Over 15 years of ocean science and conservation online
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” »

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” »

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?” »
Everyone knows that sandbar shark is #BestShark.

I have a problem with the OpenCTD. The OpenCTD is a low-cost, open-source oceanographic instrument that lets you take fundamental water quality measurements for a fraction the cost of commercial alternatives without sacrificing data quality. It’s rated to 140 meters, and we’ve tested that, once, in a bathymetric chamber, and then, occasionally, in the field. … Read More “I built a DIY hardware store pressure vessel to test ocean science tools from the comfort of my shed.” »
