New research suggests that the North Atlantic subtropical gyre may have been much stronger and deeper during the Last Glacial Maximum, despite the prevailing cold climate and presence of ice sheets. Tom Marchitto was part of a research team led by Jack Wharton of University College London.

A team of North Carolina State researcher and INSTAAR Tom Marchitto have developed a robot capable of sorting, manipulating, and identifying foraminifera—microscopic marine fossils that play a key role in our understanding of the world’s oceans and climate past and present. An open-source paper describing the work has been published in the AGU journal Geochemistry, Geophysics, Geosystems; and the robot itself will be made open source.
