MOON JELLYFISH BLOOMS IN PRINCE WILLIAM SOUND     

Ever felt like you were visiting another world?!  Moon Jellyfish blooms (aurelia aurita) or aggregate jellyfish blooms occur every summer along the coast of Alaska.  Port Fidalgo in Prince William Sound offers the clearest water in the area, free from silt and glacier runoff so that divers can get a extreme view of just how massive these blooms get get in size.  Ranging in the thousands, these jellyfish don't sting and congregate in huge numbers to reproduce.  They are a carnivore, often feeding on small zooplankton.  Found almost always blue in color, some will be lucky enough to see a purple one.  If so, you've just spotted the female surrounded by endless males jocking for position with her.  One very unique characteristic of jellyfish blooms around the world is the fact that is doesn't happen very often or under conditions that allow for pre-planned trips to catch a bloom in the act.  However, we are extremely lucky to say this is one very dependable tour that is offered at Ravencroft.  The trick is spotting them as we travel to dive sites.  When I hear someone say, "hey, it looks like there is an island under the water over there".  Thats a telltale sign there's a jelly smack just under the water.  And it seems with the raising water tempertures in Alaska, we are seeing more and more blooms each year.

During this explosion of jellyfish, both divers and snorklers can swim in these vast migrations.  These blooms usually appear on the surface of the water and allow snorkelers the chance to swim on the surface, while divers will sink down mid column.  The blooms can reach hundreds of feet so there's plenty of space to get a shot free from other divers.  This is a extremely unique adventure and there are but a handful of area's in the world where jellyfish congregate like this, but nothing truley like here in Alaska!

 Along with Moon Jellyfish, the Lions Mane Jellyfish is another beautiful species to photograph. But divers beware, these one’s sting.  Although not deadly, they will leave you with a sting hurting like a bee might hurt.  The bells are harmless, but the trailing tentacles that can sometimes reach 15’ or more can sometimes be hard to see.  So, make sure to swim around the front and stay away from the rear of this orange invertebrate.

Diving along the coast of port fidalgo

There are many sites to visit along the coast of Port Fidalgo.  Some will offer fields of plumose anemones while other area's will be walls covered in small invertebrate life.  Make sure to scan the floor bottom because these area's are home to flounder and halibut that can easily hide in sand only inches from your hand.  We'll also visit known area's where giant pacific octopus hang out.

The Viking is great for small groups and is considered a wet cabin allowing divers to enjoy accessing the heated cabin while waiting for the next dive.  It is a 32' catamaran with dual Yam outboard's.  The cabin is equipped with full electronics, bathroom, heat and seating for up to 7 comfortably.  AED & Oxygen medical kit, Life-raft, first aid and all emergency equipment stored inside vessels cabin.  Captain is CPR and first aid certified.  Divers will have tanks filled with lodge's on shore dive compressor.  We end the day at 2pm in order to ensure enough time is given to fill scuba tanks.  During dive sessions, we use the "buddy system" and do not offer "in water" dive guides, but do give you a detailed briefing so that you can confidently navigate the site with a buddy.   If your group would like to request a dive guide, one can be provided for an additional cost but must be booked at the same time you book your stay.
