Fig. 1: Conservation interventions with deep active hydrothermal vents in relation to their biogeographical provinces.
From: Towards a global strategy for the conservation of deep-sea active hydrothermal vents

Map illustrating the conservation interventions, such as area-based and regulation-based management measures, adopted for deep active hydrothermal vents worldwide. Numbers correspond to the order of establishment; lower-case letters indicate discrete Area Based Management Tools (ABMTs) in the same region. EEZ Exclusive Economic Zone, ECSC Extended Continental Shelf Claim. Some area-based management measures might not be visible due to the Mercator projection distortion or to the size of the ABMT.
