From petty predators to gentle giants: On the evolutionary history of the largest animals that have ever inhabited our earth

Whales developed the most colossal vertebrates with some of the most impressive adaptations evolution has ever produced. After the extinction of the dinosaurs, and with them all dominant marine reptiles, the oceans were conquered now by mammals during the Eocene and we look here today on a remarkable fossil record. The evolution of the large baleen whales is closely connected to the palaeogeographical developments of the southern hemisphere, the glaciation of the Antarctic continent and the corresponding constellation of water currents.

Oliver Hampe studied Chemistry and Geology-Palaeontology. The graduated geologist completed his doctorate in 1991 at the Johannes Gutenberg University of Mainz. Since 1996 he is working at the Museum für Naturkunde Berlin. 2003 he habilitated in Palaeobiology and Zoology at Humboldt University Berlin. His research focuses on extinct aquatic vertebrates, currently with emphasis on marine mammals.

3.Live discussion:
At 17:00 (German time) we will start the discussion, which will be moderated by Frank Riedel.

We changed the video-platform for the discussion, because the one we used so far has caused some problems:
We will now use BigBlueButton, an OpenSource solution, hosted at the FU Geosciences dept. by the section Planetary Sciences and Remote Sensing:
If you don’t know BigBlueButton yet, you may want to watch some introductory videos here:https://bigbluebutton.org/html5 

Only in case of emergency: In the event that we encounter serious problems, we will use WebEx meeting as a fallback option:https://fu-berlin.webex.com/fu-berlin/j.php?MTID=m71a072e732576b241dd4e85d6dd94c39 Meeting-no: 121 337 3244
Password: request by E-mail.

4.Discussion board: This is the link to the chatwall, which is also already open (without password):

Simona Pierdominici (PhD)
(GFZ Potsdam)

Present-day stress field analysis: case studies from scientific drilling projects

Knowledge of the in situ stress state of the Earth's crust plays a key role in understanding geological processes including plate tectonics, earthquakes, slope failure, and igneous emplacement. Here I present three case studies using breakout data from deep boreholes addressing the whole range of stress scales from global to local: local gravitational effects on Mauna Loa and Mauna Kea (Hawai´i), regional time-dependent deformation at Outokumpu (Finland) and global tectonics driven orientation of the present-day stress field in Italy.

Simona Pierdominici received her PhD in Geophysics from Bologna University and is since 2011 researcher at the GFZ. In 2015 Simona became member of the Operational Support Group of the ICDP. Her research focuses on the present-day stress field in the upper part of the Earth‘s crust and physical properties of rocks derived from borehole data and drill core.
