In our first dive we have our team had five buddy pairs, the survey area was divided using five transect lines and the survey was conducted systematically. During the dive a big ghost net and an area with lots of interconnecting old ropes and nets were discovered by two different buddy teams. Both area were marked and during our second dive our whole team revisited and cleans these areas.
