Notes: This will be leg 2 of 2 trips to survey the full extent:
Sub FANs:
17BIM05 = R/V Sallenger - SBB + chirp
17BIM06 = R/V TwinVee - SBB
17BIM07 = R/V Shark (White = WVR1) - SBB
17BIM08 = R/V Chum (Blue = WVR2) - SBB
Entries for this field activity are based on entries from Field Activity 2017-323-FA
Location:
Leg 2: Western Chenier Plain
