Holme Bay
Holme Bay is a bay in Antarctica in Mac. Robertson Land, wide, containing many islands, indenting the coast north of the Framnes Mountains. Holme Bay is largely snow-free and was mapped by Norwegian cartographers from aerial photographs taken by the Lars Christensen Expedition in January-February 1937, and named Holmevika because of its island-studded character ('' holme'' means "islet" in Norwegian) .

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giganteus Island
Giganteus Island lies just north of the Rookery Islands in the west part of Holme Bay, MacRobertson Land. Mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37. A giant petrel (''Macronectes giganteus'') rookery was observed by ANARE on the island in December 1958, hence the name.

Mebibyte
The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. To disambiguate arbitrarily sized bytes from the common 8-bit definition, network protocol documents such as The Internet Protocol () refer to an 8-bit byte as an octet. Those bits in an octet are usually counted with numbering from 0 to 7 or 7 to 0 depending on the bit endianness. The first bit is number 0, making the eighth bit number 7. The size of the byte has historically been hardware-dependent and no definitive standards existed that mandated the size. Sizes from 1 to 48 bits have been used. The six-bit character code was an often-used implementation in early encoding systems, and computers using six-bit and nine-bit bytes were common in the 1960s. These systems often had memory words ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mawson Station
The Mawson Station, commonly called Mawson, is one of three permanent bases and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Mawson lies in Holme Bay in Mac. Robertson Land, East Antarctica in the Australian Antarctic Territory, a territory claimed by Australia. Established in 1954, Mawson is Australia's oldest Antarctic station and the oldest continuously inhabited Antarctic station south of the Antarctic Circle. Mawson was named in honour of the Australian Antarctic explorer Sir Douglas Mawson. Mawson was listed on the Register of the National Estate in 2001 and listed on the Commonwealth Heritage List on 22 June 2004, reflecting the post-World War Two revival of Australia's scientific research and territorial interests in Antarctica. Purpose Mawson Station is a base for scientific research programs including an underground cosmic ray detector, various long-term meteorological aeronomy and geomagnetic studies, as well as ongoing cons ...

Williams Rocks
The Williams Rocks are a group of islands, being essentially rocks located north of Flat Islands and Holme Bay, off the coast of Mac. Robertson Land. The Williams Rocks were mapped by Robert G. Dovers of the ANARE in 1954. The Williams Rocks were named by the ANCA for J. Williams, assistant diesel mechanic at Mawson Station in 1962, who assisted in a triangulation of the Williams Rocks and the erection of a beacon.

Welch Island (Antarctica)
Welch Island is an island, long with a prominent pinnacle rock of , lying north of the Rouse Islands and off the eastern side of Holme Bay in Mac. Robertson Land, Antarctica. It lies south of Welch Rocks. Discovery and naming Welch Island was discovered in February 1931 by the British Australian and New Zealand Antarctic Research Expedition (BANZARE) under Sir Douglas Mawson, who named it for B. F. Welch, Second Engineer on the RRS ''Discovery''. Important Bird Area A 415 ha site comprising Welch Island, neighbouring Klung Island, and the intervening smaller islands and marine area, has been designated an Important Bird Area (IBA) by BirdLife International because it supports about 36,000 breeding pairs of Adélie penguins, based on 2012 satellite imagery. Snow petrels breed on high ground on the islands. The islands are mostly ice-free in summer and several lakes are present.

Rouse Islands
The Rouse Islands or Rouse Rocks are a small group of islands in the eastern part of Holme Bay in Antarctica, fringing the coast of Mac Robertson Land close south of Welch Island. The Rouse Islands have an elevation of . The Rouse Islands were discovered on February 13, 1931, by the British Australian and New Zealand Antarctic Research Expedition (BANZARE) under Sir Douglas Mawson, who named them for E. J. Rouse of Sydney, who assisted the expedition with photographic equipment. The Rouse Islands have since been found to be islands.

Rookery Islands
The Rookery Islands are a group of rocks and small islands in western Holme Bay, north of the David and Masson Ranges, on the Mawson Coast of Mac.Robertson Land in East Antarctica. The largest in the group are Giganteus Island in the north-west, 600 m long by 400 m wide, and Rookery Island in the south, 1 km long and 250 m wide. The islands are rocky and of low relief, rising to heights of 60 m on Rookery Island, 25 m on Giganteus Island, and ranging from 10 – 30 m on the smaller islands. The nearest permanent research station is Australia's Mawson, some 15 km to the east in Holme Bay. Environment The group contains breeding colonies of Adélie penguins, Cape petrels, snow petrels, southern giant petrels (which breed nowhere else in the region), Wilson's storm petrel Wilson's storm petrel (''Oceanites oceanicus''), also known as Wilson's petrel, is a small seabird of the austral storm petrel family Oceanitidae.

Nelson Rock
Nelson Rock is an uninhabited solitary island, being essentially a dark rock which is partly ice-covered and lies north of Williams Rocks, off the coast of Mac Robertson Land in Holme Bay. The Rock was mapped by Robert G. Dovers of the Australian National Antarctic Research Expeditions (ANARE) in 1954. Nelson Rock was named by the Antarctic Names Committee of Australia (ANCA) for Robert Edward Kelvin Nelson, a weather observer at Mawson Station in 1962, who assisted with the triangulation of Nelson Rock and the erection of a beacon.

Jocelyn Islands
The Jocelyn Islands are a group of islands lying between the Flat Islands and the Rouse Islands in the eastern part of Holme Bay, Mac. Robertson Land, Antarctica. The group, which is made up (going west-to-east) the Lee Island, Verner Island, and Petersen Island, were mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37, and named Meholmane (the middle islands). They were renamed in 1960 by Australian National Antarctic Research Expeditions (ANARE) for Jocelyn Terry, who for a number of years broadcast news and messages to Antarctica from Radio Australia.
