Lunar Power Over Methane Emissions
Solid methane hydrates in the Arctic Ocean are slowly leaking methane into the atmosphere, and a team of scientists has discovered that the moon may have a small role in this process. But how? Amanda SemlerI’m a PhD candidate in Earth System Science at Stanford University, and I study how microbes in deep ocean sediments […]
Smog can be a Bog: A Story about Iron in the Air and Ocean
Have you ever wondered where smog goes? A group of scientists investigated where particles of iron start and end up, and what they found out is quite interesting! Daniel SpeerHey! I’m a PhD student at the University of California, Davis studying biophysics. I previously studied organic chemistry (B.S.) at the College of William and Mary. […]
Does history repeat itself?: Investigating the Paleocene-Eocene Thermal Maximum
Everyone knows that Earth’s climate changes. With the rapid increases in human-influenced global warming and ocean acidification, we need to be able to model and predict the future. What if we could use the past? A similar time period called the Paleocene-Eocene Thermal Maximum (PETM) exhibited similar climate changes. Scientists have investigated the PETM and […]
Dust may feed more life in a warmer ocean
Just as our bodies need iron to stay healthy, ocean microbes also need iron to grow. Iron in the ocean largely comes from dust blowing from land, getting sprinkled over the surface ocean and dissolving in seawater. And ocean temperature may be a key factor that controls how much dust gets dissolved into the ocean […]
How does mercury end up in our seafood? (Guest Post by Patricia Myer)
This is a guest post by Patricia Myer. Patricia is a third-year Chemical Oceanography PhD student at the University of Connecticut. She received her BA in Environmental Science from Rensselaer Polytechnic Institute in 2017. Her current research is focused on the environmental factors affecting bioaccumulation of methylmercury into plankton. Diana FontaineI am a PhD student […]
If you can’t stand the heat, get out of the kitchen: An analysis of phytoplankton with changing ocean temperature
If you went to the beach and the water is cold, would you jump in? The same questions pertain to very small creatures called phytoplankton off the coast of Mexico. A group of scientists recently studied the behavior of phytoplankton as the ocean’s temperature due to large weather events like El Niño and found some […]
Too Slick to Stick
Have you ever walked down a dock to look at the boats? How about under the boat? The sides? Chances are you’ve probably seen a few things growing on the boat wherever it is submerged underwater such as barnacles or algae. This is known as biofouling, the unwanted accumulation of plants and animals on a […]
How do greenhouse gases move?: An updated study on nitrous oxide exchange from the ocean to the atmosphere
Our atmosphere is composed of different gases like oxygen, nitrogen, and carbon dioxide. These gases can absorb energy, sent from the sun, reflecting off of the Earth’s surface. While scientists can measure and estimate their amounts in the air, gases have the ability to move between the ocean and the atmosphere. This behavior, while interesting, […]
Ocean acidification and baby “squidlife” crises?
Ocean acidification has been known to cause problems for marine mollusks (like oysters and pteropods), because these animals have shells or hard parts that can weaken as acidity increases. There’s another mollusk though with eight arms and two tentacles that may have a larger bag of tricks with which to cope with acidity, but teasing […]
Superoxide: A Super Sink of Ocean Oxygen
Ever wondered how oxygen gets depleted in the ocean? A new study suggests that a significant fraction is transformed into superoxide – an intriguing molecule that biologists love to hate. Amanda SemlerI’m a PhD candidate in Earth System Science at Stanford University, and I study how microbes in deep ocean sediments produce and consume greenhouse […]
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 […]
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 […]
SURFO SPECIAL: Flame retardants: Not as friendly as we like to think
Jamillez Olmo Classen is a senior at the University of Puerto Rico at Arecibo, majoring in Technology in Industrial Chemical Process. This summer, she worked with Dr. Rainer Lohmann (advisor) and Dr. Jitka Becanova (mentor) studying harmful chemicals and how to properly measure their concentrations in our water supply. Read on below to learn about her work! […]
Pteropods are Ptough: How one of the ocean’s most fragile creatures may cope with climate change
Climate change, due to the increase in atmospheric carbon dioxide from fossil fuel burning, is arguably the most important issue facing our planet. One of the most detrimental changes already in progress is the shifting pH of the world’s oceans, known as ocean acidification. Although the speed with which the planet is changing does not […]
Autonomous Under-ICE Vehicles
Seafloor exploration in areas of thick ice coverage has many obstacles. With careful planning and modifaction of AUV design and recovery methods, explorers are able to map and study the Gakkel Spreading Ridge 4000 meters below the thick Arctic Ice Pack. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine research […]
Deep Iron: Good for the Ocean’s Bones
: Iron isn’t just good for your body – it’s good for the ocean, too. While many studies focus on external sources of iron to the global ocean, Fitzsimmons et al. investigated iron sources coming from deep hydrothermal vents along midocean ridges, and how they might disperse iron and other metals vast distances through the […]
Out of sight, but not out of mind: human created chemicals persist deep in the Arctic Ocean
Human created chemicals can be “too good” at their job, remaining persistent and/or toxic in the environment, well beyond the life span of their commercial use. Read on to explore how DDT was found at depths up to 2500 m in the Arctic Ocean by a team from Stockholm University. Anna RobuckI am a third […]
Fireproofing the Arctic
Chemicals that are stable enough for our everyday use are often remarkably stable in the natural environment as well. This poses a problem because these chemicals can travel far from sources and end up in pristine environments like the Arctic. In the study described here, researchers from Germany and China joined forces to measure one […]
After the Phase Out: Can Banning Toxic Chemicals Rescue Pilot Whales?
When it comes to persistent pollutants, all roads lead to the ocean. Perfluorooctanesulfonic acid (PFOS) is a chemical that has recently gained attention due to its toxic effects and widespread presence in drinking water. PFOS from human products has also become widespread in ocean waters and the creatures who live in them. PFOS was banned […]
Pollutants produced by poriferans: using genetics to fill in blanks about sponge chemical production
Although its easy to mistake a sponge for a furry looking rock, these invertebrates and the microbes that inhabit them have some surprising chemical abilities. Anna RobuckI am a third year PhD student at the University of Rhode Island Graduate School of Oceanography in the Lohmann Lab. My current research interests include environmental chemistry, water […]
