Less than 10 percent of McMurdo Sound's shoreline is free of ice. [3] During austral winter, McMurdo Sound presents a large expanse of surface ice. In summer, ships approaching the sound are often blocked by various amounts of first-year ice, fast ice (connected to the shoreline), and hard multi-year ice. Subsequently, icebreakers are required ...
Winter Quarters Bay is a small cove of McMurdo Sound, Antarctica, located 2,200 miles (3,500 km) due south of New Zealand at 77°50'S. The harbor is the southernmost port [1] in the Southern Ocean and features a floating ice pier for summer cargo operations. The bay is approximately 250m wide and long, with a maximum depth of 33m.
McMurdo Station is an American Antarctic research station on the southern tip of Ross Island, which is in the New Zealand–claimed Ross Dependency on the shore of McMurdo Sound in Antarctica.

During extreme cold events, you may hear a loud boom and feel like you have experienced an earthquake. However, this event was more likely a cryoseism, also known as an ice quake or a frost quake ...
The presence of polynyas in McMurdo Sound provides an ice-free area where penguins can feed, directly effecting the survival of the Cape Royds penguin colony. [ 17 ] The downward transport of carbon (in the form of marine snow ) from the surface to the seafloor associated with polynya blooms provides the nutrients necessary to sustain rich ...
