Understanding GPS-Tracked Icebergs in Climate Models
In recent years, the rapid alterations in climate and ocean temperatures have significantly impacted the Greenland Ice Sheet, raising concerns about marine ecosystems and global weather patterns. However, studying the movement of water around and the melting of the ice sheet has been a challenge for scientists due to the potential destruction of equipment by icebergs floating near the glaciers.
Novel Approach: GPS-Tracked Icebergs
A groundbreaking study conducted by researchers at the University of Maine has introduced an innovative method to address these challenges and improve climate models. By attaching GPS devices to icebergs, scientists have been able to track their movements and gather valuable data to enhance the understanding of ocean circulation patterns around glaciers. This unique approach has provided insights into the dynamics of fjord circulation, ultimately contributing to more accurate climate models.
Insights from GPS-Tracked Icebergs
During the summers of 2014 and 2019, GPS devices were used to track the hourly positions of 13 icebergs as they traversed Greenland’s Ilulissat Icefjord towards the ocean. This data, collected by researchers including UMaine assistant professor Kristin Schild and earth sciences professor David Sutherland, has shed light on the impact of freshwater flow from tributary fjords on the circulation in the primary fjord. Such insights are crucial for understanding ocean currents and predicting the potential rise in sea levels.

Implications for Climate Research
The findings from the study have significant implications for climate research and modeling. By incorporating data from GPS-tracked icebergs, scientists can improve the accuracy of their predictions regarding glacier-ocean interactions, sea level rise, and the overall impact of climate change on marine ecosystems. This novel approach not only helps in understanding the complex dynamics of glaciers but also underscores the interconnected nature of environmental changes on a global scale.
The utilization of GPS-tracked icebergs in climate models represents a groundbreaking advancement in glacial research. By leveraging these natural phenomena as tools for data collection, scientists have unlocked new possibilities for enhancing the accuracy of climate models and gaining a deeper understanding of the intricate relationships between glaciers, oceans, and climate change. This innovative approach paves the way for more informed decision-making and proactive measures to address the challenges posed by a rapidly changing climate.

Ocean current
An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences. Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and strength. Ocean currents...
