First report of the season – diving with Guadalupe great white sharks.

Location: Ensenada, Guadalupe Island, Mexico. Well, the Nautilus Explorer arrived in Ensenada this morning precisely on schedule after a 6 day steam down the coast from Vancouver…  We set aside 4 days for a “mini-refit” in the shipyard and then we are off on our first trip to Guadalupe Island to dive with great white sharks.  I’ve been chatting […]

Dust Storms and Forest Fires

Super hot diving this morning with great white sharks

The diving is super hot this morning, with great white sharks continuously around the back of the Nautilus Explorer. The last day and a half were quiet with sporadic sightings (although our first afternoon was good), but the winds have died down and the white sharks are back with a vengeance.

Anchored right at a hot spot

Mauricio Hoyes and Dr. John Kelly, 2 of our favourite shark research scientists, have been out in the inflatable with a rotating crew of guests chumming and tracking the great whites. They managed to place a telemetry tag on a 3 metre male shark today and have been tracking it ever since.
