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 […]

Hard Coral or Macroalgae? Coral Reefs May Have Another Option

Most of the time coral reef communities are discussed, it seems the focus is whether they’re dominated by hard coral or algae. It turns out there may be other possible outcomes for reefs in the future. Find out more in today’s oceanbites! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and […]

Citizen Science in the New Year!

Tired of only reading articles about science and wishing you could get out there any join those research teams instead? Well, you don’t need a degree to help out—you can get involved in any number of citizen science initiatives! So, if you feel like chipping in and helping scientists gather data, click here to find […]

Eat Organic at Your Local Gyre Margin

Paper: Letscher, Robert T., et al. 2016. Nutrient budgets in the subtropical ocean gyres dominated by lateral transport. Nature Geoscience, v.9: 815–819 If you were a marine organism looking for some grub, where could you find something nutritious? Nutrients in the ocean accumulate in the bodies of living things, which tend to sink to deeper waters […]

Ocean mapping on a budget

The seafloor is complex and mapping it is difficult because direct observations are hindered because it is underwater. Scientists have developed field methods and remote sensing methods to model the geomorphology of the seafloor but they are either limited spatially or by resolution. A newer method being applied to seafloor mapping is called Structure from […]

Melting ice shelves could be slowing down ocean circulation: Elephant seals lend a flipper to find out

Wanted: Antarctic researchers to study the formation of deep water in the coastal Antarctic seas. Job requirements: Plenty of blubber and a healthy appetite for bottom-dwelling sea creatures. Nicole CoutoI’m interested in how physical processes occurring in different parts of the ocean affect local ecosystems and climate. For my PhD research at Rutgers University (New […]

Ghost ships, adorable flotsam, and measuring surface currents

The ocean is teeming with floating objects. Some of them are creepy, rusted, abandoned boats. Others are cute little bath toys. All are nerdy Halloween costumes waiting to happen! Not to mention their utility as oceanographic tools to learn about currents. Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His research […]

Measuring Wind is for the Birds!

There are a lot of things animals are better at than humans. What if we could get our animal colleagues to help us out with our science? This study uses birds with small GPS backpacks to measure wind speed in a way that humans just can’t! Austen BlairAusten Blair is a MS candidate at the […]
