Component decision tree for impacts on sea turtles. The key is followed to obtain a recommended suite of monitoring protocols.

Determine which impacts to sea turtles need to be monitored:
The energy resource is
Wind	Go to A
Tidal	Go to B
Waves	Go to C
(A) The wind turbine foundation is
Monopile OR tripod OR floating mooring	Go to A1
Lattice OR gravity	Go to A2
(A1) The stage of the monopile or tripod or floating mooring wind turbine project is
Construction	W1, W3, W4, W5, W8
Operation	W1, W3, W4, W5
Decommissioning	W1, W3, W4, W5, W8
(A2) The stage of the lattice structure or gravity foundation wind project is
Construction	W1, W3, W4, W5, W8
Operation	W1, W3, W4, W5
Decommissioning	W1, W3, W4, W5, W6, W7, W8
(B) The tidal turbine type is
Open OR shrouded bottom-mounted	Go to B1
Open OR shrouded floating mooring	Go to B2
(B1) The stage of the bottommounted tidal turbine project is
Construction	W1, W3, W4, W5, W8
Operation	W1, W3, W4, W5
Decommissioning	W1, W3, W4, W5, W6, W7, W8
(B2) The stage of the floating mooring tidal turbine project is
Construction	W1, W3, W4, W5, W8
Operation	W1, W3, W4, W5
Decommissioning	W1, W3 W4, W5, W8
(C) The stage of the wave energy device is
Construction	W1, W3, W4, W5, W8
Operation	W1, W3, W4, W5
Decommissioning	W1, W3, W4, W5, W8

Recommended protocols:

W1: visual surveys.

W2: passive acoustic monitoring.

W3: marine mammal observers.

W4: stranding response networks.

W5: tagging.

W6: underwater photography.

W7: SCUBA surveys.

W8: ROV surveys.
