Smog can be a Bog: A Story about Iron in the Air and Ocean

By Daniel Speer ⋅ November 24, 2020 ⋅ Post a comment

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

By Daniel Speer ⋅ October 28, 2020 ⋅ Post a comment

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 […]

More than cow burps: the many sources of methane

By Victoria Treadaway ⋅ March 15, 2017 ⋅ Post a comment

Methane is an important, and often forgotten, greenhouse gas. It comes from a variety of sources including wetlands, rice paddies, and natural gas operations. This article explores methane’s role in our changing climate and investigates some natural and anthropogenic sources. Victoria TreadawayI am a PhD candidate at the Graduate School of Oceanography at the University […]

Emissions from International Shipping Vessels Contribute to Ocean Acidification

By Cathleen Turner ⋅ November 4, 2013 ⋅ One comment

Ship emissions of sulfur and nitrogen oxides (SOx, NOx) can be deposited and form sulfuric and nitric acid in surface water. Do heavily-trafficked trade routes result in “hotspots” of ocean acidification? Hassellöv and her team show “hotspots” that coincide with areas of heavy shipping traffic and seasonal stratification. Cathleen TurnerCat Turner is a Masters Candidate […]

Model Suggests 40% of Global Dioxin Emissions End Up in Oceans

By Carrie McDonough ⋅ October 30, 2013 ⋅ 3 comments

Researchers at the University of British Columbia recently presented a global model simulating how dioxins, a group of very toxic, persistent pollutants, travel from source regions and are deposited around the globe. Their findings suggest that oceans are impacted more dramatically than previously thought. Carrie McDonoughI am the founder of oceanbites, and a postdoctoral fellow […]
