2015 - Dr Duan March - Auditory anatomy of beaked whales and other odontocetes: Potential for cochlear stimulation via a "vibroacoustic duct mechanism". Undertaken by Dr D March, 2009 to 2014 - soon to be published, one of our major projects is looking into exactly how odontocetes, that is toothed whales, hear. Cetaceans have many special adaptations that allow them to successfully survive and thrive in the marine environment, and one of these adaptions is their ears. Unlike humans, cetacean ears are inside their head and they use special acoustic fats in their jaw, rather than an external ear canal, to detect sound. Despite all we know about these animals, exactly how they hear is still a mystery to us. Without knowing this, we cannot predict how human based activities like shipping and sonar impact upon these animals. When you consider that these animals spend much of their time in environments of reduced light looking for food, hearing is pretty important. The project is a collaborative effort with various universities and government departments and is focusing on the anatomical variations of the ears between species.

Abstract - Computed tomography (CT) and microcomputed tomography (microCT) were used to examine the structures involved in cochlear stimulation in odontocetes and terrestrial mammals. Cranial CT examined the osseous attachment of the skull to the tympanoperiotic complex (TPC) and the path of the endocranial foramen of the vestibulocochlear nerve (EFVN), which was assumed to contain the perilymphatic duct. Additional CTs of TPC were taken postextraction to examine the gross morphology of this structure. MicroCT was used to examine the acoustic windows of the cochlea, including the round and oval windows and the apertures of the cochlear and vestibular aqueducts. Cranial CT scans demonstrated an osseous connection between the skull and TPC in beaked whales and Physeter macrocephalus. EFVN traveled through a greater length of cranial bone and communicated more closely with the periotic bone in beaked whales than in other species. Ziphius cavirostris was observed to have a reduced medial sulcus of the mallear ridge (MSMR) and tympanic plate and an enlarged aperture of the cochlear aqueduct, respectively. The potential significance of these findings, including the role of the perilymphatic duct as a novel route of cochlear stimulation referred to as the "vibroacoustic duct mechanism", are discussed.

2012 - Garry Aitchison - The Impact of Response Expectancies on Heart Rate Variability in a Human-Dolphin Interaction - Abstract -Swimming with a captive dolphin is believed to generate an increase in an individual's subjective well-being. This study tested that relationship and evaluated the relationship between wellbeing and heart rate variability associated with a paid dolphin encounter. It was hypothesised that a change to heart rate variability resulting from the dolphin encounter would be predicted by the strength of belief the individual held about dolphins and by the individual's predicted emotional reactions to the encounter. Beliefs about dolphins were shown to be an important predictor of change to heart rate variability. Contrary to expectations one category of dolphin vocalisations also proved to be a significant predictor of change to heart rate variability.

Curtin university

Dolphin Marine Conservation Park worked with a Curtin University student in a project over several years to determine if the whisker patterns of Australian Sea Lions change over time. It is hoped that the results from this project will allow researchers studying the endangered Australian Sea Lion in the wild to identify seals on the beach by their whisker patterns rather having to catch and tag wild seals.

'Modelling energectics of fur seals and sea lions'

A study through Macquarie University which examined the metabolic rates of seals (DMM collection) as they dive and swim. In this study staff from Dolphin Marine Conservation Park trained our seals to swim underwater for several minutes before surfacing and breathing inside a plastic bubble for 10mins. By measuring the amount of CO2 exhaled by the seals after their swim the researchers have been able to determine the difference in the metabolic rates between resting and swimming seals. In the real world, this information can be used to determine the energy needs of wild seal colonies and this information can then be used to ensure we protect enough fish stocks around the seal colony so that the seals have enough to eat!

2018 - Dr Duan March - Dolphin Marine Conservation Park veterinarian, Dr Duan March is currently completing a PhD investigating sea turtle health with partners from Taronga Zoo, Seaworld, Southern Cross University and James Cook University. The article looks at how useful current blood reference intervals are at describing sea turtle health and suggests some ways that we might be able to improve the way we treat these animals when they come in for rehabilitation.

Witsel (eds.), Rising Tides and Sea Changes: Adaptation and Innovation in Tourism and Hospitality: Proceedings of the 25th Annual CAUTHE Conference, Gold Coast, Queensland, 2 - 5 February 2015, Southern Cross University: Gold Coast.

