Exploring ENSO-Related Global Ocean Heat Content Variations in ECCOv4

Researchers from China and Australia have been using the ECCOv4 dataset, an MITgcm product, to investigate ENSO-Related Global Ocean Heat Content Variations.


What you Can Do With a Really Rather Realistic Ocean Model


This month we spotlight research from MIT’s Darwin Project exploring how changes in spatial resolution impact emergent biogeochemistry and phytoplankton community structure in their work using MITgcm and the biogeochemical models they have built to surround it.


The Cost of Chalk

This month we spotlight recently published work by Fanny Monteiro, Stephanie Dutkiewicz, and others, who have been using MITgcm to explore the biogeography of a class of phytoplankton with an outsized role to play in the global carbon cycle.


2016 ECCO Joint Project Meeting

This month we spotlight the ECCO meeting held May 16-18, 2016 at MIT.


Sea – Ice Interplay

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


Overflowing with Movies

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.


MITgcm on Ice

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.



OCCA

Surface height anomaly from OCCAThis month we focus on work by Gael Forget and the ECCO team who have been using MITgcm to construct a new ocean atlas. By using MITgcm as a means of optimally synthesising data within the framework of a physically accurate general circulation model, OCCA (short for OCean Comprehensible Atlas) provides a singularly accurate 3-year “snap-shot” of the global ocean state for the period December 2003 to November 2006…


Anthropogenic CO2 transport in the Southern Ocean.

In and out: Driven by winds, the Southern Ocean's currents (blue globe) transport CO2 (red) northward. Credit: T. Ito et al., Nature 463 (2010)Taka Ito, Molly Woloszyn and Matt Mazloff have been studying anthropogenic CO2 transport in the Southern Ocean. Using MITgcm’s adjoint and offline capabilities, the team find a clear correlation between the pattern of carbon uptake and oceanic vertical exchange in strong support of wind-driven primary regulation of Southern Ocean ACO2 transport…
