November Ramble: “125,000 years of Khor Al Adaid (Inland Sea) through the looking glass of geology and ecology”

The 3rd QNHG ramble of the season is on Friday, November 3rd, 2017 - 


The trip will include several stops:

  1. A dune overlook of the inland sea to orient the trip discuss the large-scale natural processes that form this stark landscape.  
  2. A stop at the Inland Sea shoreline to discover the secrets of microbial marine mats.  
  3. A lunch stop near the Inland Sea Delta. Wading is encouraged.
  4. A visit to sand mounds that host a 6000 year old mollusk deposit.
  5. A stop at a 125,000 year old outcrop of Pleistocene rock to get sense for the environments here at that time.
  6. A stop and short walk to a “salt flat” where gypsum and halite crystals can be found at surface. This stop is optional, and also dependent on recent weather (if it rains prior to our arrival- the salt will not be there). 

Gathering time and place:

Sealine- just past last round about at 8am. Duration approximately 7 hours

Trip Leaders Bio

  1. Dr John Rivers is a geologist working for ExxonMobil Research Qatar with nine years’ of research experience in petroleum-related geologic systems. His current research focuses on characterization of limestone sediments and rocks forming in modern Qatar coastal environments, and occurring in the local subsurface rock record.

  2. Ms. Ruqaiya Yousif works as an environmental Specialist for Qatar Center of Coastal Research (QCCR) and environmental team in ExxonMobil Research Qatar. Her work involves remote sensing and mapping, hydrodynamic and sediment transport modeling, and core description and geochemistry (paleo-environment).
  3. Dr. Aspa D. Chatziefthimiou is an ecologist and her work centers in extreme environments. Currently she is a Visiting Research Scientist at Weill Cornell Medicine and Exxon Mobil Research. She is very active in the field of sustainability and urban ecology as a Scientific Advisor at QGBC and a Principal Investigator for MetaSUB. Dr. Chatziefthimiou is a passionate educator and through the ecological consultancy Richer Environments, she organizes a myriad of outreach activities and eco-tours to expose the general public to the beauty of nature.
