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.

Collaborative Research, Type 1: Climate Sensitivity, Stochastic Models and GCM-EaSM Optimization
A 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 Nevada.
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 .

Validation and quantification of uncertainty in coupled climate models using network analysis. With Prof. C. Dovrolis (GaTech, College of Computing).
The 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
distinct 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).
With 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.

Proposal Summary

Paper on Sargassum distribution and submesoscale turbulence in the Gulf of Mexico (published in L&O :F&E)

Vortex dynamics and interannual variability in the Labrador Sea.
Using 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. Funded by NSF-OCE-PO.
