Carenza Williams is joining the group as a PhD student in physical oceanography and ocean modeling. Carenza holds a Masters degree in Earth Sciences from the University of Oxford. Her Masters thesis was on the influence of future climate change on ocean overturning pathways and circulation timescales. Welcome to JHU Carenza!

Tipping points in overturning circulation
Members of the Haine group have contributed to a new manuscript on the global ocean overturning circulation. The paper is led by Prof. Anand Gnanadesikan and is titled “Tipping points in overturning circulation mediated by ocean mixing and the configuration and magnitude of the hydrological cycle: A simple model.” Anand has submitted the paper to […]
Inaugural Dr. George S. Benton Postdoctoral Fellow in Oceanographic & Atmospheric Sciences
Dr. Prajvala Kurtakoti joins us this summer. Prajvala is the first Benton Fellow, supported by a generous gift from the family of Dr. George S. Benton. George Benton was a professor of meteorology at JHU for more than 40 years. He was also department chair, Dean of the School of Arts & Sciences, and Vice […]
Pedagogical tool and documentation for ocean fluxes
Monitoring ocean fluxes of mass, heat, and freshwater is an essential part of physical oceanography. For example, we see decadal fluctuations in the strength of the currents in the northern North Atlantic Ocean. These changes cause more or less heat and salt to gather in the Iceland Sea, west of the UK and Ireland. But […]
New NSF project on impacts freshwater on the subpolar North Atlantic Ocean
Tom has been awarded a new NSF grant entitled “Impacts of Arctic freshwater export on the subpolar North Atlantic Ocean circulation“. This study seeks to understand how the melting of Arctic ice and extra Arctic precipitation can influence the ocean currents in the North Atlantic. The study also asks how much of the Arctic meltwater […]

Talk on Conceptual Models of Polar Overturning Circulations
Happy New Year! Tom welcomed 2023 with a talk as part of the Water mass changes and transformations in the Arctic Ocean: Physical Oceanography Community of Practice webinar. See the video here.
Arctic freshwater impact on the AMOC: status and prospects
Tom gave a talk at the Atlantic overturning: new observations and challenges discussion meeting of the Royal Society, London. You can watch the talk here.
Using Hydraulic Theory to Monitor Dense Overflows in a Parabolic Channel
Dr. Atousa Saberi, a former graduate student in our group, has published a paper in the Journal of Physical Oceanography. The work is based on her PhD thesis and concerns monitoring of deep overflows, for example through the Faroe Bank Channel. The abstract reads: Deep ocean passages are advantageous sites for long term monitoring of […]
How do the Arctic and AMOC interact?
Team members Ali Siddiqui and Tom Haine have co-authored a paper entitled “Interactions between the Arctic Mediterranean and the Atlantic Meridional Overturning Circulation: A Review.” The paper appears in a special issue of Oceanography on The New Arctic Ocean.
