This event is created to give an opportunity to be able to become a member and dive off the GLSPS Research Vessel without being on a project.  It is a chance to see how the GLSPS engages in their projects aboard the vessel.

We are inviting GLSPS members to join us for this experience.  The fees that are associated with this event are $35.00 for members and $65.00 for Non Members becoming a member. 

The $60.00 for non members includes, food, air-fills between dives and a GLSPS "Crew" Membership.  

The $35.00 fee is only for current members to split food costs and air-fills between dives.  This also is sleeping aboard the RV Preservation if you desire.  If you are already a member, the fee will only be $35.00.  If interested, please register for this really cool event.

Important:  For all diving operations on-board the RV Preservation and following the GLSPS Protocol, all diving participants will need to print, read, understand and sign the Liability Release, Waiver and Medical Forms 24 hours before the event.  Here is the Link.  

GLSPS Master Liability Waivers - Medical Forms

Please Note:  If you answer "Yes" on any
questions in the Medical Form, you will need to fill out the second page of the medical form with a signature from your doctor that you are cleared for diving.  Please bring signed forms with you.  If we have to hand you the forms at the boat, GLSPS protocol based on the diving industries rules say that you are not able to dive.

The diving itinerary is listed below.

If you have any questions about the event, please contact Jack Decker.  Contact info below.

We hope to see a few familiar and new faces.
