Kees Beemster Leverenz, Underwater Imaging Software and Development


Kees is an enthusiastic local diver and GUE instructor. Global Underwater Explorers (GUE) is a scuba diving organization that provides education within recreational, technical, and cave diving. He enjoys getting in the water as often as possible. Kees is passionate about contributing to both local and global photogrammetry projects, as well as assisting with cave exploration projects in Mexico and Canada. In his professional life, Kees has a Bachelor of Science in geology from the University of Washington, and currently works as a software developer for Microsoft’s Office 365 Incident Communication and Coordination team. 

Although not often considered as a recreational diving hot spot, Lake Washington harbors some of the Pacific Northwest's best-preserved wrecks with stories stretching back a century. Cold water and low light has allowed delicate aluminum planes and wooden boats to remain preserved. The documentation of these wrecks is difficult, due to the low visibility and challenging conditions in this body of water. Kees has been using modern 3D documentation techniques and adopted software to render the wrecks of Lake Washington in high resolution -- and you can too! Kees will be telling us more about ongoing and completed documentation projects in Lake Washington as well as future efforts you can get involved with in this exciting presentation.


More information on GUE is available at the website:


Come join your fellow Seahorses for a great family-friendly meet up with some great friends, good food and cold beverages.


Non-hosted dinner at 6, Program at 7 PM.

Hoyo Negro Cenote - Dr Jim Chatters - Feb 28th Indoor Meeting - Special Event

Seahorses Indoor General Meeting
Thursday, February 28th, 2018
6:00PM – Dinner and Beverages!
7:00PM - Featured Program

Location: Rogue Brewhouse in Issaquah

Jim Chatters, Paleoanthropologist/Paleontologist, Hoyo Negro Project – A Mexican Cenote

We’re extremely excited to host Jim Chatters, Ph. D, a world renowned Paleoscientist. Jim has participated in archeological studies around in a diversity of locales for over 50 years. Jim is currently the principal investigator of the Hoyo Negro Project, located in an underwater cave in Mexico’s Yucatan Peninsula. For myself, as a Boeing engineer in the technology field, I think this project is particularly interesting. The primary reason is that they have assembled an extremely detailed digital 3D model of the underwater Cenote that may be explored, above water, in virtual reality.

The cenotes and underwater cave systems of the Yucatan Peninsula are emerging as one of the most promising frontiers for Paleoamerican studies. Following the end of the last glacial maximum, rising sea levels flooded the region’s maze of underground passageways and preserved a diverse Late Pleistocene fossil assemblage. A female human skeleton, named "Naia," found in spatial association with the remains of now-extinct fauna in the submerged subterranean pit of Hoyo Negro presents a unique opportunity for interdisciplinary Paleoamerican and paleoenvironmental research in Quintana Roo, Mexico. At 13,000-12,000 years BP, the young woman’s skeleton represents the oldest nearly complete individual yet found in the Americas.

More information on Jim and his fellow scientist’s incredible work on Hoyo Negro can be found on this fantastic, easy to navigate, website:

Premiering last year on PBS broadcast television station KCTS 9, but being re-broadcast this month, will be an episode of NOVA. This episode, entitled “First Face of America” will be covering the highlights of Jim’s work. Catch the broadcast or watch the episode here:

Report of the annual UWPCC 2018

posted Nov 7, 2018, 10:28 AM by Editor SeaHorse

This year was exceptional for weather conditions during the event. Calm water and sky’s prevailed along with a light fog.
We would like to thank our sponsors: Sea Soft Scuba for providing samples of a few of their many great products. 
Our participants cashed in on zipper wax, defogger for masks, soap for washing dry/wet suits. 
Air cards provided by Evergreen Dive Service, Underwater Sports, Light House Dive, TLSea.

Marker Buoy dive club was represented by participants: Dominic, Joan, Kosta, Ashley and Jasmine.
A crowd gathered for the competition to cheer on the contestants. This was the year for newbies. Yes my friends, half of the contestants had never carved a pumpkin underwater. 
As expected some of them were better prepared than others and knew that pumpkins floated.

Dom did very well for his first UWPCC by getting the pumpkin underwater. His entry was a bat for which he was rewarded with Best off as pumpkin pie.
Joan swept the competition away with “Most Artistic” category using her entry Catfish.
Team Ashley and Jasmine took their time getting into the water and the swim out. This may have been Jasmine’s first time diving in Puget Sound. 
Their entry Whale Shark won the category of “Best use of Sea life”.

