Eustasy and sequence stratigraphy in the Cretaceous Greenhouse

Dear Colleagues,

We would like to invite you to take part in the Science Meeting that will be held in Bucharest, between the 23rd and 25th of August 2014, and will be followed by two field-trips, in the interval 26-28th of August – Eastern Carpathians) – FIELD 1 and 29th-31st of August (Southern Carpathians). – FIELD 2, organized in the frame of IGCP 609: Climate-environmental deteriorations during greenhouse phases: Causes and consequences of short-term Cretaceous sea-level change.

The main themes tackled are:

  • Regional versus global mechanisms for sea-level change

    By bringing together specialists from both the palaeoclimatology and palaeoceanography scientific community as well as the geophysical scientific community the main mechanisms for global and regional sea-level changes will be evaluated and can be quantified.

  • The stratigraphic response

    By combining these groups with experts for Cretaceous stratigraphy the meeting aims to correlate sea-level records from globally distributed sedimentary archives to the new, high-resolution absolute time scale, using, e.g., sea-water isotope curves, magnetic signals and orbital (405, 100 kyr eccentricity) cycles. This will resolve the question whether the observed short-term sea-level changes are regional (tectonic) or global (eustatic) and determine their possible relation to climate cycles. This will result in a refinement of existing cycle charts and sequence stratigraphy frameworks.

  • Rates of past sea-level change

    Based on these be the calculation of rates of sea-level change during the Cretaceous greenhouse episode. Rates of geologically short-term sea-level change on a warm Earth will help to better evaluate recent global change and to assess the role of feedback mechanisms, i.e. thermal expansion/contraction of seawater, subsidence due to loading by water, sediment influx and changing vegetation of the Earth System.

We are looking forward to see you in Bucharest!
