Mud deposits record important information about Earth’s surface environments, and are usually associated with deposition in calm water. Recent laboratory experiments, however, demonstrate that mud can accumulate at high flow velocities, yet this has not yet been recorded from modern estuaries.
The proposed study will overcome this problem by combining oceanographic measurements with sediment coring to link the hydraulic processes and depositional record of mud in the Firth of Thames, North Island.
The results will be used to develop new mud depositional models that will fundamentally shift how the sedimentary record is interpreted to better understand Earth’s geological past.

Harold Wellman (1909-1999) was a scientist unrivalled in the remarkable contribution he made to our understanding of New Zealand earth science. He had a varied and colourful early career as a gold miner, surveyor and geophysical survey assistant. In 1937 he joined New Zealand Gological Survey's coal resources survey in Greymouth, which began his most productive period of research. His intense geological debates with colleagues at the bar of the Albion Hotel in Greymouth are now legendary.
Harold is best known for his recognition of the Alpine Fault, but his major contributions to advancing New Zealand earth science are many. They included establishment of the New Zealand Fossil Record File, recognition of major displacements of rock in Northland, development of biostratigraphic stages for subdividing the New Zealand marine Cretaceous based on field observations and collections of fossil Inoceramus.
In the mid-1950s Harold had a short stint with British Petroleum in Gisborne before taking a position in the Geology Department at Victoria University of Wellington in 1958, an attachment he maintained even after his retirement in 1974. Harold's international reputation in pioneering structural and tectil tonic geology was highlighted in a 1992 BBC Horizon documentary on him, titled "The Man that moved the Mountains."
Harold and his wife Joan provided the funds for the first Harold Wellman Prize for an important fossil find, because in the 1980s he felt that the role of paleontology in geology was losing its former significance. In 1998 they established the Wellman Research Awards to assist young geology researchers.
