Over the past decade, Dr. John Hildebrand and Ana Širović from Scripps Institute of Oceanography (SIO) have developed the capability to study marine mammal populations using passive acoustic monitoring. The High-frequency Acoustic Recording Package (HARP) has exceptional bandwidth and recording capacity to allow study of the full range of marine mammal species over extended deployment periods. During the DWH oil spill, five HARPS were deployed in the GOM and documented the presence of marine mammal near the DWH wellhead.
Dr.'s Michael Schlüter, Andreas Liese, Dieter Krause, and Rudolf Müller are a part of the research center “Energy and Environment” in the Institute of Product Development and Mechanical Engineering Design and the Institute of Multiphase Flows at the Hamburg University of Technology (TUHH). This research team is at the cutting edge of experimental apparatus development for investigation of oil plume seawater interaction in the deep-sea environment (Task 2).
The pressure laboratory DL2 can reproduce the major environmental parameters of the deep-sea, forming either a segment of the sediment–water interface or of the water column inside an experimental volume of 100L. Natural samples (fluids, suspensions, biota, sediment cores) can be transferred from transfer units into the pressurized lab space. The system is mobile to operate on- and offshore. A suite of interfaces enables the scientists to monitor, manipulate, control and sample the objects of investigation and the environment inside the laboratory in real time by incorporation of latest laser technology for quantification of arising hydrodynamic and chemical processes. Scope of the studies at TUHH also includes the aspects of biodegradation under pressure.
Dr. Scott Socolofsky is an expert in modeling the near-field plume of an accidental subsea oil release. Experiments will be conducted in the PI's laboratory to validate designed models in near-field oil distribution. Near-field dispersion refers to a mixture of oil and gas hydrates soon after exiting the well. As the near-field plume ascends in the water column, gasses dissolve and oil droplets remain (Far-field modeling).
Dr. Wes Tunnell is a marine ecologist and an expert in implications of coastal oil spills on coastal ecosystems.
