Cara James is a new Geophysics PhD student within the EOAS department at UBC, investigating the fluid dynamics of particle clouds produced during deep-sea mining and modelling how they may impact ocean health. Cara moved to Vancouver in January 2022, having completed her undergraduate degree in Natural Sciences and masters in Earth Sciences in the UK.

The Department is pleased to announce that Dr. Stephanie Waterman has won the Charles A. McDowell Award. This award, consisting of a medal and a certificate, is presented to an outstanding young faculty member who has demonstrated excellence in pure or applied scientific research.

Stephanie is a sea-going physical oceanographer interested in the fundamental role that ocean mixing processes play in climate dynamics, and how these mechanisms control the distribution of heat, energy, chemicals and marine organisms globally. 

She approaches her research both through observational and theoretical perspectives, using targeted field observations, observational data analysis, idealized process modeling, analytical analysis and lab studies. Her main aim is to observe real-world systems, identify the important physical processes generating individual phenomena, and reduce their complexity to a useable and useful model.

Congratulations to Dr. Waterman!

The Department is pleased to announce that Professor Catherine Johnson has been awarded the Killam Research Prize, an award which recognizes the outstanding research contributions of faculty from across all disciplines. Prize recipients are celebrated for creating and disseminating knowledge that has a global impact.

Dr. Johnson’s work is more than global, and focuses on the history and evolution of terrestrial planets – namely, Mercury, Mars and Venus. She uses remotely-sensed geophysical data to better understand the history and evolution of terrestrial planets, and has worked on several NASA planetary missions, including the Mars InSight mission and the Mercury MESSENGER mission. Her current work aims to understand the magnetic fields of Mercury and Mars, including when and why they formed, their current state, and how the fields interact with the solar wind. “A huge unknown” she explains, “is the level to which magnetic fields protect a planet’s atmosphere from space weather”, a question with implications for human space exploration and habitability in this solar system and beyond.

Her work also focuses on planetary evolution and internal structure, and what that means for current planetary seismic and volcanic activity. Dr. Johnson works with a wide range of remotely sensed data, including altimetry, radar and gravity measurements. Data is collected by lightweight, low-power, instruments specifically designed to resist the challenges of operating in space.

“You’re required to be very creative, in a responsible way” she says of the intrinsic limitations on data quality and availability. Leaps and bounds in instrument technology between missions means that new data can improve on in resolution by an order of magnitude or more, revealing in detail features that may have previously taken up only a handful of pixels. “I love it; with each new mission to a planet or moon or asteroid you almost always see something unexpected.”

Looking forward, Professor Johnson is excited for multiple upcoming missions to Venus which will collect data on the composition and structure of the planet’s atmosphere and surface. She plans to answer questions about Venus’ suspected volcanic and tectonic activity using data previously shrouded from view by the planet’s thick, toxic atmosphere. “Venus was my first planet” she says, referring to the geophysical work she did on the planet during her PhD and postdoctoral studies. “It is so different from the Earth in so many ways, but would look equally habitable to our planet from a galaxy away – why is that?”

Though not directly involved in the upcoming missions, Dr. Johnson will have access to the resulting publicly available data. With datasets so sparse and expensive to obtain, collaboration is a driving force in propelling the field of planetary science forward. She stresses the key role it has played in her research group’s success: “this award is an honour, and it’s not about me; its about the people who I’ve had the privilege to work and collaborate with.”

Dr. Shandin Pete, Assistant Professor of Teaching in the Department of Earth, Ocean, and Atmospheric Sciences at the University of British Columbia, is investigating connections between natural phenomena and Indigenous scientific knowledge. 

Check out the recent episode of the CBC radio show The Early Edition where Dr. Pete talked about Indigenous hydrology and astronomy. 

To learn more about what scientific clues Dr. Pete found Indigenous stories reveal, check out the article by UBC News: Indigenous stories reveal the science of the world around us.

Dr. Pete is a hydrogeologist and science educator with interest in Indigenous research methodologies, geoscientific ethnography, Indigenous astronomy, social-political tribal structures, culturally congruent instructional strategies, and indigenous science philosophies. Most of his work in recent years has focused on community engagement to understanding shifts in an Indigenous paradigm of research for science knowledge production. This work has included extensive collaboration with tribal knowledge holders across Native communities and Indigenous academic scholars at institutions nationally and internationally.

Dr. Curtis Suttle (FRSC, Distinguished University Scholar) is a professor in the Department of Earth, Ocean, and Atmospheric Sciences at the University of British Columbia. Dr. Suttle was recently interviewed in the CBC radio show North by Northwest and discussed his research on how viruses are essential to our existence. 

Research in the Suttle laboratory is primarily focused on viruses and their role in the environment. The work ranges from the characterization of viruses isolated from the environment to quantifying the role of viruses in microbial mortality and nutrient cycling. The techniques employed range from nucleic-acid sequencing to oceanographic sampling. Some current projects are examining viruses and their roles in the oceans, high Arctic, deep mines, aeolian dust, lakes and migratory-bird ponds.
