about lifelong learning and excited to both contribute to and lead team efforts. We emphasize the importance of partnering across discipline boundaries and creating a friendly, constructive work environment to overcome space exploration's challenges. The Postdoctoral scholars at JPL benefit from an informal mentoring network, an annual conference showcasing their results, a dedicated seminar series, exposure to diverse career paths, and social connections across the JPL and Caltech community for advice on housing, childcare, and other aspects of living in southern California.

About the Project: 

The geomorphological structure and biogeochemical function of river deltas around the world are in constant evolution through natural processes, climatic, and anthropogenic events. In addition to being epicenters of economic activity, deltas play an outsized role in the global carbon cycle. Over the last decade, there have been significant advances in evaluating the carbon stocks and sequestration potential of coastal "blue carbon" ecosystems, but we lack a comprehensive understanding of the magnitude of lateral carbon export from these ecosystems to the ocean. Thus, our goal is to evaluate 1) the relative contribution of tidal rivers, swamps, and marshes to carbon export to the ocean and; 2) how do these fluxes vary over time. We specifically focus our efforts on the world's major deltas because of the unique ability for remote sensing to address the large challenge of mapping both complex vegetation distributions and dynamic interactions between river and tidal flows.  To achieve that, the candidate will use open source hydrodynamic models (e.g. ANUGA, SCHISM, TELEMAC, ROMS or ECODARWIN and ecogeomorphic models (marsh and mangrove productivity models), and calibrate and validate those models with SWOT, ICESat-2 and GEDI measurement of water surface elevation.   She/he will also use Land Cover and Land Use (LCLU) maps derived from a variety of remote sensing instruments.

Modeling carbon export using hydrodynamic models such as ANUGA or SCHISM, along with ocean circulation models like ROMS or ECODARWIN. 

Will also work with existing maps and seasonality data of coastal blue carbon ecosystems, river discharge, and optical data (Sentinel-2 and PACE) or existing carbon concentration products. 

Using SWOT and ICESat-2 data to calibrate and validate the hydrodynamic models in a large set of global estuaries and river deltas.

Required Qualifications:

PhD in marine science, physics, oceanography, environmental science or similar.

A good understanding of hydrology and/or surface processes in coastal watershed and also in the near-shore environment is necessary.

Knowledge or Programming in Python

Hydrodynamic modeling

Good publication record

Preferred Qualifications

Python
