Study using new method of dating corals reveals that sea level is more variable over shorter periods of time than previously thought

Sea level may be far more variable over shorter periods of time than can be explained by natural variations in the Earth’s orbit. Scientists using a new method of dating fossil coral reefs have uncovered evidence that sea level is capable of changing by as much as 30 meters in just a few thousand years–more quickly and more dramatically than

Deep ocean research stretching from the Arctic to the Black Sea is to receive 15 million euros (around £10 million sterling) as part of a programme involving 15 countries across Europe.

Led by Southampton Oceanography Centre’s Professor Phil Weaver, the HERMES project (Hotspot Ecosystem Research on the Margins of European Seas) will study ecosystems along Europe’s deep-ocean margin and is one of the largest research projects of its kind.

Researchers at the British Antarctic Survey (BAS) and the University of California, Santa Cruz have discovered that Earth’s last great global warming period, 3 million years ago, may have been caused by levels of CO2 in the atmosphere similar to today’s.

Reporting this week in a leading Earth Science journal, Geochemistry Geophysics Geosystems, the scientists describe how they tested two widely held ideas that attempted to explain the balmy conditions on Earth at that time. Their f

Scientists have long held the belief that the fracturing of the Earth’s brittle outer shell into faults along the deep ocean’s mountainous landscape occurs only during long periods when no magma has intruded. Challenging this predominant theory, findings from a completed study show how differences in mid-ocean ridge magma-induced activity produce distinctly different types of ocean floor faulting. W.

A new method for dating destructive past earthquakes, based on evidence remaining in caves has been developed by scientists at the Hebrew University of Jerusalem and the Geological Survey of Israel.

Using this method, they discovered for the first time evidence of earthquakes that can be documented some distance from the Syrian-African rift that runs from Syria through Lebanon, Israel and Jordan and down into Africa. This rift caused great shifts in the topography of the region
