Scientists have discovered an anomaly related to the increase in the level of beryllium-10 in ocean sediments at the bottom ...
Sedimentation is controlled by them, and the stratigraphic series constitutes a record, written on tablets of stone, of these lesser and greater waves which have pulsed through geologic time.” ...
Telluride is a Cubist’s rendering of mountains. Overlapping triangles rim the horizon; the valley floor meets the box canyon walls at neat right angles; a few oval abstractions soften the ...
Understanding Earth's Deep Past provides an assessment of both the demonstrated and underdeveloped potential of the deep-time geologic record to inform us about the dynamics of the global climate ...
The beginning and end of each chunk of time in the geologic time scale is determined by when some species appeared or disappeared from the fossil record. When many species went extinct around the same ...
Sometime this century they may become acidified to the point that corals can no longer construct reefs, which would register in the geologic record as a “reef gap.” Reef gaps have marked each ...
In the field of paleoclimatology, our overarching objective is to use the geologic record to understand how Earth’s climate system operates. Paleoceanography may focus on the role of the oceans in ...
For example, analyzing the geologic history can uncover a more detailed record of past earthquakes preserved in the rocks. This knowledge allows scientists to make more informed assessments about ...