Kosta brought a medium sized pumpkin that kept him afloat. Pumpkin 1, Kosta 0. My expectations are that Kosta will have a harness and 20 pounds of weight for next year’s entry.
Kosta gave up after 10 minutes of struggling with the buoyant orange gourd.

Seahorse Dive club was represented by SHDC President Tom Kingsbury, aka self-titled “Galactic Overlord”. Tom and Gary Schnaith teamed up to carve “Vampire Pumpkin”. 
The crowd voted and they received “Biggest Pumpkin”. This was Tom’s first time at carving a pumpkin underwater. 
Brad Redmond brought back three small gourds and named his entry “School of Pumpkin fish”. Brad took “Cutest” hands down.
Long time participants: Randy Pedersen and Ed Gullekson, carved “Millennial Orca”. The crowd cheered loudly and they received prizes for “Scariest” pumpkin.

Shore support personal for the event: Andrea Naert and Dave Ballard of the Marker Buoy and Brian Heath SHDC.

Side notes
Yes, there were several people in just swimsuits swimming by. It isn’t a “Polar Bear” dip for these folks. Many of them swim in the water several times a month. 
Visibility was 25 feet.
Tide was in and about 4 steps up from the beach. This made the swim out much shorter.

Results of the Photo and Video Contest

posted Nov 7, 2018, 10:25 AM by Ed Gullekson   [ updated Nov 7, 2018, 10:29 AM by Editor SeaHorse ]

Watch for announcement of 2019 calendars with contest winner photos, PacNW photos and Tropical photos.

Here are the results of the 2018 Photo & Video contest which was held on October 25th. Below are listed the categories with the winners name and their description of the winning photo or video:

Video - Randy Pedersen: My video, "Can You See Me?" is about how our local sea life can hide in plain sight. Except for the opening scene (Waves crashing on a Hawaiian beach) it was shot exclusively in Puget Sound and the San Juan islands.

Above Water Dive Related - Chris McKenna: "Waiting for Mantas". Taken 5/23/18 at 6:49 PM. We were going to dive with the Manta Ray's at night (I highly recommend this dive) and while we were moored and waiting I saw a beautiful sunset setting up. So I grabbed by camera, fins, and mask and dove in. I had to swim away from the boat a bit to make sure I could get the boat in frame along with the sun.

Cold Water Macro - Ed Gullekson: Multicolored dendrontid nudibranch - taken at Shaw Island in the San Juan Islands September 21, on a REEF Advanced Assessment Team survey. It was taken on the last day of the trip. These are common nudibranchs in the San Juan Islands.

Cold Water Wide Angle - Ken Engelmeyer: “Strange Bed Fellows” or “The Odd Couple” Cabazon on eggs with Lingcod sharing same rock pile. Photo taken at the Edmonds UWP December 10, 2017

Warm Water Macro - Ed Gullekson: Neon goby on coral - taken at Key Largo, FL, in June on a REEF Survey on the first dive of the trip. These are a common species and a few of them would let me get close enough to shoot macro photos.

Warm Water Wide Angle - Randy Pedersen: My photo, a lion fish from Tiger beach in the Bahamas was shot on the February 2013 trip there. It was shot in about 20fsw on a sandy bottom next to a very large stud link anchor chain that has been there for a very long time.

Novice - Chris McKenna: "Diver's at Hoovers Pinnacle" taken 5/19/18 at 9:19 AM. This was a reef dive and it was a photo in which I wanted to get a silhouette of a diver in that water. I was lucky to get 2 of them--one was a student and the other an instructor. It was a matter of turning around from my current position (after taking a photo of an eel or something).

Wolf Eels - Pieter Booth: "My photo of "scarface" the wolf eel was taken at Sund Rock last year on a club dive. It was on the North wall at about 50 fsw. Sund Rock is wolf eel rich and we usually see 6-12 individuals. This one has the most beat-up look of any I have seen in my many years of diving the PNW. Missing its left eye and hardly had any teeth.

Ken's photo of the “Strange Bed Fellows” (Cold Water Wide Angle) was chosen as the "Best in Show"

Thanks to all the winners for sending me the descriptions of their winning entries. My apologies for taking so long to make this post.

Thanks to the 23 members who voted after viewing all the pictures and videos entered in the contest. We will try to find a better venue for next year.
