He is focussed on supporting interdisciplinary projects related to marine biogeochemical cycling, ocean acidification, ocean deoxygenation, and climate dynamics. He earned his PhD from the University of British Columbia in 2019 and his MSc from the University of Toronto in 2013. His PhD thesis was focussed on reconstructing the history of oxygen in the ocean-atmosphere system and its links to the coevolution of life and climate. He worked on developing emerging and widely used geochemical tools that allow for more refined interpretations of Earth’s surface conditions captured in the rock record through time. Kohen conducted his post-doctoral research at the University of Hong Kong, where he worked on integrating geochemical data with conceptual computer models to understand the drivers, rates, and magnitude of ocean deoxygenation in Earth’s past and its connections to mass extinction events and climate change on different timescales. His current research interests are broad and include: ocean deoxygenation on varying timescales, the connections between climate and biogeochemical cycles, ocean chemistry and acidification, the role of microbes in marine biogeochemical cycles, the composition of marine sediments, and developing new and innovative biogeochemical proxy tools.

Martin Heesemann, PhD
Senior Staff Scientist

Dr. Martin Heesemann is one of ONC’s Senior Staff Scientists, focused on tectonics and seismology. He is responsible for the scientific integrity of ONC’s subsea seismometers and bottom pressure recorders, the data from which are used to study earthquakes and tsunamis, as well as tectonic processes related to seafloor spreading and subduction. As a marine geophysicist, he is passionate about collaborating with scientists and engineers in academia and industry to develop new and improved geophysical instruments that push the limits of what can presently be measured in the deep ocean.  Martin is involved in the development and deployment of CORK borehole observatories that enable long-term monitoring of the IODP (Integrated Ocean Drilling Program / International Ocean Discovery Program) borehole. Martin coordinates research activity related to several of these borehole observatories that are connected to ONC’s NEPTUNE observatory. Martin is also the scientific lead of the Northern Cascadia Subduction Zone Observatory (NCSZO) project whose goal is to monitor interseismic seafloor deformation that measures the buildup of energy that will be released during the next big Cascadia megathrust earthquake. Martin holds a Ph.D. in marine geophysics from the University of Bremen.

Steve Mihaly, PhD
Senior Staff Scientist

Steve Mihaly is a Senior Staff Scientists with a focus on interdisciplinary research enabled by ONC’s vast collection of visual and sound data captured by cabled observatories. His engineering background fosters his keen interest in the design of new instrumentation, our understanding of observations, and the design of observational programs. Steve has contributed to our understanding of how ocean dynamics are affected by rough ocean topography and hydrothermal venting. He has specifically studied these effects on hydrothermal fauna community behaviour and the dispersion of hydrothermal vent plumes.  Scientifically, he provides advice on the dynamics of the ocean, such as tidal currents, internal and surface waves, eastern boundary currents, and estuarine circulation, and the linkages of those physical mechanisms to the biological, biogeochemical, and chemical variability of the ocean. As a physical oceanographer, he works with other oceanographers to understand the bio-geo-physical linkages involved in coastal environments. Steve studied mechanical engineering (vibrations/acoustics) at Dalhousie University and holds a Ph.D from UBC in the complex dynamics of ocean currents at hydrothermal venting spreading centers.
