GLSPS Meetings Announcement
All Meetings are now on "Zoom"

Please Join us for a GLSPS Meeting!

Become A GLSPS Member


The COVID-19 Outbreak has effected most of us throughout the world.  Social distancing, "Stay at Home Orders" from Local, State and Federal Governments and lack of communications among the masses have pushed us to seek out other means to communicate.  With the advent of Online Meetings from "Zoom" "Google", "Microsoft" and others, it has bridged the gap between social visiting and conducting every day business.

Currently the GLSPS Board of Directors is choosing to stay with the Zoom Online Meeting System until further Notice.  With the lifting of restrictions and vaccines, many businesses and meeting formats are starting to meet in person once again.  The board is in the process of deciding how we conduct our board meetings in the future.  We were possibly thinking about meeting in person every other month or every quarter.  When we do decide to meet in person we will still have a highbred version like we had before the pandemic.  We have Board of Directors that are in other cities and states and will still need to participate in the Monthly Board of Directors Meetings via Zoom.

Please join us for a “Zoom” Online Meeting.  All of the GLSPS meetings are broadcasted and have been since February 2019.  Please join us by logging in as a member.  Then going to the “Events Calendar” Click on the date of the meeting and scroll down to the description of the meeting where you will find the link and any information you need for the "Zoom" Meeting.  Click on the link and you will be prompted to download the most current and secure software for the GLSPS Zoom Meeting System.  This will only happen once, (unless there’s a software update).  Once the software is loaded it will automatically go to the Zoom meeting login, enter the password, (which is in the meeting information) push enter and you will see the participants and the meeting in progress.  Your audio will be muted upon arrival to the meeting and you can toggle it on and off as needed.  You will mostly be muted during the meeting.  You can also toggle your video on and off during the GLSPS online meeting.  Please feel free to use the "Chat" option to ask any questions or make any comments during the meeting.

It's very simple to join us and stay in contact with the GLSPS Board of Directors, Staff and fellow members.  The online meetings will help keep members up-to-date and informed about the organization's future, happenings, goals and ideals.  

The GLSPS will continue to broadcast ALL meetings from now on, even after the COVID-19 Outbreak has been cleared. 

Please do not hesitate to join us during any meeting we broadcast.  Please check the Events Calendar for meeting availability.  What better way to become more active as a GLSPS Member! 

We hope to see you at the next online meeting!

3D Shipwreck - Photogrammetry


J H Jones

The Great Lakes Shipwreck Preservation Society Thanks to Ken Merryman and his circumnavigating adventures he was still able to continue with the 3D Photogrammetry Process we set up over the years

Our GLSPS divers aboard the "Heyboy" have performed the necessary dives to shoot the images to create the 3D models.

We have added a few more 3D Shipwreck Images to the GLSPS 3D Photogrammetry Database.  Please feel free to take a look at the database by clicking on the link to the 3D Shipwrecks Website. 

In the future we hope to add more 3D images to the Database.
