A Circular Sea Ice Puzzle (WEEK 6)

As I mentioned two blog posts ago, I suspect that less surrounding sea ice concentration correlates with higher rates of rift propagation. To determine sea ice concentration (SIC), I downloaded a bunch of data sets that give SIC values (between 0 and 1) in areas of 50,000-by-50,000 meters, and I extracted the values from right around the Amery Ice Shelf. However, clipping the SICs proved to be much harder than clipping the ocean temperatures.

Data in Four Dimensions (WEEK 5)

As I mentioned in the previous blog post, I suspect that warmer ocean temperatures correlate with higher rates of rift propagation. However, throughout the Amery Ice Shelf, the depths of it range from roughly 300 meters at the calving front (point at the end of the AIS, where ice typically breaks off from) to 1,200 meters at the calving front (point at which the ice is no longer attached to the underlying bedrock). Because I do not know how thick the ice is that directly surrounds the rift, I compiled as many relevant depths as I could that could be in contact with that specific portion of the AIS.

The Culprits of the Rift (WEEK 4)

The first part of this project explores the how: how is the loose tooth fork rift on the Amery Ice Shelf changing over time? This is a question that I have outlined throughout the past three blog posts. Now, however, it is time to turn to the second part of this project – the why: why is the loose tooth fork rift experiencing the changes we have observed?

Preliminary Ice Shelf Changes Since the New Millennium (WEEK 3)

In the last blog post, I went into specifics on how I have measured the rifts. Here, I will talk about how I have observed the Amery Ice Shelf to be changing over time.

Turning Pixels of Antarctica into Numbers (WEEK 2)

On my last blog post, I discussed how I went about collecting data. Now that I have a set of satellite images, I will discuss how I have pulled out quantitative data from them.
