What this video covers
Brupeg makes a 500-mile passage south through the Great Barrier Reef, stopping at Howick Island to retrieve a GPS tracker for Tauranga Blue before continuing to Cairns.▶ 0:00 Navigating between Flinders Island and the mainland, the crew spots hundreds of sediment slicks on the surface — post-cyclone wet-season runoff, not coral spawn — and notes that geolocated mast-camera footage of these events can supply universities and environmental agencies with reef runoff data.▶ 3:12 At Howick Island, GPS positions for the ghost net and FAD diverge between Google Maps, Navionics, and OpenCPN, so the crew launches the dinghy at high tide to search the windward shore on foot.▶ 12:17 They find rope and debris wrapped around trees but no intact net.▶ 17:53 On the return dinghy run, a large shark tracks them before veering off to chase a turtle, forcing a hasty retreat to Brupeg.▶ 19:18 A beach cleanup follows under drone surveillance for crocodiles.▶ 19:49 Coastal landslides from Cyclone Jasper — reportedly three metres of rain in 24 hours — are visible as the boat moves south.▶ 23:09 The crew anchors in the lee of the silica mine at Cape Flattery before the next leg to Cooktown.▶ 23:09
