MITberg

This month we report work by Alan Condron (UMass) using MITgcm, coupled with geological data, to show that massive icebergs and large volumes of meltwater were periodically transported along the east coast of North America as far south as southern Florida during the last deglaciation

MIT postdoc Roberta Sciascia has been using MITgcm to explore the variations in submarine melt rate of Helheim Glacier induced by glacier and intermediary circulations.

Cool off with a study from Ashkenazy, Gildor, Losch and Tziperman who use MITgcm to explore the ocean in models of snowball earth.

In new work published in Nature Communications in July, an international team of scientists from the Massachusetts Institute of Technology and the Institute of Marine Sciences of Barcelona, Spain in collaboration with the National Centre for Scientific Research, France have been using MITgcm to study the balance between phytoplankton diversity and productivity.

This month we focus on Alan Condron, a Research Assistant Professor in the Climate System Research Center at the University of Massachusetts Amherst, who uses MITgcm to investigate past and future climate sensitivity to changes in Arctic meltwater.

This month we spotlight work by Ryan Abernathey who has been using MITgcm to map surface mixing rates globally.

In a novel approach, MITgcmers Ian Fenty and Patrick Heimbach use optimal state and parameter estimation to improve the sea-ice simulations.

Nuno Serra from the University of Hamburg has used MITgcm in many ocean modeling projects, both from a process-modelling perspective and “realistically”, incorporating forcing from NCEP and ECMWF. He is especially interested in the processes regulating North Atlantic and North Pacific inter-annual to inter-decadal variability. A particular passion is overflows.

In a recent paper in the Journal of Physical Oceanography, An Nguyen (MIT) and co-authors Ronald Kwok (JPL) and Dimitris Menemenlis (JPL) report on work using MITgcm to better understand the origin and character of  the western arctic, upper halocline.

At this time of the year newspapers and magazines abound with suggestions for things to read on vacation. MITgcm recommends popping copies of the following recent papers in your beach bag, after all, there’s more than one way to study the ocean!
