Sunrise Over Solitary Island Marine Park
Sunrise (or sunup) is the moment when the upper rim of the Sun appears on the horizon in the morning. The term can also refer to the entire process of the solar disk crossing the horizon and its accompanying atmospheric effects. Terminology Although the Sun appears to "rise" from the horizon, it is actually the ''Earth's'' motion that causes the Sun to appear. The illusion of a moving Sun results from Earth observers being in a rotating reference frame; this apparent motion is so convincing that many cultures had mythologies and religions built around the geocentric model, which prevailed until astronomer Nicolaus Copernicus formulated his heliocentric model in the 16th century. Architect Buckminster Fuller proposed the terms "sunsight" and "sunclipse" to better represent the heliocentric model, though the terms have not entered into common language. Astronomically, sunrise occurs for only an instant: the moment at which the upper limb of the Sun appears tangent to the horizon ...

East Australian Current
The East Australian Current (EAC) is a warm, southward, western boundary current that is formed from the South Equatorial Current (SEC) crossing the Coral Sea and reaching the eastern coast of Australia. At around 15° S near the Australian coast the SEC divides forming the southward flow of the EAC. It is the largest ocean current close to the shores of Australia. Behaviour The EAC reaches a maximum velocity at 30° S, where its flow can reach 90 cm/s. As it flows southward it splits from the coast at around 31° to 32° S. By the time it reaches 33° S it begins to undergo a southward meander while another portion of the transport turns back northward in a tight recirculation. At this location the EAC reaches its maximum transport of nearly 35 Sv (35 billion liters per second). The majority of the EAC flow that does not recirculate will move eastward into the Tasman Front, crossing the Tasman Sea just north of the cape of New Zealand. The remainder will flow sout ...

Commelina Cyanea
''Commelina cyanea'', commonly known as scurvy weed, is a perennial prostrate herb of the family Commelinaceae native to moist forests and woodlands of eastern Australia, Lord Howe Island and Norfolk Island. The blue flowers appear over the warmer months and are pollinated by bees and flies. Taxonomy ''Commelina cyanea'' was one of the many species initially described by the botanist Robert Brown in his 1810 work ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'' and still bears its original name. The genus name ''Commelina'' was chosen based on the Asiatic dayflower. Linnaeus picked the name in honour of the Dutch botanists Jan and Caspar Commelijn, using the two large showy petals of ''Commelina communis'' to symbolise them. The specific name is the Latin adjective ''cyaneus'', meaning "blue". As well as scurvy weed, alternative common names include (native) wandering Jew, forget-me-not, and creeping Christian.

Digitaria Sanguinalis
''Digitaria sanguinalis'' is a species of Poaceae, grass known by several common names, including hairy crabgrass, hairy finger-grass, large crabgrass, crab finger grass, purple crabgrass. It is one of the better-known species of the genus ''Digitaria'', and one that is known nearly worldwide as a common weed. It is used as animal fodder, and the seeds are edible and have been used as a grain in Germany and especially Poland, where it is sometimes cultivated. This has earned it the name Polish millet. Description It is an annual grass with an inflorescence of up to nine very long, very thin, radiating branches atop its stems. Each branch is lined with pairs of very tiny raceme, spikelets. The inflorescences may be reddish or purplish.

Mangroves
A mangrove is a shrub or tree that grows in coastal saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs, and became widely distributed in part due to the movement of tectonic plates. The oldest known fossils of mangrove palm date to 75 million years ago. Mangroves are salt-tolerant trees, also called halophytes, and are adapted to live in harsh coastal conditions. They contain a complex salt filtration system and a complex root system to cope with saltwater immersion and wave action. They are adapted to the low-oxygen conditions of water ...
