The mystery of Mayotte
In May 2018, something very curious happened. The marine area immediately to the east of Mayotte, the easternmost major island in the Comoros chain, became seismically active.
The Aves Ridge and the migration of mammals
The leading article in the November 19 issue of Eos was entitled “By Land or Sea: How Did Mammals Get to the Caribbean Islands?” Could gravity maps have anything to tell us about the possibilities?
A geophysical rant
In an ideal world, there would be a continuous dialogue between geologists and geophysicists. Sadly, there seems to have been little progress in that direction in the last fifty years.
A confusion of units
Gravity units are a mess. About half of all surveys have their results reported in the c,g,s unit, the mGal, and half in the S.I unit, which differs by a factor of ten. And very few people have any idea of why the Eötvös unit is defined in the way that it is.
Mohorovičić geophysicist
There is no doubt that Andrija Mohorovičić deserves to be remembered. The work he did laid the foundations for the use of earthquake waves in understanding the Earth, but brilliance has not always been enough to ensure that a scientist is remembered. His work might easily have been overlooked, or lesser men might have received the credit, but this is one case where the right man has been honoured.
The young Mohorovičić
For scientists their late twenties and early thirties are commonly crucial years. They may not do their most important work during them, but it is then that they establish the habits and attitudes that will serve them throughout their careers. Andrija Mohorovičić may not have established a lasting reputation in Bakar, and the work he did there may be largely forgotten, but without Bakar he might never have had a reputation of any sort.
