Saving the Blue Bloods: Horseshoe Crab Edition

We use horseshoe crab blood to test every FDA approved drug given to humans. Yet with horseshoe crab populations dropping and a feasible replacement test already developed, why haven’t we made the switch? Kristin HuizengaI am a masters student studying Biological Oceanography at the University of Rhode Island Graduate School of Oceanography. My interests are in […]

A boon to ocean conservation? Certain fungi can degrade marine plastics

Brunner I, Fischer M, Ru ̈thi J, Stierli B, Frey B (2018) Ability of fungi isolated from plastic debris floating in the shoreline of a lake to degrade plastics. PLoS ONE 13(8): e0202047. About a year ago, I decided to make a move towards reducing my plastic consumption. Working in environmental conservation leaves you with […]

Swimming with the fishes

Studying organisms in their natural habitat is tricky business (and not in the GoodFellas sense). A recent paper from MIT announces the arrival of SoFi, a bio-inspired robot that swims like the fish it is designed to study. And it is run with a Wii controller…underwater video games have arrived! Eric OrensteinEric is a PhD […]

That idea doesn’t suck: Hitchiking fish inspires a robotic suction disk

How do scientists build better suction cups? Turn to nature’s hitchikers for inspiration! Read on to see how remoras inspired a robotic suction disc that does a great job of sucking! Ashley MarranzinoI received my Master’s degree from the University of Rhode Island where I studied the sensory biology of deep-sea fishes. I am now […]

Using seabirds to study squid

How do scientists track fast swimming squid in the remote and vast open waters of the Southern Ocean? Probably not in any way you’d expect. They use squid predators, specifically a seabird—the wandering albatross—to find the squid for them. These albatrosses are outfitted with some very cool technology to bring the researchers information on their […]

OceanTech: profiling the sub-surface via Argo floats

The final post of theme week introduces the Argo array, an international effort to understand the ocean’s sub-surface via technological floats that enable continuous, real-time temperature and salinity data collection. Data collected from the Argo array can be coupled with satellite and shipboard measurements to provide a more complete understanding of global ocean dynamics. Anne […]

TBT Old School Ocean Tech: Simple Sampling Gear

Sometimes it’s the simple things in life that make it all worth it! Well, it may just be me, but I love using the tried and true old school sampling gear, despite all the complex gadgets and gizmos that seem to be developed faster than I can learn about them. In today’s ocean tech post, […]

Studying plankton from an atmospheric satellite

Scientists found a way to repurpose data from an atmospheric satellite to study the tiny creatures at the base of most ocean food webs. The instrument, originally designed to study aerosols, allowed researchers to build the most complete record of polar plankton activity ever assembled. Eric OrensteinEric is a PhD student at the Scripps Institution […]

Sub sea ice technology aims to expand Arctic plankton surveys

A German research team tested out three devices for studying plankton in Arctic sea ice. These new methods might allow scientists to expand Arctic primary production studies and yield new insight into these important, understudied ecosystems. Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His research in the Jaffe Laboratory for […]

Technology for Turtles: TurtleWatch Program to Protect Sea Turtles and Assist Fishermen

A technology that both benefits fishermen and helps prevent sea turtle bycatch? Yes, please! The great news is that it exists! And now, it has been updated to include leatherbacks. Read on to learn more about TurtleWatch. Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island […]

Need help counting bubbles? Now you can use sound!

Bubbles elicit scenes of childhood summers playing on the front stoop or backyard. On the other hand, put bubbles at the bottom of the ocean and you will find highly educated adults toiling with complicated mathematical equations and state-of-the-art technology. Sarah FullerWith academic backgrounds in oceanography, geology, and environmental education, Sarah has traveled to far […]

The problem with data sets: Cuvier’s beaked whales vs. Navy acoustic testing

Congratulations on the longest and deepest dive EVER! Please, ignore the regular acoustic testing…. The elusive Curvier’s beaked whale (Ziphius cavirostris) is officially the deepest diver in the sea mammal community, annihilating both the sperm whale and southern elephant seal for the illustrious title. Until now, its diving abilities have been underestimated owing to the […]

DIY Science: Scientists create a LED photometer that can measure the pH of seawater with an accuracy of 0.01, for under $50

Do you own an aquarium with high-maintenance saltwater fish that are happy within a narrow pH range? Maybe you just got your first Arduino (http://www.arduino.cc/) or Raspberry Pi (http://www.raspberrypi.org/) and you want to set up your own rig but don’t know what to do. Or maybe you are a citizen scientist who wants to do […]

Now you see it, now you don’t!

BRMs (Burial Recording Mines) are cylindrical instruments that capture 4-D data of small scale sediment position on the sea floor in intervals as close as every 15 minutes. Scientists can use the information they collect to model the evolution of sediment geomorphology on the sea floor in response to normal and extreme conditions and use […]
