Vegetation Index of Cape York Peninsula, Australia

12.8S 142.1E

April 6th, 2012 Category: Vegetation Index

Australia - April 4th, 2012

The vegetation index of the Cape York Peninsula, in the northern part of Queensland, Australia, appears mostly good (green) in this FAPAR image. The index becomes lower (yellow) as one moves further south. Visible to the north of the peninsula, however, is part of the island of New Guinea, which shows a much higher index of photosynthetic activity (rusty red).

Australia - April 1st, 2012

This FAPAR image shows the vegetation index of the Cape York Peninsula, in the far north of Queensland, Australia (below) and the island of New Guinea (above). About half of the land of the Cape York Peninsula is flat and used for grazing livestock, however there are also relatively undisturbed eucalyptus wooded savannahs and tropical rainforests. Here, most of the peninsula shows a good (green) vegetation index. Papua, Indonesia (upper left) shows the highest vegetation index (rusty red), while Papua New Guinea (upper right) is slightly lower although higher than the Cape York Peninsula to the south.

Vegetation Index of Western New Guinea, Indonesia

New Guinea - January 12th, 2012

This FAPAR image shows the vegetation index of the island of Western New Guinea, the western half of the island of New Guinea that belongs to Indonesia. A central east-west mountain range dominates the geography of New Guinea, over 1,600 km (1,000 mi) in total length. Here, the vegetation index is lowest (yellow) by the peaks of this range.

Another major habitat feature is the vast southern and northern lowlands. Stretching for hundreds of kilometres, these include lowland rainforests, extensive wetlands, savanna grasslands, and some of the largest expanses of mangrove forest in the world. Here, the vegetation index is highest to the west (rusty red) and mostly good (green) on the right side of the image, in those southern and northern lowlands.

Sediments and Possible Phytoplankton Growth in Arafura Sea and Gulf of Carpentaria – August 22nd, 2011

August 22nd, 2011 Category: Image of the day, Phytoplankton, Sediments

Australia and New Guinea - August 2nd, 2011

Sediments and possibly phytoplankton growth color the Arafura Sea (above) and the Gulf of Carpentaria (below). The sediments are particularly concentrated along the coasts of the Gulf and of New Guinea (top).

The Arafura Sea lies west of the Pacific Ocean, overlying the continental shelf between Australia and New Guinea. It is bordered by the Torres Strait and through that the Coral Sea to the east, the Gulf of Carpentaria to the south, the Timor Sea to the west and the Banda and Ceram seas to the northwest.

It is 1,290 kilometres (800 miles) long and 560 kilometres (350 miles) wide. The depth of the sea is primarily 50-80 metres (165-265 feet) with the depth increasing to the west. As a shallow tropical sea, its waters are a breeding ground for tropical cyclones.

Vegetation Index of Papua, Indonesia’s Rainforests

Papua, Indonesia - February 6th, 2010

Papua, Indonesia - February 6th, 2010

This FAPAR image shows the vegetation index of Papua, the largest province of Indonesia, comprising a majority part of the western half of the island of New Guinea. Most of the province shows good photosynthetic activity (green), with the highest activity (red) visible to the west near the border with the province of West Irian Jaya (West Papua).

A central east-west mountain range dominates the geography of New Guinea, over 1600 km in total length. The western section is around 600 km long and 100 km across. The province contains the highest mountains between the Himalayas and the Andes, rising up to 4884 m high, and ensuring a steady supply of rain from the tropical atmosphere. The tree line is around 4000 m elevation and the tallest peaks contain permanent equatorial glaciers,  although these are melting increasingly, due to a changing climate.

Various other smaller mountain ranges occur both north and west of the central ranges. Except in high elevations, most areas possess a hot humid climate throughout the year, with some seasonal variation associated with the northeast monsoon season.

The third major habitat feature are the vast southern and northern lowlands. Stretching for hundreds of kilometers, these include lowland rainforests, extensive wetlands, savanna grasslands, and some of the largest expanses of mangrove forest in the world.
