For Coral Reef Restoration to Work, Remote Sensing Technology is Key

Technologies that can sense qualities like temperature, ocean color, and the shape of the seafloor from afar have transformed global marine monitoring by providing quick access to ocean data, including information from remote locations. Remote sensing technology is essential for successful coral reef restoration, argues a new study, and that it will only become more […]

When will global warming change the color of the ocean?

Climate change is predicted to transform the ocean – Dr. Stephanie Dutkiewicz and her colleagues want to know how and when global warming will change its color. Julia DohnerJulia is a PhD student at Scripps Institution of Oceanography in La Jolla, California. Her focus is on biogeochemistry, which, as the name suggests, centers on the […]

Where are the Zooplankton?

Ever wonder how researchers combine observations of organisms in the water to what we can see from satellites? Read on for a summary of newly published research by Dr. Jean-Hoel and co-authors. Melanie FeenI am a first year graduate student at the Graduate School of Oceanography at University of Rhode Island. I use robots and […]

Seeing Swarms from Space, Zooplankton in Action

Ever wonder how living creatures in the ocean can be seen all the way from space? A recent study by Basedow and co-researchers found that they could detect red colored zooplankton in images collected by satellites. Melanie FeenI am a first year graduate student at the Graduate School of Oceanography at University of Rhode Island. […]

Rugged Southern Ocean phytoplankton weather the storm(s)

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 4th year PhD student at the University of Rhode Island Graduate School of Oceanography. I use models to study small-scale turbulence at the air-sea interface induced by airflow over surface gravity waves […]

Phytoplankton Expanding Northward as Arctic Sea Ice Retreats

A recent study uses satellite data to show that Arctic sea ice retreat is causing changes in the timing and location of spring phytoplankton blooms, which play a large role in the regional ecosystem and carbon cycle. Channing PrendI’m a physical oceanography PhD student at Scripps Institution of Oceanography in La Jolla, California. I use […]

Monitoring the benthos by listening to photosynthesis

Even though the benthos is a largely unseen energy base for marine food webs, scientists are listening to benthic habitats as a novel way to monitor ecosystem health. Read on to learn about how acoustics can capture sounds produced by benthic algae. Katherine BarrettKate is a 3rd year PhD candidate in the Biological Sciences Department […]

Antarctic Eddies Suck Carbon from the Atmosphere

A recent study from researchers at the University of Tasmania investigates the relationship between ocean eddies and phytoplankton growth in the Southern Ocean using satellite data. 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 4th year PhD student at the University of Rhode Island Graduate School of Oceanography. I use models to study small-scale turbulence […]

Cyanobacteria invasions… from space?

They may not come from space, but they can be seen from up there! Learn how microscopic plants called cyanobacteria accumulate in the Baltic Sea, how they’re measured with satellites, and what it all means. Nyla HusainI’m a 4th year PhD student at the University of Rhode Island Graduate School of Oceanography. I use models to […]

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 […]

To I.D. Debris: LIDAR as a tool to identify trash on the beach

Scientists may have a new option for figuring out how much debris litters our beaches and what it all is! Find out more in today’s World Oceans Day post on marine debris! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I now work in […]

Miles-deep currents seen from miles high

The system of currents that moves water and heat around the globe and regulates global climate may be slowing down. For the first time, researchers are able to track the changes from space. Nicole CoutoI’m interested in how physical processes occurring in different parts of the ocean affect local ecosystems and climate. For my PhD […]

Jump in, the water is warm!

Satellite data was used to measure surface water temperatures throughout Chesapeake Bay over the last 28 years. This new approach will allow us to monitor future water temperature changes from the comfort of home. This study uncovered that Chesapeake Bay water temperatures are increasing faster than air temperatures, which could have negative ecological consequences. Kari […]

Blooming around the world: A story of coccolithophore co-existence

Satellite remote sensing suggests that different phytoplankton species can live in harmony during phytoplankton blooms in the open ocean. Kari St.LaurentI received a Ph.D. in oceanography in 2014 from the Graduate School of Oceanography (URI) and am finishing up a post-doc at the University of Maryland Center for Environmental Science (Horn Point Laboratory). I am […]
