Description: DNA DIVERS - global eDNA citizen science project [grant submissions closed but other sites welcome]
This is an exciting opportunity for interested / motivated divers to participate in DNA Divers—a citizen science project that connects recreational divers with marine researchers to explore underwater biodiversity using environmental DNA (eDNA).
Using our research contacts and Professor of Marine Biodiversity at Liverpool John Moores University, Stefano Mariani, DNA Divers empowers volunteers to help shape and drive marine research. Using a device called the metaprobe, divers collect trace DNA left behind in the water by marine life—no lab experience or training needed. The unique part: volunteers will help define the research questions, choose dive locations, and collect samples.
We have already assembled a list of sampling locations where our communities could collect eDNA samples, following into a grant application due in June.
However, we welcome other applications and expressions of interest from anyone wanting to get involved!
What we are looking for, and what you need:
• Special or underexplored dive sites
• Sampling plans that can happen within 12 months
• Willingness to work independently with basic materials
• Feel free to recommend aspiring citizen science / scientific divers in
your network as well
• Access to a 3D printer, bleach, falcon tubes, etc.
Please note: this is a fully autonomous citizen science initiative. Materials and equipment are not provided, but you will receive complete protocol documentation and guidance after you have registered initial interest. Please see Jenn or Erik for more information, and to get the sampling list and instructions.
Certification requirement: Rec 1 or Fundamentals

Date: July 6, 2025 to July 13, 2025
Description: The shores of the island of Krk feature beautiful rocky reefs, steep walls and shallow seagrass meadows. These underwater water ecosystems suffer from multiple anthropogenic impacts from anchoring activities to lost fishing gear and traps. With a group of GUE divers we started to document the beauty and damage of these habitats in 2024. In 2025 we want to take it a step further and explore restoration possibilities of remaining seagrass meadows in the shallow waters. At the same time the deep reefs feature an abundance of gorgonians that we try to support in regaining strength by removing entangled fishing gear and remove necrosis areas from the animals caused by this gear.
The work of the GUE divers is tying in with a University program that teaches young ocean scientists in this locations. The different courses can pick up the datasets and samples collected by the GUE project, but also provide high resolution 3D bathymetry, species lists and potential points of interests and in that way build an exciting and rewarding synergy.
If you have any questions if this project is what you are looking for, please reach out to Erik via erik@gue.com.
For first hand experiences from our participants in 2024 please have a look into our article in Quest Vol. 25.

Event website: https://divehouse.pl/en/event/baltic-wreck-week-2025-dive-house-baltic/
Date: July 16, 2025 to July 20, 2025
Description: This trip is a great way to get experience in wreck diving in the Baltic Sea.
The main goal is 5 days of fun dives but we will also make some micro-project activities and workshops for those who are interested :)
The Polish coast witnessed many sinking ships and warships. These sinkings were associated with war operations but many vessels also sank as a result of collisions or severe storms.
It is estimated that between 10,000 and 100,000 shipwrecks lie at the bottom of the Baltic Sea! Many of these are poorly documented. Many of them are still waiting to be discovered….
Thanks to the unique environmental conditions, waters of the Baltic Sea perfectly preserve wood. As a result, even the oldest wrecks lying at the bottom of our sea are still in an excellent state.
We plan for a week of wreck diving at recreational level (up to 30m) addressed to all GUE divers.

Contact: GUE Sweden, info@guesweden.se
Event website: http://guesweden.se
Date: July 16, 2025 to July 19, 2025
Description: The purpose of the project is to serve as an extension of the work conducted by 8+fjordar by enabling the inventory and documentation of ghost lobster pots in underwater areas that are otherwise inaccessible to them. The project also explores the potential for divers to lift these pots to the surface using lift bags, with a boat on the surface collecting them.
This project focuses solely on the documentation of ghost lobster pots rather than their recovery. Divers will identify and document lost lobster pots to better understand their locations, conditions, and impact on marine environments. The goal is to create a detailed record that can support future recovery operations and environmental protection efforts. By gathering this data, the project contributes to ongoing initiatives to combat ghost fishing and its ecological consequences.
It is crucial to approach it with an open mind and flexibility regarding all forms of participation.
Requirements to participate is GUE DPV1 as we are covering larger areas compared to diving without DPV.

Event type: Project
Location: Marine quest, Eyemouth, Scotland, United Kingdom
Event website: GUE North England
Date: July 16, 2025 to July 20, 2025
Description: As many of you know, the northern regions of GUE UK have of recent years had a home/base for most of its diving at the fantastic venue of Marine Quest, run by Iain Easignwold. Following some recent survey data made publicly accessible via an app called "Navionics", a possible location has arisen for the SS Maystone, sitting in 85m of water.
About the vessel:
Empire Wapping was launched 15/03/1945 and later completed May 1945. Being commissioned by Grangemouth dockyard company, Grangemouth for the Ministry of war transport - Stone & Rolfe Ltd, the ship's purpose was to be a general cargo ship.
The vessel measured a length of 281.6ft, breadth 40ft, depth of 13.9ft and had a tonnage of 2025-Ton. She was propelled via a single screw, and powered by a triple cylinder steam engine which gave an estimated speed of 12 knots.
In 1947 the vessel was sold to Thomas Stone Shipping LTD of Llanelly, Wales. Adopting her new name of SS Maystone, the vessel would remain in service until a tragic accident somewhere in the region of 4-5.2nm NNE of Longstone Lighthouse, Farne Islands. During a night of foul weather 18/10/1949, the ship was involved in a fatal collision with the Royal Navy aircraft carrier HMS Albion. HMS Albion was a 22,000-Ton Centaur-class light fleet carrier of the Royal Navy. The ship was laid down in 1944 and launched in 1947 but did not enter service until 1954. Badly holing the hull of the aircraft carrier during the collision, she was later towed into Rosyth under the steam of two tugs. The yet to be complete carrier nearly sunk under tow off the coast of St.Abbs head before making it to safety for repair. SS Maystone lost all but 4 of her crew members during the collision, giving a total loss of 20 sailors.
What makes SS Maystone a worthy project target?
Not only is this quite a large wreck to have only been discovered in late 2023, but I believe it could be the only ship in UK waters to have ever been sunk by a aircraft carrier, which makes it a super cool story. To date, there has only been 1 dive team visit the wreck. Following their dive, there has been no formal identification of the wreck, only presumptions and guesstimations that it is the SS Maystone. As mentioned before, the wreck rests in 85m of water and lies twisted with her stern section on its side, and as you move towards the Bow the hull becomes more inverted.
Project Objectives:
First and foremost I'd like the team to verify/confirm that this is the wreck of the Maystone, as there is another wreck in the vicinity which is yet to be identified. There has been no bell found on the wreck, so this could be an objective for one team on the project. I'd also like to document the wreck in the form of photogrammetry and video, with the aim of producing a video around 5 minutes duration. I would also like to use this project as a stepping stone, as there has been continuous sonar data collection around this particular area for quite some time now for infrastructure for the renewable energy sector. With growth in mind, I'd like to expand the project in the coming years with the hope of moving towards an area called Farn Deeps, where an excess of a dozen unidentified wrecks lie.
