Training MMOs since 1996

Marine Mammal Observers (MMOs) monitor the presence of marine mammals during activities such as geophysical surveys (e.g. seismic surveys used in the exploration for oil and gas) and construction projects (e.g. offshore wind farms, harbours, bridges, etc.).  They provide advice to ensure that operations comply with relevant guidelines to reduce the risk of injury or disturbance to marine mammals. 

Carolyn Barton has been training MMOs for two decades and is approved by the Joint Nature Conservation Committee (JNCC) and Bureau of Ocean Energy Management (BOEM)/ Bureau of Safety and Environmental Enforcement (BSEE). Carolyn is the only trainer who has been involved in the development of the JNCC guidelines, has designed the JNCC recording forms and has regularly analysed MMO data to assess the effects of seismic airguns on marine mammals and examine the operation of the guidelines; she is also an experienced MMO.  This breadth of experience enables the delivery of high quality training about the role of the MMO and the practical operation of the guidelines. Regularly updated to reflect current practices, these short-duration but intensive courses present an affordable but high quality option for MMOs.

JNCC-recognised MMO course

MMOs in the UK are engaged on geophysical surveys, pile-driving and explosives operations, and increasingly also for other operations such as cable-laying or dredging. It is a prerequisite for all MMOs working in the UK Continental Shelf to have been trained on a course recognised by JNCC.

In the US Gulf of Mexico, Protected Species Observers (PSOs) monitor the presence of marine mammals and sea turtles during geophysical surveys.  The BOEM/ BSEE mitigation measures require that all visual observers in the Gulf of Mexico have completed a PSO training course.
