Geographical distribution of sea turtles observations between 1911 and 2011

All the data available for the English Channel and Atlantic fronts are collected by observers of the Réseau Tortues Marines français d’Atlantique (Marine Turtles Network for East French Atlantic) (RTMAE). For the Mediterranean, the majority of data are derived from observations of the Réseau Tortues Marines de Méditerranée française (Network of French Mediterranean Marine Turtles) (RTMMF). Data are collected in a standardized manner (data collection sheet) during interventions at the scene of grounding or voluntary reporting (harbor fishing vessels).
