Gardline have run 5 marine mammal and turtle identification and observation techniques training courses (2x 2010, 2x 2013, 2017 and 2018), training over 50 people from TGL and Navy. The 2-3 day training course covered basic acoustics and its effect on marine animals, marine mammal and turtle ID and behaviours, completing sightings forms and observation and monitoring techniques.
Opportunistic data was collected by TGL and Navy personnel working on offshore platforms and security vessels. Observations were conducted in conjunction with monitoring for other objects e.g. fishing gear.
In the event of a marine animal sighting, observers completed a standardised form including the date and time, vessel position, species identification, number of individuals, behaviour and details of features used to identify the animals. Where feasible, photographs were taken
Species identification was verified by Gardline Marine Biologists and a level of certainty given – definite, probable or possible.
