The ocean floor closely observed: will it subvert marine geology?

Marine Geology

To constrain the timing of rifting in the western, eastern, and northern parts of the Alboran Sea basin, seismic reflectors, corresponding to biostratigraphic boundaries and unconformities from the Miocene to Recent, are correlated using synthetic seismograms. Regions of adjacent coeval compression and extension are found in the Alboran Sea basin. Normal faulting continues in parts of the easte...

Closely observed pains.

Outside the groves of academe few people today read George Crabbe's trenchant rhymed couplets describing the life and landscape of his native Suffolk in the late eighteenth and early nineteenth centuries. This is a pity because Crabbe is a real original: an unpoetical poet who believed that it was his duty to instruct his readers as accurately as possible about the painful realities ofhuman lif...

Fissure Basalts and Ocean-Floor

closed system grossly distorted sound calibration below 1 khz, whereas at frequencies higher than 6 khz calibration for the open loudspeaker was affected. This difficulty could be avoided by placing the loudspeaker close to the bird's ear (12 cm). 2. R. L. Boord and G. L. Rasmussen, J. Comp. Neurol. 120, 463 (1963). 3. For this reason, all data on single-unit thresholds and frequency range in t...

South Pole-aitken Basin: Geology, Basin Floor, and Unit Compositions

At 2600 km diameter, the South Pole-Aitken (SPA) basin is the largest on the Moon and has profoundly influenced lunar crustal configuration and subsequent evolution [1-4]. SPA is significant for two principal reasons: 1) its immense size suggests that it has excavated most or all of the lunar crust at its target site, thus giving us a window into the very deep lunar interior; 2) because it is t...
