The IMarEST marine science activities will seek to incorporate a means of collecting and disseminating information on all aspects of marine sciences including the following:

Ballast Water, Communications and Navigation, Diving, Environmental Assessment, Fishing and Aquaculture, Geology, Hydrography, Marine Biology, Marine Biotechnology, Marine Mineral Resources, Marine Pollution, Meteorology, Ocean and Ecosystem Modelling, Oceanography (Physical, Chemical and Biological), Oceans and Climate, Offshore Oil and Gas, Renewables, Seabed Mapping and Subsea.

• To provide a more interdisciplinary all-embracing approach to marine science. Integrating developments in the marine science sector with the institutes work in the engineering and technology field.
  
• To provide focal points for communications between marine scientists both centrally and locally, assisting in the exchange of knowledge and the advancement of expertise and experience in the field. Focal points will include the Institute’s website, e-marine newsletter, Marine Science magazine and the Journal of Marine Science.
  
• To arrange or to support a series of meetings, conferences and seminars in order for marine scientists to meet and assimilate ideas.
  
• To provide a vehicle for Continuing Professional Development (CPD) and to uphold and further the expertise, quality and status of Group members working in the field. To develop, maintain and publicise a register and database of approved scientists.
  
• To cooperate and develop relationships with industry, academia and professional bodies.
