PESA ACT/NSW September Technical Lunch

PESA NSW September Technical Meeting

Exploring the deep sea floor

John will talk about his work with Bruce Heezen and Maurice Ewing at Lamont Geological Observatory of Columbia University NY.

The talk will discuss discoveries using deep sea cores in the Atlantic Ocean made in the 60s and 70s. Examples will include;

• Turbidite deposits from the Grand Banks off Canada.
• Also in the Puerto Rico Trench where individual sands were correlated using the colors of the upper muddy parts of the flows.
• Other work will show the movement of melting ice sheets using raft detritus found in the cores.
• Slides and a unique video of Bruce Heezen will be used in this talk.
