The Roy Miner Collection was donated to Miami Science Museum in 1976 and sat untouched in the archives room until it was re-discovered again in 2000 by Rachel Delovio who was the Collections Manager at the time. The archive itself consists of 4500 glass lanternslides and negatives made between the 1920s to the 1940s as well as various ephemera from the period. The story of how it was found again is dear to our hearts, because the practice of carefully combing through and looking for unknown clues at the Miami Science Museum is what The Curious Vault column is based on. In exploring the Miner Collection our team had a unique “EUREKA” moment when we came across a peculiar series of watercolors depicting various underwater scenes and specimens.

On the sketches themselves, 6 in total, are various notations written in pencil, but one consistency screamed out for further investigation. They are numbered, “Tube Sketch No. 3” for instance. We decided to spread them out to check the notations on the pictures and saw that some are simply numbered, while others have longer descriptions. Two in particular say “Sketched from Mr. Williamson’s Submarine Tube”. It was then that we realized that these watercolors were actually made underwater (!) at Hog Key Inlet in the Bahamas in 1924.

Diving a little deeper we found an image of the apparatus at work. Captain Charles Williamson initially built the device around the turn of the 20^th century for the purposes of treasure salvage. A 1911 article in the New York Times shows the excitement around the search for $500,000 in silver from the shipwreck Merida off the shores of Williamson’s hometown Norfolk Virginia. However, by the 1920s, the treasure of the Merida was still unrecovered, and it seems Williamson’s sons had begun to understand the Tube’s power as a facilitator to the study of underwater life. They decided that the Tube was perfectly suited for documenting underwater life, particularly through photography, and most importantly motion pictures (see January 1915 article in The American Magazine).

The Tube took many different technical variations, but it’s most public and important contribution to underwater exploration was the production of the groundbreaking cinematic photography used in the 1916 version of 20,000 Leagues Under the Sea. Skip to 30:00 into the YouTube clip for underwater footage, or more interestingly 59:10 for the footage of the sea monster that the Williamson Brothers patented a year after their production company made the film. The movie was the first time the general public had ever been exposed to underwater motion picture footage. Think of what it must have been like at the time to see this unbelievable motion picture. This is a fascinating link to film history that the Miami Science Museum can make to real objects in their collection.

The watercolor sketches are currently on display at the museum for public viewing. They were made by Charles E. Olsen, whose biographical information is scarce. He appears to be a highly skilled amateur, and the watercolors themselves are beautiful in their near perfection. Most importantly is their uniqueness to the time period. These paintings were made underwater in 1924! It appears, as these pictures show, that the Williamson brothers went on to utilize the Submarine Tube for not only entertainment, but also scientific discovery. Their contribution to the niche world of early underwater photography and exploration is significant. This series of watercolors is just one of the many treasures to be uncovered inside The Curious Vault. Endless fascination lay hidden and ready for all of our eyes to see. We are so glad to be a part of this cultural excavation and hope that you will stay with our continued journey of the Museum’s hidden secrets in the New Year.

A living fossil, sea turtles still nest up and down the busy and overbuilt South Florida coast and travel past our shores throughout the year. The various species of ocean roaming turtle are approximately 200-300 million years old but because they lay their eggs on our beaches, scientists are able to closely study the nomadic animals. For this reason, and with modern techniques such as satellite tagging, we can occasionally glimpse closely into their mysterious lives.

One of the finer specimens in the Miami Science Museum collection is a gigantic loggerhead shell. It is from a specimen estimated to be around 150 years old when it died! The shell is marked with a label that the object came from United States Customs, confiscated from someone trying to trade illegally in sea turtle paraphernalia. This is part of the reason the Museum’s collection of sea turtles, around 25 specimens, is so impressive. Even though bycatch – the accidental killing by commercial fisherman – is the greatest threat sea turtles, for many years they were hunted for their shells as luxury items, or to adorn jewelry. In some places, like in Cuba, the flippers, eggs, and head of sea turtles are still eaten by people holding on to age-old traditions, even though hunting them was banned years ago.

The Miami Science Museum’s very own Fernando Bretos is an expert on green turtles and he follows their movements and mating throughout the Caribbean, but mostly focusing on nesting and migrations between Florida and Cuba. Fernando is a Cuban-American who is trying to pick up the dialogue between Cuba and the United States through sea turtles. It is one of the few links in which exchange is allowed and encouraged, “maybe the only link even,” states Bretos, “and we must share information and resources to protect the animals.” Sea turtles become not just amazing animals to study and appreciate but are also fascinating to consider as a bridge between two politically embattled nations.

