- Data taken from the following collection and validation protocol : Methodological guide to observing marine mammals and birds in the France’s mainland coastal waters and adjacent areas – PACOMM – SAMM Programme . G.Dorémus et al. 2011.

- The acquisition protocol for this data on these campaigns was implemented thanks to the experience of the team from the PELAGIS observatory gathered over more than 10 years in the field, and notable through the aerial observation campaigns ROMER( 2000-2002), ATLANCET (2003) and SCANS (2005)

Observations are made from an aeroplane flying over predefined transects at a constant altitude of 600 feet and a speed of 90 knots. Two observers record the environmental conditions and the following observations (at the surface or below the surface):

- Using the strip transect method (200m strips): bird observations

- Using the line transect methods (up to 500m): observations of matine mammals, sharks, rays, bony fish (large fish or shoals of fish) and sea turtles.

- Using the strip transect method: macro waste (200 m strips) and boats (500m strips)

Data is collected and coordinated by the PELAGIS observatory by scientific teams and observers, all of whom are specifically trained in aerial observation protocol (identical protocols for REMMOA and SAMM).

Balance sheet :

SAMM campaigns have made it possible to collect over 20,000 pieces of data of the same type in France’s mainland waters along over 100,000 km of transects.

REMMOA campaigns have made it possible to collect over 58,000 observations of marine megafauna and human activity (waste, vessels and fishing gear) over nearly 205,000 km of transects travelled by plane over the sea.

- flyovers in mainland France – SAMM campaign (Aerial Marine Megafauna Monitoring) – are conducted in the context of the PACOMM programme in order to meet community objectives for conservation and the promotion of maritime areas (Natura 2000, MSFD, regional maritime conventions, etc.).

The dataset is made up of two datasets: samm1 for winter 2011 and samm2 for summer 2012.

Data collected within the framework of scientific research for the implementation of the Natura 2000 network at sea. The operational phase was conducted jointly by UMS 3462 for scientific coordination and by the Marine Protection Agency for the overall coordination of the project.

- Flyovers conducted in overseas territories – REMMOA programme (Monitoring of marine mammals and other pelagic megafauna by aerial observation), made up of four diversity and density mapping campaigns for pelagic megafauna in the EZE of French overseas territories (West Indies, French Guyana, Indian Ocean commission area, French Polynesia and New Caledonia) – aim to add to scientific knowledge (which is abundant and diverse in coastal areas) in the vast swathes of open ocean which make up the majority of French EZE in tropical areas of the Atlantic, Indian and Pacific oceans in order to identify the priority sectors for establishing news Marine Protection Areas and to draw up management programmes.
