Crossing the line

This cruise has been a bit unusual in that we transited the equator four times, and, given our proximity to the vernal equinox, we jumped between all four seasons. As exciting as this is from both a geographical and celestial point of view, I hadn’t appreciated the naval significance of ‘crossing the line’. I soon […]

The Institut de Physique du Globe in Paris (IPGP) runs geophysical observatories that monitor earthquake […]

The group at Bristol has deployed seismometers in some of the harshest conditions on Earth, including the Canadian Arctic and the Afar region of Ethiopia and Eritrea. Operating a seismometer at the bottom of the ocean presents a whole new set of […]
