Over 15 years of ocean science and conservation online
The leading textbook in Marine Conservation Biology (Norse and Crowder) is 20 years old. It’s great and it shaped the field for a generation, but a lot has happened since it came out. There are new conservation threats, new policy tools, and new research methods to study them. And in that time, we’ve radically changed … Read More “We’re making a new marine conservation science and policy textbook. What do you want to be in it?” »
One day, 5 to 20 million years ago, a tongue-eating isopod parasitized some unknown Miocene fish, embedding itself in the fish’s mouth where wit would grow and consume scraps as its host feed. That partnership lasted until the fish, itself, became food, likely eaten by an ancestral sea turtle. And that’s where a million-year old … Read More “A tongue-eating isopod takes a 5-million+ year journey through fossilized feces” »
Anupa Asokan, founder and executive director of Fish On—a new fishing interest organization working to advance ocean conservation policy—recently published a peer-reviewed perspective in Frontiers, “Marine Protected Areas as a Tool for Environmental Justice.” Anupa is a lifelong fisherwoman and has become a passionate advocate for ocean conservation and justice. I’ve known her for several … Read More “People and Ideas You Should Know: 5 Questions with Anupa Asokan” »
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” »
As an informal learning assignment, I have my students use social media to follow ocean science and conservation experts for the semester. Each week, they’re asked to check social media for a few minutes, and report on something interesting they learned about marine science or conservation (and why they thought it was interesting.) I’m sharing … Read More “My “Follow ocean science and conservation experts on Bluesky and Instagram” assignment” »
Giant deep-sea tube worms. When the RV Knorr arrived above Galapagos Rift in 1977, a team of geologists, geochemists, and geophysicist, including Robert Ballard who would go on to locate the wreck of the Titanic among other ocean-shaping discoveries) was prepared to witness something never before seen: a geyser of superheated, chemical rich water erupting … Read More “Giant tube worms dwell in the deep places beneath the ocean floor.” »
Last June, a striking image of a pride flag made up of NASA imagery became the most-liked post on the new social media network Bluesky, a post it held for 2 months. I spoke with its creator Rachel Lense about how it was made, and what it’s reception means for inclusion in science. This image … Read More “The story of the pride flag made from NASA imagery: Bluesky’s most-liked image” »
On Thursday, September 26th, I spoke on a “Biodiversity Leaders for Harris-Walz” zoom call. This is the text of my remarks, including links to learn more. Good evening. I’m Dr. David Shiffman, an ocean conservation scientist who studies threats to marine life and how we can solve those problems using wise evidence-based policymaking, through equitable … Read More “My remarks for Biodiversity Leaders for Harris Walz” »
One of the most iconic images of shark behavior is a great white shark hitting its prey so hard from below that the whole shark flies out of the water. This behavior, called “breaching,” has been documented in many species, and is useful for a variety of ecological functions, not just hunting. I spoke to … Read More “Jumping the shark: New study reviews the breaching behavior of sharks and rays” »
Over 15 years ago, I set sail from Matupi Harbor, Papua New Guinea to a spot in the middle of the Bismarck Sea between New Britain and New Ireland to study and understand the ecological diversity of a hydrothermal vent system resting beneath a submerged volcano 1600 meters beneath the sea. That hydrothermal vent system … Read More “What is going on at Solwara I?” »
