2023 Hochstetter Lecturer:
Lorna uses sedimentological observations to disentangle physical processes in the deepest depths of the ocean. In the last decade she has worked on modern and ancient marine sedimentary systems around Aotearoa-New Zealand. As such, she is one of our rare specialists whose work simultaneously bridges terrestrial outcrops and deep ocean deposits.
In the last 6 years she has used cores from across the Hikurangi Subduction Margin to understand links between sediment deposits, dispersal pathways, and flow triggers, including earthquakes and large storms. Her Hochstetter lecture titled ‘Kaikōura Earthquake – Tales from the seafloor’ will share an exceptional and novel seafloor dataset that showcases the devastation wrought on the seafloor by the 2016 Kaikōura Earthquake, and the physical and biogenic processes in the minutes, hours, and years following the event.
Lorna is also currently leading a large team of 20 international and national researchers as part of a Marsden project on understanding the connections between glacio-climatic change, volcanism, and earthquakes over the last 1 million years. This work will form her supporting lecture titled: “Does climate influence the frequency of volcanism and earthquakes?”
Hochstetter Lecture tour dates
Details of Lorna's nationwide speaking tour will be posted on the Events section of the website.
Dates will be added as the details are finalised.

Ferdinand Ritter von Hochstetter
Christian Gottlieb Ferdinand von Hochstetter (1829-1884) joined the Austrian Geological Survey in 1853. Four years later he was appointed geologist on the Austrian frigate Novara on an expedition to circumnavigate the globe. The Novara berthed in Auckland in 1858. At the request of the New Zealand Government and supported by the Auckland Provincial Council, Hochstetter, accompanied by Julius Haast and others, surveyed the Drury Coal Field to the south.
This was accomplished so successfully that the provincial council persuaded the commander of the Novara to allow Hochstetter to remain in New Zealand to undertake further work in the province. Over the next five months Hochstetter and Haast, along with a support team, visited much of southern part of Auckland Province, including the volcanic region and the gold diggings at Coromandel Harbour.
On completion of his Auckland mapping, Hochstetter was commissioned by the Nelson Provincial Council to report on the mineral wealth of the province. Hochstetter, accompanied by Haast, arrived in Nelson on 4 August 1859. In Nelson, they examined Dun Mountain, from which he collected and subsequently named dunite, the Aorere Gold Field and other places of interest.
Hochstetter left Nelson for Sydney on 1 October 1859, on the first leg of his return voyage to Europe. Although he never returned, Hochstetter retained a life long enthusiasm for New Zealand. He maintained a correspondence with Haast and other New Zealand friends. His contributions to New Zealand are commemorated by several place names, and by names of many New Zealand organisms.
Hochstetter was the first to describe and interpret many features of New Zealand geology. His geological maps of Auckland and Nelson were the first of their kind in New Zealand.