The Abstract for this paper is:

This paper contributes to the development of effective survey and analysis processes to identify and better understand the relationship between experiential components, tourists' environmental perceptions and behavioural outcomes resulting from wildlife tourism experiences. Results are presented in relation to a means-end data collection and qualitative analysis process involving the use of Leximancer, comparison to a recently developed ecotourism model, and participants' intentional behaviour changes resulting from a captive dolphin experience. The results demonstrate cognitive links between the perceived benefits of environmental awareness, values of appreciation and global perspectives of personal significance leading to insights of environmental concern and responsibility. These are linked to intentional post-experience environmental behaviours involving lifestyle changes. This knowledge is essential to develop and evaluate tourism programs that inspire participants' concern and positive environmental behaviours, and addresses a gap in the tourism literature comparing captive and 'natural' wildlife interactions with regard to their contribution to environmental sustainability.

2014 - ongoing and not yet published - Investigation into the epidemiology of sea turtle stranding patterns along the NSW north and central coast of NSW

Dolphin Marine Conservation Park is working with the National Marine Science Centre of Southern Cross University and honours student Tegan Baker to investigate the patterns of sea turtle stranding events along the coast of NSW. Dolphin Marine Conservation Park is supplying the stranding data and biological samples so Tegan can investigate the links between weather events and pollutants within the environment on sea turtle health. With some luck and a lot of hard work, hopefully the project will lead to improved environmental monitoring and regulation that will benefit all marine species in the near shore coastal environment, including our threatened species of sea turtle.

2012 - Jacinta Ryan - Whistle production of a female bottlenose dolphin (Tursiops aduncus) before, during and after birthing. Unpublished Masters Project Report. School of Environment, Science and Engineering, Southern Cross University, Lismore. Environmental Research Project prepared as partial fulfilment of the requirements of the Master of Marine Science.

Abstract: The aim of this study was to examine the whistle production within specific behavioural contexts of a captive birthing female bottlenose dolphin, Tursiops aduncus, and her non-birthing female companion before, during and after a birthing event. Variations in whistle parameters, whistle use and social interaction were investigated to identify specific trends in order to determine the effect of the birthing process on whistle production. Whistle diversity, whistle rate and acoustic parameters were examined for each whistle emission. Acoustic parameters which were used to identify and catalogue distinct whistle types included tonal class, duration, start time, start frequency, end frequency, lowest frequency, highest frequency, peak frequency, the number of loops, breaks, and harmonics. During the birthing phase whistle rate increased by more than 30% and whistle diversity decreased in comparison to the non-birthing phases. Distinct signature whistles were identified with favoured whistles being dependent on birth phase. Behaviour was recorded with each whistle emission adding context to our results. This study is the first to quantify changes in the whistle emissions and behaviour of Tursiops aduncus before during and after a birthing sequence. By monitoring the changes in acoustic emissions and behaviour during the birthing process indicators related to homeostatic imbalance associated with 'stress' may be identified. Understanding how bottlenose dolphins use sound will lead to a greater understanding of dolphin welfare and ecology and aid in their protection and conservation.

This was my last visit to The pet Porpoise pool 35 years ago I was 7. we used to go every year when I was little and my grandmother getting kissed by a seal was the highlight of the day. I loved feeding the fairy penguins and my dream is to one day swim with the dolphins. I would love to win passes to marine magic to experience it again with my family. What great memories Katherine, we hope to w..


My mum and I just spend the whole weekend at Pet Porpoise Pool, we travel from Tweed to Coffs just to see Buck and Zip, we love them and can't get enough. Already driven down 3 times this year, and every time it's amazing. And we loved seeing all 5 dolphins in the pool, Bella's a sneaky little thing! We got drenched by her plenty of times hahaha. Great to hear you enjoyed yourselves - Paige S..

My family with two teenage children travelled from Port Macquarie to visit on 15th July because my daughters school camp to Coffs Harbour was cancelled and the one thing she wanted to see the most was the Dolphin Marine Conservation Park. We arrived late so didn’t see the dolphin show but absolutely loved seeing the seals, dolphins, penguins and other marine life with their daily goings on. We..


I was a junior marine ranger for the whole day and it was such an incredible experience, it is definitely worth coming and having a look at, and even if you are not a junior marine ranger it is still mind blowingly awesome, one of my favorite moments there was being able to see the dolphin show and also being able to pat the dolphins belly, my favorite dolphin is Calamity because she is really..
