An unexpected source of deep-sea iron in the Southern Ocean fuels life at the ocean’s surface
The cold, dark Southern Ocean makes it difficult for phytoplankton, the plants of the sea, to get the resources they need to grow, like iron, but new research reveals an unexpected source of iron is from deep-sea vents, read on to find out more. Tricia ThibodeauI am a plankton ecologist focused on the effects of […]

A View from Above: Determining Protein Concentration in Phytoplankton by Satellites
Every animal needs their essential nutrients to survive. If an animal eats phytoplankton, how do they know how much of their nutrients they received? A team of scientists in Busan, Korea investigated the amount of protein in phytoplankton, and their results are quite interesting! Daniel SpeerHey! I’m a PhD student at the University of California, […]

The Need for Speed: The velocities of tides in the Mid-Atlantic
Every 12 hours and 25 minutes, a rush of water move into the coast to create a high tide. How fast does this water move? Currently, global sea levels are rising and it is becoming significantly important to understand how these coastal tides move as millions of Americans live along the eastern seaboard. Two scientists […]

Rugged Southern Ocean phytoplankton weather the storms
Phytoplankton from the “wild west” of the world’s oceans have learned to regrow after storms… over and over and over again. Nyla HusainI’m a PhD student at the University of Rhode Island’s Graduate School of Oceanography. I use a small-scale computer model to study how physical features like surface waves at the air-sea interface produce […]
Phytoplankton Expanding Northward as Arctic Sea Ice Retreats

Read on to learn about how acoustics can capture sounds produced by benthic algae. Katherine BarrettKate received her Ph.D. in Aquatic Ecology from the University of Notre […]
Antarctic Eddies Suck Carbon from the Atmosphere

The results can help us understand and predict how the ocean’s ability to regulate climate might change in the future. Channing PrendI’m a physical oceanography PhD student at Scripps […]
When life gives you global warming, make pancake ice in ocean wave models
Sea ice is retreating, the Arctic is opening up, and wave activity is increasing. What does this mean for the ocean and atmosphere? The refreezing season of autumn may have some answers.

Nyla HusainI’m a PhD student at the University of Rhode Island’s Graduate School of Oceanography. I use a small-scale computer […]
Bergy Bits Are a Bit Burdensome
Icebergs and ‘bergy bits’ have been long studied as carriers of freshwater into the global ocean climate system on global, regional, and local scales. But in previous models, some potentially major factors have been overlooked. There may be more going on under the surface than researchers once suspected. Zoe GentesZoe has an M.S. in Oceanography […]
Growing a Scientist: Undergraduate Research 2017
Each summer, the University of Rhode Island Graduate School of Oceanography (GSO) hosts undergraduate students from all over the country to participate in oceanographic research. These Summer Undergraduate Research Fellows (SURFOs) have not only been working with GSO scientists, but they have spent part of their time learning how to communicate this science to the […]
Dawn of the age of Aquarius…total alkalinity measurements
While not as exciting as the new era of peace predicted by 5th Dimension, it is pretty cool that scientists can measure ocean chemistry from space. The marvels of modern technology, amiright? Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His research in the Jaffe Laboratory for Underwater Imaging focuses on […]
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 […]
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 […]
Listening for Symptoms: A new use for hydrophones in the face of harmful algal blooms
Whales aren’t the only animals hydrophones can detect out in the ocean. In fact, in the near future it might be possible to listen in on animals like scallops and determine if they’re healthy or not. Intrigued? Click here for more! Andrea SchlunkI am a former PhD student from the University of Rhode Island, having […]
