Identifying tsunami deposits using bivalve shell taphonomy
S.V. Donato et al., McMaster University, School of Geography and Earth Science, Hamilton, Ontario L8P 4A9, Canada. Pages 199-202.
On 28 November 1945, off the coast of what is now Pakistan, a large earthquake (8.1 Mw) produced a destructive tsunami. Despite news reports chronicling the tsunami in Pakistan, Iran, and India, no records describing the magnitude of the event exist for Oman. Donato et al.s study documents the characteristics of a shell bed deposited by the 1945 tsunami in Sur Lagoon, Oman, and describes a new technique for identifying tsunami deposits in the geologic record using shell preservation. This shell bed provides the first physical evidence that the large tsunami impacted this region of Oman.
Rapid warming and salinity changes of Cretaceous surface waters in the subtropical North Atlantic

Paleo records reveal occasional and rapid releases of greenhouse gases into the atmosphere. The regional consequences on the surface ocean processes and timing between the atmospheric changes and ocean changes, however, are still far from understood. Wagner et al. examined an exceptionally well-preserved section of the
