First live video of a colossal squid highlights one of the most exciting knowledge gaps in deep ocean exploration

April 28, 2025April 28, 2025 Andrew Thaler

Earlier this month, the good folks at the Schmidt Institute for Oceanography, unveiled the first video footage of a colossal squid. Colossal squid were first described 100 years ago, but have never been seen live. What little information we have comes from specimens that washed up on beaches or from hard parts found in the … Read More “First live video of a colossal squid highlights one of the most exciting knowledge gaps in deep ocean exploration” »

More people care about marine biodiversity and saving the ocean than ever before. But progress towards evidence-based conservation is hindered by widespread public misunderstanding of the key issues in play. You’ve heard versions of this rant from me for 15 years, but this is not a post about sustainable fisheries, or shark conservation. This … Read More “The wrongest belief about the deep sea is wronger than you know” »

It is your ocean. You should have access to the tools to study it.

The structure of scientific inquiry has coalesced around a model that is, in general, both expensive and exclusive. This centralizes knowledge production within a circle of individuals, organizations, and institutions which rarely reflects the breadth of identities, experiences, and ways of knowing of those most directly connected to the places being explored. Nowhere is this … Read More “It is your ocean. You should have access to the tools to study it.” »

The world’s largest cold water coral reef lies beside the first experimental deep-sea mining test site

In a region once thought to be so ecologically uninteresting that it was viewed as a useful testbed for deep-sea mining equipment, NOAA researchers have detected what could be the world’s largest cold water coral reef. “For years we thought much of the Blake Plateau was sparsely inhabited, soft sediment, but after more than 10 … Read More “The world’s largest cold water coral reef lies beside the first experimental deep-sea mining test site” »

Deep Ocean Exploration needs to move beyond Imported Magic

January 16, 2024 Andrew Thaler

Exploration, Featured, Science

It shouldn’t surprise anyone that deep ocean exploration is an expensive endeavor. Vessels, instrumentation, deep-submergence vehicles, and analytical tools are costly to run and the specialized training needed to maintain that equipment is often a career in itself. Deep-sea research cruises are among the most logistically complex peacetime operations in human history. When access to … Read More “Deep Ocean Exploration needs to move beyond Imported Magic” »

Discovery of a Great Hammerhead Nursery

Conservation, Exploration, Uncategorized

Happy Shark Week (if you celebrate), and I’m so excited to share our newly published open access paper about our research on juvenile great hammerheads (Sphyrna mokarran) with you! (It’s been hard to keep this one to ourselves).

Great hammerheads are an iconic shark species which have undergone significant population declines globally. In 2019, they were assessed as Critically Endangered by the IUCN Red List, which reported overfishing as the greatest threat to their survival. Great hammerheads are known to make incredible long-range migrations and cross state and international boundaries, making them challenging to protect as adults. Little is known about where they are born or where they spend their early years of their life, although there have been scattered reports of juveniles from the Gulf of Mexico, the Florida Keys, and one report from Georgia.

Identifying habitats that are important to juvenile sharks matters because young sharks are often the most vulnerable individuals in a population, and their survival is vital to the future of their species. Many juvenile sharks spend time in “nursery areas”—places where they are less likely to be eaten by predators, or where food resources are abundant. They then expand their ranges as they age, covering more distance as they grow larger. Identifying nurseries has long been a conservation priority for managers and scientists. After several years of research, our team has collected the first scientific evidence of a nursery area for great hammerhead sharks on the Atlantic coast of the United States—within sight of the skyline of Miami, Florida.

There’s a three-part established test for an area to be identified as a shark nursery: 1) Juvenile sharks are more commonly encountered in that habitat than elsewhere; 2) they remain in the area for extended periods; and 3) The area is used repeatedly over years. Our results demonstrate that this area definitely meets two of these criteria, with preliminary evidence that it also meets the third. We’ve found the same habitat may be a nursery area for several other shark species too, including scalloped hammerheads, another Critically Endangered species!

New dives to Challenger Deep raise old questions about privatization and exploration

For over 50 years, deep-ocean explorers have been able to claim that more people have walked on the moon than have dived to the deepest point on the Earth. Only two men descended into Challenger Deep in the 20th century–Don Walsh and Jacques Piccard–they were joined in the early 2010s by director James Cameron. Earlier this year, Victor Vescovo became the fourth to reach the bottom of Challenger Deep and, over the course of several subsequent dives this summer, the ranks of those who’ve reached the deepest ocean has swelled.

Astronaut, oceanographer, and former NOAA Administrator Kathy Sullivan and explorer and mountaineer Vanessa O’Brien became the first and second woman to dive to the bottom of Challenge Deep aboard the privately owned HOV Limiting Factor, piloted by Vescovo and his team.

Emerging technologies for exploration and independent monitoring of seafloor extraction in Areas Beyond National Jurisdiction

[The following is a transcript from a talk I gave at the 2019 Minerals, Materials, and Society Symposium at the University of Delaware in August, 2019. It has been lightly edited for clarity.]

Good afternoon and thank you all for coming. I want to change tracks for a bit and scan the horizon to think about what the future of exploration and monitoring in the high seas might look like because ocean and conservation technology is in the midst of an evolutionary shift in who has access to the tools necessary to observe the deep ocean.

This is the Area. Areas Beyond National Jurisdiction, International Waters, the High Seas, the Outlaw Ocean. It’s the portion of the ocean that falls outside of national EEZs and is held in trust by the UN under the Convention on the Law of the Sea as the Common Heritage of Humankind. It covers 64% of the ocean and nearly half of the total surface of the Earth. It’s also the region in which most major deep-sea mining ventures intend to operate.

The Aquarius Project: The First Student-Driven Underwater Meteorite Hunt

Pirates! Robots! Meteors! A team of plucky teenage explorers! If this doesn’t end up as a feature film, I’ll eat my red watch cap.

On Monday, February 6, 2017 a meteorite dropped out of space and dropped right into Lake Michigan. Since then, a team of young explorers sponsored by the Shedd Aquarium and the Adler Planetarium have been combing the lake for the lost meteorite. Catch up with this epic adventure through their podcast and on OpenExplorer. The search continues into 2019.

Iceland’s Shallow Hydrothermal Vents

Not all hydrothermal vents emerge in the deep sea. Of the coast of Iceland, shallow water vent spew forth their hydrothermal plumes in the shallows, where small underwater robots can easy access. You’d think we’d know more about them than their deep ocean counterparts but we actually know less.

Iceland’s Shallow Hydrothermal Vents hopes to fill in some of our understanding of these weird and wonderful ecosystems.

Search for Slave Shipwrecks

On a hot summer day in the murky waters of the man-made Millbrook Quarry in Northern Virginia, a group of about 25 people outfitted in scuba gear take turns going down to a depth of 30 feet, testing their compass reading skills, flooding their masks and practicing emergency ascents without air. The sight is not so unusual since Millbrook is the main training and certification site for scuba divers in the DC/Maryland/Virginia area and often hosts such groups. What might give folks pause, however, is that upon closer look they may notice that all 25 of the divers are African American. And if they chat with this unexpected bunch, they might also find that a majority are certified and qualified to search for, document and help excavate slave trade shipwrecks.

Divers with Purpose and the Slave Wrecks Project will be traveling across Africa and the Caribbean documenting the stories of underwater archaeologists working to preserve the history of the Atlantic slave trade buried at sea.
