The Maritime Museum of San Diego recently acquired DeepFlight I, a unique “flying” underwater submersible developed in the late 1990s. You can read more about this amazing, advanced submersible here.
Visitors to the San Diego museum might be astonished to learn that this one-of-a-kind prototype appears in every episode of Star Trek: Enterprise!
DeepFlight I can be seen momentarily in the Star Trek: Enterprise introductory sequence, which begins every episode. The sequence depicts the evolution of human technology and exploration. DeepFlight I appears at the 34 second mark here!
Super cool!

This coming Saturday, November 15, 2025, between noon and 3 pm, the public is invited to step aboard Norwegian tall ship Statsraad Lehmkuhl, which is currently visiting San Diego.
The large, beautiful 1914 ship with an intriguing history is docked downtown at the Broadway Pier. It arrived yesterday and will be staying in San Diego through Sunday.
Why is the three-masted barque, based in Bergen, Norway, tied up to Broadway Pier? The Statsraad Lehmkuhl is on a 12-month global voyage as ambassador for the UN Ocean Decade. Its One Ocean Expedition includes sail training, ocean science, education and diplomacy to inspire action for a sustainable ocean.
From San Diego it will sail down to Mexico, then Central and South America. According to a banner that I photographed, the Statsraad Lehmkuhl will visit a total of 26 ports on 3 continents, and travel 30,000 nautical miles!
Yesterday I took some photos from the pier to provide an idea of the tall ship’s immense size and beauty. If you’re downtown on Saturday, you might want to step aboard. It’s your possibly once-in-a-lifetime opportunity!

A special event is coming up next Saturday, November 15, 2025. Visitors to the Maritime Museum of San Diego will have the opportunity to explore how emerging technologies are transforming how we use and protect ocean resources.
The event is free with General Admission and is perfect for families, students and anyone interesting in learning about blue technology. Hours are 10 am to 4 pm.
What is Blue Tech? It’s a category of advanced technologies focused on the sustainable development of the world’s oceans and coasts, also known as the Blue Economy.
According to one sign in the Maritime Museum, there will be hands-on exploration and interactive experiences concerning underwater robots, engineering, data tools and more. Student marine clubs will be there with their own innovations, too!
Super cool!
Some high tech equipment I spotted today near the sign…

Have you seen the enormous sailboat Persévérance docked in San Diego?
I saw the amazing boat this morning. It was a little north of the Maritime Museum of San Diego. I was told it has been in San Diego the past few days.
The Persévérance is a research vessel operated by world-renowned French explorer and polar expedition pioneer Jean-Louis Étienne.
According to a map displayed on the boat, the 2025-2026 Jean-Louis Étienne and Elsa Pény-Étienne’s Expedition has has already visited Greenland and the Arctic region via the Northwest Passage. After leaving the West Coast it will cross the Pacific Ocean and head south to study Antarctica!
The unique oceanographic schooner gathers data on climate and ocean currents, visits Marine Protected Areas, and seeks to analyze human impact on the oceans. Marine Protected Areas on the itinerary include Clipperton, French Polynesia, Ross Sea, and the proposed Dumon d’Urville MPA in East Antarctica.
I asked whether there will be public tours of this remarkable sailboat, but was told, unfortunately, no.
Check out what arrived at the Maritime Museum of San Diego yesterday! This super cool “Deep Flight” submersible!
This electric, one-man submersible was developed about 15 years ago by Hawkes Ocean Technologies. It’s now on display in the museum’s steam ferry Berkeley, in a spot where many model ships can be viewed.
I’m reasonably sure this is DeepFlight I, a submersible that served as a technology testbed for DeepFlight II. You can see a photo and learn more about Hawkes Ocean Technologies on this website.
The exhibit is so brand new, the submersible is still on rollers and there’s no information sign in the museum yet. (I was told that to roll the submersible into the Berkeley, part of the museum’s front desk had to be removed!)
While I don’t know too much right now, I’ll endeavor to learn more tomorrow when the Maritime Museum of San Diego has a special member event. I’ll provide more info here in an update.
But look at how cool this thing is! Imagine lying prone, squeezed inside the narrow craft, down in the mysterious depths of the sea, flying along silently like an underwater aircraft, water and sea life all around!
UPDATE!
A few days later, I noticed two of the historic submersible’s wings had been reinstalled.
A sign also points visitors to a cool YouTube video concerning the DeepFlight I. Watch it here.
UPDATE!
A sign appeared later. I was surprised to learn DeepFlight I briefly appears in the introductory film sequence of Star Trek: Enterprise!
Eight years ago I posted the blog Natural beauty at the West Coast Shell Show. Today, while walking through Balboa Park, I noticed the West Coast Shell Show was being held again in the Casa del Prado, so I checked it out!
Yes, there were hundreds of amazing shells. All types! I’m no expert when it comes to seashells or marine organisms–all I know is that these jewels from the ocean can be indescribably beautiful. I can see why people collect them.
Dealers had tables full of specimens and there were educational displays to read, too. I learned these shells were gathered from all around the world. One gentleman told me that collecting shells at protected San Diego beaches is illegal.
I must admit that while walking along the sand I’ve never seen anything that approaches these perfect specimens at the Shell Show. When lucky, I might observe very tiny polished shells underfoot, or an occasional sand dollar, or a broken abalone piece glinting in the sun.
Searching for what the vast ocean has churned up is instinctive, I suppose. The sudden discoveries–even shells that are broken–invite a closer look. They’re small hints of our planet’s immense magnificence.
Western Flyer, the world’s most famous fishing boat, will be visiting San Diego on March 26, 2025, and you have the opportunity to tour it!
If you’ve read John Steinbeck‘s famous book Sea of Cortez, you’ll recognize the name of this fishing boat. In 1940, Steinbeck and his friend Ed Ricketts explored the Gulf of California in this very boat.
For decades the boat was lost, then it was found and restored by the Western Flyer Foundation. It now operates as a floating classroom, educating youth about the intersection of science and literature.
With a General Admission ticket, visitors to the Maritime Museum of San Diego will be able to step aboard and tour the legendary fishing boat as it makes its visit to our city!

