Santa Barbara divers helped innovate deepwater diving technology

How specialized oxygen mixtures like heliox enable deep diving without feeling drunk

Beyond a depth of about 30 meters (98 feet), if divers are breathing surface air, which is about 78% nitrogen, underwater pressure forces more nitrogen into the bloodstream and induces nitrogen narcosis, whose symptoms resemble alcohol intoxication. Through saturation diving, where nitrogen is replaced with helium—an inert gas—deep divers can maintain cognitive function while working for extended periods.

The 1969 Santa Barbara oil spill galvanized the modern environmental movement

In January 1969, an oil platform off the coast of Santa Barbara ruptured, releasing roughly 3 million gallons of crude into the Pacific. The spill killed over 10,000 seabirds, dolphins, and seals, coating 35 miles of coastline.

Diving boards disappeared out of safety, but they don't cause most diving accidents

Bouncy diving boards were widely adopted in backyard and community pools in the 1960s. Reports identifying diving as the primary cause of sports-related spinal accidents exaggerated the role diving boards played (most diving injuries were in lakes, beaches, and rivers) and gave insurers a basis to reduce coverage.

The history of deep-sea mining and its governance by the International Seabed Authority

The British HMS Challenger research vessel identified metal-rich seafloor rocks between Hawaii and Mexico in the 1870s, but rules governing which nations control which parts of the ocean were not established until 1958 by the UN. It later established the ISA to oversee mineral-related operations in international waters.

Santa Barbara's Channel Islands revealed the oldest skeletal remains in North America

IN 1959, archaeologists found a human femur jutting out from a rock face on Santa Rosa Island. Using the then-new technology of radiocarbon dating, they measured the age of the remains at 13,000 years—the oldest in the continent.

In this podcast episode, business-minded experts discuss the opportunities founders see in the ocean, including seagrass restoration, underwater cable networks, and more.

The invention of the barometer proved that air has weight

The instrument measures air pressure by creating a partial vacuum—a region with very low density—which serves as the basis for how suction works. Mercury-based barometers were used until 2007, when they were restricted due to mercury's toxicity.

Britain’s bottle innovation saved Champagne

Champagne wouldn’t be where it is today without a surprising partner: 17th-century British glassmakers. An energy crisis caused by deforestation—not enough trees to burn—led to the search for an alternative fuel source. Enter coal. The plentiful resource burned much hotter than wood, creating stronger glass that could stand up to the pressure of the carbon monoxide produced by the wine’s second fermentation and solving one of the fledgling industry’s most vexing problems.

The Indigenous people of the central Californian coast made advancements in basketry, small stone tools, the use of shell beads as currency, and plank canoes for seafaring. In the years before European contact, their numbers reach 25,000 across 150 settlements.

Why helium helped preserve the US' founding documents, but was later replaced

In 1951, the Charters of Freedom were stored in glass and metal cases filled with helium, which would not chemically react with the documents. After microscopic cracks were identified in the glass through which helium could leak out of and—experts feared—pollutants could infiltrate, new encasements made of aluminum, titanium, and argon replaced the old system in 2003.

The evolution of spacesuit design

Spacesuits have come a long way since cosmonaut Yuri Gagarin's orange jumpsuit used in the world's first entry into space in 1960. The iconic outfit is a crucial feature of all space exploration, ensuring humans are protected during launch, spacewalks, re-entry, and more. From innovations in thermal wear to the incremental changes to space helmets, dive into spacesuit history here.

How microbes limited the damage and helped clean up the Deepwater Horizon oil spill

A bloom estimated to contain about 100 sextillion microbial cells broke down much of the 4.1 million barrels of spilled crude oil into nontoxic compounds in what was one of the most significant bioremediations of a human-made disaster. The microbes involved acted similarly to the first patented genetically modified organism in US history: an oil-eating bacterium engineered in 1971.

Santa Barbara's streets are slightly off-kilter because surveyors used rawhide—which contracts and shrinks with temperature fluctations—to plan them.

The ocean's ability to store carbon long-term is being hindered by marine heatwaves

More than 4,000 robotic floats with biogeochemical data sensors, including oxygen, pH, nitrate, suspended particles, chlorophyll, temperature, and conductivity, have been deployed as part of the Global Ocean Biogeochemical Array. They have identified changes to ecosystem structure affecting the ocean's ability to transport carbon from surface waters into the deep.
