Speakers

Mr Pierre Almeida

Pierre is the International Sales Manager of Ocean Sonics. He graduated with an Advanced Diploma in  International Business from NSCC and attended Dalhousie for Computer Science. Pierre has worked for  Ocean Sonics for over four years and has involved in many hydrophone array and ship noise monitoring  projects worldwide.

Dr Tik Sun

Dr Tik Sun is the managing director of Integrate System Ltd. He has obtained his PhD degree in Materials  Science in 2009. He has led many research development projects including ultrasound scanning systems,  pass-by noise measurement system, and components for telemetry products. He is at present providing  hydrophone product and relevant consultancy services for several hydrophone monitoring projects in mainland  China for institutions and Universities.

Seminar Highlights

Ocean occupies 70% of earth and is the largest ecosystem where living organisms inhabits. As  electromagnetic wave cannot propagate through water due to water’s high permittivity and conductivity, sound  become the major means for communication in ocean. Marine mammals have evolved to capitalize on the  efficiency with which sound energy travels through water. Anthropogenic and natural sound sources contribute  to ocean ambient noise, which can interfere with the use of this sensory modality by marine animals.

Anthropogenic noise sources have been increasing steadily over recent decades largely due to coastal  population growth, increased global transportation, and offshore industrialization. Understanding the potential  impacts of anthropogenic noise requires the establishment of ambient acoustic baselines and documentation  of individual marine mammals’ response to various kind of noise. Further, strategies of protection against  harmful anthropogenic noise to marine mammals need to be developed. In this presentation, technologies to  establish the ambient acoustic baselines and measures to protect marine mammals against anthropogenic  noise will be explored.
