GHRSST XXI has moved on-line: see the meeting web page for details: https://www.ghrsst.org/meetings/21st-ghrsst-international-science-team-meeting-g-xxi/.
We realise that many who may not have been able to attend the meeting in Boulder would now like to participate in the on-line meeting so we have extended the deadline for submission of abstracts for poster presentations only to 27th March 2020.