This very colorful new mural was painted a couple months ago on the north side of the Oceanside Transit Center parking structure. It celebrates Oceanside–its Spanish mission and fishing history, and the nearby Pacific Ocean!
Jonny Pucci created the striking mural. See his Instagram page here.
According to this article, the work is part of MainStreet Oceanside’s Art that Excites program, which aims to install up to 10 murals in public spaces throughout downtown Oceanside.
I love how so many Southern California cities and communities continue to enliven neighborhoods and destinations with public art. No matter where I walk, I always seem to encounter something new. That was certainly the case yesterday!
Next time I walk in Oceanside, I have no doubt I’ll stumble upon more cool sights like this. Meanwhile, stay tuned for more outdoor art that I also discovered yesterday–in Escondido!
Enjoy a few more photos of the Oceanside Transit Center parking garage mural…

Can seaweed be beautiful? It definitely is in an exhibit now on display on the first floor of San Diego’s Central Library!
The Curious World of Seaweed explores the science and historical importance of seaweeds, algae and kelp, and does so using fantastic images, such as the ones you see in my photographs.
Indigenous peoples have utilized seaweed for thousands of years. Taking various parts of certain seaweeds, they would create fishing lines, containers for water and funnels for fish traps. Edible seaweeds were commonly used for food–as they are today! Sushi anybody?
In modern times, the thousands of species of algae and seaweeds have been studied and more completely understood. These living organisms sustain ocean biodiversity and are an important part of our planet’s ecology.
The extensive exhibit is based on the research, photography and writings of Josie Iselin. Her latest book is also titled The Curious World of Seaweed.
As explained here, Iselin’s writing and art focusing on seaweed, kelp and sea otter puts her on the forefront of ocean activism, presenting and working with scientists and environmental groups working to preserve the kelp forests of our Pacific Coast.
There’s much to learn when viewing this exhibit, but what struck me most was the exquisite beauty and complexity of the different colored seaweeds. You’ll enjoy viewing the illustrations, photographs and works of art.

Those who are fascinated by tall ships, exploration and the evolution of technology don’t want to miss a great new exhibit at the Maritime Museum of San Diego. It’s titled the Art of Navigation.
Visitors to the exhibit learn how navigators have used maps, charts and a variety of tools to find their way across the oceans and through dangerous waters. The extensive displays include some exceptionally rare antiques. Old instruments that can be viewed include an astrolabe, backstaff, nocturnal, traverse board, chip log and reel, hand-held telescope, cross-staff, quadrant, taffrail log, navigation slate and more! These instruments might seem primitive when compared with modern technology, but ship’s captains successfully sailed around the planet with the information they provided.
Personally, I like to read nautical stories set during the Age of Sail. As I read I’ll come across the names of these instruments, and at times puzzle over their application. The descriptive Art of Navigation exhibit brings helps to bring those adventurous old stories to life!
The exhibit also includes beautiful paintings and model ships, and even a display directly related to the Maritime Museum’s famous Star of India!
The Art of Navigation is free with museum admission. As advertised, it does indeed turn intellect, math, nature and science into beauty!
