MAC is focusing on the investigation of the lateral and spatial facies distribution, and its environmental control mechanisms in modern and ancient shallow as well as deep water carbonate systems.Our research combines data gathered during onshore and offshore expeditions. In order to improve the understanding of lateral facies distribution we are using a wide range of data, such as marine surface sediment samples, soft sediment and hardrock cores, outcrop analysis, bathymetry and subbuttom profile data, satellite images and high resolution drone based photogrammetry.
Outcome of our research will be used to develop novel facies templates for subsurface reservoir modelling. Furthermore, with the aim to establish the future diagenetic potential of the sediments their geochemical composition will be analyzed to derive information on the distribution of mineralogy and geochemical composition (trace elements and isotopic composition). Besides applied research we are also tackling fundamental research topics in the Red Sea, such as the paleoclimate and -oceanography, and controlling mechanisms on carbonate platform architecture.
April 2019 - Research Cruise: Al Wajh II - Slope Morphology and Sediment processes of southern Al Wajh Slope (RV Thuwal).
December 2019 With the last cruise completed on 10. Nov, MAC as part of CarResS Geology Group of Prof. Volker Vahrenkamp can look back to a successful year 2019 of offshore research activities in the northern Red Sea. Under the lead of Dr. Alexander Petrovic, the target of three research cruises between March and November 2019 was the Al Wajh carbonate platform. Al Wajh represents the largest land-attached carbonate platform in the Red Sea and is located north of the city Umluj. The two main objectives were to investigate the platform interior including the modern surface sediment distribution, and the downslope transport processes from the platform top towards surrounding small sediment basins. Dr. Alexander Petrovic and his team (Inda Putri, Nur Lyiana Yahaya, Rangelys J. Sorrentino and Manuel Ariza Fuentes) collected during the three cruises (in total 44 days on sea) more than 250 surface sediment samples and measured around 800 km sub-bottom profiling data in the platform interior. Moreover they mapped via a Kongsberg multibeam system an area of around 3,700 km² on the Al Wajh slope and collected more than 100 m gravity cores. CarResS Geology Group thanks Cmor, especially Francis L. Mallon, Brian C. Hession and Rodrigo P. J. Kumara for their technical support, Ramzi S. Aljahdali and Gazi Aljahdali. We also thank captain Yuri Brovka of RV Thwual and his crew, as well as captain Abdullah A. Aljahdali of RV Explorer and his crew. Special thanks goes to ship’s cook Aneez M. Usoof how took care of all crew members and scientists with his fabulous cooking skills and welfare during all three cruises.
