Heard and McDonald Islands, Australia | SpringerLink

Heard Island is 43 km long and 21 km wide. McDonald Islands are a group of uninhabited rocky islets, 40 km west of Heard Island (Encyclopaedia Britannica 2006).Heard Island has approximately 362.5 km 2 of area and the McDonald Island, 2.6 km 2.The site includes the adjacent offshore rocks and shoals and all territorial waters to a distance of 12 nautical

Atmospheric inputs of volcanic iron around Heard and McDonald Islands

Atmospheric deposition of iron (Fe) to anaemic waters in the Southern Ocean (SO) can relieve marine phytoplankton growth limitation. This study reports measurements of enhanced Fe loading to the atmosphere around and up to 500 km downwind from Heard and McDonald Islands, on the Kerguelen plateau.

Iron availability influences nutrient drawdown in the Heard

Heard Island (yellow) and McDonald Islands (purple) station locations were selected based on bathymetric features (Watson et al., 2016) and acoustic flares detected by shipboard echosounder (Spain et al., 2018). Reference stations (green) were located to the west and south of HIMI.

Heard and McDonald Islands | World Heritage Outlook

This includes information about plume interaction with lithospheric plates, in addition to insights into mantle hotspot composition due to the widest range of isotopic compositions of strontium, neodymium, lead and helium known from any oceanic island volcano system. Big Ben on Heard Island is the only known continuously active volcano on a sub

Conservation values in the marine environment surrounding

Heard Island and McDonald Islands (HIMI) are an external Territory of Australia, located approximately 4000 kilometres southwest of Australia in the southern Indian Ocean. One of the worlds largest highly protected IUCN category 1A marine reserves the Heard Island and

Heard and McDonald Islands

Located in the Southern Ocean, this Australian external territory comprises mainly two volcanic islands, Heard Island and the McDonald Islands, featuring stark volcanic landscapes, glaciers, and the highest mountain in Australian territory, Mawson Peak. Significance.

Heard and McDonald Islands

Heard Island and McDonald Islands are located in the Southern Ocean, approximately 1,700 km from the Antarctic continent and 4,100 km south-west of Perth. As the only volcanically active subantarctic islands they ''open a window into the earth'', thus providing the opportunity to observe ongoing geomorphic

Heard Island and McDonald Islands

The Territory of Heard Island and McDonald Islands [2] [3] (HIMI; [4] ISO 3166 region code: HMD, HM, 334; [5]) is an Australian external territory comprising a volcanic group of mostly barren Antarctic islands, about two-thirds of the way from Madagascar to Antarctica.The group''s overall land area is 372 km 2 (144 sq mi) and it has 101.9 km (63 mi) of coastline.

''Missed Opportunity'' on Heard & McDonald Islands Reserve

An alliance of 27 environmental groups* today welcomed the expansion of Australia''s Heard Island and McDonald Islands Marine Reserve near Antarctica, but said the government of Prime Minister Anthony Albanese had missed a rare opportunity to protect globally important feeding grounds for penguins, seals and albatross.

Excess δ3He near McDonald Islands seeps, indicating mantle‐derived input, suggests proximal hydrothermal activity; McDonald Islands flares may thus indicate CO2, methane, and other minor...

Glacial and Hydrothermal Sources of Dissolved Iron (II) in

Plateau—Heard and McDonald Islands. Volcanic activity supplies iron in various forms to the ocean, yet these islands have not been studied in detail. Iron (II) is a short lived yet preferred form of iron for phytoplankton in the ocean. Using iron (II), we show that these closely spaced islands supply iron in different ways.

Glacial and Hydrothermal Sources of Dissolved Iron (II) in

Underwater volcanic vents supply iron near McDonald Island, while glacial runoff supplies iron near Heard Island. Knowing these iron sources is essential for understanding what causes this large phytoplankton bloom at the Kerguelen Plateau, an important ecological hotspot and contributor for regulation of atmospheric CO 2 .

Human activities – Heard and McDonald Islands

Due to the extreme isolation of Heard Island and McDonald Islands (HIMI), together with the persistently severe weather and sea conditions, human activities in the region have been, and remain, limited.
