WELCOME!

We are a group of “climate-minded” oceanographers who investigate how the ocean works and how the ocean is affected by and responds to the ever-changing climate. More specifically, we are interested in 1) physical changes and variability in the global ocean; 2) exchange of the upper and deep layers of the global ocean; 3) roles of mesoscale eddies in connecting different parts and layers of the global ocean. If you are interested in our research or have any questions, please reach us at xfliang at udel.edu.

Congratulations to Minghai for publishing his second paper this year in GRL. This paper is entitled “ENSO Modulates Mean Currents and Mesoscale Eddies in the Caribbean Sea” and can be accessed here: https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2023GL103958 

Congratulations to Dr. Chao Liu for starting his Postdoc Position at WHOI!

Another paper led by Yingli Zhu, Near-inertial oscillations in the deep Gulf of Mexico, was published in Deep-Sea Research Part II. In this paper, we collected and analyzed a large set of mooring measurements in the deep part of the GoM to describe and understand the NIO. Among many other findings, we found intense bottom-layer NIOs in the northern GoM and they are related to the low-frequency currents, likely through flow-topography interaction. The full paper can be found here https://authors.elsevier.com/c/1hS1X3Ruf1NaiV until Sep. 8, and a preprint can be found here https://www.researchgate.net/publication/372142878_Near-inertial_oscillations_in_the_deep_Gulf_of_Mexico

One paper led by graduate student Minghai Huang was published in the Journal of Physical Oceanography.  In this paper, we described the seasonal variability of eddies in the Northwestern Tropical Atlantic Ocean and explored the underlying mechanisms using a novel analysis method.

One paper led by Yingli Zhu was published in Frontiers in Marine Science. In this paper, we describe the spatial and temporal characteristics of the Eulerian mesoscale eddies in the Gulf of Mexico based on multi-decade satellite data. The paper can be found here: https://www.frontiersin.org/articles/10.3389/fmars.2022.1087060/full

I gave a department seminar talk at UD to review the activities of our group over the past few years. A recording of the talk can be found here https://capture.udel.edu/media/SMSP+Spring+2022+Colloquia+Speaker+Series+-+Dr.+Xinfeng+Liang/1_6g3ml806/187881983

April

Our paper on the western boundary current upwelling was selected as a Research Spotlight by AGU EOS https://eos.org/research-spotlights/hidden-upwelling-systems-may-be-overlooked-branches-of-ocean-circulation

March

After a long and bumpy journey, our paper on the upwelling associated with the major Western Boundary Currents was finally accepted in JGR-Oceans. We believe this upwelling is an overlooked branch of the global ocean circulation.
