The new measurements in this research were made with cores that showed the results
of massive
amounts of sediments released by subsea landslides during a
subduction zone earthquake — a catastrophic event beneath the sea as well as on land.
who believe there is a
subduction (and http://hockeyschtick.blogspot.fr/2013/09/new-paper-finds-oceans-are-net-source.html) «At temperate latitudes, the
subduction of DIC and to a much lesser extent... At the global scale, these two large counter-balancing fluxes
of DIC
amount to +275.5 PgC yr — 1 for the supply by obduction and — 264.5 PgC yr — 1 for the removal by
subduction which is 3 to 5 times larger than previous estimates.»
