Dr Jonathan Tyler
Dr. Jonathan Tyler is a senior lecturer in the Department of Earth Sciences with a PhD from University College London and research experience from the Universities of Tokyo, Oxford and Melbourne. His teaching and research revolve around climate variability past and present and the way Earth surface processes can be deciphered using chemical signatures.
When not working, Jonathan is being re-educated about the world via his two young children. He tries to spend as much time as he can outside, but otherwise indulges in following the travails of the English cricket team whilst listening to '90s alternative rock.

I am a palaeoclimatologist and isotope geochemist. That means I am interested in past climates and the use of chemical tracers in sediments to develop our understanding of past climate changes. I mostly work with lake sediments, but am branching out to work with marine and cave deposits.
Mainly, I'm interested in developing the tools used to reconstruct past climates through field and experimental studies on modern systems. Recently, my focus has been on the last 2000 years of climate variability in southern Australia and on period known for the end of the last ice age (the last 50,000 years). I continue to work on projects aimed at understanding climate variability and landscape change in Antarctica, Japan and the United Kingdom.
During my career I have worked with a variety of techniques, both geochemical and palaeoecological, including oxygen and silicon isotopes in biogenic silica, carbon and nitrogen isotope analysis of sedimentary chlorins and branched GDGTs as a proxy for surface air temperature and soil pH. Recent projects involve the use of 'clumped isotope' palaeothermometry and sub-annual geochemical analysis of fossil and modern bivalves.
My work has involved sediment analysis, field monitoring of modern lake systems and experimental analysis of diatoms and haptophytes (siliceous and calcareous algae) in culture. I am increasingly concerned with the numerical analysis of sedimentary timeseries and contemporary data, and have recently conducted a large scale data synthesis of Australian climate records for the last 2000 years.

Earth Systems I (GEOLOGY 1103)
This course draws from all fields of geoscience to explore the evolution of Planet Earth. My lectures introduce students to the energy balance on Earth, the fundamentals of atmospheric and ocean circulation and their effects on the hydrosphere, cryosphere and biosphere.
Geochemistry II (GEOLOGY 2505)
This course focuses on the chemistry of the natural world and the chemical evolution of the Earth over geological time. I coordinate this course and my lectures include the partitioning of elements on Earth, low temperature geochemical processes and the fundamentals of stable isotope geochemistry.
Earth Systems History III (GEOLOGY 3505)
This course focuses on the chemistry of the natural world and the chemical evolution of the Earth over geological time. I coordinate this course and my lectures primarily cover climate variability during the late Cenozoic and Quaternary up to present day, including the various techniques used to reconstruct climate change over those timescales.
Structural Geology II (GEOLOGY 2501)
This year (in 2016) I'll be joining my first Pichi Richi field camp with Structural Geology. I'm really looking forward to spending a week out in the Flinders Ranges, and being part of one of Adelaide's longest running geology traditions.
Principles and Practice of Research II and III (SCIENCE 2300 and 3100)
I regularly contribute to the PPR courses for the BSc Advanced program, leading tutorials and supervising research projects.
