Let Marine Microbes Be Thy Medicine

The deep sea is a treasure trove of disease-fighting compounds–and is even helping us in the fight against the novel coronavirus. Emily ChuaI am a Ph.D. candidate at Boston University where I am developing an underwater instrument to study the coastal ocean.  I have a multi-disciplinary background in physics and oceanography (and some engineering), and […]

The HyperDiver: A New (Hyper-) Intelligent Way to Map the Ocean

German researchers have developed a new system–based on sophisticated imaging technology and artificial intelligence–which promises to revolutionize how we map coral reefs. Emily ChuaI am a Ph.D. candidate at Boston University where I am developing an underwater instrument to study the coastal ocean.  I have a multi-disciplinary background in physics and oceanography (and some engineering), […]

Deep Breathing Underwater

The Labrador Sea is one of the lungs of the ocean. A new study finds that it is taking an even deeper breath than expected—making it more vulnerable to climate change than thought. Emily ChuaI am a Ph.D. candidate at Boston University where I am developing an underwater instrument to study the coastal ocean.  I […]

The secret life of cheese: how dairy can support biofuel production

Did you know that phytoplankton can be used for biofuels? They provide a good alternative to fossil fuels because they can grow very quickly and are rich in lipids and carbohydrates. Lipids are extremely rich in energy and carbohydrates can be converted to sugar which is then fermented to make fuel. In fact, a recent […]

A High-Flying Aquatic Robot

Inspired by the flying squid, researchers have built a robot that can launch itself from the water surface using water-reactive fuel. Emily ChuaI am a Ph.D. candidate at Boston University where I am developing an underwater instrument to study the coastal ocean.  I have a multi-disciplinary background in physics and oceanography (and some engineering), and […]

Sailing Solo: An alternative way to monitor harmful algal blooms

Have you ever heard about a harmful algal bloom? Do you know what causes them? Or how scientists monitor them? Read on to learn about how a group of scientists from Mote Marine Lab in Florida paired up with Navocean, Inc to create the first autonomous small sailboat to monitor blooms in coastal, shallow water […]

The HyperDiver: A New, (Hyper-) Intelligent Way to Map the Ocean

Coral reefs are facing unprecedented change. A new high-tech, diver-operated imaging system promises to be the future of coral reef monitoring. Emily ChuaI am a Ph.D. candidate at Boston University where I am developing an underwater instrument to study the coastal ocean.  I have a multi-disciplinary background in physics and oceanography (and some engineering), and […]

Walking on a Fine Line

What is a WireWalker? You might initially picture someone walking along a tightrope across some crazy abyss. From an observational oceanographer perspective, Wirewalkers are a type of marine robot we use to collect data in the ocean. Instead of walking horizontally, the Wirewalker traverses up and down a wire from the surface to the deep […]

Seasonal Ice Melt Shows Signs of Blooms

Floats collected data underneath the ice during the winter and when the ice melted there were signs of phytoplankton blooms! Check this article out to learn more about why this occurs and how it was detected! Melanie FeenI am a first year graduate student at the Graduate School of Oceanography at University of Rhode Island. […]

Turtles unbothered by close drone monitoring, while birds and crocodiles flee

Bevan E, Whiting S, Tucker T, Guinea M, Raith A, Douglas R (2018) Measuring behavioral responses of sea turtles, saltwater crocodiles, and crested terns to drone disturbance to define ethical operating thresholds. PLoS ONE 13(3): e0194460. https://doi.org/10.1371/journal.pone.0194460 Unmanned aerial vehicles, more commonly known as drones, are quickly gaining popularity as cost effective tools for conservation […]

Small scale, big effect

Processes in the ocean and climate happen at all sorts of size scales. New research out of NASA’s Jet Propulsion Laboratory suggest that small physical features in the ocean might have a big effect on the global climate. Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His research in the Jaffe […]

MAC-EXP: A new sediment corer designed to maintain in situ pressure conditions

The MAC-EXP, a pressure-coring experimentation and cultivation system, was designed to advance our ability to analyze the microbial processes in the deep-sea sediments, which is typically a challenge because the pressure change upon recovery can alter the in situ state. Jackson et al. (2017) describe the result of the systems first field trials. Anne M. […]

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 […]

Degrees of separation: How warm do we think Earth is going to get, really?

The Earth is warming up. But by how much? For some time, climate scientists could not reconcile the varying temperature ranges being published in different studies. But it is time to bury the hatchet, for we have now have a consensus! Read on to learn more… Prabarna GangulyI’m a fourth year PhD candidate in the […]

BAD BOYZ 2.0. Emerging environmental contaminants

Our generation is facing environmental challenges not only from commonly-known contaminants, but also emerging ones, which have been lurking in the shadows until recently. Check this week’s post to know more about these (sometimes surprising) pollutants, and their effects! Prabarna GangulyI’m a fourth year PhD candidate in the Department of Psychology at Northeastern University. My […]

Ctrl+P: 3D printing applications for oceanography

3D printing and oceanography? Check out the fascinating new research advancements made in ocean sciences using one of the most innovative technologies of the 21st century! Prabarna GangulyI’m a fourth year PhD candidate in the Department of Psychology at Northeastern University. My research focuses on the impact of early life stress in the form of […]

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, […]

Under the Sea(floor): Ocean Drilling and Scientific Discovery

Deep, dark, and mysterious, the ocean seafloor contains clues and records of past life and climates on earth. Understanding the subseafloor is critical to understanding our planet. But how do we reach these muds and rocks that lie beneath? Here we explore the history of subseafloor exploration, and find out about some of the technologies […]

The Entire Ocean in a Drop

Article: Stoeckle MY, Soboleva L, Charlop- Powers Z (2017) Aquatic environmental DNA detects seasonal fish abundance and habitat preference in an urban estuary. PLoS ONE 12(4): e0175186 Effectively managing fish populations requires accurate and timely monitoring data. Scientists and environmental managers need to know when (presence/absence data), where (location data), and how many fish (abundance […]
