The Bloop was one or more icequakes from a large iceberg cracking somewhere between Bransfield Strait and the Ross Sea.

**Most likely** Answers **1** questionPublished0

## Where it stands

**Most likely** Its tests supported it: three pieces of evidence for, one against. It needs two reviews to be accepted.

## What it predicts

- A large tabular iceberg was in open water along the bearing in summer 1997.
- The Bloop's spectrum matches icequakes recorded from known bergs, including A53a, within their natural variation.

## What would rule it out

- No large iceberg anywhere along the recomputed bearing in summer 1997, or a spectrum outside the range of a modern icequake catalogue.
