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 […]

The physics of tiny jellyfish hunting

Tiny jellyfish live, swim, and eat in a viscous environment. How they capture their food is something of a mystery. A University of Oregon group took advantage of several fancy imaging techniques to shed some light on the matter. Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His research in the […]

The dark side of the…cephalopod eye?

Cephalopods are among the most colorful creatures in the ocean but only see in black and white. A father/son team recently proposed a new theory explaining how these organisms might sense and understand color. Besides explaining a decades old mystery, their idea might force us to reconsider what it means to see in color. Eric […]

Pluto perhaps not so icy after all

Pluto, the ex-planet at the far reaches of our solar system, recently had a nice photo op as a NASA vehicle drifted by. The pictures gave an unprecedented view of the object and, perhaps, point to the presence liquid water. Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His research in […]

Paleo-oceanography from satellite data reveal ancient tsunamis…on Mars?!

Extraplanetary tsunamis. Need I say more? Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His research in the Jaffe Laboratory for Underwater Imaging focuses on developing methods to quantitatively label image data coming from the Scripps Plankton Camera System. When not science-ing, Eric can be found surfing, canoeing, or trying to […]

Double, double methane and trouble: Quantifying natural and man-made methane seeps

Researchers from Texas A&M and Woods Hole tested out a new, 3D camera system designed to look at deep sea methane seeps. The high resolution, high frame rate videos yielded new insights into bubble dynamics that could influence how we respond to oil and gas spills. Eric OrensteinEric is a PhD student at the Scripps […]

Coral! At The Disco: Using fluorescence (and computer science) to label reef data

A group of scientists and engineers have leveraged two emerging technologies to develop a new system for studying coral in their natural habitat. The team dramatically improved automatic labeling of coral images by combining a novel camera set up with powerful machine learning techniques. The result is fast, accurate, and has the potential to change […]

Arctic could become more biologically productive as ice melts

As Arctic sea-ice melts away, organisms will be exposed to more light and, potentially, more nutrients. Recent model work suggests that this combination will result in a more biologically active Arctic. But the net result might not be as positive as you think. Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. […]

One person’s noise, is another person’s data

Measuring the heat content of deep ocean waters is critical to understanding how our global climate system works. It is also very difficult to do on a large scale. A group at the University of Georgia recently proposed a new technique to take the temperature of the deep ocean using only ambient noise and passive […]

Ringing in the New Year

Join us as we “Ring in the New Year” with a series of posts about sound in the ocean. Learn about the neat things sound does in the sea and how scientists use it to learn about all kinds of interesting phenomena. Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His […]

Kelp: It’s whats for dinner (or where you live)

Kelp is a kind of large algae that supports diverse ecosystems. These kelp forests may start receding as a result of ocean warming. How the organisms that live in these forests respond to the warmer environment and damaged kelp may determine how quickly that happens. Eric OrensteinEric is a PhD student at the Scripps Institution […]

If it you can’t stand the heat, get out of the kelp forest!

Kelp is a kind of algae that supports diverse ecosystems in the nearshore ocean. As the climate and ocean warms, however, these kelp could begin to die off. How, when, and why the kelp die has important consequences for species diversity that will affect ecosystem and fisheries management. Eric OrensteinEric is a PhD student at […]

There’s a storm coming, Plankton. And we all best be ready when she does.

Oceanographers have long known that large storms cause changes in the near-shore ocean environment. But how those changes effect the marine ecosystem is still a grey area. A new study out of Texas A&M sheds some light on how plankton, the tiny creatures at the base of the food web, respond to these large atmospheric […]

Eating Snow: How detritus gets broken down

Marine snow is a critical part of the ocean ecosystem. Much of this carbon rich matter ends up in the deep ocean or on the sea floor. But what about the rest of it? Read on to find out! Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His research in the […]
