Her PhD, supervised by George Knox at the University of Canterbury,[4] developed new observations in copepod taxonomy but also produced insights into the processes affecting zooplankton in Kaikōura submarine canyon.[5] Her pioneering research in this canyon provides a baseline for the biological and physical changes associated with the 2016 Kaikōura earthquake.[6]
She participated in the Ross Ice Shelf Project expedition to the central Ross Ice Shelf. The team successfully bored through the ice shelf in 1977 to retrieve data and samples in the ice shelf cavity.[8]
Publishing under surnames Grieve, Bradford and Bradford-Grieve, she has made a significant contribution to the fields of biological oceanography in New Zealand and internationally.[10] She is responsible for some of the first measurements of open ocean productivity in New Zealand waters.[11] Her research has extended from the subtropics to the Antarctic/Southern Ocean. She has researched topics such as ocean food webs and ecology, and is regarded as the global expert on copepod biosystematics.[12]
Grieve was a key researcher involved in the environmental survey work that underpinned and guided the development of the Maui oil and gas production facilities within the Taranaki Bight.[13] This was one of the first marine developments to consider detailed environmental management. In addition she was also on the Task Force group responsible for reviewing the NZ Fisheries Legislation in 1991–92.[14]
In 2017, Grieve was selected as one of the Royal Society Te Apārangi's "150 women in 150 words", celebrating the contributions of women to knowledge in New Zealand.[1]
