[From David Benavente's LAOLAO Bay ICON Station Maintenance log -- July 5, 2012:]
Objective was to revisit the station and thoroughly clean SeaBird lens cleaner. David B had a scheduling conflict he joined the group later. On this visit Copper screens were replaced. They appeared to be punctured; the puncture marks looked as if they had come from a three prong spear, commonly used by fishermen.
