What happens when crude oil spills into the sea?

TL;DR

Crude oil is a complex material formed underground, with varying viscosities and effects on wildlife, especially birds.

Transcript

everyone in the world by now must have heard about the tragic oil spill in the Gulf of Mexico or leak of oil continuing and we thought that it would be interesting to show you what crude oil is really like after much searching around the University my colleague Sam found some samples there here you can see some of them beginning to leak already and...

Key Insights

• 💁 Crude oil is a complex material formed underground from plant and animal matter compressed by rocks.
• 👨‍🎤 Variations in crude oil viscosity depend on the rocks' treatment in a particular location over millions of years.
• 🚾 Oil spills create cleanup challenges as oil floats on water and repels it, covering large areas in a thin layer.
• 🛢️ Wildlife, especially birds, are affected by crude oil as it disrupts the natural oils on their feathers, affecting their ability to stay afloat and regulate body temperature.
• 😌 Surfactants, like soap, can be used to clean oil from birds' feathers, but the challenge lies in ensuring it does not harm the wildlife in the process.
• 🚾 The scale of oil spills poses challenges, with slicks covering vast areas of water that require extensive cleanup efforts.
• 🚾 Understanding the properties of crude oil and its interaction with water is crucial for addressing environmental impacts of oil spills.

Questions & Answers

Q: How is crude oil formed?

Crude oil is formed under the ground at great depths from compressed layers of plant and animal material under rocks over millions of years.

Q: What happens when oil mixes with water during an oil spill?

Crude oil floats on water as it is less dense, forming a thin layer on the water's surface, making cleanup challenging and harmful to wildlife.

Q: How does crude oil affect wildlife, particularly birds?

Crude oil can harm birds by disrupting the natural oils on their feathers, leading to clumping of feathers, loss of water repellency, and potential hypothermia.

Q: How can oil from birds' feathers be cleaned during an oil spill?

Surfactants, similar to soap, can be used to form tiny droplets of oil that do no harm, but the challenge lies in ensuring these surfactants don't harm the birds in the process.

Summary & Key Takeaways

• Crude oil is a complex material formed from plant and animal material compressed by rocks.

• Different locations have different types of crude oil with varying viscosities.

• Oil spills pose cleanup challenges as oil floats on water and repels water, causing harm to wildlife like birds.
