Let it Sludge!

Marine snow has a lot in common with particles that form during waste water treatment. Read on to find out how and why this happens! Laura Zinke I am a PhD student studying sediment geomicrobiology at the University of Southern California. My primary research interests lie deep under the sea studying how microorganisms survive in […]

It’s getting cold in here!

As we here into winter, we notice changes taking place in nature all around us. But what do microbes in the ocean do when it gets cold??? Laura Zinke I am a PhD student studying sediment geomicrobiology at the University of Southern California. My primary research interests lie deep under the sea studying how microorganisms […]

Just breathe…OR NOT: Mercury from hydrothermal vents in bubbles and the air

Mercury is a toxic element that can accumulate in marine organisms, including fish we eat. But how does mercury into marine environments? Here we talk about the findings from Bagnato et al., who found lots of mercury coming from hydrothermal systems, and that it could transfer from the water to the air! Laura Zinke I […]

Going nuclear: radioisotopes from Fukushimi power plant stay in sand for years

Nuclear power plants are often located along coasts. In 2011, one of these power plants, Fukushima Daiichi, was hit by a tsunami. Nuclear meltdown ensued, and radioactive elements were released into the environment. Now, a group of scientists found a new reservoir of radioactive materials left from this accident. Sandy beaches up to 100 km […]

Riding the phage wave: Emerging role of viruses in the ocean

Viruses live in the ocean, where they infect bacteria who also live in the ocean. Ocean viruses are crucial to the ecosystem, but we don’t know very much about how they ‘survive’ in the ocean. Scientists used data from samples collected all over the world, and explored what types of viruses were in these samples. […]

New insights into old events using marine sediment

We talk a lot about what the ocean is doing, but what can it tell us about land? Here, we discuss a study where scientists used modeling and marine sediments to determine how African climate changed in the Saharan! Laura Zinke I am a PhD student studying sediment geomicrobiology at the University of Southern California. […]

Paper or plastic? Policies inspired by research to find a solution to plastic pollution

Paper or plastic? In a lot of grocery stores, this is an innocent question, but recently it’s become a controversial issue. We talk about how plastic pollution research has inspired a barrel of policies, and some of the creative new ways people are trying to clean up the earth! Laura Zinke I am a PhD […]

The oil droplet is quite terrified

Oil Spill Snorkels: Eating oil, breathing electrons, saving the world?

Oil spills are not great for the environment, but some bacteria thrive on eating oil. Scientists have been researching ways to use these natural oil degrading bacteria to clean up oil contaminated areas. A group in Italy adapted graphite rods to encourage marine mud bacteria to degrade oil more quickly. They call this the “Oil […]

Under the Sea(floor): Ocean Drilling and Scientific Discovery

Deep, dark, and mysterious, the ocean seafloor contains clues and records of past life and climates on earth. Understanding the subseafloor is critical to understanding our planet. But how do we reach these muds and rocks that lie beneath? Here we explore the history of subseafloor exploration, and find out about some of the technologies […]

Red dead algae

Life on earth has been evolving for a long time – billions of years! The timing of when different kinds of life developed is controversial, but can tell us about the conditions of earth in the past. A group of scientists in Sweden looked at ancient fossils from India, and found what they describe as […]

So cute!

It’s a trap! African penguins impacted by climate change

Young penguins living along the southwestern coast of Africa typically follow cool, nutrient rich water to find food as they grow up. This used to lead them to ‘delicious’ fish such as anchovies and sardines. However, in this ecosystem – the Benguela Upwelling Zone – climate change and overfishing have reduced these fish populations. This […]

Funny happenings in the tropical Pacific

Nitrous oxide is a powerful greenhouse gas made by environmental microbes. In the ocean, microbes making this greenhouse gas live in zones with little to no oxygen. Scientists always thought that Bacteria were making this gas. Recently, a team from the UK set out to explore this hypothesis in the Eastern Tropical Pacific, and found […]
