Mathematician uses skills to study Greenlands retreating glaciers

David Holland, supported by the National Science Foundation, conducts research on Greenland's fjords to understand the interaction between warm ocean currents and glaciers. His team collects data on salinity, temperature, and pressure to study the effects of warm water on glacier melting, which contributes to sea level rise. The research aims to improve climate models by providing accurate data, crucial for predicting future climate changes. Holland's work highlights the importance of understanding glacier dynamics to anticipate the impact of climate change on sea levels.

What is the primary focus of David Holland's research team in Greenland?

• Developing new underwater vehicles

• Mapping the fjord's underwater terrain

• Exploring new underwater species

• Studying the effects of warm water on glaciers

What has been observed about the Yakob Shaban glacier since 1997?

• It has split into two glaciers

• It has advanced significantly

• It has remained stable

• Its retreat has accelerated

How do natural atmospheric cycles and human activities affect the warm water currents?

• They reverse the direction of the currents

• They contribute to the currents flowing towards the glacier

• They have no effect

• They cause the currents to cool

Why is collecting data with probes important for climate models?

• To reduce the cost of research

• To ensure models are based on accurate data

• To create more complex models

• To eliminate the need for human researchers

What is the ultimate goal of improving climate models according to David Holland?

• To develop new mathematical theories

• To increase the size of the Greenland ice sheet

• To stop glacier melting completely

• To predict the future climate of the planet
