By studying the tolerance of marine invertebrates to a wide range of temperature and pressure, scientists are beginning to understand how shallow-water species could have colonised the ocean depths.

Scientists believe that climate changes at various at various times during Earth’s history caused extinctions of creatures living at bathyal (1,000–4,…

Magmatic eruption

Recent research into the late stages of continental breakup, has shown that a final episode of plate stretching may be responsible for the eruption of large volumes of magma often seen at magmatic rifted margins.

This research was completed by Dr Derek Keir of the University of Southampton’s School of Ocean and Earth Science based at the National…
