We are part of the “Ecosystem Impacts of Oil and Gas Inputs to the Gulf - ECOGIG" Consortium, lead by Un. Miss. Our goal is to improve understanding of how future
spills may affect sensitive areas, learning how oil behaves at different
depths and comparing data from the BP blowout with that from natural
oil seeps in the Gulf of Mexico. Link to the ECOGIG web page
Collaborative Research, Type 1: Climate Sensitivity, Stochastic Models and GCM-EaSM Optimization
collaborative project with Profs. M. Ghil, J. McWIlliams and D. Neelin
at UCLA, Prof. S. Wang at Indiana Un. and Prof. I. Zaliapin at Un. of
We seek to understand the sensitivity and predictability
potential of low frequency variability modes in the climate system when
subjected to climate change and the sensitiviy of the climate models
when trying to represent them using a hierarchy of models, from
conceptual "toy" models through intermediate climate models and on to
Earth system Models of Intermediate Complexity . Funded by NSF-DMS

Validation and quantification of uncertainty in coupled climate models using network analysis. With Prof. C. Dovrolis (GaTech, College of Computing).
goal of this project is to develop a fast, scalable and cutting-edge
computational toolbox to infer and analyze climate networks. We are
analyzing the network structure, and therefore the teleconnections,
of observational/reanalysis data-sets and various state-of-the-art
(CMIP5) climate model outputs. Our goal is to quantify uncertainties in
climate models, and clustering models or integrations with
qualitatively different topological characteristics as
climate scenarios. Additionally, we will characterize how/whether
networks changed over the recent past and how it may change under global warming scenarios. Funded by DOE.

Collaborative Research: Nitrogen fixation, nutrient supply and biological production in the Gulf of Mexico. With Prof. J. Montoya (GaTech, School of Biology) and Prof. T. Villareal (U. Texas - Austin).
a high resolution regional ocean model we investigate the interplay of
physical, chemical, and biological factors in supplying nitrogen, an
essential nutrient, to coastal and offshore waters of the Gulf of
Mexico. The Gulf of Mexico is strongly influenced by both riverine
inputs and advective processes, providing an excellent model system for
studying nutrient dynamics, physical forcings of productivity at the
meso- and submeso-scales, terrestrial-oceanic linkages, and the
potential impact of land use and climate change on marine ecosystems.

Vortex dynamics and interannual variability in the Labrador Sea.
a regional ocean model with 7.5km horizontal resolution we are
investigating the role of eddies in restratifying the Labrador Sea and
their impact on the vertical mixing. We are also exploring the eddy
kinetic energy variability in the basin and the evolution of
potential temperature through the water column in the last 30 years.