Fernando is attracted to sea turtles, not only because they are beautiful and need help, but also because he sees a link to himself. They are migratory; he has lived in Cuba, the U.S.A, and Australia. And the green turtle traveling through the Gulf Stream is particular to both his homeland of Cuba and home country of America. But he feels it’s important to understand what our changing definition of nature is. Fisheries biologist Jeremy Jackson suggests at the time of Columbus the green sea turtle population was approximately 660 million turtles. The Tortugas were named such because of this drastic overabundance, and some tales speak of sailors walking from shell to shell on over crowded beached. Indeed sea turtle was one of the primary food resource in the Caribbean. That is in contrast with the estimated 88,000 nesting females in existence today, as reported by the Sea Turtle Conservancy.

In a bittersweet moment, it is almost because of this overabundance of sea turtles in combination with the regulations now put against their trade, that the impressive collection of sea turtle specimens at the Miami Science Museum could be compiled. Through conservation and conversation they can come back, but the dialogue must remain. The collection also shows us how important sea turtles are locally in Miami. In fact, Florida’s beaches are the most important nesting site for loggerhead turtles on the planet! Even though it is 25 specimens, because the scientific community is trying to conserve the animals, a collection like the one the Miami Science Museum is actually quite impressive. It would be impossible to compile today, making it truly unique.

Turtle tracking via satellite

The image above is a satellite track from SeaTurtle.org of five green turtles that were tagged off the coast of Guanahacabibes UNESCO Biosphere Reserve in August 2012 immediately after laying eggs. Since their tagging, these five female turtles have begun their annual voyage to foraging and mating grounds. Two of the animals, one named Conchita, after Fernando’s mother, made a fast dash immediately for Florida. Conchita, whose track is labeled in green, suddenly made an abrupt turn and swam to Mexico’s Yucatan peninsula where she is now feeding on shallow sea grass beds.

It is critical to study the migratory movements of these enigmatic creatures. Without knowing where they feed, nest or travel, it is impossible to draft policies to protect them, particularly across international maritime borders.)

Calcite

Tucked away on a high shelf in the collections room of the Museum of Science is a startlingly unique rock specimen. It is white with long jutting crystal arms and made of a fragile mineral called calcite. The piece looks like it comes from completely different planet.

How calcite looks isn’t the only amazing thing about it.  Scientists in England have recently shown that calcite might unlock the secret to invisibility. They even make a paperclip disappear! By using the light that reflects off two specially made pieces of calcite, they are able to make the object behind them undetectable. Harry Potter’s invisibility cloak could one day happen due to this amazing mineral.

Calcite Detail

If you want to learn more about calcite, the Miami Mineralogical and Lapidary Guild is the best resource in town. They are a quirky and fun group, dedicated to all things rock-related. Founded in 1955, the Guild has been an affiliate study group with the Museum for those interested in rare or semi-precious stones, cutting and shaping them, and most importantly learning about them.  They are very friendly, and welcome all visitors to learn about their unique hobby.

The members of the Guild explained to me that you can identify the specimen as a calcite because of its “habits”.  Simply put a habit is the rock’s shape, or in this case, the crystal arms that jut out. How the habits are formed depend on where the rock was made. This particular specimen was found in Wisconsin and its habits come from the precipitation of either ground water or surface water piling on top of each other and hardening over the course of millions of years. The water drips and dries leaving coatings with small particles of the limestone walls that build up and form the calcite.

One of the more fascinating places calcite can be found is the Snowy River Cave in New Mexico. There is a dry underground riverbed of white calcite, much like the Museum specimen. Only 9 miles of the cave has been mapped and the full extent of the bed is still unknown, but the discovery is one of the most important recent calcite and caving finds in America.

“Nature makes it different every time,“ said the Mineralogical and Lapidary Guild’s Vice President K.C. Foster.  This is an important sentiment for minerals because, like a fingerprint, no calcite is ever the same. Whether an underground riverbed, a composite that can make things invisible, or a beautiful specimen like the one in the Museum’s collection, calcite is an amazing and unique mineral.
